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.

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.

Opis:: 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%. I_geo 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.
