    Opis:
    Heavy metal pollutants in the leachate of waste landfill are a potential threat to the environment. In this study, the feasibility of using municipal sewage sludge as barrier material for the containment of heavy metal pollutants from solid waste landfills was evaluated by compaction test and hydraulic conductivity test concerning compaction property, impermeability and heavy metal retardation. Results of the compaction test showed that the maximum dry density of 0.79 g·cm−3 was achieved at the optimum water content of about 60%. The hydraulic conductivities of compacted sewage sludge permeated with synthetic heavy metal solutions were in the range of 1.3×10−8 – 6.2×10−9 cm·s−1, less than 1.0 ×10−−7cm·s−1 recommended by regulations for barrier materials. Chemical analyses on the effluent from the hydraulic conductivity tests indicated that the two target heavy metals, Zn and Cd in the permeants were all retarded by compacted sewage sludge, which might be attributed to the precipitation and adsorption of heavy metal ions. The results of this study suggest that specially prepared material from sewage sludge could be used as a barrier for waste landfills for its low permeability and strong retardation to heavy metal pollutants.

    heavy metal pollution
    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:
    Miedwie Lake is the biggest post-glacial lake of the West-Pomeranian Voievodship. At the same time it is the fifth of the largest lakes in Poland. Miedwie Lake is situated centrally between three big agglomerations, i.e. Szczecin, Stargard Szczecinski and Pyrzyce. Miedwie Lake has been since 1976, the potable water source for the City of Szczecin. The reservoir is used not only for municipal purposes, but also for fishing, tourist and recreation purposes. Unfortunately, heavy metal pollution is an ever-increasing problem. These toxic heavy metals on entering into the aquatic environment are adsorbed onto particulate matter, although they can form free metal ions and soluble complexes that are available for uptake by biological organisms. Many of these metals tend to remain in the ecosystem and eventually move from one compartment to the other within the food chain. The increase in residue levels of heavy metal content in water, sediments and biota has resulted in decreased productivity and increase in exposure of humans to harmful substances. Food chain contamination by heavy metals has become a burning issue in recent years because of their potential accumulation in biosystems through contaminated water, soil, sediment and air. The present research work deals with the quantification of toxic heavy metals in the water samples collected from Miedwie Lake (North-West Poland).

    Opis:
    The objective of this research was to examine the influence of Cd (0, 10, 20, 40 mg Cd·dm⁻³) and Pb (0, 10, 100, 200 mg Pb·dm⁻³) in growing substrate and mycorrhizal colonization of root system on growth, flowering, Cd and Pb accumulation in scarlet sage shoots. Both Cd and Pb had a negative effect on mycorrhizal colonization of scarlet sage roots. The effect of Cd and Pb on the growth of scarlet sage was negligible. Cd at 40 mg·dm⁻³ lowered the number of inflorescences and caused slight chlorosis of the lowermost leaves. Pb at 200 mg·dm⁻³ caused drying of the lowermost leaves. Both heavy metals accelerated flowering of non-mycorrhizal plants, independently of the concentration in growing media. Cd and Pb contents in scarlet sage shoots increased with the increasing content of these heavy metals in growing substrate in both non-mycorrhizal and mycorrhizal plants. Mycorrhization decreased the growth of scarlet sage and increased the accumulation of Cd and Pb in shoots of plants grown in media strongly polluted with heavy metals.
    Badania miały na celu określenie wpływu zawartości kadmu (0, 10, 20, 40 mg Cd·dm⁻³) i ołowiu (0, 10, 100, 200 mg Pb·dm⁻³) w podłożu oraz mikoryzy arbuskulamej na wzrost, kwitnienie i akumulację Cd i Pb w pędach szałwii lśniącej. Zarówno Cd jak i Pb wpływały ujemnie na kolonizację korzeni przez grzyby tworzące mikoryzę arbuskularną. Wpływ obu metali ciężkich na wzrost szałwii był niewielki. Cd w stężeniu 40 mg·dm⁻³ obniżał liczbę kwiatostanów i powodował lekką chlorozę liści dolnych, a Pb w stężeniu 200 mg·dm⁻³ zasychanie liści dolnych. Oba metale ciężkie przyspieszały kwitnienie roślin nie poddanych mikoryzacji, niezależnie od stężenia w podłożu. Zawartości Cd i Pb w pędach szałwii lśniącej wzrastały wraz ze wzrostem zawartości tych pierwiastków w podłożu, zarówno u roślin nie zmikoryzowanych jak i zmikoryzowanych. Mikoryzacja wpływała ujemnie na wzrost szałwii oraz zwiększała akumulację Cd i Pb w pędach roślin rosnących w podłożach silnie zanieczyszczonych tymi pierwiastkami.

    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.

    Miliolid (calcareous imperforated test) foraminifera have large diffusion all over the world in a wide range of marine environments, but their distributional pattern in relation to heavy metal pollution is not clearly understood yet. The aim of this study was to better understand the biological response of the miliolid species Pseudotriloculina rotunda to experimental chronic exposure at several zinc concentrations. The duration of the experiment was 10 weeks, and six different concentrations of zinc were tested between 0 and 100 mg/L. Increasing zinc concentrations led to increasing delay or to complete cease of the new chambers’ construction, with consequences on growth rates and affected vitality and biomass variations at medium to high concentrations. Moreover, our results showed that, even at high concentrations, zinc did not cause macroscopic test deformities due to anomalous arrangements of chambers.

The experimental plots were sown with two lawn grass mixtures: Eko and Roadside, and three doses of sewage sludge 0.0 (control), 7.5 kg/m2 and 15.0 kg/m2 were used. The calculated bioconcentration factor made possible to determine the mobility of the various metals from the soil solution to the aerial parts of plants. The obtained results showed that the plants absorbed Cd, Zn, Cu easier than Pb and Ni suggesting a high mobility, in particular of Cd, Zn, Cu, and reflects the easiness extraction of those metals by plants. Significant correlations between concentrations of metals in soil and grass were observed, nickel in soil was significantly correlated with Cd, Zn and Cu in plants, while the Zn content in soil with the level of Cu in plants.

    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:
    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:
    A model for estimating the precipitation of Cd-, Pb- and As-sulphide in soils at various pH is presented. pH influences not only the solubility of heavy metal-sulphides but also on the distribution of the S atom among sulphide (S²⁻, SH⁻, H₂S) and sulphate (SO₄²⁻) species by the redox potential of the soil solution. The model, based on the Nerst-equation. considers the equilibrium of protolitic processes and complex ion formation. In order to test the model, a long term field experiment polluted with different levels of toxic heavy metals on Hungarian typical soils was performed. Coarse textured soils were treated with Cd. Pb and As salts at pH = 6.8 and 8 and after 6 months and 2 years the heavy metal precipitation was investigated. The Pb ion precipitated at pH = 8.0 and pH = 6.2 while Cd ion at pH = 8. The As ion did not show precipitation effect in any soil according to the majority of arsenate ions at the actual redox potential. Although the solubility of CdS (pK = 26.1) and PbS (pk = 26.6) is similar, the Cd concentration in the solution was higher than that of Pb. The difference between the two ion concentrations is interpreted by the stronger Pb ion adsorption to organic and inorganic soil constituents. It indicated that the adsorbed and complex ion should be considered for the prediction of precipitation.

    Opis:
    Contamination of soil with heavy metals has become a worldwide environmental problem, and receives great attention. In this study, we aim to investigate soil pollution level affected by an industrial district nearby. The total amount of typical heavy metals in the soils (Hengyang Songmu Industrial Park, Hunan Province, China) was analyzed. In addition, the fraction analysis and laboratory simulation leaching via different pH rainwater was carried out to study the migration and transformation of heavy metals. The main results show that the contents of Cu, Zn, Pb, Cr and Cd in the samples were higher than the soil background values in Hunan Province. The heavy metals forms, analyzed by sequential extraction method, show that the proportion of the unstable form of Cd, Zn and Pb was more than 50%. Igeo values indicate that the heavy metal pollution degree of soil sample #5 at the investigated area is recorded in the order of Cd(6.42), Zn(2.28), Cu(1.82), Pb(1.63), and Cr(0.37). Cu, Zn, Pb, Cr and Cd in this area could pose a potential leaching risk to the environment which may affect the food chain and constitute a threat to human health. It would be necessary to take steps to stabilize and monitor the heavy metals in soil.

    Opis:
    In the study suitability of water quality index approach and environmetric methods in fi ngerprinting heavy metal pollution as well as comparison of spatial variability of multiple contaminants in surface water were assessed in the case of The Gediz River Basin, Turkey. Water quality variables were categorized into two classes using factor and cluster analysis. Furthermore, soil contamination index was adapted to water pollution index and used to fi nd out the relative relationship between the reference standards and the current situation of heavy metal contamination in water. Results revealed that surface water heavy metal content was mainly governed by metal processing, textile and tannery industries in the region. On the other hand, metal processing industry discharges mainly degraded quality of water in Kemalpasa and Menemen. Furthermore, Kemalpasa region has been heavily affected from tannery and textile industries effl uents. Moreover, pollution parameters have not been infl uenced by changes in physical factors (discharge and temperature). This study indicated the effectiveness of water quality index approach and statistical tools in fi ngerprinting of pollution and comparative assessment of water quality. Both methods can assist decision makers to determine priorities in management practices.

    Opis:
    Increasing pollution of the environment causedby heavy metals is becoming a significant problem in developing cities. Species andcultivars of plants for urban plantings shouldexhibit tolerance to these pollutants, andwhat is even more significant, through their absorption they shouldred uce the level of environmental contamination. The aim of the research was to determine whether Berberis thunbergii (DC.), which was grown in the immediate vicinity of roads, developed mechanisms limiting harmful effects of accumulating heavy metals. The mechanism for heavy metal resistance, involving the generation of phytochelatins (PCs), was investigatedin relation to As, Cd, Cr, Co, Cu, Hg, Ni, Pb andZn accumulation. Levels of thiols, i.e. glutathione (GSH) andphytochelatins (PCs), increasedin plants grown in pollutedareas in the city of Poznań in comparison to a residential site (control) and it was related to the activity of phytochelatin synthase (PC-synthase) andthe accumulation of metals. The results indicate that in Berberis thunbergii growing in the polluted urban environment a defense mechanism adapting the plant to potentially adverse conditions was initiated.

    Celem pracy było zbadanie zawartości metali ciężkich w glebach wybranych parków usytuowanych w strefach śródmiejskich oraz na obszarach peryferyjnych miast. Zawartość analizowanych metali ciężkich (Zn, Pb, Cu, Cd) w badanych glebach wykazywała duże zróżnicowanie w zależności od intensywności presji antropogenicznej. Gleby parków usytuowanych w strefie śródmiejskiej cechowały się kilkakrotnie większą koncentracją analizowanych pierwiastków śladowych niż gleby parków z obrzeży wytypowanych miast.
    The purpose of this scientific paper was an examination of the heavy metal content in soils of selected parks situated in city centre zones as well as in the city suburbs. The content of heavy metals (Zn, Pb, Cu, Cd) in the examined soils showed high diversity depending on the intensity of anthropogenic pressure. The soils of parks situated in the city centre zone were characterised by a several-times higher concentration of the analysed trace elements than the soils of parks in the city suburbs.

    Opis:
    Coastal areas in Anantigha are utilized as dumpsite for industrial and domestic wastes including effluent from local industries and inhabitants of the area despite their usage for crop cultivation. Thus, the present study was designed to assess the concentration, pollution load and ecological risk of heavy metal in Anantigha coastal area. Standard pollution indices such as contamination factor (Cf), degree of contamination, pollution load index (PLI), enrichment factor (EF), geo-accumulation index (Igeo) and ecological risk index were deployed to assess the level of heavy metals contamination in the area. The results showed that the sediment was acidic under dried conditions and low in conductivity. The mean concentration levels of all the heavy metals were lower than their mean background values except for Al. The orders of dominance for concentration of heavy metals were: Al>Fe>Mn>Cu>Zn (Station 1) and Al>Fe>Mn>Zn>Cu (Stations 2, 3 and 4). Analyzed data showed that the sediments in the area are contaminated with Al with Igeo result showing station 2 and 4 been moderately to heavily contaminated with Al while station 4 was heavily contaminated with aluminium. Station 1 had low degree of contamination, whereas station 2 and 4 had moderate degree of contamination, and station 3 showed considerable degree of contamination. The PLI result indicates unpolluted condition and the area were not enriched by the studied heavy metals as shown by EF values. Hence, the sediment in Anantigha coastal marine area was classified as having low ecological risk factor. However, the levels of these metals are not static; there is tendency for increase as a result of increased human input and activities. Hence, there is a need for regular soil testing.

    Opis:
    In this study, non-sintered ceramsite was prepared using coal gasification coarse slag obtained from a methanol plant. The basic performance and heavy metal leaching toxicity were analyzed. The results showed that seven out of nine non-sintered ceramsite groups were in accordance with the national standard of compressive strength (5 MPa), while only three groups met the national standard of water absorption index of less than 22%. The heavy metal concentrations in these three groups were found to be lower than that specified in National Class IV of surface water environment standards. The concentration of Cr was found to be 16.45 μg/L, which represents only 1% of the IV standard. The optimum mixing ratio, which showed high compressive strength (6.76 MPa) and low water absorption (20.12%), was found to be 73% coal gasification coarse slag, 15% cement, and 12% quartz sand. The characterization using Fourier transform infrared spectroscopy showed that the formation of gelatin in ceramsite enhances the performance of the ceramsite base and increases the immobilization of heavy metal. The study proved that the preparation of non-sintered ceramsite using coal gasification coarse slag reduces its environmental risk and achieves efficient utilization of the slag. Therefore, it can be concluded that it is a feasible and environmental friendly method for the disposal of coal slag.

    The river Nile is a dominating physical feature of the north- eastern part of the African continent, covering areas exhibiting varieties and contrasts in topography, climate vegetation and people. So, in this study, we estimated the contamination of the Nile sediment with some major and trace heavy metals in core samples which can cause some undesirable health effects. Concentrations of all elements shows that the maximum enrichment is found in the top subsamples, while the most elements shows low contents in the lower layer reflecting the impact of human activity on the sediment contents. Different normalizing methods were used, i.e. geoaccumulation (Igeo) and enrichment factor (EF), for the influence of the natural variability in sediment mineralogy and to assess whether the concentrations observed in surface sediment represent background or contaminated levels. The study has also shown the importance of different sediment characteristics in spatial distribution of heavy metals in the sediments of river Nile. To protect the ecological system of river Nile watershed, industrial mining and agricultural activities along river stream should to be strictly regulated.

    Opis:
    Accumulation of Cd, Pb, Zn, Cu (HM) by spring barley (Hordeum vulgare L.) from sod podzolic sandy loam and chernozem soils, impacted by heavy metals pollution in the soils, is studied in the article. The aim of study has been to determine spring barley bioaccumulation capacity impacted by the HM pollution with the high level of Cd, Pb, Zn, Cu concentration in soils. The HM concentration diapason caused biomass reduction – the scope of toxic tolerance was obtained. The range of contaminants concentration in soil, which caused the plant biomass reduction, from the beginning to plants death – the scope of toxic tolerance, is the index of a species reaction on selected xenobiotic. It shows: “threshold” concentration of a contaminant that caused a plant biomass inhibition; toxic process development and the correlation between contaminants concentration in soil and/or plant and the plants inhibition; the concentration that caused the plant death. Spring barley accumulation indexes of the studied metals were calculated. Relevant scopes of the plant-uptake index for each metal were calculated. Dynamics of the toxic process development of spring barley as impacted by the pollution in the break-down by studied metals were observed on two different soils. Toxic process dynamic evaluation gives the possibility to simulate concentration of the trace metal in plants, concentration of available forms of these elements in soils, and also contamination level (content of metals) that caused plants height and plant weight reduction by 10%, 50% and 90%.
    Celem pracy było określenie wpływu zanieczyszczenia gleb piaszczysto-gliniastych bielicowych i czarnoziemów przez metale ciężkie (Cd, Pb, Zn, Cu) na bioakumulację tych pierwiastków w jęczmieniu jarym (Hordeum vulgare L.). Podwyższone stężenie metali ciężkich spowodowało spadek plonu biomasy (od 10 do 90%). Stwierdzono, że im wyższe stężenie pierwiastków w glebie tym reakcja negatywna roślin była większa, aż do zamierania roślin. Wyliczono wskaźniki akumulacji dla każdego z pierwiastków metali. Ocena dynamiki procesu zanieczyszczenia gleb przez metale ciężkie (na podstawie wskaźników akumulacji) daje możliwość stymulowania stężenia tych pierwiastków w glebie.

    Migration and concentration of heavy metals in infiltration waters within unsaturated and saturated zones of a carbonate massif result from their mobility as well as anthropopression. The purpose of this project, carried out in 1995-2005, was to observe changes in the chemical composition of infiltration waters, especially Sr, Ba, Fe, Mn, and Zn concentration in precipitations, in soils and in caves within an unsaturated zone and a saturated zone situated in a carbonate massif. Field research was conducted in the Prądnik River’s drainage basin and at the Zakrzówek horst in Kraków. The chemical and mineralogical composition of limestone samples from 11 different quarries and natural exposures in the Kraków Upland were studied. The mineralogical research was conducted using the Roentgen diffraction method. The concentration of Sr, Ba, Fe, Mn and Zn in 700 samples from precipitation, caves and saturated zone waters was analysed. The determinations were made using mainly the ICP-AES Plasma 40 and ICP-MS Elan method. To assess the quality aspects of the migration of heavy metals, the results of the geochemical modelling were accounted for using the PHREEQC software. The hydrochemical research has shown distinct variability of concentrations of the analysed minor elements in different forms of precipitation (the highest concentrations being observed in sleet and the lowest in pure snowfall). In rainwater as well as in waters of the unsaturated and saturated zones, quantities of the five chemical elements appeared in the following decreasing order: Fe>Zn>Mn>Sr>Ba and Sr>Ba>Fe>Zn>Mn. The chemical composition of infiltration waters in the carbonate massif changes vertically. The fundamental trends in the waters of this area include an increase of Sr and Ba concentrations, a decrease of the concentration of Zn, and static concentrations of Fe and Mn.

    Opis:
    Toxic pollutants of industrial origin can be dangerous for professionals who come into contact with them at work, and also for the people who live near the sources of environmental hazards. There is a known relationship between the soil pollution with heavy metals and the morbidity of the population. This paper reports a study of the soil pollution with ions of heavy metals in the Turkestan region, Kazakhstan. The study found technogenic geochemical anomalies of various size, intensity and origin in the soils of the Turkestan region. The distribution of lead, copper, barium, zinc, molybdenum, phosphorus and arsenic was mapped based on the ecological and geochemical survey of the upper soil layer. The most polluted city is Kentau, where concentrations of Pb, Mo, Cu, Zn, As, Cd, Mn, Cr, Ni in the soil exceed the allowable level. The cause of pollution is erosion that occurs in the areas of technogenic waste storage. In some communities, the concentration of only one metal exceeded its MAC or the Clarke number, for example, only scandium exceeded its Clarke number by 1.1 in Lenger and only exceeded its Clarke number by 2.75 in Sholakkorgan.

    Opis:
    Root vegetables have greater risk of metal contamination from compost application to soil than other horticultural crops. Moreover, soil organic amendments pose potential environmental hazards. The objective of the present study was to examine the heavy metal uptake in different tissues (petiole, blade, skin, pulp) of Raphanus sativus exposed to organic amendments doses. The impact of the above materials on heavy metal concentration of the soil and plant development parameters were also evaluated. A pot experiment was established with eight treatments arranged in a randomized complete block design and four replicates. Co-compost of sewage sludge and olive wastes at 100, 200, 300 m3 ha–1, composted olive leaves, olive tree pruning wastes, olive mill pomace and poultry manure at 100, 200 m3 ha–1, commercial liquid organic fertilizer at 50 Kg ha–1 with or without inorganic NPK fertilization and a no fertilizing control, were applied to plants. The results showed that sewage sludge application strongly increased the yield and improved radish size cultivated in silt loam soil. The edible radish part had the lowest Fe, Mn, Cu, Zn, and Cr content, whereas the highest Mn, Cu, Zn, Cr was found in the blade and increased Fe, Ni, Pb were recorded in the skin. Organic treatments gave higher Fe, Mn, Cu, Zn amount in both aerial plant tissues compared to the control soil, while Ni, Pb, Cr of all the radish parts were not affected by treatments. This study suggested that organic amendments application gave low permissible levels of all metal content in radish tissues and increased radish productivity. Therefore, organic materials used herein can be applied for normal plant growth without metal contamination of the plant and the soil.

    Opis:
    W pracy przedstawiono czasową zmienność zawartości metali ciężkich oraz ocenę jakości osadów dennych małego zbiornika w Zesławicach, na rzece Dłubni. Wyniki badań prowadzonych w latach: 1998, 2001, 2003, 2005, obejmowały zawartości: Cr, Ni, Cu, Zn, Cd i Pb. Badania wykazały podwyższone wartości metali ciężkich w latach 1998 i 2001, stan taki wynika z wpływu wezbrań, w wyniku których nastąpiła intensywna akumulacja osadów wraz z zanieczyszczeniami wymytymi z obszarów objętych powodzią. Wyniki badań przeprowadzonych w późniejszych latach wykazują zmniejszanie się zawartości metali ciężkich w wierzchniej warstwie osadów. Ocena jakości osadów dennych wykonana według różnych kryteriów wykazała brak potencjalnego zagrożenia dla środowiska wynikającego z akumulacji w nich pierwiastków śladowych.
    The paper presents variability in time of heavy metal concentrations in bottom sediments of small water reservoir at Zesławice, situated on the Dłubnia river. The presented results of research on the chemical properties of sediments conducted in 1998, 2001, 2003 and 2005 determined the sediment concentrations of chromium, nickel, copper, zinc, cadmium and lead. The analyses revealed elevated heavy metal concentrations in 1998 and 2001. This state might have been due to the effect of high water levels, which occurred in the period prior to the sample collection. The results of research conducted in the subsequent years show decreasing heavy metal content in the top layer of the bottom sediments. The assessment of the sediment quality did not reveal any potential hazard to the environment resulting from trace element accumulation in bottom sediments.

    Opis:
    Jeddah is the most industrialized city on the west coast of Saudi Arabia and is under increasing influence of human activities. Heavy metals data were obtained from four near-coast Red Sea sediment cores in close proximity to Jeddah. Chromium, manganese, iron, copper, zinc, and lead were analyzed from depth-resolved sections of each core via heavy acid digestion and inductively coupled plasma-mass spectrometry (ICP-MS). The average concentrations of all four sites were 245.96 mg kg1, 478.45 mg kg1, 8506.13 mg kg1, 251.82 mg kg1, 623.09 mg kg1, and 362.75 mg kg1, respectively. The depth-resolved results showed that highest concentrations of Mn, Cu, and Pb were found in the top 15 cm of the core profile distributions compared to other depth sub-samples. Heavy metal concentrations in core sediments are increased near central Jeddah and have become higher in recent years. The results of enrichment factor calculations indicate little anthropogenic supply of Mn and Cr while Pb, Zn, and Cu show strong anthropogenic input. The Pollution Load Index was higher in the two sites closer to central Jeddah where power and desalination plants and wastewater release are known. This indicates that the area has suffered from heavy metal pollution compared to other non-industrialized sites in the Red Sea. Heavy metal contaminations due to anthropogenic activity should be taken into account to protect the Red Sea during future growth. The results of this work should be considered as a baseline for heavy metals monitoring in the sediments of the Red Sea coast near Jeddah, Saudi Arabia.

    Opis:
    Intraspecific changes in genome size and chromosome number lead to divergence and species evolution. Heavy metals disturb the cell cycle and cause mutations. Areas contaminated by heavy metals (metalliferous sites) are places where microevolutionary processes accelerate; very often only a few generations are enough for a new genotype to arise. This study, which continues our long-term research on Viola tricolor (Violaceae), a species occurring on both metalliferous (Zn, Pb, Cd, Cu) and non-metalliferous soils in Western and Central Europe, is aimed at determining the influence of environments polluted with heavy metals on genome size and karyological variability. The genome size of V. tricolor ranged from 3.801 to 4.203 pg, but the differences between metallicolous and non-metallicolous populations were not statistically significant. Altered chromosome numbers were significantly more frequent in material from the polluted sites than from the non-polluted sites (43% versus 28%). Besides the standard chromosome number (2n = 26), aneuploid cells with lower (2n = 18–25) or higher (2n = 27, 28) chromosome numbers were found in plants from both types of site, but polyploid (2n = 42) cells were observed only in plants from the metalliferous locality. The lack of correlation between chromosome variability in root meristematic cells and genome size estimated from peduncle cells can be attributed to elimination of somatic mutations in generative meristem, producing chromosome-stable non-meristematic tissues in the peduncle.

    Opis:
    This work was undertaken to determine lipids changes in needles of Scots pine (Pinus sylvestris L.) populations growning on polluted stands near a phosphate fertilizer factory in Luboń, and copper smelter in Głogów and in a control area in Kórnik. Needles from polluted areas had a lower content of total phospholipids than samples from the unpolluted site. Greater changes were detected in membranes of needles collected in October and January. In comparison with the control total phospholipid in needles of populations from polluted areas were 14 to 33% lower. Phosphatidylcholine (PC) phosphatidylethanolamine (PE) and phosphatidylglicerol (PG) were the dominant phospholipids. The analysis of fatty acids in phospholipid fraction showed a decrease of linoleic acid (18:2) and linolenic acid (18:3) contents. The level of polyunsaturated fatty acids in needles of three populations from polluted areas was up to 40% lower as compared with the control. Moreover, phospholipids and their fatty acids showed seasonal fluctuations. The contents of PC, PG and PE increased in autumn and in winter, during the process of cold acclimation. In July, current-year needles did not show significant differences in membrane lipid composition between the polluted areas of Scots pine populations. The results suggest that the lipid changes of needles could be associated with disturbances in phohospholipid metabolism, caused by environmental pollution.

    Opis:
    Thirty two active stream sediment samples were collected, panned and sieved from a 16km (500m spacing) section along Ndongo River, Buea. Sixteen of them were subjected to magnetic separation for the determination of heavy minerals under a microscope (KARL ZEISS IENA) and analyzed by XRF and AAS for As, Be, Cd, Co, Cu, Cr, Mo, Ni, Pb, Rb, Sb, Sc, Sn, Sr V, Zn, and Zr. The average element concentrations are 0.014, 64.45, 76.93, 94.52, 87.65, 147.79, 0.00, 77.00, 98.99, 40.37, 7.99, 24.70, 52.42, 1053.37, 285.46, 579.70 and 404.41ppm respectively. As (0.014 ppm) and Mo (0.001 ppm) are below l average concentrations in basalts while dispersed Be, Cd, Co, Cu, Cr, Ni, Pb, Sb, Sc, Sn, V, Zn values are mostly above tolerance limit in settlement areas and farmlands. Olivine with angular grains (1.5mm) and sub-hedral shape representing 10 vol. % is light green colored. Together with pyroxene (elongated, black colored with angular grains up to 0.7mm) are the most abundant minerals. Minor rutile with shiny luster is also present. R-mode factor analysis reveals Ni-Rb-V, Co–Cr–Pb–Zn, and Cu–Sr-Zr associations representing three geochemical entities related to agricultural (fertilizers) and settlement (domestic waste) areas. Correlation coefficients (r) vary from -0.84 (V, Sb) to 0.728 (Ni, Rb) and may indicate different sources of metal contamination. The calculated PLI (3.10 to 4.92) and Igeo (-7.37 to 9.18) of As, Be, Cd, Co, Cu, Cr, Mo, Ni, Pb, Rb, Sb, indicate metal pollution of River Ndongo sediments. The obtained classification is defined as low (As, Co, Cu, Cr, Mo, Ni, Sc, and V), partially (Co, Zn), moderately (Pb, Be) and highly to very highly (Sb, Sr, Cd) polluted. Natural and anthropogenic metal input assessment reveals that the dominantly basaltic lithologies in the area (pyroxene and olivine), the domestic and agricultural activities as well as urbanization processes of Buea are the main source of metal contamination.

    Earth surface is under the continous influence of the environmental factors – both natural and anthropogenic. The significant impact on the environment can be noted in areas adjacent to the metal industry plants, in a consequence of pollutants emission, especially dusts containing the heavy metals, into the atmosphere,. In the surroundings of Głogów Copper Smelter (GCS) elevated amounts of copper and lead has been noted. In the soils of the test sites were found up to 5250 mg kg-1 Cu and 1290 mg kg-1Pb. The forest litter contained 3.3-5.1 more Cu and 3.9-8.6 Pb than the humic horizon of the soil. Analyse of the different soils covering the GCS protective forest area let specify the stabilising role of particle size distribution, TOC content and the soil reaction to Cu and Pb migration in the environment.
    Powierzchnia ziemi jest nieustannie narażona na oddziaływania o charakterze naturalnym i antropogenicznym. Znaczące oddziaływanie jest łatwo zauważalne na terenach przemysłowych. Szczególnie na obszarach objętych wydobyciem i przeróbką metali. Na terenach przyległych do Huty Miedzi Głogów stwierdzono wysoką koncentrację miedzi i ołowiu sięgającą 5250 mg・kg-1 Cu i 1290 mg・kg-1 Pb. Poziom ściółki leśnej zawierał 3,3-5,1 raza więcej Cu i 3,9-8,6 Pb niż poziom próchniczny analizowanych gleb. Analiza różnych gleb pokrywających las ochronny HMG pozwoliła wskazać na znaczącą rolę składu granulometrycznego, zawartości węgla organicznego oraz odczynu na stabilizację migracji Cu i Pb w środowisku.

    Opis:
    The present study was initiated to understand the accumulation of toxic heavy metals in sediments of Bhavan's College Lake of Andheri, Mumbai. The study was performed for a period of one year starting from June 2011 to May 2012 to quantify the toxic heavy metals like Cu, Pb, Cr, Ni, Fe, Hg, As and Cd by atomic absorption spectroscopy technique coupled with cold vapour technique (for Hg analysis) and hydride generation technique(for As analysis). It was observed that the yearly average concentrations of these heavy metals in lake sediments were 0.53, 0.25, 0.42, 0.43, 4.6, 0.14, 0.12 and 0.11 ppm respectively which were above the WHO limits for aquatic life and CPCB limits for inland surface water. These heavy metals accumulated in lake sediments may enter the water thereby creating threat to aquatic life. They may enter the food chain through biomagnifications and may create adverse effect on human health. It is expected that in addition to the water analysis which is practiced for years, sediment analysis performed in the present investigation will help in evaluating quality of the total ecosystem of the lake. It will also provide environmentally significant information about natural and anthropogenic influence on the water body.

A significant variability was found between sites in relation to contents of chemical elements in soils, leaves and numbers of "tar-spots". The similarity of sites presented in dendrograms classified them as industrial, urban-agglomeration and vehicle-transport areas. The factor and PCA analyses showed that two factors differentiate the soil of the sites in respect of Fe, Cu, Co, Mo, Cr, Ni, Cd and N, S, Mn, Pb. In case of leaves of A. platanoides populations differentiate them in respect of N, S, Fe, Pb, Zn, Co, Be, Cr, Cd and Mn, Cu, Mo. The different air pollutions affect significantly the numbers of "tar-spots" on leaves. Sites with the highest contents of elements do not show "tar-spots", and the factors restricting their occurrence are the high contents, mainly of N, S (NOX, SOX) and heavy metals. In sites, with the lowest contents of these elements massive infections take place. The occurrence of R. acerinium corresponding with the level of site pollution can be used as a tool for evaluation of the degree of environmental pollution.

    Opis:
    Contamination of the environment with heavy metals such as Cd is a serious problem of modern world. Exposure of plants to Cd leads to oxidative stress, inhibition of respiration and photosynthesis, increased rate of mutation and, as a consequence, stunted growth and yield decrease. One of the common reactions of plants to cadmium stress is over-production of ethylene, however the exact role of this hormone in plants response to Cd is still unrecognized. The aim of the present study is evaluation of the impact of an ethylene synthesis inhibitor, Co, on the response of soybean seedlings to cadmium stress. The experiments included measurements of growth, cell viability, ethylene production and expression of genes associated with cellular signaling in soybean seedlings exposed to CdCl2 (with Cd in a concentration of 223 μM) and/or CoCl2 (with Co in concentration of 4.6 μM). Surprisingly, the results show that Co has no effect on ethylene biosynthesis, however, it affects cell viability and expression of Cd-induced genes associated with plant signaling pathways. The affected genes encode mitogen-activated protein kinase kinase2 (MAPKK2), nitrate reductase and DOF1 and bZIP2 transcription factors. The role of Co in plants response to cadmium stress and its potential use as an ethylene inhibitor is discussed.

    Opis:
    The paper characterises total concentrations of Cd, Cu, Ni, Pb, Zn in the surface layers (0-20 cm) of agricultural soils in Poland (48620 soils samples) and Lublin region (3829 soil samples). The results for Lublin region are expressed in terms of the degree of metal pollution as compared to contamination in the rest of the country. The average concentration of Cd, Cu, Ni, Pb and Zn (in mg kg-1 of soil) in the A horizon of agricultural soils in Poland and in Lublin region (values in parenthesis) are as follows: 0.21 (0.17); 6.5 (4.9); 6.2 (6.6); 13.6 (10.7); 32.4 (23.3). About 79% of the agricultural soils in Poland are characterised by a natural (0°) content of heavy metals while 17.6% contain elevated level (10) of these metals. In the Lublin region it is 91.9% and 6.7%, respectively. About 3% of the Polish soils (1.4% in the Lublin region) exhibit various degrees of contamination with heavy metals. This includes heavy (IV0) and very heavy pollution (V0) which is found in up to 0.4% of the agricultural land and up to 0.2% in the Lublin region.

    Opis:
    Soil contamination of areas covered by industrial plants and farms is one of the major environmental problems whose weight is underestimated in Poland and Europe. Such regions are usually not as exposed to direct pollution as highly urbanized industrial areas. On the other hand, they are usually less strictly monitored than protected areas. The District of Olkusz, an example of such a region, is characterized by well-developed agriculture, regressing local industry and growing tourism industry. However, it borders with Silesia, a heavily industrized area. The study reports the condition of arable soils in Olkusz District in terms of their contamination with lead, cadmium, zinc and copper. The atomic absorption spectrometry (AAS) method was used to determine the concentrations of the metallic elements. The parameters like pH, content of the clay fraction and content of organic matter have been also taken in consideration to assess the bioavailability of the metals. The analytical results showed that, despite the decreasing impact of the local industry, levels of concentration of all the studied metals are significantly higher than their average concentration in Polish soils. Moreover, all the calculated Pearson correlation coefficients between concentrations of the metals were above 0.9, which means they correlate each other strongly. The impact of the local pollutants (mainly Bukowno smelter) in connection with the proximity of the Silesia and the high vulnerability for contamination of the soils precludes agricultural use of the ground in at least half of the cases.

    Opis:
    The photochemical activity of photosystem II (PSII) was measured by chlorophyll a fluorescence intensity of Scots pine needles, from trees growing in various forest experimental areas exposed to air and soil pollution. Fluorescence techniques was used as a no-invasive method of detection injuries of the photosynthetic apparatus. Chlorophyll fluorescence parameters such as PSII photochemical efficiency (Fv/Fm), chlorophyll fluorescence decrease ratio (Rfd) and size of the acceptor pools available to PSII (Sm) indicated seasonal changes in the activity of the photosynthetic apparatus of pine needles. Significant differences in the variable fluorescence parameter rations Fv/Fm and Rfd between the studied sites were found in middle-winter dormancy period in January and also in samples collected in August. Winter inactivation of photosynthesis results in areduction of the photochemical efficiency Fv/Fm and Rfd. Presented results demonstrate that the effect of industrial pollution on Scots pine needles is detectable by of measurements of fluorescence parameters. They showed that Scots pine trees indicated physiological adaptation to environmental pollution and this can be monitored by the fluorescence signals earlier than by other methods.
    Badano fotochemiczną aktywność fotosystemu II (PS II) igieł sosny zwyczajnej mierząc fluorescencję chlorofilu a igieł trzech populacji rosnących pod wpływem skażenia gleby i powietrza. Analizowano następujące parametry fluorescencji chlorofilu a: Fv/Fm, Rfd i Sm/Fm. Stwierdzono ich sezonowazmie - nność. Istotne różnice statystyczne pomiedzy stanowiskami wzrostu badanych populacji wystąpiły dla parametru Fv/Fm i Rfd w okresie spoczynku zimowego w styczniu. Zaburzenia fotosyntezy zimą prowadzą do redukcji wydajności fotochemicznej wyrażonej stosunkiem Fv/Fm i Rfd. Uzyskane wyniki wskazują iż kondycję drzew iglastych rosnących w skażonym środowisku można ocenić przez pomiar fluorecencji chlorofilu a w igłach. Przedstawione badania wspierają hipotezę zakładającą, że sosna zwyczajna należy do drzew o wyraźnej fizjologicznej zdolności adaptacji do skażonego środowiska.

    W pracy przedstawiono wyniki badań zawartości Mn, Zn, Cu, Cd, Pb i Ni w wodzie, osadach dennych i liściach roślin wodnych (trzciny pospolitej - Phragmites australis (Cav.) Trin. EX STEUD., pałki szerokolistnej - Typha latifolia L., grążela żółtego - Nuphar lutea (L.)

STR.), pobranych z 13 stanowisk, zlokalizowanych w strefie litoralnej Jeziora Wielkiego (Pojezierze Leszczyńskie). Przeprowadzone badania wykazały zbliżone zdolności kumulacyjne metali, u makrohydrofitów należących do tej samej grupy ekologicznej - wyraźne grupy stanowiły rośliny o liściach pływających oraz rośliny wynurzone. Wykazano również wysokie zdolności kumulacyjne Ceratophyllum demersum, zwłaszcza w stosunku do Mn. Jego liście zawierały ponadto największe ilości Zn, Cu, Cd i Ni. Wszystkie badane gatunki makrohydrofitów, niezależnie od budowy morfologicznej, charakteryzowały się takim samym szeregiem zawartości metali w liściach: Mn > Zn > Cu > Pb > Ni > Cd. Liczne dodatnie korelacje pomiędzy zawartością metali w roślinach a ich zawartością w środowisku świadczą o możliwości wykorzystania badanych makrohydrofitów w bioindykacji skażenia środowiska metalami ciężkimi.
    The contents of Mn, Zn, Cu, Cd, Pb, and Fe were determined in water, bottom sediments and leaves of macrohydrophytes - Phragmites australis (Cav.) Trin. EX STEUD., Typha latifolia L., Nuphar lutea (L.) SlBTH. & Sm, Nymphaea alba L., Hydwcharis morsus-ranae L., Ceratophyllum demersum L. S. STR. - from 13 study sites, situated in littoral of Wielkie Lake (Leszczyńskie Lakeland). The results showed that submerged plants contained higher levels of trace elements than emergent and floating-leaved macrohydrophtes. Ceratophyllum demersum contained the highest amounts of Mn, Zn, Cu, Cd, and Ni, it also showed very high Mn accumulation ratios. All examined water plants, irrespective of life form, were characterized by the same sequence of heavy metal concentrations which was as follows: Mn > Zn > Cu > Pb > Ni > Cd. The significant, positive correlations found between the content of heavy metals in plants and levels of these elements in the environment indicate the possibilities of using examined macrohydrophytes to biomonitoring of environmental contamination with heavy metals.

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.

    Opis:
    River floodplains have been recognized as an important sink for suspended sediments and associated contaminants mobilized from upstream catchments. However, information on rates of overbank sedimentation within time span of several tens of years is impossible to obtain using conventional sediment traps. Measurements of the 210Pb content in floodplain sediments provide an alternative approach for obtaining estimates of medium-term (100–150 years) rates of overbank sediment deposition. The use of 210Pb method and heavy metals concentration profiles allowed to obtain retrospective estimates of recent sedimentation rates on floodplain of the Warta River (the Cracow Upland, southern Poland). The results are compared with dating of sediment layers by characteristic peaks of heavy metal concentrations. The highest sediment accretion rate, of the order of 1 cm/year, was found in a levee along river bank. Sediment deposition in flood basin is much slower and usually does not exceed 1 mm/year.

    Opis:
    The high level of cadmium in the abdominal muscle of the brown shrimp Crangon crangon is due to the serious pollution of the water in the Gulf of Gdańsk. The inhibition of malic enzyme (ME) activity by cadmium, and in consequence the reduced formation of NADPH, could interfere with cellular mechanisms for detoxifying the organism and reducing oxidative stress. The reduced glutathione (GSH) concentration in the abdominal muscle of C. crangon was calculated to be 5.8 mM. The objective of this study was to evaluate the part played by GSH in the effect of cadmium on the activity of NADP-dependent malic enzyme from abdominal muscles of brown shrimps. This enzyme is activated by certain divalent cations (Mg, Mn). The results demonstrate that cadmium inhibits ME activity from shrimp muscle, and that GSH and albumin can reduce this cadmium-inhibited NADP-dependent malic enzyme activity.

    Opis:
    Carotenoids (neoxanthin, violaxanthin, lutein and β-carotene) present in plant cell play a role in photoprotection. Industrial pollution causes oxidative stress in plants, while carotenoids react with free radicals and dissipate the excess of excitation energy. In this way carotenoids prevent the negative influence of free radicals on metabolism and can even restore some of the damages. This is confirmed by results of our analysis of the level of xanthophylls in 16 and 17-year-old trees of Scots pine (Pinus sylvestris L.). Developed from seed collected in north-eastern, the trees grow in a relatively unpolluted control site, and in a polluted site located 2 km for away from the Phosphorus Fertilizer Works. In the polluted site the environment is contaminated with SO2, NOx and F, Al, F, Pb, Cu. The needles analysed in this study were visually undamaged. Material was collected in experimental plot from 6 trees in October'98 and April'99, between 12.00 and 13.00 hours, at full sunlight. The pigments were analysed quantitatively and qualitatively by thin-layer chromatography. The paper presents results of content and distribution of neoxanthin, violaxanthin, lutein and β-carotene of Scots pine needles from a healthy control tree and a stressed tree. Marked differences in pigment levels depended on the stage of needle development and level of pollution.

    Opis:
    The content of heavy metals in peat soils of north part of Słupsk Region was low. Enrichment factors for Cd, Zn and Mn indicates on their anthropogenic origin in studied peat soils, and for Cr and Ni - natural origin. However copper may be of anthropogenic or natural origin depending on location. The farther from sea peat soils are situated the higher concentration of those metals is.
    W pracy analizowano zawartość niektórych metali cieżkich (Cu, Zn, Cd, Mn, Cr, Ni) w glebach torfowych Ziemi Słupskiej (Środkowe Pomorze). Koncentracja tych metali w badanych glebach jest niewielka, niemniej jednak wyznaczone współczynniki wzbogacenia wskazują, że Cd, Zn i Mn są pochodzenia antropogenicznego, natomiast Cr i Ni - pochodzenia naturalnego. Pochodzenie miedzi było zależne od lokalizacji gleb torfowych. Im dalej od morza były usytuowane badane gleby, tym więcej zawierały analizowanych metali.

    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.

    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:
    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:
    Background. Heavy metals are at present classified among the most important and dangerous water pollutants. Since over 15 years parasites have been used as a bioindicators of water pollution, e.g. using their ability to accumulate heavy metals. Concentration of four elements (Zn, Cd, Ni, Cu) in selected organs of the perch (Perca fluviatilis) and in the tissues of its parasite, plerocercoid of the tapeworm Triaenophorus nodulosus, was analysed. Material and methods. The fish were subject to full helminthological section, resulting in 66 tapeworm larvae isolated from cysts, located in the liver. Plerocecroids, gills, liver and intestine with duodenum were removed and frozen. Content of heavy metals was determined with atomic absorption spectroscopy method. Results. The distribution of the content of Ni, Cd and Zn was similar. In all cases, among all the examined fish organs, the highest mean concentration of the metals was found in the liver, followed by the intestine; it was the lowest in the gills. The mean concentration of the metals in the tapeworm tissues was from 6 to 74 x higher than in the gills, 5−37 x higher than in the intestine and 2.5−28 x higher than in the liver. The concentration of Cu was also the highest in the tapeworm tissues, but its concentration in the fish intestine and liver was nearly the same; it was the lowest in the gills.

    Opis:
    W pracy przedstawiono wyniki badań zawartości makroelementów i metali w osadach oraz w liściach i kłączach pałki szerokolistnej z 7 stanowisk z okolic Nysy (południowo-zachodnia część województwa opolskiego). Badane osady są słabo zasobne w N, P, K, Mg i Na, jedynie zawartość Ca jest duża. Natomiast zawartości metali nie przekraczają wartości tła. Zawartości makroelementów w liściach i kłączach pałki szerokolistnej jest średnia lub mała (P i Mg), jedynie zawartość Na przekracza zazwyczaj górny zakres. Większość metali (Fe, Zn, Cd i Cu) charakteryzuje podobny sposób rozmieszczenia w roślinie, najwięcej jest ich w kłączu, mniej w szczytowej części liścia, a najmniej w jego dolnej części. Wartości sum ważonych wyliczone dla części dolnych i szczytowych liści pałki szerokolistnej przekroczyły wartość 12,5, co spowodowane jest głównie podwyższoną zawartością sodu i wapnia w liściach. Istotne dodatnie korelacje pomiędzy zawartością metali w organach palki szerokolistnej a ich zawartością w osadach dennych świadczą o możliwości wykorzystania badanego gatunku w bioindykacji skażeń środowiska metalami ciężkimi.
    The contents of macroelements (N, P, K, Ca, Mg, Na) and heavy metals (Cd, Pb, Ni, Mn, Zn, Fe) in bottom sediments as well as in leaves and rhizomes of Typha latifolia from seven water bodies in the Nysa region (south-western part of Opole Province) were determined. Examined bottom sediments contained low amounts of N, P, K, Mg and Na, while the concentration of Ca was very high. Also Na content in leaves and rhizomes of Typha latifolia exceed the upper limit, but concentrations of the rest nutrients were median or low (P and Mg). The highest level for majority of studied metals (Fe, Zn, Cd, and Cu) was found in rhizomes, less in the tip of leaf and the least in lower part of leaf. The weighed sums of square roots for relative cation concentrations in both parts of leaves were higher than 12.5 given by Czarnowski, mostly because of high Ca and Na concentrations. Significant, positive correlations found between the content of heavy metals in Typha latifolia and the levels of these elements in bottom sediments indicate a possibility of using examined plant in biomonitoring of environmental contamination with heavy metals.

    Opis:
    Zinc-lead waste dumps belong to the type of industrial waste areas which are unyielding to natural reclamation techniques. Heterogeneous composition of waste results in numerous complex physical and chemical processes causing serious air and water pollution in the surrounding areas. Moreover, industrial waste is characterized by high concentration of heavy metal compounds and other toxic substances which constantly affected all living organisms exposed to them. The present research shows the results of research aimed to establish degree of the sensitivity of Betula pendula seedlings to the adverse conditions of zinc-lead waste from the "Silesia Steelworks" in Katowice. Two kinds of substrate, i.e. slag and post-flotation waste was placed in pot cultures (17 cm in top diameter) and for each kind of waste a different soil variant was applied: (I) dump soil, (II) dump soil fertilized with NPK fertilizer, (III) dump soil covered with a 2.5 cm layer of garden soil, (IV) dump soil mixed with peat. In the experiment each variant of the soil type was used in 3 pots (repetitions). Additionally, pots with garden soil were used as control. Each pot received 25 seeds. The seeds of Betula pendula growing on smelter waste dumps had been collected in the vicinity of the dumps. At the end of the experiment, the seedlings were counted and the leaf colouring, height, root length of each seedling was measured. The results of the experiment showed that the most favourable soil type for Betula pendula seedlings were variants Nos (III) and (IV).

    Publikacja przedstawia skażenie gleby, wód i roślin przez chrom w okolicy składowiska odpadów garbarskich w Lubartowie. Przez ponad 20 lat odpady z garbarni zawierające duże ilości chromu były składowane w niezabezpieczonym wyrobisku piaskowym, które leży tuż przy rzece Wieprz. Wyniki naszych badań porównane są z wynikami raportów z początku lat 90 dotyczących skażenia chromem okolicy Lubartowa. Przedstawione jest porównanie dwóch metod określania stężenia chromu w glebie. Wyniki pokazują, że okolica składowiska odpadów jest wciąż skażona i wymaga poważnego programu oczyszczenia jej i przywrócenia do stanu przed składowaniem odpadów.
    The article presents contamination of soil, water and plant with chrominum in the vicinity of tannery waste lagoon in Lubartow. reach in chrominum wastes from the tannery have been gathered for more than 20 years in usealed basin which was situated close to the Wieprz river.results of our investigations are compared with reports on chrominum contamination of the same object but coming from early nineties. Two methods of total chrominum determination in soils are compared. The results show that the area of waste disposal is still contaminated and a serious remediation program is needed.

    Opis:
    Omówiono wyniki 5-letniego (2004-2008) cyklu badań monitoringowych żywności w zakresie zanieczyszczenia pierwiastkami szkodliwymi dla zdrowia, obejmujących zawartość ołowiu, kadmu, rtęci, arsenu i cyny w wodach mineralnych i napojach bezalkoholowych (226 próbek), owocach i ich przetworach (467 próbek), ryżu (234 próbki), ziarnie sojowym (236próbek), orzechach i orzechach ziemnych (237próbek) oraz rybach i owocach morza (237próbek). W badaniach uczestniczyły laboratoria Państwowej Inspekcji Sanitarnej oraz laboratorium referencyjne Zakładu Badania Żywności i Przedmiotów Użytku NIZP-PZH. Stwierdzone zawartości metali nie stwarzają zagrożenia dla zdrowia, są z reguły znacznie niższe od limitów ustalonych w ustawodawstwie i porównywalne ze stwierdzanymi w innych krajach europejskich, w przypadku kadmu - niejednokrotnie niższe. Uwzględniając średnie zanieczyszczenie badanych grup środków spożywczych oraz ich spożycie w Polsce oceniono potencjalne zagrożenie dla zdrowia. Spośród badanych pierwiastków najwyższe pobranie w przeliczeniu na % tymczasowego tolerowanego pobrania tygodniowego (PTWI) ma miejsce dla rtęci w rybach, które wynosi średnio 3,2% PTWI. Celowe jest przestrzeganie zaleceń dotyczących kontrolowanego spożycia ryb, szczególnie przez dzieci, a także kobiety w ciąży; karmiące i potencjalne matki. Pobranie ołowiu i arsenu z napojami i wodami mineralnymi jest rzędu 15% całkowitego pobrania tych pierwiastków z żywnością.
    Results of the 5-years cycle (2004-2008) monitoring investigations on food contamination with elements noxious to human health, involving testing of mineral waters and soft drinks (226 samples), fruits (467 samples ), rice (234 samples), soybeans (236 samples), nuts and peanuts (237 samples), fish and seafood (237 samples) are discussed. The parties involved in testing were: laboratories of State Sanitary Inspection and the national reference laboratory of the Department of Food and Consumer Articles Research of National Institute of Public Health - National Institute of Hygiene. The reported metals contents did not give rise to health concerns, remaining generally below the levels set forth in food legislation and being comparable with contamination levels reported in other European countries; and for cadmium - often lower. Health hazard assessment was performed taking into account the mean contamination levels obtained and average domestic consumption of these food products groups in Poland. The highest intake expressed as the percentage of provisional tolerable weekly intake (PTWI) was obtainedfor mercury in fish, which has reached mean 3,2% PTWI. Controlled fish consumption recommendations should be adhered to by prospective mothers, pregnant women, breast-feeding women and young children. Lead and arsenic intake with mineral waters and soft drinks comprises approx. 15%) of total intake of these elements with food.
