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

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

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

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

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

Opis:: The aim of the study was to assess the effect of bottom sediments on the selected properties of light soil as well as the content of trace elements in tested plants. The bottom sediments collected from the Besko reservoir were added to the soil in an amount of 5%, 10%, 30% and 50% of air-dried sediment, in relation to dry soil mass. The pot experiment was conducted on a light soil, with weak loamy sand grain size composition and slightly acid reaction, which was enriched with a supplement of bottom sediment. The test plant was a maize, Bora c.v. An applied bottom deposit revealed in its composition a considerable content of clay fractions, alkaline reaction and low total heavy metal content. Therefore, it may be applied as an admixture to light soils to improve their productivity. The addition of sediment to light soil resulted in the improvement of acidification in soil indicators: increased soil pH and reduced value of hydrolytic acidity, as well as improved sorption properties. A non-uniform effect of bottom sediment admixture on the content of trace elements in maize was determined. The sediment added to the soil increased the content of copper, nickel, chromium and, decreased the contents of zinc and cadmium in shoots. We did not find any excess of the permissible content of metals in plants used as animals forage in the maize biomass.

Opis:: Quality is one of the most important risk indicators in river basins. Therefore, monitoring and evaluating water and sediment quality has a very important role in process of risk management. The aim of the monitoring is provide for the sustainability of water bodies and these results are the basis for the risk management in the river catchment area. Hornad, Laborec and Poprad are the rivers in Eastern Slovakia. Hornad and Laborec belongs to basin of Danube and Poprad belongs to basin of Vistula. Sediment sampling was carried out according to ISO 5667-6. Monitoring was carried out in the spring on 2017–2018. The chemical composition of sediments was determined by means of X-ray fluorescence (XRF) using SPECTRO iQ II (Ametek, Germany, 2000). The results of sediment quality evaluated by method PERI revealed that the quality of sediment in 2018 was better than 2017. Results of XRF analysis of sediments were compared with the limited values according to the Slovak Act 188/2003 Coll. of Laws on the application of treated sludge and bottom sediments to fields. It can be state that limit values comparing with Slovak legislation were not exceeding in all sediment samples in rivers in Eastern Slovakia. Based on the monitoring data of sediment quality in the study area, a quantitative analysis of heavy-metal pollution in sediment was conducted using the method of potential ecological risk index (PERI) which is method for evaluate the potential ecological risk of heavy metals. It is based exclusively on chemical parameters of sediments because sediment data show mean integrated values in time, with higher stability than water column parameters; sediments are easily sampled at field work; sediment samples are more representative for time and space scales and analytical data are easily obtained, especially because sediments present high concentrations of contaminants, decreasing the possible errors due to detection limits of the applied analytical method. This method comprehensively considers the synergy, toxic level, concentration of the heavy metals and ecological sensitivity of heavy metals. Potential ecological risk index can be obtained using three basic modules: degree of contamination (CD), toxic-response factor (TR) and potential ecological risk factor (ER). The results show on the basis on potential ecological risk index that the quality of sediment in 2018 is better than 2017. The worst result shows Hornad in 2017. Significant improvement occurred at the sampling point S2 in Hornad in 2018. The best results show Laborec in 2018. The results show on the basis on potential ecological risk index that quality of sediment in 2018 is better than 2017.

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

Opis:: Analizie chemicznej poddano próbki osadów dennych pochodzących z rzeki Gowienica. Próbki pobierano w latach 2014 i 2015 w wybranych punktach badawczych, które wyznaczono w zależności od sposobu zagospodarowania i użytkowania terenów przyległych. W pozyskanym materiale oznaczono zawartość całkowitą metali ciężkich tj.: Cd, Co, Cr, Ni, Pb oraz Hg. Na podstawie uzyskanych wyników analiz chemicznych wykazano podwyższone stężenia ołowiu, niklu, chromu oraz rtęci, które przekraczały wartości progowe, powyżej których obserwuje się szkodliwe oddziaływanie zanieczyszczeń (TEL). Nie stwierdzono natomiast ponadnormatywnych stężeń tych zanieczyszczeń dla wyznaczonej wartości granicznej (PEL) powyżej której obserwuje się szkodliwe oddziaływanie zanieczyszczeń na organizmy. Przeprowadzone analizy chemiczne wykazały jednak przekroczenia wartości naturalnej kobaltu (tło geochemiczne 2,0 mg⋅kg^-1) dla osadów wodnych Polski w poszczególnych punktach badawczych. Przyczyną tych przekroczeń w pobranych osadach dennych były najprawdopodobniej spływy powierzchniowe z pól i łąk w formie nawozów i środków ochrony roślin oraz dopływ ścieków bytowych.
The samples of bottom sediments for chemical analysis were collected from Gowienica river and its tributaries. The samples were collected in 2014 and 2015 from the established sampling points on differently managed and utilized adjacent areas. Total content of heavy metals, i.e.: Cd, Co, Cr, Ni, Pb and Hg were measured in the collected material. The results indicate that the concentrations of lead, nickel, chromium and mercury exceeded the level indicating the harmful impact of pollution (TEL) , but none of the analyzed heavy metals exceeded the limit (PEL) above which harmful effects of pollution on organisms can be observed. However, according to another classification (LAW), the analyzed sediments were between two classes (unpolluted deposits – Class I), and unpolluted / moderately polluted deposits (class I-II). Nevertheless, a chemical analysis showed that the natural cobalt concentration (geochemical background; 2.0 mg⋅kg-1) for aquatic sediments in Poland was exceeded. The reasonfor the exceed cobalt concentration in natural sediments was, most probably, the surface runoffs from fields and meadows in the form of fertilizers, plant protection products and the domestic waste water.

Opis:: The basic physicochemical properties such as: dry mass, pH, pseudo-total content of cadmium, lead and copper, were determined in the fresh bottom ash samples from a municipal waste incineration plant. In order to study fractional composition of the investigated heavy metals, the BCR method was used (F1 – acid soluble and exchangeable fraction, F2 – reducible fraction, F3 – oxidizable fraction, F4 – residual fraction). The average percentage of cadmium in particular fractions was as follows: F1 (37.5%) > F4 (27.2%) > F2 (25.3%) > F3 (10.0%), for lead: F4 (36.5%) > F2(27.2%) > F3(23.4%) > F1(12.9%), and in the case of copper F4(66.3%) > F3(22.1%) > F2(7.4%) > F1(4.2%). Among the studied metals, in mobile pool (F1-F3) the highest amount of cadmium was noted (72.8%); for lead it was 63.5%, and for copper 33.7% of the pseudo-total content.

Opis:: The study compared coal fly and bottom ashes for their ability to inactivate metals and lead to soil remediation. Soil was artificially contaminated with Cu, Zn, Pb and Cd at five degrees. Next, both ashes were added at five rates: 0, 0.5, 1.0, 1.5 and 2.0% and all treatments incubated. Data showed that for moderately contaminated soils, ash rates of 0.5 – 1.0% were efficient from 40 to 70% for Zn and Cd, and raised markedly to between 70 and 93% for Cu and Pb. For extremely contaminated soils, the rates of ashes at 1.0, 1.5 and 2% were much more efficient (60 – 80%). The use of fly and bottom ashes for metal inactivation and soil remediation should give greater consideration to the effect of pH and the type of heavy metals than the content of SiO2 and Al2O3. Fly ash displayed superior inactivation and remediation effects to the bottom ash.

Opis:: Roztoka Odrzańska is the last section of the Odra River estuary. Both in 1996, and in 1999 concentrations of Zn, Cu, Pb, Cd and Hg in the surface waters of Roztoka Odrzańska were within the limits for I class of purity. Maps of the heavy metal distributions in bottom sediments resemble those of TOC distribution in the < 0.20 mm fraction. Overall, 58.3% of the bottom sediments of Roztoka Odrzańska in 1996, as regards concentrations of Cd, Zn, Pb, Cu and Hg, belonged to class IV of purity; 14.6% belonged to class III; 18.8% belonged to class II and 8.3% to class I at all research stations. The excessive pollution the Roztoka Odrzańska sediments is controlled mainly by Cd and Zn concentrations and, to a much lower degree by Pb. Analyses in 1999 showed similar average concentrations of Cu, Zn and Pb, but less than half the content of cadmium. Concentrations, though, of cobalt (1.8x) and especially mercury (22.7x) were higher than the 1996 average levels. The observed concentrations fall within the concentration limits recorded in 1996 for Cu, Zn, Pb, Cd and Co, but they exceed these limits considerably for Hg.

The lake sediments were sampled in summer stagnation in the surface layer at two stands in each lake: in littoral zone and in profundal zone at maximum depth of the lake. Results of the investigations show that Zn, Cu and Mn contents in the investigated bottom sediments were low and ranged within geochemical background limits or slightly exceeded them. Presence of the metals in the sediments was spatially differential. Zn, Cu and Mn contents were significantly higher in most cases in the profundal zone of each investigated lake than they were in the litoral zone. Another factor which significantly differs the heavy metals content was level of thermal stratification.
W pracy przedstawiono występowanie cynku, miedzi i manganu w osadach dennych wybranych jezior lobeliowych, stanowiących specyficzną grupę jezior. Osady jezior pobierano w okresie stagnacji letniej z warstwy powierzchniowej, z dwóch miejsc: strefy brzegowej i w miejscu maksymalnej głębokości zbiornika. Wyniki badań zawartości cynku, miedzi i manganu w osadach badanych jezior wskazują, że stężenia tych pierwiastków były niskie i mieściły się w granicach tła geochemicznego lub nieznacznie je przekraczały. Obecność analizowanych metali w osadach była zróżnicowana przestrzennie. W większości przypadków zawartość cynku, miedzi i manganu była istotnie większa w osadach deponowanych w miejscu maksymalnej głębokości każdego jeziora w porównaniu z zawartością tych metali w osadach strefy litoralu. Czynnikiem, który istotnie różnicował zawartość analizowanych metali, była wykształcona w pełni stratyfikacja termiczna wód lub jej brak.
