Opis:
The mean and standard deviation of pH value in the present study during the wet and dry seasons varied from 6.21±0.22 - 5.75±0.41. The mean and standard deviation of EC in the current study ranges between 219.15±12.20 - 193.30±14.81 μS/cm for wet and dry seasons which are found to be in line with the WHO standard used. The mean and standard deviation of DO for this study during the wet and dry seasons were found to be 10.03±0.58 - 6.47±0.41 (mg/L). TDS for wet and dry seasons ranges from 374.79 ±5.33 - 121.65 ±6.33 mg/L. The nitrate [9.05 ±1.08 - 8.09 ±1.57], sulphate [3.91 ±0.51 – 3.73 ±0.46] and phosphate [82.78 ±3.86 - 81.76±3.32] in this present study for wet and dry season were all found to be below the standard. The Hazard quotient via ingestion and Hazard quotient via dermal has a reduction in the order of lead > nickel > iron > manganese > copper > zinc and lead > zinc > nickel > copper > iron > manganese > cadmium, in cooperation in children and adults in wet season, correspondingly. The Hazard quotient via ingestion and Hazard quotient via dermal has a decrease in the following order of nickel > lead > manganese > copper > iron > zinc and lead >zinc > nickel > copper > manganese > iron > for both children and adults in dry season, respectively. Lead possess carcinogenic risk for the inhabitants of this area due to the value of the carcinogenic risk n wet season of 4.05E-4 in adult and 1.55E-3 in children, in dry season of 2.57E-4 in adult and 9.88E-4 in children, against the standard set by the USEPA of 10-6 – 10-4. The surface water is not suitable for drinking as seen by the high water quality index of > 300. Lead possess carcinogenic risk for the inhabitants.

Opis:
The heavy metal contamination has become a serious problem in the aquatic environment, including marine sediments. This study was aimed at analyzing the content of heavy metals in marine sediments, then assessing and evaluating the level of heavy metal contamination and its ecological risks. The sediment samples were taken using a grab sampler at six sites in the coastal waters of Mimika Regency, Indonesia. The TCLP testing method was used to determine the content of heavy metals in marine sediments. The results showed that the concentrations of Pb, Cu, Cd, and Hg in marine sediments ranged from <0.25 to 0.59 ppm, <0.02 to 0.54 ppm, <0.005 to 0.03 ppm, and < 0.0007 ppm. Only the concentrations of Cu on the Meoga and Puriri sites exceeded the quality standard in the Government Regulation of the Republic of Indonesia No. 18 year 1999. The results of the assessment of heavy metal contamination and its ecological risk potential indicate that the coastal waters of Mimika Regency are included in the category of low contamination and low ecological risks. The concentration of heavy metals in this study shows that the coastal waters of Mimika Regency are not contaminated by Pb, Cu, Cd, and Hg heavy metals.

Opis:
This article is devoted to the study of water and sediment pollution in the channel of the Neva delta. Spectrophotometry was used to determine the concentration of pollutants in water. In the chemical analysis of the precipitate, atomic absorption spectroscopy and infrared spectroscopy were used. Analysis of the hydrochemical composition and sediment of the Smolenka River showed high concentrations of heavy metals and petroleum products. At the same time, the hydrochemical composition of the Smolenka River is highly unstable, but the concentration of oil products and lead in the sediments indicates the presence of local pollution sources. Based on our findings, we are guided by the restoration of the aquatic environment.

Opis:
In 1970-2000, the state of the natural environment in many regions of Poland was unsatisfactory. This situation has been improving since the integration with the European Union, mainly owing to the reduction of emissions of sulphur and nitrogen oxides. The present study included three tree species: rowan (Sorbus aucuparia L. em. Hedl.), small-leaved lime (Tilia cordata Mill.), and aspen (Populus tremula L.). The trees grew in a pollution free environment (Huszlew) and in an urban agglomeration (Lublin). The aim of this research was to make comparative observations of the structure of leaves in relation to the content of lead, zinc, copper, nitrogen and sulphur determined in these organs. The N/S ratio in the leaves was accepted as an indicator of proper metabolic processes. Observations of leaves were made with using light microscopy and the scanning electron microscopy (SEM) technique. The content of heavy metals in leaves was determined by atomic absorption spectrometry (AAS) after dry mineralization. Total sulphur was determined by the turbidimetric method, while nitrogen by the Kjeldahl method after mineralization in sulphuric acid. When influenced by polluted air, the epidermis of the examined leaves was composed of smaller cells with higher stomatal density per unit area and had a lower number of open pores compared to the epidermis of the leaves developed in a clean environment. Among the species investigated, aspen was characterized by the highest ability to bioaccumulate heavy metals in its leaves. Among the elements determined only the Zn content exceeded the permissible limit, whereas Pb and Cu were found to occur in the range of values considered to be optimal. The dominant share of lead in suspended dust caused changes in the epidermis of leaves, which led to disorders in plant water relations.

Opis:
Four metals (Cu, Zn, Pb and Cd) were assayed in soils within the impact zone of the Miasteczko Slaskie Zinc Smelter (southern Poland). The investigated area is afforested and has been subjected for a long time to intensive deposition of metal-bearing dusts. Soil pHKCl varied broadly from very acidic (pHKCl = 3.4) to slightly alkaline (pHKCl = 7.2). Organic carbon (Corg) content fluctuated within a large range, i.e., 5.5 - 66.4 g kg-1, whereas the cation exchange capacity (CEC) was in most cases markedly low (from 1.4 to 5.9 cmol(+)kg-1), with exception for two sites (C and D) exhibiting values of 26.8 and 15.1 cmol(+)kg-1, respectively. Total Zn, Pb and Cd contents exceeded manifold their respective levels in the Earth crust (reference value - RV)) as well as those suggested as background levels for Poland (BLP). The assessment of the contamination of soils by these metals was undertaken on the basis of geoaccumulation indices (lgeo), contamination factors Cl and degrees of contamination (Cdeg). The overall metal contamination represented practically two classes: low contamination for Cu; considerable to extreme contamination (in ascending order) for Zn, Cd, and Pb. The contribution (BLP-based assessment) of each metal to the degree of contamination index varied from 2.14 % (for Cu), via 26.33% (for Zn) to quite equally for Cd and Pb, both representing 35.22% and 36.32, respectively. It is worth pointing out that copper was the sole metal to threaten the least (Figure 1) the soils of the investigated ecosystem.

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 metals are a pressing concern in terms of their pollution in aquatic ecosystems because of their persistence, environmental toxicity, bioaccumulation. Aquatic environments receive heavy metals in untreated or inadequately treated wastewater from domestic, industrial, agricultural, and navigation sources. The Doi-Cho Dem-Ben Luc Rivers play the key roles of irrigation, navigation and ecological restoration. It is crucial to ascertain the pollution status, influencing factors, ecological risks, and possible sources of heavy metals in the surface water of the Doi-Cho Dem-Ben Luc Rivers. In this study, surface water from 7 sampling sites over was collected from the Doi-Cho Dem-Ben Luc Rivers, over 7 consecutive periods from April 2019 to October 2021. Each surface sample was analyzed for 9 heavy metals including Fe, Mn, Cr, Zn, Cu, Pb, Cd, Ni, As. The sampling technique and sample treatment were done based on the Standard Methods for the Examination of Water and Wastewater. The time and space variation of heavy metal concentrations were examined to test the analysis of variance (ANOVA) and correlation among all the parameters using R statistical software. The results suggest a spatial homogeneity of heavy metals in the surface water the studied rivers. Among all nine examined heavy metals in the studied area, the concentrations of Fe (1.00 ÷ 5.06 mg/L) and Mn (0.14 ÷ 0.28 mg/L) are the highest, and the concentrations of Cr, Cd and As are the lowest that lower limit of detection. The results suggested that the mean concentrations of Fe and Mn were above the acceptable limits of the National technical regulation on surface water quality (QCVN 08-MT: 2015/BTNMT). While the concentrations of Fe, Mn, Zn, Cu, Pb, Ni do not meet the Water quality criteria for aquatic life (United State Environmental Protection Agency). Anthropogenic activities can be the main source of heavy metals in in the surface water of the Doi-Cho Dem-Ben Luc Rivers. Among the heavy metals, a significant positive correlation was observed between Fe, Mn, Zn and Ni (0.64 ÷ 0.87), whereas Cu exhibited a significant positive correlation with Ni (0.51). While Cu and Pb showed a not too strong correlation with Fe, Mn, Zn and Ni (0.25 ÷ 0.48). The distribution of heavy metals may also be influenced by properties of heavy metals and fluctuations in water flows. The results provide guidance for controlling heavry metal pollution and protectting water sources in the Doi-Cho Dem-Ben Luc Rivers.
Metale ciężkie stanowią palący problem zanieczyszczenia w ekosystemach wodnych ze względu na ich trwałość, toksyczność dla środowiska i bioakumulację. Środowiska wodne sa zasilane w metale ciężkie z nieoczyszczonych lub nieodpowiednio oczyszczonych ścieków ze źródeł domowych, przemysłowych, rolniczych i żeglugowych. Rzeki Doi-Cho Dem-Ben Luc odgrywają kluczową rolę w nawadnianiu terenów, transporcie odnym i odbudowie ekologicznej. Kluczowe znaczenie ma ustalenie stanu zanieczyszczenia, czynników wpływających, zagrożeń ekologicznych i możliwych źródeł metali ciężkich w wodach powierzchniowych rzek Doi-Cho Dem-Ben Luc. W artykule przedstawiono wyniki badania wód powierzchniowych, próbki pobrano z 7 punktów pomiarowych z rzek Doi-Cho Dem-Ben Luc przez 7 kolejnych okresów od kwietnia 2019 r. do października 2021 r. Każda próbka została przeanalizowana pod kątem zawartości 9 metali ciężkich: Fe, Mn, Cr , Zn, Cu, Pb, Cd, Ni, As. Metodyka pobierania próbek i obróbki próbek zostały opracowane w oparciu o Standardowe Metody Badania Wód i Ścieków. Zbadano zmienność w czasie i przestrzeni stężeń metali ciężkich, do analizyy wyników wykorzystano analizę wariancji (ANOVA) i korelacji między wszystkimi parametrami przy użyciu oprogramowania statystycznego. Wyniki sugerują przestrzenną jednorodność zawartości metali ciężkich w wodach powierzchniowych badanych rzek. Spośród wszystkich dziewięciu badanych metali ciężkich w badanym terenie najwyższe są stężenia Fe (1,00 ÷ 5,06 mg/L) i Mn (0,14 ÷ 0,28 mg/L), a najniższe Cr, Cd i As (wartości odpowiadające dolnej granicy wykrywalności). Wyniki wskazują, że średnie stężenia Fe i Mn były powyżej dopuszczalnych limitów, opisanych w krajowych normach dotyczących jakości wód powierzchniowych (QCVN 08-MT: 2015/BTNMT). Natomiast stężenia Fe, Mn, Zn, Cu, Pb, Ni nie spełniają kryteriów jakości wody dla organizmów wodnych (Agencja Ochrony Środowiska Stanów Zjednoczonych). Działalność antropogeniczna może być głównym źródłem metali ciężkich w wodach powierzchniowych rzek Doi-Cho Dem-Ben Luc. Wśród metali ciężkich zaobserwowano istotną dodatnią korelację między zawartością Fe, Mn, Zn i Ni (0,64 ÷ 0,87), natomiast Cu wykazywała istotną dodatnią korelację z Ni (0,51). Zawartości Cu i Pb wykazywały niezbyt silną korelację z Fe, Mn, Zn i Ni (0,25 ÷ 0,48). Na rozmieszczenie metali ciężkich mogą mieć również wpływ właściwości metali ciężkich oraz wahania przepływów wody. Wyniki dostarczają wskazówek dotyczących kontrolowania zanieczyszczenia metalami ciężkimi i ochrony źródeł wody w rzekach Doi-Cho Dem-Ben Luc.

Opis:
Storm sewage flowing down the roads are collected in roadside retention, infiltration and evaporating reservoirs. Those reservoirs are the elements of rainy sewage system and the pre-cleaning process of runoff from surface of road carring the considerable load of pollutants takes place in them. The aim of the study was to estimate the quality of rainwaters taken from retention reservoirs situated along the main-road No. 4 from Krakow to Bochnia section. Water samples were taken from the both sides of the road and Zn, Cu, Ni and Pb contents were determined. Heavy metal concentrations in rainwaters collected from retention reservoirs are not high and in no cases exceed the standards admissible for surface waters. Considerable differences in the contents of analyzed metals were assessed between individual reservoirs. Higher concentrations were determined in water from tanks situated on the southern side of the route than on the northern one. Low concentrations of heavy metals in waters in the retention reservoirs may be a result of considerable amounts of organic and mineral suspension absorbing these pollutants in the bottom sediments.
Ścieki opadowe spływające z dróg są zbierane w przydrożnych zbiornikach retencyjnych, infiltracyjnych i odparowujących, Te zbiorniki są elementami systemu kanalizacji i zachodzi w nich proces podczyszczania spływów z dróg niosących znaczny ładunek zanieczyszczeń. Celem badań była ocena jakości wód opadowych pobranych ze zbiorników retencyjnych usytuowanych wzdłuż drogi krajowej nr 4 na trasie Kraków – Bochnia. Próbki pobierano z obydwu stron drogi i oznaczono w nich zawartość Zn, Cu, Ni i Pb. Stężenie metali ciężkich w wodach opadowych pobranych ze zbiorników retencyjnych nie było duże i w żadnych przypadku nie przekroczyło wartości dopuszczalnych dla wód powierzchniowych. Stwierdzono wyraźne różnice zawartości analizowanych metali w próbkach z poszczególnych zbiorników. Wyższe zawartości metali oznaczono w wodach opadowych ze zbiorników usytuowanych po południowej stronie drogi niż po północnej stronie. Małe stężenie metali ciężkich w wodach opadowych ze zbiorników retencyjnych może być wynikiem dużej zawartości zawiesin organicznych i mineralnych absorbujących te zanieczyszczenia w osadach dennych.

Opis:
Fluvial sediments accumulated in the bottoms of river valleys downstream from large cities are characterised by higher levels of heavy metal content, which poses a threat to the environment and humans. This study presents a comprehensive assessment of the degree of pollution of four alluvial sediment profiles (80 samples), collected from the bottom of the Bystrzyca river valley downstream from Lublin, conducted with the use of five geochemical indices. Channel deposits and sediments (alluvial soils) sampled from the floodplain were analysed. The content levels of the six heavy metals under study were as follows: Cd: 10.6–291.2 mg/kg, Cr: 53.1–292.4 mg/kg, Cu: 20.4–223.1 mg/kg, Ni: 2.9–19.3, Pb: 39.3–280.3, Zn: 108.9–991.4 mg/kg. The horizontal and vertical variation of the pollution level was linked with the history of anthropogenic pressure on the one hand, and the geomorphological location of a given profile on the other. Heavy metal content in the samples did not show any correlation with grain size composition, organic matter content, and Fe and Mn content. Cadmium was the element whose concentration levels were comparable with those in alluvial sediments of rivers in industrialised areas while the indices for the other metals showed varied levels of pollution: from low to high. However, the ecological risk is high for all samples as indicated by the synthetic potential ecological risk index, which takes into account the toxicity of all the metals under study.

Opis:
To explore methods for a comprehensive assessment of the treatment effect of heavy metal pollution in the sewage sludge from China’s industrial parks, we studied the wastewater treatment plant of the Nanjing MV Industrial Park as an example. Eight common heavy metals in sewage sludge – Zinc (Zn), Copper (Cu), Lead (Pb), Mercury (Hg), Chromium (Cr), Nickel (Ni), Arsenic (As), Cadmium (Cd) were studied. The treatment effect of these containments was comprehensively assessed using the absolute niche fitness model, the relative niche model and the spatial niche fitness model. All three models showed that Pb > Cu > Ni > Hg > Cd > Cr > Zn > As in the samples. However, they produced – different numerical values – the absolute niche suitability model < the spatial niche suitability model < and the relative niche suitability model. Therefore, we concluded that special attention should be paid to the carcinogenic risk of As and Cr heavy metals to the person exposed to the sewage sludge.

Opis:
Carabid beetles are frequently used as the environment condition indicators. Main purpose of this study was to test if community structure parameters of carabids indicate the stress intensity of heavy metal contamination in the soil of temperate forests. Three geographic regions in Europe differing in both degree of accumulation of heavy metals and its quality were chosen. In Olkusz (southern Poland) the main stressor was zinc, in Głogów (western Poland) – copper and in Clydach (Wales, UK) – nickel. We found strong division between assemblages from contaminated and reference sites (fig. 2). Indicator species from pollution preferring areas in one region can avoid polluted sites in the other region (tab. 2). Species preferring contaminated soils were significantly smaller than those that avoid such ecosystems (F=5.46, p<0.05). Generalized linear model indicated that species richness and biomass decreased in each stressor gradient of contaminated forests. Mean individual biomass and mean abundance of assemblages were significantly lower along zinc gradient only. Species with broader ecological range replace habitat specialists as a response to resource unpredictability. Decreased species richness and biomass in polluted forests indicate degradation of habitat resources and forest ecosystem functioning.

Opis:
The bioaccumulation ability of radionuclides 51Cr, 54Mn, 57Co, 60Co, 65Zn, 85Sr, 109Cd, 110mAg, 113Sn, 137Cs and 241Am in two red algae species from the southern Baltic Sea – Polysiphonia fucoides and Furcellaria lumbricalis – was determined under laboratory conditions. P. fucoides demonstrated better bioaccumulative properties towards most of the investigated radionuclides. As a result, P. fucoides can be recommended as a good bioindicator of radioactive environmental pollution. The bioaccumulation of radionuclides in F. lumbricalis was studied during an extended laboratory experiment. The initial extensive uptake of radioisotopes was followed by the rapid removal of cations; in general, concentrations tended to decrease with time. 137Cs displayed a different behaviour, its concentration in the algae increasing over time mainly due to its large ion radius; this is a factor that could be responsible for the stronger mechanical and chemical bonding of Cs+ and that could hamper the movement of ions in both directions.

Opis:
The aim of the study was to assess air pollution with heavy metals in Warsaw, on the basis of the concentrations of selected elements in moss samples. The active biomonitoring method (moss-bag technique) was applied using two moss species Pleurozium schreberi and Sphagnum palustre. Moss samples were collected in the Kampinos National Park, and the prepared moss bags were distributed and exposed on seven sites in Warsaw. The analysis of metals accumulated in mosses was performed twice in 2020, after two (August-September) and four months (August-November) of exposure. The concentrations of seven heavy metals (Cr, Cu, Pb, Ni, Fe, Cd and Zn) in the mosses were determined, using an Inductively Coupled Plasma Optical Emission Spectrometer (ICP OES). Our results showed a clear dependence of heavy metal accumulation in the mosses on the location of the exposition site and the exposure period. Both species of mosses were found to accumulate the most metals in the vicinity of pollutant emitters, such as the ArcelorMittal Warsaw smelter, exit roads or roads in the city with heavy traffic, petrol stations, or construction works. After 4 months of exposure, in both moss species, the highest increases in the concentrations were found for four elements: Cr, Pb, Ni and Cd.  Higher concentrations of some heavy metals in the mosses in 2020, as compared to previous studies, indicate a negative influence of progressing urbanisation on air pollution in Warsaw.
Celem przeprowadzonych badań była ocena zanieczyszczenia powietrza metalami ciężkimi w Warszawie na podstawie przyrostów stężeń wybranych pierwiastków w tkankach mchów. Zastosowano metodę biomonitoringu aktywnego (moss-bag technique) wykorzystując dwa gatunki mchów Pleurozium schreberi (rokietnik pospolity) oraz Sphagnum palustre (torfowiec błotny). Próbki mchów pobrano w Kampinoskim Parku Narodowym, a przygotowane z nich pakieciki wyeksponowano na siedmiu stanowiskach na terenie Warszawy. Analizę metali zakumulowanych w mchach wykonano dwukrotnie w 2020 roku, po dwóch (sierpień-wrzesień) i czterech miesiącach (sierpień-listopad) ekspozycji. Zawartość metali ciężkich (Cr, Cu, Pb, Ni, Fe, Cd and Zn) w mchach oznaczono stosując technikę atomowej spektrometrii emisyjnej ze wzbudzeniem w plazmie indukowanej (ICP OES). Stwierdzono wyraźną zależność kumulacji metali ciężkich w mchach od lokalizacji stanowiska oraz terminu ekspozycji. Oba gatunki mchów kumulowały najwięcej metali w pobliżu emitorów zanieczyszczeń takich jak: huta ArcelorMittal Warszawa, drogi wylotowe lub drogi w mieście o dużym natężeniu ruchu, stacje paliw czy prace budowlane. Po 4 miesiącach ekspozycji, u obu gatunków mchów, największe przyrosty stężeń stwierdzono dla czterech pierwiastków: Cr, Pb, Ni i Cd. Wyższe koncentracje niektórych metali ciężkich w mchach w 2020 roku, w porównaniu z wcześniejszymi badaniami, wskazują na negatywny wpływ postępującej urbanizacji na zanieczyszczenie powietrza w Warszawie.

Opis:
This study was based on tuber samples from the field experiment in 1996-1998 on weak loamy sand soil in a system of randomised sub-blocks. The experimental factors were: ways of nursery and varieties (Swojecka, Kulista Czerwona IHAR, Kulista Biała IHAR). Herbicide application elevated both cadmium and nickel contents in Helianthus tubers as compared to control. Tubers of Swojecka Czerwona cv. were characterised by the lowest accumulation of cadmium and nickel, those of Kulista Czerwona IHAR cv. by the highest content of nickel, and those of Kulista Biała IHAR by the highest level of cadmium.
