Opis:
For the purposes of this Issue Paper, metals most commonly found at Superfund sites will be discussed in terms of the processes affecting their behavior in soils, as well as in those of the laboratory methods available to evaluate this behavior. The retention capacity of soil will also be discussed with regard to the movement of metals between the other environmental compartments: ground water, surface water, or the atmosphere. Long-term changes in soil environmental conditions, due to the effects of remediation systems or to natural weathering processes, are also explained with respect to the enhanced mobility of metals in soils.

Opis:
Leaching of heavy metals (Zn, Pb, Cu, Ni and Cr) from hazardous waste originating from steel works (slag) has been investigated. Contaminant leaching behavior from monolithic waste materials in the function of time was examined. There was established the cumulative leaching of elements per surface area of waste material and the impact of the duration of the leachant contact with the waste on the leachability. The types of processes accompanying the release of heavy metals were determined as well. Surface wash-off and dissolution were dominant processes during the leaching of the analyzed elements. Chromium was the only element whose release from the sample was controlled by diffusion when subjected to leaching in a liquid of pH 7. Due to the low levels of heavy metal leaching in relation to their concentrations in the samples, it seems that longer duration of the tank test can contribute to the release of additional amounts of the heavy metals.

Opis:
Heavy metals can come from two types of sources: natural and anthropogenic. Natural origin of heavy metals associated with: volcanic eruptions, weathering of rocks, processes soil - creative, forest fires or evaporation of the oceans. Anthropogenic sources of pollution these elements is primarily the burning of fuels, both in power and heating plants and power plants as well as regional and local municipal boiler houses, as well as in the home. In addition to the natural environment gets heavy metals as a result of non-ferrous metals and iron, waste incineration and transport. The rapid development of technology and the changes that are occurring in the world today largely affect on the environment. One of the primary sources of pollution of the biosphere are industrial plants, which emit both gaseous substances (eg. Carbon monoxide, sulfur and nitrogen) and dust, containing all sorts of toxic substances. For the serious consequences of the development of civilization and industry should be spread include heavy metals [6]. Included in the atmosphere, dust and heavy metals fall to the ground parts of plants and enters the soil. Shall be collected by the roots of plants or animals grazing on the roads and thus incorporated into the food chain. These elements are not biodegradable.

Opis:
Research conducted in many research centers all over the world indicate health threats resulting from the presence of lead in the blood gradually decreases to the permissible amount. Lead accumulation in a living organism results in adverse changes in different body systems, symptoms of which include various behavioral changes. They can be reflected in grades obtained by the child at school. The aim of this paper was to establish whether the blood lead level diversify the boys in the respect of their school performance during consecutive years of primary education. The amount of lead in blood of 94 boys at the age of 10 has been measured; subsequently, the group of subjects was divided into two subgroups; the first one (termed in this paper „L”) comprised students whose Pb-B level was lower than 6 μg/dl (4,846 μg/dl on average) and the second one (termed „H”) comprised boys whose blood level exceeded 6 μg/dl (9,256 μg/dl on average). Academic performance in the arts, scientific subjects, geography and natural science in respective groups was assessed. Said procedure was replicated in respective subgroups after a year when the subjects were 11 years old. It was ascertained that the academic performance of the boys with higher blood lead levels deteriorated in scientific subjects and tended to worsen also in other school subject groups. Performance of the students whose blood lead level was lower in the initial examination remained unchanged or improved.
Badania podejmowane w wielu ośrodkach naukowych na całym świecie, wskazujące na zagrożenia zdrowotne wynikające z obecności ołowiu we krwi, zaowocowały stopniowym obniżeniem dopuszczalnej zawartości tego metalu ciężkiego w organizmie. Konsekwencją jego kumulacji są bowiem niekorzystne zmiany obserwowane w układach wewnętrznych, których jednym z przejawów są m.in. różnego rodzaju zmiany behawioralne. Mogą one przekładać się na oceny uzyskiwane przez dziecko w szkole. Celem niniejszej pracy było określenie czy poziom ołowiu we krwi różnicuje chłopców pod kątem ich osiągnięć szkolnych w kolejnych latach kształcenia w szkole podstawowej. Wykonano pomiar zawartości ołowiu we krwi 94 chłopców 10-letnich, a następnie całą grupę badanych podzielono na dwie podgrupy; pierwszą (zwana umownie „N”), w której znaleźli się uczniowie, których poziom Pb-B był mniejszy niż 6 μg/dl (średnio 4,84 μg/dl) i drugą (W) o zawartości ołowiu we krwi przekraczającej ten poziom (średnio 9,25 g/dl). Wgrupach tych oceniono osiągnięcia w nauce z przedmiotów humanistycznych, ścisłych oraz geograficzno-przyrodniczych. Procedurę tę w wyodrębnionych podgrupach powtórzono w kolejnym roku, a więc wśród 11-latków, Wśród chłopców o wyższej zawartości ołowiu we krwi stwierdzono istotne obniżenie się wyników w nauce przedmiotów ścisłych oraz tendencję do obniżania się ocen z pozostałych grup przedmiotów. Uczniowie, których poziom ołowiu we krwi był niższy w badaniu wyjściowym utrzymali lub podnieśli poziom swoich osiągnięć szkolnych.

Opis:
The present research was carried out with the main aim to evaluate the levels of heavy metals in some contaminated or expected to be contaminated by industrial effluents and some non contaminated soils of district Swabi. A total of 30 soil samples were collected from 15 different selected soil series of Swabi area at 0-15 cm and 15-30 cm depths and analyzed for various chemical properties using standard analytical techniques and for extractable heavy metals Zn, Cu, Fe, Cr, Co, Ni, Cd and Pb using Atomic Absorption Spectrophotometer. All soil samples were found non saline having EC values between 0.13-0.56 dsm-1. Soil reaction or pH value ranged from 7.21-8.60 except Mansabdar soil which had pH value of 9.21. It was found that swabi soil was moderately to strongly calcareous in nature, alkaline in reaction having deficient to marginal in organic matter content. Furthermore all soil samples were found almost adequate in Fe, Cu and Zn for most of agriculture crops. The higher concentrations of Ni (22.21 and 21.9 mg kg-1) and Cr (8.02 and 5.11 mg kg-1) at both surface and sub surface were recorded in Gadoom Amazai soils located near ghee mills and many other industries. Higher levels of heavy metals were observed in contaminated soils as compared with non contaminated soils. Decreased in concentration levels of metals were observed in majority of soils with increase in depth. No correlation was found between AB-DTPA extractable heavy metals and soil chemical properties and it might be due to samples collected from different locations with different thermodynamic characteristics.

Opis:
The research on the effectiveness of removing heavy metals from water solutions by bacteria was carried out at the laboratory of the Institute of Environmental Engineering of the University of Zielona Góra in 2007-2008. The research covered bacterial strains isolated from sludge, soil and water. The tests concerned the effect of 3 heavy metals: Pb (0,1%), Cu (0,1%) and Zn (0,1%). The results prove that due to the presence of heavy metals, the size of colonies was much lowered in comparison with the control pan. Some of the strains, reader doesnt know numbers in the 0,1% concentration of Cu and Zn in the culture scale. It turns out that this concentration was completely hazardous with respect to the growth of those bacterial strains. Considering all the heavy metals under analysis, it was found that Cu had the most hazardous effect on the growth of 4 bacterial strains, then Zn and Pb. Under the influence of 4 bacterial strains, the content of the metals that after 7-day long incubation remained is different depending on metal and bacterial strain. Removing Heavy Metals by bacteria from Water solutions heavy metals by bacteria from water solutions: Pb (34,38%), then Cu (29,69%) and Zn (21,88%). The content of the heavy metals removing by 4 strains was from 65,62% to 78,12%. The biggest amount removing was for Zn (78,12%) and the smallest for Zn (65,62%).

Opis:
Pomace from apples, grapes, blackcurrants, and oranges is a waste product of fruit processing, which is formed during the production of juices. Pomace is a rich source of biologically active compounds such as polyphenols, carotenoids, or vitamins. They also contain pectin, cellulose, lignin, proteins, and minerals. All these components, apart from having many beneficial properties for human health, also show sorption properties towards heavy metal ions. Therefore, this study aimed to evaluate the possibility of removing lead (II) and cadmium (II) ions from aqueous solutions by adding apple, grape, black currant, and orange pomace as well as to determine the adsorption efficiency of selected heavy metals. The studies were carried out in model systems. The results of the research showed that lead (II) and cadmium (II) ions are adsorbed on fruit pomace. The highest removal of cadmium (II) ions was observed in orange pomace and of lead (II) ions in apple pomace. The maximum tested cadmium ions absorption capacity was: 0.117235 mg/g in the case of freeze-dried apple pomace; 0.08618 mg/g in the case of freeze-dried currant pomace; 0.21915 m/g in the case of freeze-dried grape pomace and 0.29549 mg/g in the case of freeze-dried orange pomace. On the other hand, the maximum absorption of lead ions was: 0.457 mg/g in the case of freeze-dried apple pomace; 0.442 mg/g in the case of freeze-dried currant pomace; 0.3445 mg/g in the case of freeze-dried grape pomace and 0.421 mg/g in the case of freeze-dried orange pomace. On the basis of the performed measurements, it can be concluded that the tested waste can potentially be used as a cheap biosorbent for removing heavy metal ions from dilute aqueous solutions.

Opis:
The major goal of this research was to employ honey as a bio-indicator to identify the heavy metal levels in bee honey in the Istog, Drenas, and Kastriot regions. As a result, honey was purposely tested in these locations, and two industrial specific areas were chosen for examination and analysis: Kastriot (Graboc) and Drenas (Vrboc), as these are considered to be among the most industrial polluted areas. A honey sample was also taken in the Istog (Vrell, as a clean area) region in order to compare not just honey, but also the area where the bee obtains nectar, as well as the sources of pollution discharge into the environment. Concentrations of heavy metals in honey, (min. and max.) amounted to: Zn (8.705–9.804 mg/kg), Mn (5.620–5.718 mg/kg), Fe (3.635–3.745 mg/kg) and Cu (2.295–2.299 mg/kg). In contrast, lower concentrations of metals, have been observed for: Ni (0.640–1.126 mg/kg), Pb (0.235–0.268 mg/kg), As (0.107–0.199 mg/kg), Cd (0.040–0.058 mg/kg) and Cr (0.025–0.036 mg/kg) while elements such as; Hg, and Co, are almost undetected. The study of hierarchical clusters revealed several groupings of elements with geogenic and anthropogenic origins. The concentrations of heavy metals selected for honey were compared to standards of other countries, such as Poland and other European Union countries. Samples were taken in October 2020 and September 2021. The concentration of heavy metals was determined using inductively coupled plasma optical emission spectrometry, ICP OES.

Opis:
This study assesses the physiochemical characteristics and heavy metals content of crude oil polluted soils and non-polluted soils from Ohaji/Egbema, Imo State. Soil samples were collected at depths of 0-30 cm at each sampling point and then analyzed using standard analytical methods. Data from the five areas were compared to standards for soils in Nigeria and in World Health Organization (WHO) data banks. The results obtained from the analysis showed an average pH of (4.88 ± 0.02 to 5.02 ± 0.04) for polluted soil and (6.57 ± 0.05 to 6.82 ± 0.03) for non-polluted soil, electrical conductivity (571 ± 1.1 to 592 ± 0.8 µS/cm) for oil polluted soil and (383 ± 0.5 to 415 ± 1.6 µS/cm) for non-polluted samples, moisture content (5.2 ± 0.2 to 9.1 ±0.1 %) for polluted soil and (4.5 ± 0.1 to 4.7 ± 0.3 %) for non-polluted soil samples. There was no significant difference in temperature and organic matter for both the polluted and non-polluted soil samples. The heavy metals analysis results showed Fe3+ (0.615 to 0.989 ppm) for oil-polluted soil samples and (0.0453 to 0.273 ppm) for non-polluted soil samples, Pb2+ (0.017 to 0.180 ppm) for oil-polluted soil and (0.008 to 0.010 ppm) for non-polluted soil. The study reveals that areas that are polluted need urgent remediation if the soil is to be used for agricultural purposes.

Opis:
Protecting the environment requires ensuring such conditions that organisms living in it did not suffer permanent damage to their structures and life functions. This also applies to algae living in the aquatic environment. Some species of water flora especially quickly react to negative stimuli arriving from the environment. Their reactions to experienced stress may be a subtle criterion for assessing the condition of aquatic environment. To this kind of plants belong Chara, which are bioindicators of water quality. Their response to applied environmental stimuli is rapid changes of the electrical parameters of the cell membrane. Our research shows that there is also a change in the intensity of ultraweak luminescence (UWL) generated by these plants. UWL is a phenomenon that continuously accompanies processes occurring in living cells and its intensity is less than the threshold sensitivity of the human eye. The method of measurement of this little known way of Chara's response to environmental stimuli has the advantage that it is completely non-invasive for the test material. Non-invasiveness is due to the fact that the radiation emitted from the samples is measured outside the cell membrane separating the living matter from the surrounding environment. In our study, after exposure to a selected stimulus, three types of responses of plant cells were observed: 1) - after a temporary increase of UWL, there is a return to the level of light corresponding to undisturbed homeostasis (e.g. when ascorbic acid is added to the environment); 2) - after a temporary increase in the UWL, the emission of photons slightly falls and stabilizes at a new higher level of illumination (when the stress stimulus is e.g. lead acetate, the emission intensity is 2.2 times larger than in the beginning); 3) - after a sudden and significant increase of UWL, the high emission level is maintained for many hours (e.g. after adding sucrose follows a 20-fold increase of UWL). UWL curves obtained in our experiments correlate with the changes of entropy corresponding to the disturbance of homeostasis in individual cases, depending on the applied stimulus. Respectively: for 1) - an increase of entropy is temporary and is followed by a return to values before the application of the stimulus, 2) - a lasting change occurs, which consists in an increase of entropy to a new fixed level, 3) - change in entropy is so large that its value exceeds the so-called point of no return, which means that the disorder of homeostasis leads to cell death. The application of luminescence imaging technique Single Photon Counting Imaging (SPCI) to the test cells have revealed that the emission of photons from different parts of the plant has a different intensity. When the plant suffered mechanical damage by cutting pseudoleaves, the emission from the damaged sites increased dramatically. This observation allows the damage to be located. Thanks to SPCI technique, it is also possible to track over time any repair processes. The clear differentiation of UWL kinetics leads to the conclusion that monitoring its intensity can be a good research tool in environmental protection. It makes it possible to determine whether chemicals found in the aquatic environment are harmful to a given species of plants. It can be also assessed whether the degree of the harm threatens the entire population with extinction. Thus, the presented method can be used as an ecotoxicity test.

Opis:
This paper pertains to the influence of decreasing supplementation to transformation of chemical forms of Ni. Zn and Cu during composting of sewage sludge. A universally used supplementing material constituting a rich source of organic carbon is straw. Addition of straw to sewage sludge is aimed at increasing C/N proportion up to at least 15 due to the risk of formation of toxic forms of nitrogen, concentration of which in sewage sludge is exceptionally high. We have presented in this paper the results of speciation research of three elements applying Tessier’s sequential extraction. It’s been proven that decreasing of straw share in the composted mixture with sewage sludge down to the level of C/N value below the admissible value, has a beneficial effect on the allocation of tested heavy metals towards the forms that are permanently bound in compost matrix. A systematic increase of organic (IV) and residual (V) fractions share and decrease of mobile forms of heavy metals content in bioavailable fractions i.e. ion-exchange (I) and carbonate (II) has been ascertained.

Opis:
The dynamics of emission of heavy metals compounds into the air in Vinnytsia region (Ukraine) in 2003-2010 years is analyzed. The level of pollution for compounds of some heavy metals (Cd, Hg) has arisen, for others – has decreased (Pb, Cr) or has not changed (As, Ni). The sources of such pollution are defined according to the amount of the emissions of heavy metals compounds in different sectors of economy. In Vinnytsia region they include transport, industrial plants and municipal sector. Great quantity of transport and hazardous materials are consdered as the reasons of increasing of heavy metals emissions. Usage of more environment friendly resources (e.g. unleaded gasoline, natural gas instead of coal) is defined as the reason of reduction of heavy metals emission.

Z pola o wymiarach 50 x 50 m pobrano próbki gleb z warstwy 0--20 cm w odstępach 10-metrowych jako próby pojedyncze, a poza tym pobrano próbę średnią z 30 nakłuć. Wykonano też 5 odkrywek, z których pobrano próbki z warstw o miąższości 5 cm do głębokości 20 cm i 10 cm do głębokości 80 cm. Określono ich podstawowe właściwości fizyczne (skład ziarnowy, gęstość objętościową) i chemiczne (pH w H2O i KCl, PEW, zawartość CaCO3, straty prażenia), a także zawartość metali ciężkich. Wyniki przeanalizowano pod kątem zmienności powierzchniowej, a także wpływu występujących w podłożu dolomitów kruszconośnych na rozmieszczenie metali ciężkich na różnych głębokościach w profilach glebowych. Stwierdzono, że gleby zawierają w warstwie powierzchniowej znaczne ilości Zn, Pb i Cd, których ilości zmniejszają się wraz z głębokością, lecz ponownie wzrastają w poziomach z domieszką gliniastej zwietrzeliny dolomitów. Sformułowano też uwagi dotyczące definicji zanieczyszczenia gleb i standardów jakości gleb.
In the paper the results of the survey on soils were presented The soil samples were located in a study field in the Olkusz region. Single samples were taken from the fields 50 x 50 m, layer 0-20 cm in distances of 10 meters. Apart from this a mean sample of 30 small samples was taken. There were also 5 excavations made from the layers of 5 cm thickness, up to 20 cm depth and 10 cm up to 80 cm depth. Their basic physical properties were defined (grain composition, volume density) as well as chemical properties (pH in H2O and KCl, PEW, content of CaCO3, losses at roasting) and the content of heavy metals. The results were analysed in terms of surface variability and the influence of ore-bearing dolomites on the distribution of heavy metals in soil profiles of different depth. It was found that, in the surface layers, the soils contained significant quantities of Zn, Pb and Cd. These quantities diminish with depth, but increase again in the levels with the addition of clay-like weathered dolomites. The comments on the definition of soil pollution and standards of soil quality were also made.

Opis:
Environmental pollution particularly heavy metal pollution into aquatic ecosystem has led to multiple damage in almost all life forms. Cadmium is one of the priority pollutant listed by United States Environmental Protection Agency or US EPA that widely known to have an adverse effect to organisms as well as human health. One type of organism that is susceptible to the effects of metal pollution is phytoplankton. Phytoplankton is a group of microalgae that are easy to find and are primary producers in aquatic environments. Phytoplankton plays an important role in aquatic ecosystems because they serve as primary producers. They are representing the water total primary productivity and reinforcing the aquatic life on the higher food chain. Thus, any threats that endangered the population of phytoplankton can lead to trophical cascade or even worse, biodiversity loss. The exposure of cadmium in high concentration to phytoplankton can lead to various impact including cell damage and disruption, biosynthesis inhibition of photosynthetic pigment (e.g. chlorophyll and carotenoid), chlorphyll degradation or known as chlorosis, thylakoid membrane degradation, inhibition of cellular metabolism and cell division. It is important to study the impact of cadmium to phytoplankton in a cellular level to better understand what mechanism lies and to what extent that the cadmium will be transferred to higher trophical organism via bioaccumulation or biomagnification.

The purpose of the work was to determine the relationship between the state of the water environment quality of selected rivers (Zn, Cr, Pb, Cd and Cu tests in bottom sediments), and the sources of pollution resulting from the close proximity to the cities, through which they flow. The following rivers were selected for the study: the Biała river flowing through the city of Białystok, the Narew river flowing through the city of Tykocin and the village of Złotoria, the Supraśl river flowing through the village of Michałowo and Gródek as well as the Biała river flowing through the city of Bielsk Podlaski. The sediments were collected four times from the same points in 2016 in the period from July to October. The sediment samples were collected from the points located on rivers before and beyond towns and villages. The contents of the following metals were tested in the bottom sediment samples: Zn, Cr, Pb, Cd and Cu. The analyses were carried out applying the flame absorption spectrometry method. The statistical multivariate CA and FA analyzes were used. The highest contents of Zn, Pb and Cr were recorded in the bottom sediments from the following rivers: Biała (Białystok) and Biała inflow of Orlanka (Bielsk Podlaski), which resulted from the anthropogenic activity. The research also showed the impact of the agricultural activity due to the slightly elevated Cd level.

Opis:
The overproduction of pollutants resulting from the development of industry causes the deposition of large amounts of toxic and carcinogenic substances, including heavy metals, in the aquatic ecosystem and other ecosystems. This is a civilisation problem of the present times, posing a serious threat to the natural environment, including humans. For this reason, it has recently become extremely important to develop effective methods to minimise the concentration of heavy metal ions in the aquatic systems and thus reduce their negative impact on the environment. One such technique is adsorption, which is believed to be an effective method of removing contaminants such as heavy metal ions from aqueous solutions. Looking at the available literaturę of the last few years, it can be concluded that adsorbents of natural origin are becoming more and more important. These are agricultural waste, all kinds of biomass, and waste from various industries. The study attempts to present and evaluate the sorption capacity of materials of natural origin, including oat bran, chitosan, alginate, tree bark, coconut fibre, and lignin. The use of such biosorbents is more friendly for the environment compared to their synthetic counterparts and perfectly fits the concept of sustainable development and the circular economy.

Opis:
The sewage treatment facility of a paper mill at Konstancin-Jeziorna was opened to process industrial and domestic wastewater. After closure of that mill, the sewage treatment facility had to be rebuilt and modernized. Therefore, it was necessary to analyse the chemical and phase composition of the sediments from facultative lagoons used for biological treatment of wastewater. Eight samples of sediments were taken to identify a general phase composition by X-ray diffraction and ten to determine concentrations of selected main and trace elements with the use of ICP-AES and AMA methods.The analyses showed that the sediments consisted of over 90% of mineral fraction, mainly kaolinite, calcite, and quartz and also neomorphic smithsonite. They contained low quantities of Hg, Cd, Co and Mo, and elevated concentrations of Zn, Ba, Mn and Sr. Comparisons of the obtained mean values with admissible concentrations of metals, as defined by Regulation of the Minister of Environment of 9 September 2002, showed that the mean concentrations of As, Sn, Co, Mo and Ni (and also of Hg and Cr in the southern lagoon) met quality standards for soils in areas under protection (group A). Mean concentrations of Pb (both lagoons), Ba, Cu, Cd (northern lagoon) as well as Cr and Hg (southern lagoon) in sediments are higher. However, they still meet standards for areas usable for agricultural and other purposes (group B). The highest concentrations were recorded for Zn, Cd, Cu and Ba in samples from the southern lagoon. These continued to be lower than all the limits acceptable for industrial areas.

Introduction and objectives. Many epidemiological and experimental studies report a strong role of chemical carcinogens in the etiology of bladder cancer. However, the involvement of heavy metals in tumourigenesis of urothelial carcinoma of the bladder has been poorly investigated. Therefore, the aim of this study was to examine the relationship between chromium (Cr) and bladder cancer. Materials and methods. Chromium concentration in two 36-sample series of bladder cancer tissue and sera from patients with this neoplasm were matched with those of a control group. The amount of trace elements in every tissue sample was determined using atomic absorption spectrometry. This was correlated with tumour stage. Results. While the median chromium concentration levels reached statistically higher values in the bladder cancer tissue, compared with the non-cancer tissue (99.632ng/g and 33.144ng/g, respectively; p<0.001), the median Cr levels in the sera of the patients with this carcinoma showed no statistical difference when compared to those of the control group (0.511μg/l and 0.710μg/l, respectively; p=0.408). The median levels of Cr in the bladder tissue, depending on the stage of the tumour, compared with the tissue without the neoplasm, observed the same relationship for both non-muscle invasive and muscleinvasive tumours (p<0.001 and p<0.01, respectively). Conclusions. This study shows that patients with urothelial carcinoma of the bladder had higher tissue Cr levels than people without tumour, while no difference was found in the Cr serum levels between the two groups of patients under investigation.

Pollution with heavy metals and waters in Mitrovica with surroundings, both in the past and in present days, is a preoccupation for the citizens of Mirtovica, as well as for the other inhabitants living around it. Such a problem has been a concern which still continues for a number of researchers who have been dealing with this issue, and who still continue to be preoccupied with the issue of heavy metal (habitat) pollution in this part of Kosovo. Heavy metal's contamination of the environment's main components, dates back to the 1970s/90s to this date. This pollution, especially of the rivers, is due to the industrial activity taking place in the Trepça Combine and the presence of industrial landfill sites of this Combine near the flow of two main rivers: the Sitnica and Ibër River waters, in the city of Mitrovica. The focus of our study, this time consists solely in the research and illumination of pollution with these heavy metals and waterworks of the Ibër River, as a result of the pollution caused by the industrial waste landfill located in Kelmend village. In the paper, we have attempted to show the concentration of heavy metals in sediment and water, by pointing at four sample sites of the Ibër river: in the Bosniak U1 neighborhood, then in the flow in front the U2 landfill, discharge flows from landfill U3 and a certain distance from the U4 landfill.

The research on the topic of the dissertation was carried out within the coastal (southern) part of the Azov oblique dissected accumulative-denudated plain and the coastal strip of the coast of the Sea of Azov, as well as the valleys of the lower reaches of the Don and Kalmius rivers. The research area covered the modern territory of Taganrog and Rostov-on-Don cities and a suburban area up to 15-20 km away from the borders of these cities. According to the materials of the USSR soil map, as well as modern schemes of soil zoning in Russia, the study area covers the distribution area of ordinary chernozems and partially southern low-humus chernozems on loess rocks. The main zonal soil studied was ordinary chernozem. Ordinary warm chernozems with a short freezing period, belonging to the Azov-Ciscaucasian province of powerful and super-powerful chernozems, predominate in the soil cover of the Azov inclined plain, extending from the Donets Ridge to the shores of the Sea of Azov and the lower Don River.

The results of the research studies concerning binding of heavy metals and arsenic (HM+As), occurring in soils affected by emissions from Głogów Copper Smelter and Refinery, by silane nanomaterial have been described. The content of heavy metals and arsenic was determined by AAS and the effectiveness of heavy metals and arsenic binding by 3-Aminopropyltrimethoxysilane was examined. The total leaching level of impurities in those fractions was 73.26% Cu, 74.7% – Pb, 79.5% Zn, 65.81% – Cd and 55.55% As. The studies demonstrated that the total binding of heavy metals and arsenic with nanomaterial in all fractions was about as follows: 20.5% Cu, 9.5% Pb, 7.1% Zn, 25.3% Cd and 10.89% As. The results presented how the safety of food can be cultivated around industrial area, as the currently used soil stabilization technique of HM by soil pH does not guarantee their stable blocking in a sorptive complex.

Organic and non-organic pollution present in the drilling waste may negatively impact flora and fauna. The tests conducted on earthworms may serve as indicators for the assessment of pollution bioavailability, i.a. heavy metals, polycyclic aromatic hydrocarbons, due to the relatively stable ratios between the concentration of certain pollutants in earthworms and soil. Moreover, earthworms are capable of metal bioaccumulation in tissues; therefore, they can be utilized as an ecological indicator of soil pollution. The studies on bioaccumulation of heavy metals from soils with the addition of drilling wastes in tissues of earthworms were conducted. The reduction percentage (R) of each scenario was calculated for the total concentration of all heavy metals. As data showed, all heavy metal content was reduced from its initial concentration.

The research material was a honeydew, monofloral honey and buckwheat honey. For the mineralization of samples, the following solutions were applied: 1) HNO3(conc), 2) HNO3(conc) and H2O2(conc) in the volume ratio equal to 4:1 and 3:1. On the basis of the results and recommended food standards the percentage of the recommended dietary allowances (RDA) in connection with the consumption of 100 g of product were estimated. To verify the results validation of analytical method used was carried out. It was included defining the following validation parameters values: the limit of detection and quantification; linearity and measurement range; repeatability and accuracy of the results. The contamination of the analyzed honeys by Pb is higher than the acceptable level of contamination of this element. The highest contents of Cu and Zn were characterized by monofloral honeys.

The commonness of metal contamination, even at considerable distances from industrial centers and intensively used economic areas, has become the interest of many researchers. The issue of evaluating the state of the environment with the help of living organisms has become a very important part in the control of the natural environment. Honey bee (Apis mellifera L) is a good bioindicator as it is inextricably linked to the natural environment in which it lives. The aim of the research, and at the same time the main assumption of the study, was to evaluate the effectiveness of honeybees (Apis mellifera L) as bioindicators for the presence of Cu, Cr, Zn, Mn, Fe in the urban area (example of Bialystok city). The study includes pilot studies covering three sampling periods (March, June and September 2015). Analyses of metals were made by ASA method. The results showed the presence of Cu, Cr Zn, Mn and Fe in all bees samples. An increased content of Cr in bees was also found, which may be the result of the presence of this element in the environment (air, soil, water, plants, pollen) and in the impregnation agent applied to protect wooden elements of the bee hive. The research showed seasonal variation of metals in bees bodies. The main sources of studied metals in bee samples seem to be motorization, industry, and municipal economy within the urban area. Statistical calculations showed a common origin of majority of studied metals. Bee studies for metals contents can be an important element of a bio-monitoring of changing natural environment as a consequence of anthropogenic activity.

Opis:
Heavy metals that pose a threat to the environment include lead (Pb), zinc (Zn), copper (Cu), arsenic (As), cadmium (Cd), chromium (Cr), nickel (Ni) and mercury (Hg). Biomonitoring of environmental quality using plants is widely accepted as a reliable and inexpensive way of obtaining information on contamination also by heavy metals. It allows the assessment of the direction of changes in the natural environment and development of prognoses and methods for early warning related to predicted transformations in ecosystems. This paper presents the results of field and laboratory studies on floristic biodiversity in the areas of southern Poland related to extraction and processing of Zn and Pb ores. The paper also shows the selected plant defence mechanisms against the excess of heavy metals and the results of bioindication studies using different plant species, including the selected metallophytes related to the assessment of contamination levels and the most frequently used plant ecophysiological parameters. It is necessary to monitor contamination level, popularize knowledge and take action at the level of local authorities to mitigate adverse effects of human activity, bearing in mind possible bioaccumulation of heavy metals in the food chain and the adverse health effects associated with environmental contamination.

Opis:
Assessment of the assimilability of elements contained in sewage sludge can only be carried out if their fractions, by means of which the chemical form of the element can be identified, are determined. The total content of heavy metals only makes it possible to determine whether the sludge meets the legal requirements and can be used, inter alia, for reclamation, in agriculture or for the adaptation of land to specific needs that result from waste management plans. Therefore, when planning the agricultural use of sewage sludge, attention should be paid above all to the heavy metal fractions contained in it. This is due to the fact that plants do not assimilate every form of element to the same extent. The research and analysis carried out indicate that the metals were most closely related to fractions IV and III, for example they formed connections with silicates, as well as sulphides and organic matter. The metal forms available to plants occupied a small percentage of the total heavy metal content. It was noted that with the metastable fraction of lead increased along with population equivalent. Furthermore, the population equivalent value did not affect the distribution of individual heavy metal fractions in the sludge.

Opis:
Sewage sludge used for reclamation of egraded areas or in agriculture must have a certain total heavy metal content, as required by law. In practice, however, it is important to carry out a fractional analysis of the elements contained in the sludge. This activity allows to determine the chemical form of a given metal, thanks to which it is possible to assess the assimilability of elements by plants. The study proved that the fraction of certain metals in sewage sludge can vary depending on the period studied. The combination of elements with other compounds in sludge from one treatment plant can vary from month to month. Once analysis has been carried out, it should not be the basis for assessing the bioavailability of metals if sludge from a given treatment plant were to be sampled several times a year.

Opis:
Effects of heavy metals on plants result in growth inhibition, structure damage, a decline of physiological and biochemical activities as well as of the function of plants. The effects and bioavailability of heavy metals depend on many factors, such as environmental conditions, pH, and species of element, organic substances of the media and fertilization, plant species. But, there are also studies on plant resistance mechanisms to protect plants against the toxic effects of heavy metals. The microorganisms act in synergism with the plants for effective phytoremediation. This synergistic relationship promotes the exchange of water and nutrients established between plant roots and specialized soil microorganisms thus, enhancing the plant growth. The application of microorganisms in phytoremediation helps to improve plant growth and survival rate. The microbial activity in the contaminated site acts as an indicator for the plant growth and bioremediation. So an attempt were made on the toxic effects of chromium in paddy plants growth and yield and thereby mitigating its toxicity by using microbial inoculants especially Azospirillum.

Opis:
The present study was conducted to assessment the some heavy metals, chromium, cadmium, copper, lead, iron, zinc and manganese concentrations in gill, liver, kidney, intestine and muscle of the selected freshwater fish Tilapia mossambica, Claris batrachus, Labeo rohita, Mystus vittatus and Cyprinus carpio communis of the Veeranam Lake Cuddalore district, Tamilnadu, India collected between January 2010- December 2010. Heavy metals concentrations varied in significantly depending upon the type of fish tissues and locations. In the selected freshwater fish, liver tissues appeared to have significantly highest level of chromium followed by Cd, Cu, Pb, Fe, Zn and Mn. The maximum level of chromium in liver tissue followed by the gill, kidney and intestine was found in the of Tilapia mossambica, Claris batrachus, Labeo rohita, Mystus vittatus and Cyprinus carpio communis while the minimum level of manganese was observed in the muscle tissue of Tilapia mossambica, Claris batrachus, Labeo rohita, Mystus vittatus and Cyprinus carpio communis. These levels of metals higher in the fish tissue may be due to increased fertilizers, agricultural wastes, industrial effluents and some anthropogenic activities high in the investigated area.

Opis:
Concentration of seven (7) metals (Pb, Cu, Zn, Mu, Ni, Cr, and Cd) in the samples of soil and some plant species collected from Kachia military shooting range were determined. The mineral ions were assayed using the acid digestion method and atomic absorption spectrophotometry (AAS). Physicochemical parameters (pH, EC, Bulk density, water holding capacity and Total Nitrogen) of the soil samples were also determined. Of the 7 metals determined in the soils samples, the concentration of Pb (14.85 ± 6.78 mg/kg-1) was the highest compared to the concentrations of other metals. Physicochemical parameters were within the range that allows effective phytoremediation. Cu showed the lowest concentration (0.55 ± 1.68 mg/kg-1). Ni was below the detectable limit in most of the samples. Similarly, concentrations of Pb (12.30 mg/kg-1) in the shoot of Albizia zygia among other metals were higher than those of the other metals in the plant tissues. Concentration of Cd (0.07 mg/kg-1) in the root of Eragotis tremula was the lowest. Generally, metal ion concentration in the soil and plant samples of the shooting range (polluted site) significantly) differed from those of the non-polluted site (P<0.05). Combretum hispidium among the plant species had the highest translocation factor (TF = 2.91). Although the TF was higher in the plant of the polluted site TF >1), reasonable amount of them were retained within the underground tissues (roots).

Opis:
The research concerned flow-through reservoirs fed with contaminated river water. The aim of the research was to recognize the impact of reservoirs on fluvial transportation of contaminants. Three reservoirs, situated in the Upper-Silesian region (southern Poland) and operating in different environmental conditions, were selected for the research: Pogoria I reservoir - operating in the quasi-natural direct catchment (with fluvial load of industrial-municipal wastewater), Przeczyce reservoir - under agricultural anthropopressure, and Dzierzno Due reservoir - under urban-industrial anthropopressure. The research included analyses of the quality of river water flowing into and leaving the reservoirs and calculation of contaminant loads at the inflows and outflows. The research showed that Pogoria I reservoir neutralised inflowing contaminants, thus purifying the river water. Nitrogen and phosphorus compounds were particularly efficiently retained. Electrolytic conductance of water in Pogoria was reduced by up to 50%. Przeczyce reservoir was alimented with eutrophic water (especially rich in biogenic elements) from agricultural land. The reservoir accumulated contaminants at the initial stage of the research. After several years, however, it started releasing some of the accumulated substances, causing an increase in contamination of river water with e.g. organic substances. The data concerning Przeczyce reservoir revealed that reservoirs can purify water from some substances and simultaneously cause an increase in contamination with other substances. Selectivity of hydrochemical impact of reservoirs was particularly visible in case of Dzierzno Due reservoir, which received wastewater from the urban-industrial catchment. It largely reduced the loads of suspended matter, phosphates or zinc, among other substances, at the same time causing secondary contamination with substances like ammonia, lead or cadmium. The results of the research show individuality of reservoirs in terms of their impact on fluvial transportation of substances. It might be believed, however, that each reservoir which is fed with contaminated water will have at least partly (selectively) contaminating impact in the course of time. That should be related to increasing eutrophication in conditions of limited capacity of accumulation of contaminants in the limnic environment. Detailed assessment of transfer of substances by a particular reservoir would require individual research for that reservoir.

Opis:
The aim of the study was to determine soils pollution by heavy metals (Zn, Cu and Cr) and their content in pine needles taken from terrain of Krakow Agglomeration. It was found large changeability of individual trace metals content in analyzed plants and soils material. The metals content in soils amounted to: 12.64–631.9 mg Zn, 1.24–35.06 mg Cu and 2.39–158.9 mg Cr kg–1 dm. The average content of zinc, copper and chromium in soil samples from the city of Krakow terrain was visibly higher than in the analogous material taken from neighboring localities. Variation coefficients of individual trace elements content were: 102.8 % for Cr, 72 % for Zn and 54.2 % for Cu. The highest amounts of analyzed heavy metals was found in soils from places of Krakow Agglomeration located in zones of large intensity of road traffics and in Old Town where the influence of anthropopressure lasts the longest. High their contents were observed also in soil samples taken from the periphery of Krakow and in localities with dense one-family buildings situated along the main traffic routes. The relatively low content of these metals in soils were observed in multifamily dwelling housing estates and in smaller villages from the periphery of the Agglomeration. On average, the most pollution of studied soils with Cu and Zn was found in the eastern part of the Agglomeration, while the lowest in western one. The highest average Cr content was observed in the soil samples taken from northern part of the Krakow Agglomeration while the lowest in southern part. Contents of zinc and copper in soil were significant positively correlated with organic matter content in soil. The average contents of analyzed trace metals in pine needles taken from the city of Krakow terrain and from neighboring localities were differed slightly. The average content of these metals in pine needles from the Agglomeration terrain amounted to: 55.45 mg Zn, 4.76 mg Cu and 2.54 mg Cr kg–1 d.m. Individual metals content in plant was differentiated in diverse extent. The largest variation was found in case of Cr (V = 40 %), lower for Zn (V = 30.8 %), and the lowest in case of Cu (26.4 %). The highest average analyzed heavy metals content was found in needles of pine grown in southern part of the Krakow Agglomeration. The smallest Cu and Cr contents were observed in needles taken from the trees grown in northern part of the city and neighboring localities, while the smallest Zn content was noted in samples from the northern part of the Krakow Agglomeration. Obtained results did not prove a substantial correlation between heavy metals content in soil and in pine needles, what points at origin of Zn, Cu and Cr from deposition from the atmosphere. The bioaccumulation coefficients of analyzed elements had higher values in case of samples taken from countryside than those taken from city Krakow terrain.
Celem pracy było okreoelenie zanieczyszczenia gleb metalami ciężkimi (Zn, Cu i Cr) oraz ich zawartooeci w szpilkach sosen z terenu aglomeracji krakowskiej. Stwierdzono duże zróżnicowanie zawartooeci poszczególnych metali oeladowych w analizowanym materiale glebowym i rooelinnym. Gleby zawierały: 12,64–631,88 mg Zn, 1,24–38 mg Cu oraz 2,39–158,9 mg Cr kg–1 s.m. OErednie zawartooeci cynku, miedzi i chromu w próbkach glebowych z terenu miasta Krakowa były wyższe niż w analogicznym materiale pobranym z okolicznych miejscowooeci. Współczynniki zmiennooeci zawartooeci poszczególnych metali przyjmowały wartooeci: 102,8 % dla Cr, 72 % dla Zn i 54,2 % dla Cu. Najwięcej metali zawierały gleby pobrane z punktów aglomeracji krakowskiej, zlokalizowanych w rejonach o dużym natężeniu ruchu drogowego oraz na terenie Starego Miasta, które najdłużej podlegają antropopresji. Duże ich zawartości zanotowano także w próbkach gleb pobranych na obrzeżach Krakowa oraz w miejscowościach o zwartej zabudowie domów jednorodzinnych, usytuowanych przy głównych szlakach komunikacyjnych. Stosunkowo mało tych metali zawierały gleby z osiedli o zabudowie wielorodzinnej oraz z mniejszych wsi położonych na obrzeżach aglomeracji. Średnio największe zanieczyszczenie badanych gleb Zn i Cu stwierdzono we wschodniej częoeci aglomeracji, a najmniejsze w częoeci zachodniej. Największą średnią zawartością Cr odznaczały się gleby z północnej, a najmniejszą z południowej częoeci aglomeracji krakowskiej. Zawartość cynku i miedzi w glebie były istotnie dodatnio skorelowane z zawartością materii organicznej. Średnie zawartości badanych metali śladowych w szpilkach sosen pobranych z terenu miasta Krakowa oraz z pobliskich miejscowości różniły się nieznacznie. Przeciętna zawartość tych metali w igliwiu sosen rosnących na terenie aglomeracji wyniosła: 55,45 mg Zn, 4,76 mg Cu i 2,54 mg Cr kg–1 s.m. Zawartości poszczególnych metali ciężkich były zróżnicowane w niejednakowym stopniu. Największą zmienność stwierdzono w przypadku Cr (V = 40 %), następnie Zn (V = 30,8 %), a najmniejszą w przypadku Cu (26,4 %). Średnio najwięcej wszystkich analizowanych metali stwierdzono w szpilkach sosen rosnących w południowej części aglomeracji krakowskiej. Najmniej Cu i Cr zawierały igły pobrane z drzew z północnej części miasta oraz z graniczących z nią miejscowości, natomiast najmniejszą zawartość Zn zanotowano w próbkach pobranych w północnej części aglomeracji. Nie wykazano statystycznie istotnej korelacji między zawartością badanych metali w glebie i igliwiu sosny, co wskazuje na ich pobieranie z depozycji z atmosfery. Współczynniki bioakumulacji badanych metali przyjmowały znacznie większe wartości w przypadku próbek pobranych na terenach wiejskich w porównaniu z pobranymi na terenie miasta Krakowa.

Opis:
In the present study, laser-induced breakdown spectroscopy (LIBS) has been applied for the determination of chromium and cadmium contents in wastewater of different canneries surrounding by leather factories. The plasma was generated with a Q-switched Nd:YAG laser having a fundamental wavelength of 1064 nm and delivers maximum pulse energy of 180 mJ. Experimental conditions were optimized to improve the sensitivity and to get a reasonable signal from the generated plasma. The results show that the concentration of chromium and cadmium are varying in different samples depending on the incoming flow of the wastewater from factories. The results from LIBS and standard analytical technique called flame atomic absorption spectroscopy (FAAS) were compared and found in good agreement within the experimental uncertainties.

Simultaneous adsorption of heavy metals in complex multi metal system is insuffnciently explored. This research gives results of key process parameters optimization for simultaneous removal of Cd(II), Co(II), Cr(III), Cu(II), Mn(II), Ni(II) and Pb(II) from aqueous solution (batch system). New lemon peel-based biomaterial was prepared and characterized by infrared spectroscopy with Fourier transformation (FTIR), scanning electron microscopy (SEM), electron dispersive spectroscopy (EDS), while the quantifi cation of metals was made by atomic absorption spectrometry (AAS). Simultaneous removal of seven metals ions was favorable at pH 5 with 300 mg/50 mL solidliquid phase ratio, within 60 min at room temperature with total obtained adsorption capacity of 46.77 mg g–1. Kinetic modeling showed that pseudo-second order kinetic and Weber-Morris diffusion models best describe the adsorption mechanism of all seven heavy metals onto lemon peel.

Opis:
Contamination of soil and water by various heavy metals such as Cd, Pb, Ni, Cu, and Fe is increasing day by day as a result of different activities, such as industrialization and urbanization. Lead (Pb), Cadmium (Cd), and Nickel (Ni) are examples of potential heavy metals that are neither essential elements nor have any role in the process of cell metabolism, but are easily absorbed and accumulated in different parts of a plant and living beings. This study was to investigate the translocation and bioaccumulation of heavy metals such as Pb, Ni, Cd, Cu, and Fe in Urtica dionica L and soil samples from 2 sites (uncontaminated – Koliq and contaminated – Kishnica in the Republic of Kosovo). The results revealed that in the contaminated site, the mean level of all the metals in soil and different parts (root, stalk, and leaf) of the plant were found to be significantly (p < 0.01) higher than the uncontaminated site. Multivariate analysis was used to determine the distribution of metals within the study area. The trace metal contents from different parts of these plants were determined by the use of AAS. The results revealed that Urtica dionica L. translocated high amounts of metals to its organs, especially to leaves, so that translocation factors were much higher than one (> 1). However, these concentrations of heavy metals in the soil and Urtica dionica L were higher than levels specified according to the standards in UK and Germany.

Opis:
This research aimed to determine the physicochemical characteristics and heavy metal concentrations of agricultural soils used for grape and wheat production in Morocco in the Mohammedia Benslimane area. The organic matter (OM) content ranged from 0.6% to 2.93%. The degree of total nitrogen was higher in the wheat plots than in the vine plots in the Mohammedia and Benslimane regions. Total nitrogen average rates ranged from 0.04 to 0.5% and from 0.07 to 0.8% in the vine and wheat plots. These results imply that the soil was silty clay and clay texture, neutral to slightly acidic at all stations. The P2O5 concentrations were 11.15 ppm and 68.14 ppm under the vine and the wheat plots, respectively, while the potassium concentration ranged from 33.1 to 287.9 ppm and from 26.9 to 184.75 ppm under the vine and the wheat plots, respectively. Furthermore, the concentrations of Cd at a few stations exceeded the standard value (2 ppm), reaching 10.375 ppm. The Pb and Zn concentrations were higher in vineyard plots than in wheat plots. The Pb and Zn concentrations were 20.22 ppm and 148.60 ppm, respectively. This study reports updated information on the states of eight stations in Mohammedia and Benslimane. However, further research is necessary to determine the pollution factors in local practice crops and naturally growing plants at these stations to assess their impact on livestock and humans.

The main purpose of this study was to evaluate the effect of treated sewage flowing from sewage treatment plants located in the basin of the Supraśl river on the concentration and load of metals in river waters and its main tributaries. Three measuring- control points were chosen, on the river and its tributaries, located near Gródek, Sokółka and Dobrzyniewo. Selected points were located behind the discharge of treated wastewater from sewage treatment plants respectively – Gródek, Sokółka and Bialystok. The samples of treated sewage and water were collected in a period from May to November, once a month in 2014. Each individual sample was examined for the content of dissolved form of the following metals: Pb2+, Cu2+, Cd2+, Ni2+, Zn2+, Fe2+/3+. After taking into account water flow of the Biała, Sokołda and Supraśl in every month, metals loads expressed in mg·h-1., transported by the Supraśl and its tributaries waters were calculated. In the study monthly metals loads discharged into the Biała, Sokołda and Supraśl by sewage treatment plants in Białystok, Sokółka and Gródek were also calculated. The studies have shown the impact of metals load in treated wastewater on metals loads in waters of studied rivers based on the obtained correlation. Most of the searched relations between loafs of Pb2+ – r = 0,88; Cd2+ – r = 0,98; Fe2+/3+ – r = 0,45; Ni2+ – r = 0,55; Zn2+ – r = 0,86 were obtained in case of wastewater treatment plant in Gródek and Supraśl waters. In the study period we observed a diversity in concentration of Cd2+, Fe2+/3+, Ni2+ and Zn2+ in treated sewage and in river waters, which affected loads of this metals.

The leachability of heavy metals (Cu, Pb and Zn) from the coal fly ash samples was studied. The investigations executed using three leachability tests (USEPA, TCLP, ASTM). The effect of different parameters was determined (the diameter of ash grains, the kind of leaching solutions, pH of leaching solutions, the volume ratio of leaching solutions to the mass of ash samples, and the leaching time) on the leachability of the heavy metals from fly ash samples. Moreover, the influence of pH and changes in the redox potential of the leaching solutions as well as the presence of organic compounds that could potentially form complexes with metals and solubility changes of metals. The concentration of the metals studied (Cu, Pb and Zn) in all obtained solutions was determined by FAAS method. On the basis of the research investigations, optimal leachability conditions for Cu, Pb and Zn from fly ash in this study have been determined. We have also found that pH of the leaching solution, and the presence of organic compounds which have a potential capacity of complexion the metals are the important factors in determining the solubility of Cu, Pb and Zn.

This study deals with seasonal variation of heavy metals in sediments of Muthupet lagoon, Southeast coast of India from September 2011 to August 2012. The bulk sediments were association with sand, silt and clay. Geoaccumulation index (lgeo) was used to quantitatively assess the influences of heavy metal pollution. Heavy metals were determined by using Inductively Coupled Plasma Optical Emission Spectrometer (ICP-OES) and the results were compared to permissible limits of WHO/USEPA. The minimum concentration of heavy metals in all the stations were found during the post monsoon and summer seasons and the maximum concentration of heavy metals in all the stations were found during the premonsoon and monsoon seasons. The reason for the pollution was land drainage, irrigation through channels and municipal wastes and also the peak agricultural activities due to the release of fresh water from reservoirs. Among all the metals iron was found to be maximum in all the stations in postmonsoon and summer season followed by magnesium and manganese. Apart from these three metal, all other six metals are recorded in moderate range. The reason for the high concentration of these metals are anthropogenic activity, agriculture, aquaculture and the rivers regular in and out flow throughout the study duration in the lagoon area.

The aim of this study was to estimate the content of trace elements (Zn, Cu, Cr, Cd, Pb) in soils and consumer plants grown under and without the influence of traffic. The species such as lettuce, raspberry, beetroot, apple, carrot, chives and onion were selected for the study. The samples were mineralized and the heavy metal content in plants and soils was determined by means of atomic absorption spectrometry. The content of heavy metals in the soil from municipal allotments was higher than in the soil from the Saniki Colony. For both samples, the permissible soil content was not exceeded. The amount of trace elements in plants varied depending on species, but the place of vegetables and fruits origin was also important. Most of trace elements occurred in larger amounts in the plants from allotments, and in smaller amounts in the plants from Saniki Colony.

Opis:
Rośliny zielarskie są powszechnie wykorzystywane jako surowce w przemyśle farmaceutycznym. Od czasów starożytnych ziół używa się w leczeniu i zapobieganiu chorób. Jednakże w dzisiejszych czasach mogą one nie spełniać wymagań dotyczących jakości, bezpieczeństwa i skuteczności. Większość produktów ziołowych nie jest testowana, a ich efekty działania są słabo monitorowane. Konsekwencją tego jest niewystarczająca wiedza na temat przebiegu ich działania, skutków ubocznych, przeciwwskazań oraz interakcji z występującymi na rynku produktami farmaceutycznymi oraz żywnością. Przyczyną negatywnego wpływu surowców ziołowych na organizm może być ich zanieczyszczenie przez różne grzyby pleśniowe, powstające podczas zbioru, przetwarzania, przechowywania, a także dystrybucji. Zanieczyszczenie surowców zielarskich może być również spowodowane przez różnorodne metale ciężkie, które występują w wielu aspektach współczesnego życia. Celem niniejszej pracy jest przegląd informacji na temat stanu mykologicznego i chemicznego roślin leczniczych, a także wskazanie kilku ważnych wyzwań związanych z efektywnym monitorowaniem ich bezpieczeństwa.

Opis:
Heavy metals and antibiotics resistance are intense public interest owing to their pollution in the environment and potential deleterious effects on human health. A total of 15 isolates of Bacillus subtilis, Bacillus cereus, Pseudomonas aeruginosa and Escherichia coli (50 manure garden soils) were tested for their resistance against certain heavy metals and antibiotics. Minimum inhibitory concentrations of Pb²⁺, Co²⁺, Cu²⁺, and Zn²⁺ for each isolate were also determined. B. subtilis, B. cereus, P. aeruginosa and E. coli exhibited high tolerance to minimum inhibitory concentrations of 3,200 μg/ml for Pb²⁺, 400 μg/ml for Cu²⁺ and Co²⁺, and 100 μg/ml for Zn²⁺ in agar plates. All the isolates were highly resistant to lead and they showed 100% growth in 3,200 μg/ml concentration. It was observed that all isolates were resistant to a wide range of antibiotics namely clindamycin, ceftazidime, aztreonam and vancomycin.

The chief purpose of this study is to investigate the process of adsorption of heavy metals in sands containing microplastics due to aging and bacterial culture. For this purpose, first, the experiment’s conditions were determined by reviewing previous studies and examining the effects of factors on the duration of bacterial culture and UV radiation. Finally, the test conditions were determined as follows: 25 g of adsorbent in 250 ml solution containing 50 mg/l of lead, cadmium, copper, zinc, chromium, and nickel, 750 micrograms of microplastic, bacterial culture time two days, aging time with UV light 14 days. Results of the study show that the addition of virgin microplastics has little effected on increasing the adsorbent strength, except in the case of nickel which reduces adsorption strength. The aging process increases the absorption of all studied metals by up to 60%. Bacterial culture without an aging process reduces the absorption of nickel and cadmium. Simultaneous use of bacterial culture and aging increases the adsorption power by up to 80% for all metals.

Leachate from public landfill in the city of Tangier, which is neither collected nor treated, could constitute a probable source of pollution of the groundwater table and of those of the Mlalah and Khandak Bou Hajjar wadis in the east, and the Mghogha and Ghir Boudra wadis to the south. This work aims to analyze the level of contamination at Tangier’s municipal waste disposal. The leachate samples were collected and analyzed during the period from 2016 to 2019 and the physicochemical parameters (humidity, pH, organic matter, etc.) were determined on these samples as well as the contents of five heavy metals (lead, cadmium, iron, chrome and zinc). Analysis of the well water shows the presence of polluting elements in the leachate water and a high concentration of metals (especially iron) that exceeds standards. This makes the effluent extremely toxic and thus presents a permanent threat to the health of the local population and the surrounding environment.

Opis:
3-Mercaptopropyl-trimethoxysilane and [3-(2-aminoethylamino)propyl]trimethoxysilane were used to functionalize the surface of silica from Piotrowice in Poland to stabilize heavy metals (HMs) and arsenic in soil. The soil for the study was sampled from the impact zone of Głogów Copper Smelter and Refinery. The soil samples were exposed to five-step Tessier sequential extraction. The speciation studies were limited to five sequentially defined fractions in which metal content was determined. The addition of unmodified silica did not affect significantly the concentration of metals in individual fractions. Significant changes were noted upon introduction of functionalized silica in the soil. The hybrid formulations obtained significantly reduce the release of heavy metals and arsenic from soil sorption complex. The results indicate the potential use of functional formulations for reduction of metal migration in soil in the areas of exceeded concentration of heavy metals and arsenic in the soil, caused by industrial activity.

The results of the research studies concerning the binding of heavy metals (HMs) by quartz sand functionalized with amino silanes have been described. The studies have been carried out on soils sampled from the areas affected by emissions from Copper Smelter and Refinery. The research aims to increase the food safety in the areas of industrial impact. The presence of polyamine chain in the hybrid materials obtained enables a binding of heavy metals (nickel, copper, cobalt). The best results are observed for the hybrid material having four amine groups (four coordination centers) per molecule. For this material the highest content after two extraction cycles (pH 7.0 and 5.0) is observed for copper (98.2%), but for other ions (nickel, cobalt) it is at least 85% of the initial amount of components available for plants.

Opis:
The main purpose of the paper was to determine the influence of catchment management on the bottom sediments quality of small water reservoirs as well as to determine toxic metal content in rushes. Samples of bottom sediments were collected in winter 2013 year, form 4 sediment layers (0-5, 5-10, 10-20 and 20-30 cm) at three points along the body of water. The 48 samples were collected. Soil material was prepared according to the procedures used in soil science, the analysis was performed for the fraction with a particle diameter of less than 1 mm. Plant samples from single species aggregations were randomly cut from 5 to 10 locations of 20-50 m2 area. From these samples the average composite sample was prepared. The total content of such elements as Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Zn was determined by atomic absorption spectrometry (using the Thermo Scientific iCE 3000 series spectrometer) after prior digestion in the mixture (5:1) of concentrated acids HNO3 (65%) and HClO4 (60%). Total Hg content was determined by the AMA 254 analyzer. Between the small water reservoirs adjacent to the areas where organic farming is used, and the reservoirs adjacent to the areas with mineral fertilization there are statistically significant differences in the concentrations of such metals as nickel (layers: 0-5, 5-10, 10-20 and 0-30 cm), as well as cobalt, chromium and iron (in a layer 5-10 cm). It has been found that some plants accumulate higher amounts of heavy metals (average values). Based on obtained results it can be stated that rushes actively captures large amounts of elements reaching studied objects and thereby protect the surface water of the reservoirs from contamination.

The aim of the study was to evaluate the contents of Cd, Pb, Zn and Cu in shoots of willow (Salix viminalis L.) cultivated in the vicinity of a coal ash and slag landfill. The landfill is surrounded by arable lands and meadows. There are two major negative influences of the landfill - dusting and flooding. The result of these interactions is the systematic reduction of agricultural value of the land. A field with an area of 9600 m2 were chosen. The land is located east to the landfill. A total of 40 samples of biomass was collected. The contents of analysed elements were determined by FAAS using a Unicam Solaar M6 spectrometer. Distance from the landfill affects the contents of Cd, Pb, Zn and Cu in the tested willow shoots. However, there is no single concentration pattern for all the investigated metals. An increase in willow cultivation on the described area can bring a good environmental effect and become an example of proper management of the ash and slag landfill neighbourhood.

Opis:
In the paper, the assessment of the impact of heavy metals on water objects, namely copper and chromium was performed, and the methods for their neutralization were defined. A scientifically grounded method for the selection of natural zeolite for the purification of wastewater from heavy metals has been developed, provided that they are jointly present. The physicochemical characteristics of two metals related to heavy metals are presented: copper and chromium. The methods for determining the sorption capacity of natural zeolite for copper and chromium compounds, as well as the methods of analytical control of the wastewater components were presented. The results of the experimental studies on the combined adsorption of copper and chromium cations by natural zeolite under static conditions were presented. The changes in the chemical composition of the zeolite surface as a result of heavy metal sorption have been investigated. The influence of the nature of the ions and the pH of the adsorption medium on the selectivity of the heavy metal ions extraction by zeolite was analyzed. A diagram of the composition of the solution, depending on the pH values, was constructed. The pH of the beginning of deposition of the corresponding heavy metal hydroxides on the zeolite surface was calculated. While analyzing the results of experimental studies on the combined adsorption of copper and chromium ions, it was found that the copper ions are significantly better adsorbed by the sorbent than the chromium ions. Despite the same concentration of the chromium and copper ions in solution, Cu2+ is extracted selectively. As can be seen from the results of experimental studies, the concentration of copper on the surface of the sorbent increases from 0.628% mass at a concentration of 0.01 g/dm3 to 47.380% mass at a concentration of 1 g/dm3. The studies on the static activity of clinoptilolite for the copper and chromium ions indicate a simultaneous mechanism of the process, which involves ion exchange and physical adsorption. The concentration of the chromium ions on the surface of the sorbent after adsorption depends on the increase of the concentration of Cr3+ in the original solution to a lesser extent. The results of the studies on the combined adsorption of the Cu2+ and Cr3+ ions indicate the possibility of their chromatographic separation, which makes their further use possible.

The main river of the Kosovo valley is the Sitnica River, which collects a large number of streams, recipients of wastewaterfrom various urban and industrial centers. The blockage of Sitnica river with waste and non-regulation of the bedding of this river makes this river flood tens of acres of worked ground surface through its course, causing great damage every spring and autumn. Uncontrolled discharge of heavy metals into the contaminated terrestrial environments ensures their transfer to plants, animals and humans and results in an impact on the environment and public health. Determination of the heavy metals concentration level for the assessment of soil pollution along the Sitnica River course was also the main purpose of this study, which was carried out in 2016. For analysis, 8 soil samples were taken at depths of 30–50 cm. From the analysis of the data it was noticed that the content of heavy metals such as Zn, Cd, Pb, Cr in some analyzed samples exceeds the maximum allowed values. The findings indicate high values of metal pollution in the samples taken in meadows as well as the agricultural lands stretching around the river.

The article presents the results of the research from several years of exploitation of the vermiculture plots located in the municipal wastewater treatment plant in Zambrów. It is the only facility in Poland where the vermicompost from municipal sewage sludge has been produced continuously since 2004 (for 16 years). The results of tests of ready-made vermicomposts conducted regularly twice a year (32 tests) were subjected to a simple statistical analysis. The vermicompost analyses of heavy metals, biogenic compounds, organic matter and selected macroelements were compared with the requirements for mineral-organic fertilizers. In terms of the heavy metals content, the highest total content was observed in the first year of plots exploitation, i.e. in 2004, when it amounted to over 1200 mg-1 kg DM. The lowest sum content of heavy metals in vermicomposts, amounting to 398 mg-1 kg DM, was recorded in 2017. The median total content of heavy metals from all observations was 821 mg-1 kg DM. During the whole research period, the content of nutrients in vermicomposts was high, for nitrogen it ranged from 9.8 g-1 kg DM to 31.1 g-1 kg DM (median 14.3 g-1 kg DM), whereas for phosphorus it ranged from 2.1 g-1 kg DM to 14.5 g-1 kg DM (median 5.5 g-1 kg DM). The content of organic matter in the whole several-year study period was high and ranged from 21.3% DM to 59.0% DM (median 33.1% DM). The conducted research confirmed that the use of California earthworm in the process of municipal sewage sludge vermicomposting results in its good mineralization and humification, and the final product (vermicompost) may be a valuable mineral-organic fertilizer.

One of the ways of charcoal producing is its calcination in charcoal kilns called retorts in field conditions. In the charcoal production wood of deciduous trees is being subjected to the process of dry distillation. The process affects the surrounding environment. During the process a lot of pollutants are emitted to natural environment. One of them is ash, which contains heavy metals. The paper aimed at determining the effect of charcoal calcination on heavy metal content in the soil and plant material in the immediate vicinity. Charcoal calcination causes the alkalinization of the soil to 10 metres. In the closest vicinity, the calcination process increases Mn, Cd, Ni and Cu concentrations in the soil material. The influence of charcoal production on the concentrations Fe, Zn, Pb, Cr in soil material cannot be determined unanimously. The effect of the process on heavy metal content in plant material cannot be determined unanimously.

The aim of the study was to evaluate the available waste in view of the heavy metals and fractions thereof. Three waste materials were analyzed in the work, namely dried, granular sludge, digestate from agricultural biogas plant and ash after combustion of biomass from the combined heat and power plant, in terms of the content of heavy metals in them. Their mobility through fractional analysis was determined and the possibilities of their agricultural use were assessed. The analyzed waste was varied due to the pH. Biomass ashes had the highest pH and it was alkaline. The pH of the dried precipitate was neutral and digestate was slightly alkaline. In the analyzed wastes, the content of permissible concentrations of heavy metals determined in the Regulation of the Minister of the Environment was not exceeded. The content of individual elements varied and depends on the type of waste tested. The conducted sequential analysis showed that various metal fractions are present in the tested wastes. The content of heavy metals in individual factions was varied and the content of mobile and potentially mobile fractions, i.e. metals of fractions I and II, was lower compared to the non-mobile fractions III and IV.

The aim of this paper is to assess the effects of different doses of sewage sludge compost mixed with wheat straw on heavy metal content in Italian ryegrass and in soil. A two year experiment with the Italian ryegrass was set up in autumn 2012. The experimental design consisted of a control plot, a plot with NPK fertiliser and three plots with three different doses of municipal sewage sludge compost (5, 10 and 15 Mg of fresh matter·ha-1). Those different compost doses contained the amounts of Nitrogen equivalent to 60, 120 and 180 kg·N.ha-1. The two lower doses of compost were supplemented with nitrogen fertiliser so that the amount of this chemical element introduced to the soil of all plots with compost stood at 180 kg·ha-1. During 2013 and 2014 seasons the grass was cut three times a year after about a 30-day growing period. After dry mineralisation, the content of Zn, Cu, Ni, Pb and Cd in the plant samples was measured with the ICP-AES method. The fertilisers applied significantly diversified the content of chemical elements in the grass and in the soil. The highest dose of compost resulted in the highest concentration of Zn, Cu and Cd in the grass while the highest concentration of Ni and Pb was in the soil and the grass from the plot where the mid dose of compost had been applied. Cadmium concentration in the soil was the highest in the plot where the mid dose was applied. The experiment proved that compost made with sewage sludge and wheat straw is beneficial for plants.

The article considers the results pertaining to the influence of solonetzic soils chemical amelioration on the presence and redistribution of heavy metals and radionuclides in meter profile of soils. Meliorative procedures were carried out 45 years ago. Phosphogypsum has been used as chemical ameliorant up to 90-s on the solonetzic soils of Tyumen region. It is a by-product of phosphates production. The objective aimed at revealing possible negative consequences connected with the introduction of the chemical elements associated with phosphogypsum. The studies showed that phosphogypsum introduction contributes to some increase in the content of active forms of heavy metals (zinc Zn, copper Cu, cadmium Cd and lead Pb) in soil. However, critical values are achieved only by active lead Pb. The evaluation of radioactive state of meadow crusted solonetzic soils after carrying out of meliorative procedures (for the same period) on the content of isotopes of thorium-232 (Th-232), calium-40 (K-40), radium-226 (Ra-226), caesium-137 (Cs-137) and strontium-90 (Sr-90) indicated that redistribution of radionuclides after chemical melioration does not cause a negative change of radiation background. Vibrations in the soil profile are connected with various initial concentration in rock formations or weathering detritus. Specific effective activity (Аeff ≤ 370 Bq/kg) testifies to the soils being studied and absence of their additional introduction with introduced doses of phosphogypsum.

Opis:
The article reports the conducted analyses of certain chemical parameters characterising the sediments of Poland’s Besko Reservoir. Specifically, determinations concerned the pH value, percentage organic matter (OM), total organic carbon (TOC), total nitrogen (TN), carbonates (CO32-), total phosphorus (TP) and its fractions, as well as heavy metals (Fe, Al, Cr, Cu, Ni, Cd, Zn, Mn). The sediments have a slight alkaline reaction, with pH values correlating positively with the high content of carbonates. The sediments have low organic matter content, while organic carbon accounts for about 30% of OM. The values for the C:N ratio point to an allochthonous origin for organic matter. The analysis of phosphorus fractionation showed that inorganic phosphorus (IP) is predominant at every research station. The lowest percentage for a fraction was in turn obtained for NAIP. This testifies to a slight anthropogenic impact of the catchment area. The sediments can be classified as of the 2nd purity class (according to PIG), due to their highest concentration of chromium. According to Müller’s classification, the sediments can be classified as purity class 3 (i.e. with moderate contamination). The values noted for the EF coefficient confirm a very strong enrichment by chromium ions. In addition, chromium, copper, nickel and cadmium have a negative effect on aquatic organisms. The results show that the sediments can be used for example in building and maintaining hydraulic structures.

Opis:
The development of industry, agriculture, and transport contributes to an increased environmental pollution by heavy metals. The aim of the study was preliminary assessment of the contents of selected metals (lead, cobalt, copper, chromium, cadmium and nickel) in the sediments of Bug river. The study comprised part of the river flowing through Poland. It was found that the Bug river sediments are not contaminated in respect to the content of tested metals. Based on the analysis of the study results, these metals can be lined up in the following order: Cr > Pb > Cu > Ni > Co > Cd. Statistical analysis showed that copper and chromium occur in Bug river sediments in forms bindings with organic matter in majority of cases. The granulometric analysis of sediments from Bug river revealed the largest percentage of two fractions: 1.0–0.2 mm with average of 47.7 ± 19.77% and 0.2–0.1 mm with average of 20.6 ± 7.7%. These are the dominant fractions with the accumulation of metals in river sediments, which has been confirmed by statistical analysis.

Opis:
This study defined the heavy metal concentration in rice, a commonly consumed staple food in Indonesia that is domestically produced and also imported from other countries due to its high demand. A total of six rice samples, comprising of four domestic and two foreign were randomly taken from Semarang stores and analyzed using the Atomic Absorbance Spectrometer (AAS). The laboratory results revealed that three varieties of rice, two from Indonesia (MW and PW; 0.561 and 0.456 mg/kg, each), and one from the United States (B; 0.307 mg/kg), exceeded the Indonesian dietary standard for lead (Pb) (SNI). Furthermore, the concentration of chromium (Cr) in two rice that are imported (B, 0.241 mg/kg and J, 0.723 mg/kg) were greater than the 0.2 mg/kg threshold established by the Chinese government. However, all samples had acceptable levels of As and Hg, and none had detectable levels of Cd. In terms of pH levels, domestically produced rice had a wider range (3.88–5.78) compared to imported rice (4.96–5.68). Although locally grown and imported rice had acceptable levels of LCR, only one local rice sample and two imported rice samples exceeded the Target Hazard Quotient (THQ) as well as Hazard Index (HI) values. In conclusion, consuming heavy metals contamination rice on a regular basis poses carcinogenic as well as non-carcinogenic health risks.

Opis:
In recent years, the interest in the occurrence of heavy metals in the natural environment has been observed. The heavy metal contamination can lead to serious environmental problems. The aim of the study was to estimate the total content of heavy metals: Ni, Cu and Co, in the surface layer of the bottom sediments of the Sokołda river and its tributaries, and to determine the relationship between the grain size and scope of their metal content. Determination of metals in the bottom sediment samples was performed by means of atomic absorption spectrometry (ASA). The research on the Sokołda river and its tributaries showed low levels of Ni, Cu and Co. It was proven that the majority of studied metals were contained in the smallest clay fraction <0.02 mm. On the other hand, the least studied metals were accumulated in 1.0–0.2 mm and 0.2–0.1 mm fractions. The 1.0–0.2 mm and 0.2–0.1 mm fractions contain around 80% of the tested metal forms, while the 0.02–0.063 mm and <0.02 mm fractions – only a few percent. This speaks for the determination of metals in the 1.0–0.1 mm fraction, that contains both coarser and clay fractions, and thus most reliably reflects the actual load of pollutants carried by the sediment. Studies have shown that the main sources of pollution in the Sokołda river catchment are primarily surface runoff, and to a lesser extent, wastewater (municipal and industrial).

Opis:
It has been substantiated that the increase in the concentration of heavy metals in the environment has especially aggravated in the conditions of military operations on the territory of Ukraine. The use of woody plants for the purposes of phytoremediation is one of the most effective options for optimising the state of the environment in urban ecosystems, regardless of the nature and source of contamination by metallic elements, which is of significant relevance in the conditions of post-war environmental restoration of Ukraine. The purpose of the study is to explore the peculiarities of some heavy metals accumulation by the assimilation apparatuses of the black locust (Robinia pseudoacacia L.) plants growing in the recreational areas of the city of Dnipro in order to further optimise tree plantings with the aim of improving the environment. The content of heavy metal elements (Cu, Zn, Pb, and Cd) in the biomass of the Robinia pseudoacacia L. leaves and in the soils of Dnipro recreation areas has been determined. The intensity of the accumulation of heavy metals in the phytomass of the Robinia pseudoacacia L. represents the following sequence Zn > Cu > Pb > Cd, which demonstrates a more intense absorption and accumulation in the phytomass of the leafy fraction of Zn and Cu in the phytomass of the deciduous fraction, and less significant of Pb and Cd. With the help of geo-information systems, cartographic material has been developed. It demonstrates the concentration gradient of Pb, Cu, Cd, and Zn in the assimilation organs of the black locust plants in the city of Dnipro recreational areas. Based on the cartographic analysis, it has been proved that the general condition of the soils in the recreation areas of Dnipro is characterised by significant disproportions in the level of pollution. The maps show the existing potential of the accumulative capacity of Robinia pseudoacacia L. to deposit Pb, Cu, Cd, and Zn, which allows for additional city functional zoning by considering phytoremediation functions of the existing and planned green spaces.

The purpose of this study was to determine the total content of cadmium, lead, nickel, copper, zinc and their fractions in organic soils of Podlasie used as permanent grassland. The research material were samples taken from 30 soils of the Podlasie province in 2011-2013. The samples were taken from the determined layer to depth of 0-30 cm. Basic physicochemical properties were determined in the taken soil samples: organic carbon content, pH in 1 M KCl potentiometrically. The total content of metals after mineralization in aqua regia was determined, and cadmium fractions were determined with a modified BCR method. The measurements were conducted by means of atomic absorption spectroscopy with electrothermal atomization using Varian AA-100 spectrometer. It was found that only 2 soils can be included in the soils with first pollution degree due to the cadmium content. The content of other metals was at geochemical background level. The distribution of investigated metals in the fractions in studied organic soils was different comparing to mineral soils. Most of the analyzed elements were present in the fraction associated with organic substance, which limited their mobility, as evidenced by their low share in the available and potentially available fraction. The proportion of metals in the residual fraction was low, which is typical for organic soils. The share of studied metals in particular fractions varied depending on the sampling date, which may be related to the climatic conditions course in the study period and the treatments performed on these soils.

Using water hyacinth as a phytoremediation agent produces abundant biomass due to periodic harvesting in the system. One of the alternative uses of water hyacinth biomass can be a bio-sorbent to absorb metal contamination in the waters. This study aims to determine the quality of activated water hyacinth bio-sorbent, potentially reducing metal cadmium (Cd). The research was conducted from January to April 2022. The results showed that the parameters of water content, iodine absorption, and methylene blue in water hyacinth bio-sorbent had met the quality standard of activated carbon based on SNI No. 06-3730-1995. In contrast, the ash content still did not. In water, hyacinth stem bio-sorbents (stems + ZnCl2 and stems 300 °C + ZnCl2) obtained higher ash content (25.87 and 73.30%) than the ash content of water hyacinth root and leaf bio-sorbent with the same activation treatment. The optimum adsorption capacity (Qe) for the roots + ZnCl2 occurred at a contact time of 45 minutes which was 8.13 mg/g with an absorption efficiency (Ef) of 34.20%. For the root 300 °C + ZnCl2, the optimum adsorption capacity and absorption efficiency occurred at a contact time of 8 hours, namely 9.08 mg/g and 38.66%, respectively. The optimum adsorption capacity and absorption efficiency of the leaves + ZnCl2 occurred at a contact time of 4 hours, namely 7.63 mg/g and 32.12%, respectively. Meanwhile, at the leaves 300 °C + ZnCl2, the optimum adsorption capacity and absorption efficiency occurred at a contact time of 8 hours with a value of Qe = 11.84 mg/g and Ef = 49.35%.

Opis:
This study focused on the effect of heavy metal cobalt ions (at concentrations of 1–1000 ppm) on the development and enzymatic activity of four entomopathogenic fungi: Beauveria bassiana, Beauveria brongniartii, Isaria fumosorosea and Metarhizium robertsii, commonly used in biological plant protection. It was found that each of the tested species of fungi reacted individually to contact with the Co2+ ions at their various concentrations. Depending on the variants of the experiment carried out, there were changes in the development of the mycelia (mainly growth inhibition) and their morphological features (color and structure) in comparison to the control samples. Co2+ ions had a fungistatic effect on all fungal strains, whereas a fungicidal effect was noted at concentrations of 750 ppm and 1000 ppm against M. robertsii and I. fumosorosea, respectively. In addition, there was a discrepancy in enzymatic activity between the tested fungal species developing in the medium with varying concentrations of metal salt. The inhibitory effect of Co2+ ions on lipase production was observed in I. fumosorosea. Protease production was stimulated in B. bassiana at all Co2+ concentrations, whereas in M. robertsii this effect was noted at 1 ppm. The changing dynamics of extracellular fungal hydrolases, due to the action of Co2+ ions, may translate into the role of these microorganisms in the processes of insect pathogenesis. This work suggests that severe pollution of the environment by cobalt could be a restrictive factor for the development and pathogenicity of entomopathogenic fungi and must be taken into account for their successful application in biological plant protection.

Currently, much attention is paid to the search for the etiology of many eye diseases. It has been shown that environmental pollution with heavy metals (cadmium, lead, mercury) is of significant importance. One of these diseases is cataract, i.e. clouding of the lens of the eye. It turns out that heavy metals are deposited in the tissues of the eyes, damaging them and accelerating the disease. This work is aimed at presenting the problem of the influence of heavy metals on cataracts. The study compares the concentration of heavy metals between the control group (81 healthy volunteers) and the group of cataract patients (72 sick). Plasma was used in the research and the ICP-MS method was used.

Opis:
In this work we compared the effect of five heavy metals: Zn, Pb, Cd, Ni and Cu on phospholipid composition of the ubiquitous soil fungus Paecilomyces marquandii, originating from a strongly metal polluted area and characterized by high tolerance to these elements. Cd, Ni and Cu caused an increase in phosphatidylcholine (PC). Only Pb decreased PC content, which was accompanied by a significant rise in the phosphatidic acids (PA) level, probably due to activation of phospholipase D which hydrolyzes PC to PA. This could result in membrane fluidity disturbance, and thus affect its integrity. The assessment of propidium iodide influx showed strong disturbance of membrane integrity for Cu and Pb stressed mycelia, whereas mycelia treated with Ni were impermeable to this dye. The results obtained revealed a strong Cu and Pb toxicity involving disruption of membrane integrity. Pb action was reflected by lipid composition, whereas changes in Cu treated mycelia did not completely elucidate its harmful effect on the membrane, which was most probably caused by Cu induced lipid peroxidation. Zn did not induce quantitative changes in PC and phosphatidylethanolamine (PE) but caused changes in phospholipid lipid saturation, which appears to be important for fungus adaptation to the presence of metals. The enhanced PC content balanced by higher PC saturation can help in the maintenance of proper membrane fluidity and result in alleviating the Cd and Ni induced stress. These results will allow to clarify the mechanism of Pb toxicity and help to elucidate the cellular basis of fungal membrane adaptation to heavy metals.

Opis:
Agricultural residues rich in lignocellulosic biomass are low-cost and sustainable adsorbents widely used in water treatment. In the present research, thermodynamics, kinetics, and equilibrium of nickel(II) and lead(II) ion biosorption were studied using a corncob (Zea mays). The experiments were performed in a batch system evaluating the effect of temperature and dose of adsorbent. Langmuir and Freundlich isotherms were used to study the equilibrium. Thermodynamic and kinetic parameters were determined using kinetic models (pseudo-first order, pseudo-second order, Elovich). Biosorbent characteristics were studied by Fourier-transform infrared spectroscopy, Scanning Electron Microscopy and Energy-dispersive X-ray spectroscopy. It was found that the hydroxyl, carboxyl, and phenolic groups are the major contributors to the removal process. Besides, Pb(II) ions form micro-complexes on the surface of the biomaterial while Ni(II) ions form bonds with active centers. It was found that the highest Ni(II) removal yields were achieved at 0.02 g of adsorbent and 70°C, while the highest Pb(II) removal yields were achieved at 0.003 g and 55°C. A maximum Ni(II) adsorption capacity of 3.52 mg∙g–1 (86%) and 13.32 mg∙g–1 (94.3%) for Pb(II) was obtained in 250 and 330 min, respectively. Pseudo-first order and pseudo-second order models best fit experimental data, and Langmuir and Freundlich models well describe the isotherm of the process. Thermodynamic parameters (ΔH0, ΔG0, ΔS0) suggest that the adsorption process of both cations is exothermic, irreversible, and not spontaneous.

The investigations were carried out to determine the relation ship between Cr, Co, Cd, Cu, Zn and Pb content and glacial morphogenesis that implies the geomorphological position of out crops of Quaternary deposits. The analysis deals with parts of two glacial uplands whose relief developed during deglaciation of the Warta ice sheet and which are characterized by similar relief and lithology of surface deposits. These are the Nidzica Upland near Grzebsk and the Bielsk Plain near Bielsk Podlaski. These areas show distinct regularity in pattern of geomorphological units, proving their areal deglaciation. Melt-out depressions, side valleys, ablation covers, kame terraces and kames as well as glaciofluvial plains are observed. The typical geomorphological element is isolated morainic hills (mesas). The investigations en abled determinations of regularity in the distribution of chemical eleements in the soil environment of the geomorphological units. Among mineral sediments, clay interlayers observed within kameter race and kame deposits were the most susceptible to concentrations of heavy metals, regard less of the region and the element to be determined. Lower Cd, Cu, Co, Pb, Zn and Cr contents were as sociated with morainic mesa and ablation cover deposits. The lowest contents of heavy minerals were mea sured in glaciofluvial plain, kame and kame terrace sands. Among land forms filled with organic deposits, the high estabilities to fix Cr, Co, Cu and Zn were shown by ice-dammed basins within upland deposits (Nidzica Upland) and side valley deposits (Bielsk Plain). Peats and muds of melt-out depressions were found to be most active in retaining Cd and Pb.

These metals accumulate in neighboring soils and may pose particular health risk for railway workers or people who simply pass through the railroad tracks. Plants are able to uptake metals from soil, thus reduce soil contamination and movement of pollutants. Individual species are characterized by different accumulation efficiency. In this study fifteen species were examined for accumulation of 14 metals. Cerastium dubium accumulated the majority of metals most efficiently.

Effluents from industries contain appreciable amount of metallic cations like zinc, copper, iron, manganese, lead and cadmium. Release of heavy metal without proper treatment poses a significant threat to public health because of its persistence biomagnifications and accumulation in food chain. To reduce metal pollution problems many processes have been developed for the treatment and disposal of metal containing wastes. Certain plants have the ability to accumulate heavy metals such as Pb, Cr, Cd and Zn. At present, phytoremediation of metals may be approaching commercialization. Hence, possibility can be explored to remove heavy metal load, present even in low concentration, in waste water of paper mill effluent soil by using Croton sparsiflorus.

Many applications of probiotics have been described to date. In this paper, it is hypothesized that probiotic microorganisms can also be used to decrease the xenobiotics intake in humans. The use of probiotic bacteriae (e.g. strains of Lactobacillus sp. and Bifidobacterium sp.) and yeasts (Saccharomyces sp.) gives the opportunity for detoxification of various elements and compounds, considered as contaminants, directly in the lumen of human intestine. Some of these microorganisms are known to accumulate cesium, strontium and heavy metals to a great extent and also bind mycotoxins. Certainly, during the up-coming years, their native or genetically modified strains will be a part of treatment protocols in detoxification therapy. The utilization of probiotics, in the both therapy and nutrition of people living in the countries suffering from high food contamination, could result in the reduction of annual xenobiotic dose to be incorporated in their organisms.

The biosorption of Pb(II), Zn(II) and Ni(II) from industrial wastewater using Stenotrophomonas maltophilia and Bacillus subtilis was investigated under various experimental conditions regarding pH, metal concentration and contact time. The optimum pH values for the biosorption of the three metals were in the range 5.0-6.0, while the optimal contact time for the two bacterial species was 30 min. Experimental data was analyzed using Langmuir and Freundlich isotherms; the former had a better fit for the biosorption of Pb(II), Zn(II) and Ni(II). The maximum adsorption uptakes (qmax) of the three metals calculated from the Langmuir biosorption equation for S. maltophilia were 133.3, 47.8 and 54.3 for Pb(II), Zn(II) and Ni(II), respectively, and for B. subtilis were 166.7, 49.7 and 57.8 mg/g, respectively. B. subtilis biomass was more favorable for the biosorption of Pb (II) and Ni (II), while S. maltophilia was more useful for the biosorption of Zn (II).

Opis:
The bottom sediments of river hydroecosystems were studied for the gross content of heavy metals (K, Ti Cr, Fe, Ni, Cu, Zn, Rb, Sr and Hg). The environmental and geochemical processes of bottom-sediment formation in aqua landscapes were analyzed, allowing us to stress the need to determine the methodological basis for the correlation-regression dependence of the heavy metal accumulation processes in bottom sediments, as well as total content of organic carbon. The ranking of pairwise correlation coefficients arranged in decreasing order is: TOC:Cu (0.87) >TOC:K (0.82) >TOC: Ni (0.75) > TOC:Sr (0.73) > TOC:Fe, (0.7) >TOC:Ti (0.67) > TOC:Hg (0.63) > TOC: Cr (0.58) >TOC:Rb (0.56) > and TOC:Zn (0.51). The proposed methodological approach determines the environmental and geochemical aspects of the sedimentation processes heavy metals, while also identifying the general trends in hydroecosystems prone to the anthropogenic impact.

The objective of this study was to analyze the content of heavy metals and arsenic in soil and cereal grains as well as to evaluate the possible human risk in the central region of Peru. The soil samples of corn and barley grains were collected from seven agricultural zones and the concentrations of Cu, Fe, Pb, Zn and As were determined with the method of atomic absorption flame spectrophotometry. PERMANOVA showed that the effect of the type of crop and the sampling zone significantly influence the concentrations of heavy metals and As in soil and corn and barley grains (p < 0.05). PCA for heavy metals and As in soil and grain samples of the cereals studied showed that the first two main components represented 81.03% and 94.77% of the total variance, respectively. Hazard Quotient (HQ) for ingestion was the most significant. The HQ values of Pb and As in crop soils indicated that detrimental health effects are unlikely (HQ < 1). The soil hazard index (HI) values of both crops did not exceed the threshold value of 1 (HI < 1). The carcinogenic risk level (CR) of As from ingestion of corn and barley crop soils contaminated by As was higher in children than in farmers and adults. The bioconcentration factor (BCF) of As was higher in barley grains than in corn grains. The THQ of As exceeded the target value of 1 in 100% of the barley and corn sampling sites. The RC of As in grains exceeded the acceptable risk level of 10–6 in all sampling zones.

Opis:
The heavy metal pollution in seawater and sediment can damage mangrove ecosystems and accumulate in mudskipper (Periophthalmus spp.) that lives in mangrove forests. The accumulation of heavy metal in mudskipper can affect the structure of its gill tissue, liver, and muscles. This research aims at (1) analyzing the levels of lead, cadmium and cuprum heavy metals in mudskipper, sediment, and seawater and (2) analyzing the damage to the gill, liver, and muscle tissue of mudskipper due to the exposure to heavy metals. The mudskipper samples were collected from the mangrove forests of Poka, Waai, and Rutong from May to June in 2019. The heavy metal analysis was conducted using the AAS method, while the gill, liver and muscle tissue staining was carried out with the HE (Hematoxylin Eosin) staining method with 40x magnification. The data were analyzed using descriptive analysis and correlational analysis. The results of the analysis showed that based on the mangrove locations, the order of Pb and Cu accumulation in mudskipper was Rutong> Poka> Waai; while the order of the Cd accumulation was Rutong> Waai> Poka. The changes in the gill tissue structure due to the exposure to heavy metals were in the form of teleangiectasia, secondary lamellar edema, hyperplasia, epithelial desquamation, clubbing, and primary lamellar edema. The changes in the liver tissue structure due to the exposure to heavy metals involved hemorrhage and fat degeneration. The changes in the muscle tissue structure due to the exposure to heavy metals include changes in muscle fibers, edema, and necrosis. The highest accumulation of Pb and Cd was found in gills and muscles from seawater, while low level of heavy metal Cu was found in the liver.

The aim of the research was to demonstrate differences in the content of trace elements (U, Th, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, Ge, As, Se, Cd, Mo, Hg, Pb, W, Ba) in coal mined in Poland and coal imported from Russia, which are widely available on the market. Ecophile, cube and nut were selected for the research. Among them 3 come from Russia and 3 from Poland. The samples were mineralized and the heavy metal content was determined with the use of mass spectrometry with excitation in induced plasma. The research allowed us to conclude that the same carbon grades showed completely different metal contents and depended on the place of origin. The greatest amount of trace elements was found to be found in ecophysics from Poland (durin). Relatively large contamination with trace elements was also found in Polish peach (window) and in Russian walnut. A relatively high content of uranium was found in three samples, including the ecophyses. When burning coal, even of high quality, we expose the environment to the burden of trace elements, including radioactive elements present in their composition. Heavy metals from coal combustion constantly accumulate in the environment and so far no standards have been established for their content in this fuel.

Opis:
The main purpose of this work was to determine the degree of negative impact of heavy metals accumulated in the water sediments to aquatic organisms. Samples of sediments were collected in winter 2013, from 4 layers of sediment (0-5, 5-10, 10-20 and 20-30 cm) at three points along the water reservoir. Sediments were prepared for analysis in accordance with the procedures applied in soil science. The analysis was carried out for the fraction with a particle diameter less than 1 mm. The total content of such elements as Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn, was determined by atomic absorption spectrometry (using the Thermo Scientific iCE 3000 series spectrometer) after digestion in a mixture (5:1) of concentrated acid HNO3 (65 %) and HClO4 (60%). The total Hg content was obtained by using the AMA 254 analyzer. Only the lead content in the analyzed samples of bottom sediments exceeded the contamination value given by polish law (the Regulation of the Minister of Environment). According to the classification of PGI samples of sediments are classified mainly as medium polluted sediments (Class II), with the exception of zinc and lead concentrations (Class III). Due to the value of the indicator of sediments ecological risk (Er) for cadmium, the examined sediments from small water reservoirs no. 1 and 2 should be classified as deposits with a higher rate of environmental contamination risk. The sediments from small water reservoirs no. 3 and 4 belong to the class of a much higher index of contamination risk. On the basis of the PER indicator (a degree of potential envi ronmental risk) the sediments from small water reservoirs located within the area of organic farming can be classified as contaminated by heavy metals to a moderate degree. On the other hand, the analyzed sediments of small water reservoirs no. 3 and 4 were classified as deposits with a severe degree of heavy metal contamination. On the basis of the LAW classification one can say that the bottom sediments of examined ponds were classified into different classes depending on the analyzed chemical element.

Opis:
Heavy metal is a type of metal that has a high density and high toxicity when consumed by living things, especially humans. To prevent the impact of environmental pollution, optimal handling of wastewater containing heavy metals is required, including the wastewater from laboratories. This research aimed to study the effect of pH, catalyst dose, and irradiation time on the reduction of Copper (Cu), Iron (Fe), and Lead (Pb) heavy metals and their application to laboratory wastewater treatment. Among the Advanced Oxidation Processes (AOPs) methods, photocatalysis was chosen to reduce the level of Cu, Fe, and Pb heavy metals where zinc oxide (ZnO) is used as a photocatalyst and the sunlight as a light source. To determine the effect of pH, catalyst dose, and time on the reduction of heavy metal levels, firstly, this research used the synthetic wastewater containing Cu, Fe, or Pb heavy metals. On the basis of the experimental results, it is concluded that the pH value, catalyst dose, and time affect the photocatalytic process, decreasing the levels of Cu, Fe, and Pb metals. The optimum pH value obtained for Cu was at pH 7–8, for Fe it was at pH 6, and for Pb it was at pH 8; in turn, the metal removal percentages were 99.46, 99.91, and 99.70%, respectively. In the photocatalysis of synthetic wastewater, high removal percentage of more than 99% was achieved by using 0.1 g/L catalyst. The optimum decrease of metals occurred in the first 15 minutes of solar irradiation where the removal percentage was close to 100%. In this study, the application of ZnO photocatalyst under solar irradiation can reduce the heavy metals content in the laboratory wastewater by almost 100%, which meets the environmental quality standard for Cu, Fe, and Pb.

The toxic heavy metals, as non-biodegradable pollutants, have become a serious threat to aquatic environment. This study aimed to assess the efficiency of the low cost, available and environment-friendly peanut shell as an effective adsorbent for the removal of Zn, Pb and Cd from wastewater. The peanut shell was prepared by carbonization by pyrolysis process at 550 °C, activated with 7M potassium hydroxide(KOH) at 750 °C, and then characterized by using Scanning Electron Microscopy (SEM), and Fourier Transform Infrared spectroscopy (FTIR), X-ray diffraction (XRD) and Brunauer-Emmett-Teller (BET) surface area analysis. The optimum conditions for metal ions adsorption were investigated as a function of various parameters. The optimum conditions included: pH of 6, initial metal concentrations of 20 mg/l for Pb and Zn as well as 40 mg/l for Cd, adsorbent mass of 2 g, optimum temperature of 45 °C and the preferable contact time of 60 min. The removal percent for the studied metal ions exceeded 98%. The adsorption isotherm showed that the Langmuir model was the best fitted model for the metal ions adsorption onto activated peanut shell surface, and the kinetic of adsorption followed the pseudo-first order model. The obtained results showed that the KOH-activated peanut shell possess higher adsorption efficiency for the removal of the studied metal ions from wastewater.

Opis:
Wykorzystanie osadów ściekowych do gruntów na cele rolne i nierolne ma pewne ograniczenia ze względu na zawartość metali ciężkich i skażeń sanitarnych. Metale ciężkie w glebie ulegają procesom mogącym powodować zmiany stężeń i form chemicznych, dlatego też ich ogólna zawartość nie zawsze jest odpowiednim wskaźnikiem ich bioprzyswajalności. Znajomość mechanizmów immobilizacji chemicznych form pierwiastków pozwala zredukować zagrożenie dla środowiska. W tej pracy przedstawiono metody ekstrakcji sekwencyjnej, które pozwalają określić względny udział poszczególnych frakcji danego pierwiastka i ocenić ich ekoszkodliwość. Posługując się analizą sekwencyjną, można określić ilość danego pierwiastka, który może zostać włączony do łańcucha: osad - gleba - roślina - człowiek. Omówiono istniejące metody ekstrakcji sekwencyjnej, przedstawiono rodzaje użytych ekstrahentów, dokonano opisu warunków prowadzonych procesów i oceny zastosowanych metod ekstrakcyjnych. Przeanalizowano wpływ sposobów ekstrakcji sekwencyjnej na rozdział i mobilność metali w osadach ściekowych. Zaprezentowano metodę chemicznej ekstrakcji sekwencyjnej do oceny jakościowej i ilościowej zawartości metali w poszczególnych frakcjach. Ponadto, przedstawiono porównania i wyniki, mające zobrazować skuteczność ekstrakcji sekwencyjnej we wskazaniu realnych zagrożeń chemicznych. Zaobserwowano, iż do form najbardziej mobilnych, a więc łatwo przechodzących do roztworu, należą metale występujące w połączeniach rozpuszczalnych w wodzie, wymienialne oraz metale związane z węglanami (frakcje 1 i 2). Metale związane z tlenkami żelaza i manganu oraz materią organiczną są również łatwo dostępne, jednak ich uwalnianie zachodzi znacznie wolniej (frakcje 3 i 4). Za unieruchomione metale uznano ich formy, które gromadzą się w pozostałości nierozpuszczalnej w stężonych kwasach. Metale tej frakcji są chemicznie stabilne i biologicznie nieaktywne. Wskazano, iż analiza form chemicznych metali powstałych podczas ekstrakcji zależała od: ilości uzyskanych frakcji, rodzaju i stężenia reagentów, warunków prowadzenia ekstrakcji. Na podstawie uzyskanych przez różnych autorów wyników stwierdzono, że udział określonych form chemicznych pierwiastków uzależniony jest od zastosowanej procedury. Dobór odpowiedniej metody ekstrakcji metali z osadów ściekowych powinien być uzależniony od celu prowadzonej analizy specjacyjnej i analizowanych form chemicznych. Ponadto stwierdzono, iż metody, zarówno zaproponowane przez Tessiera, jak również BCR (Commission of European Communities Bureau of Reference), są wystarczająco powtarzalne i odtwarzalne, aby mogły być stosowane do frakcjonowania metali z osadów ściekowych.
Usage of sewage sludge for agricultural and non-agricultural purposes is limited because of contents of heavy metal particles and sanitary contamination. Heavy metals in soil undergo processes that could cause changes of concentrations and chemical forms, and therefore their overall contents is not always the right indicator of their bioassimilation. Knowledge of immobilization mechanisms related to chemical forms of elements helps to reduce environmental risk. In present paper, sequential extraction methods were presented. These methods allow to determine relative share of each fraction of a certain element, and assess their harmfulness to environment. Sequential analysis can be used to determine concentration of a certain element, which could join to the chain: “sludge - soil - plant - human”. Known methods of sequential extraction have been discussed, types of extractors and description of process parameters have been presented, extraction methods have been valuated. Influence of used extraction method on separation and mobility of metals in sewage sludge has been analyzed. Chemical sequential extraction has been presented as the method for quantitative and qualitative estimation of heavy metals contents in each fraction. In addition, several comparisons and test results have been presented, in order to confirm effectiveness of sequential extraction as the right method to indicate real chemical hazards. It was observed, that metals in easily water-soluble forms, exchangeable metals or bound with carbonates (fraction 1 and 2) are most mobile forms, means easily migrating into the solution. Metals bound with iron oxides, manganese oxides and also bound with organic matter are also easily available, but they are released much slower (fraction 3 and 4). Metals in remaining part, soluble in concentrated acids, are considered as immobile form. Metals in this fraction are chemically stable and biologically inactive. It was indicated, that analysis of chemical forms of metals created during extraction depended on number of fractions, type and concentration of reagents and extraction process parameters. On the basis of results given by various authors, it was concluded that share of certain chemical forms of elements depends on the procedure used for the analysis. Choosing the method of extraction of metals from sewage sludge should depend on the purpose of spacing analysis and types of chemical forms that have to be analyzed. Additionally it was stated, that methods proposed by Tessier and BCR (Commission of European Communities Bureau of Reference) are repeatable and reproducible enough, to be used for fractionation of metals from sewage sludge.

The pollution of urban soil with heavy metals caused by traffic activity is increasingly becoming a great threat to human health and environmental quality. This paper presents results of research of lead (Pb) and cadmium (Cd) distribution in land on playgrounds situated near busy streets in Cracow (Poland). Samples of sand and soil were collected from the most top layer (0–10 cm). Concentrations of examined metals are: Pb from 6.80 to 54.04 mg/kg and Cd from 1.60 to 2.61 mg/kg, respectively. The highest concentrations were found in sampling points near the busiest roads, and are particularly visible in the case of lead concentration in soil samples. For sand samples, metal concentrations are much lower. Although the results have not determined a high degree of soil’s contamination, they indicate the problem of the children’s exposure to toxic metals. Urban soil should be monitored particularly in such special places as playgrounds.

The present research work deals with the quantification of toxic heavy metals in the water samples collected from sea water in Międzyzdroje. While the annual average concentration of Cadmium was calculated as 0.44 ppm in 2008 of the year and 0.46 ppm in 2009 of the year. The values obtained were found to be below the permissible limit of 2.0 ppm set for inland surface water. While the annual average concentration of Chromium was calculated as 2.67 ppm in 2008 of the year and 2.64 ppm in 2009 of the year. Which was very much above the permissible limit of 0.1 ppm set for inland surface water. The observed annual average concentration of Copper in the water was 0.08 ppm in 2008 of the year and 0.05 ppm in 2009 of the year, which was below the permissible limit of 3.0 ppm set for inland surface water. While the annual average concentration of Mercury was calculated as 0.05 ppm in 2008 of the year and 0.05 ppm in 2009 of the year, which was very much above the maximum limit of 0.01 ppm set for inland surface water. The annual average concentration of Nickel in the water samples was observed to be 2.47 ppm in 2008 of the year and 2.70 ppm in 2009 of the year, which is close to the limit of 3.0 ppm set for inland surface water. The annual average concentration of Lead in the water samples was observed to be 0.06 ppm in 2008 of the year and 0.05 ppm in 2009 of the year, which is above the permissible limit of 0.1 ppm set for inland surface water. The results of the present investigation indicate that the annual average concentration of Zinc in water samples was 3.45 ppm in 2008 of the year and 3.73 ppm in 2009 of the year, which is above the permissible limit of 5.0 ppm set for inland surface water.

Opis:
Research addresses the issue of assessing the possibility of using birch and willow trees in phytoremediation of acidic waste settlers. In order to determine the suitability of these trees to bio-accumulate metals it was crucial to first characterized the physico-chemical parameters of the waste. Both waste and leaves samples were analyzed with respect to heavy metals concentration using microwave digestion (cone. HNO3) procedure followed by AAS analyzes. Moreover, the mobility of contaminants from waste was studied using aqueous leaching test as well as sequential extraction procedures. Investigated waste is very inhomogeneous and is characterized with diversity of pH values within sampling points (2.9-7.0) as well as with high concentration of SO42 anions (1203-1301 mg/dm3), Fe (11-19%) and Zn (64-172 mg/kg). Ability to accumulate metals in birch and willow leaves is high. In birch leaves Zn was accumulated up to toxic level of 431 mg/kg, Mn up to 790 mg/kg, Cu up to 9 mg/kg, Pb up to 21 mg/kg. In willow leaves Zn concentration were found to be even higher and reached 679 mg/kg. Concentrations of remaining metals in willow leaves were as follows: Mn up to 173 mg/kg, Cu up to 17 mg/kg and Pb up to 10 mg/kg. Research results confirmed that both birch and willow trees growing on settlers have high tolerance to the adverse living conditions caused by metal stress and low pH of the foundation.

Opis:
The presence of the single metals (Cd, Pb, Cu, Zn) induces ROS (reactive oxygen species) production and causes oxidative stress in plants. While applied in two-element combinations, trace metals impact organisms in a more complex way. To assess the resultant effect we treated the pea grown hydroponically with the trace metals in variants: CuPb, CuCd, CuZn, PbCd, ZnPb, ZnCd in concentrations of 25 µM for each metal ion. Abiotic stress inhibited root elongation growth, decreased biomass production, induced changes in root colour and morphology. It changed rate of ROS production, malondialdehyde content, increased activity and altered gene expression of defence enzymes (superoxide dysmutase, catalase, ascorbate peroxidase, glutathione reductase, γ-glutamylcysteine synthetase).

Opis:
Same as in many parts of the world, many edible weeds belonging to different families that have not been cultured in Turkey are traditionally used in the making of many foods. In this study, minerals and nutrients of six edible wild plant species belonging to the Liliaceae family, which are currently used in the production of herby cheese in the Eastern Anatolia region of Turkey, were determined. The determination of these macro- and micro-minerals was performed on ICP-AES and UV Visible spectrophotometers. As a result of the study, major differences were discovered between these plant species in terms of the mineral content (Na, Mg, K, s, Ca, P, Fr, Mn, Cu, Zn, Cr, and Co) and nutrient properties (total ash, crude fibre, pH, N, and crude protein). Except for the Allium schoenoprasum species, all plant samples were found to be rich in many important minerals, such as Fe, Cu, Ca, K, Mn, and Zn, which are known to be vital for human health. The concentrations of these minerals and a few heavy metals in plant samples were found in the following ranges: 17.25 - 25.47 mg kg-1 for copper, 18.45 - 34.14 mg kg-1 for zinc, 33.42 - 98.42 mg kg-1 for manganese, 0.12 - 0.54 mg kg-1 for chromium, 0.31 - 1.61 mg kg-1 cobalt. Many significant correlations were found among the parameters analysed. The study presents essential results on the availability of some vital minerals that could be useful or harmful to consumers, in order to provide dietary information for designing value-added foods.

Opis:
Heavy metals determination in manures provides beneficial information to predict the availability and the potential contamination of environment. Therefore, a study was carried out to investigate heavy metals changes in livestock manure during a co-composting process. The metals were stepwise fractionated into exchangeable, adsorbed, organically bound, carbonate precipitated and residual forms by extracting with 0.5M KNO3, de-ionized water, 0.5M NaOH, 0.05M Na2EDTA and 4M HNO3, respectively. During the extraction process, the amount of metals remained highly dependent on an extraction method and stage of manure composting. Extractions released heavy metals contents in the final composted manure as Zn > Cu > Pb > Cr > Ni > Cd. Irrespective of the days of composting, extracting agents differed in the order HNO3 > Na2EDTA > NaOH > KNO3 > H2O for all heavy metals. Higher concentrations of heavy metals were observed during the early stages of composting. Conversely, there was a progressive increase in the concentrations of K, Ca and Mg during composting of manure. Total C in the manure reduced with composting days.

Therefore the carried out study aimed at determination of the effect of high-calcium brown coal ash and compost being produced from municipal sewage sludge on the content and bioaccumulation of heavy metals in potato tubers, wheat grains and rapeseeds during a three-year period. Rapeseeds contained most Cd whereas wheat rains less. Potato tubers, wheat grains and rapeseeds contained more Mn, Ni and Zn in the fertilization objects with municipal sewage sludge with or without coal ash and compared to those where calcium carbonate or coal ash had been introduced into the soil at a dose corresponding to 1.5 Mg CaO · ha−1  at the beginning of this study. Differences in the Mn, Ni and Zn contents in test plants between the fertilization objects with sewage sludge of with and without addition of ash were not significant.

Opis:
A single-factor fi eld experiment was carried out at the Cultivar Evaluation Station in Szczecin-Dąbie in 2008-2010. In the experiment, the compost produced with municipal sewage sludge by the GWDA method and high-calcium brown coal ash (furnace waste) were used. The perennial energy crop was a test plant - Virginia fanpetals (Sida hermaphrodita Rusby). It results from the carried out study that Virginia fanpetals biomass contained on average the most manganese (24.7 mg?kg-1 d.m.), lead (2.50 mg?kg-1 d.m.) and zinc (50.5 mg?kg-1 d.m.) in 2008, while the most cadmium (0.33 mg?kg-1 d.m.), copper (3.78 mg?kg-1 d.m.) and nickel (2.57 mg?kg-1 d.m.) in 2010. Average cadmium, copper, manganese, nickel, lead and zinc contents in test plant biomass were higher, respectively by 14.3%, 10.0%, 7.3%, 19.3%, 29.1% and 6.9%, in the objects where municipal sewage sludge compost had been applied without and with addition of high-calcium brown coal ash when compared to those where only calcium carbonate or high-calcium brown coal ash had been introduced into the soil. The differences in cadmium, copper, manganese, nickel, lead and zinc contents in Virginia fanpetals biomass between particular experimental objects were not signifi cant. The least zinc was absorbed by the test plant biomass in the object with high-calcium brown coal ash being applied in the fi rst year of study and annually. When evaluating the dynamics of heavy metals uptake, it was found to be the lowest in the fi rst year of study (ranging from 4.40% to 11.0%). It increased in the second and the third year of study, oscillating between 29.9% and 65.7%. The degree of heavy metals accumulation in Virginia fanpetals biomass differed, depending on the fertilisation applied. The bioaccumulation factor of cadmium, copper and nickel after three study years was average, while that of manganese, lead and zinc was intense.

Opis:
The performed studies allowed determining the peculiarities of heavy metals accumulation in the sediments, as well as the nature of their distribution in the hydroecosystem Southern Bug (Ukraine). Geochemical anomalies are formed in the zones of influence of industrial and urban agglomerations. Technogenic pollutions of bottom sediments with heavy metals affects the qualitative state of the water environment and can cause cumulative toxicosis on the hydrobiont population in the zones of geochemical anomalies formation, namely in the area of influence of the Nova Odessa and Mykolaiv cities. The mechanism of the cumulative toxicosis emergence is accompanied by chronic effects of low concentrations on hydrobionts with an excess of permissible fluctuations on a regional background, which ultimately contributes to the development of intoxication.

Opis:
The paper presents the results of research on the use of sewage sludge from the municipal sewage treatment plant in Białystok for fertilization of urban lawns. To fertilize the ground two types of deposits were used: stabilized sludge after the dewatering process in the press and granular sludge after drying in the sludge dryer. Two doses of sludge were used – 5 and 10 kg/m2. Effective microorganisms (EM) were added to the test plots. Both doses of the applied sewage sludge contributed significantly to the growth of grass biomass. Aboveground biomass of the plants was significantly correlated with the concentration of Cd, Cu, Pb and Zn in the surface layer of the soil. The addition of EM to soil containing the dewatered sludge from the press reduced significantly the content of heavy metals in the soil, as opposed to the sludge in a form of granules with addition of EM, which contributed to the increase of their concentration in the soil.

The study aimed at the evaluation of the quality of bottom sediments and evaluation of potential threat to the aquatic environment. Cadmium, cobalt, chromium, copper, nickel, lead, zinc and mercury concentration in the separate layers of the sediments in the pond at Żelisławiec decreased with the depth of bottom sediments. On the other hand, the highest concentrations of the studied elements occurred in the deepest layer of sediments in the pond at Stare Czarnowo. The level of the potential ecological risk (PER) for the sediments of the Żelisławiec pond classifies them as sediments with low quality of the potential ecological risk, whereas the sediments from the pond at Stare Czarnowo are classified as moderate level of the potential ecological risk. In both ponds, the highest Igeo values were reported for zinc and lead.
