Opis:: The aim of the study was to analyze the content of Ni in fractions of 1.0–0.2 mm, 0.2–0.1 mm, 0.1–0.063 mm, 0.063–0.02 mm, and <0.02 mm of river bottom sediments and plants (root, stem, leaf) of broadleaf cattail (Typha latifolia), yellow water lilies (Nuphar lutea), and cowbane (Cicuta virosa). Nickel content in bottom sediment was slightly higher than the geochemical background. The largest amounts of Ni were associated with the finest fraction, while the smallest with the thickest fraction. The highest content of this element was recorded at the point Ełk Barany, which was connected with developing industry in the city of Ełk. All of the tested plants showed greater Ni contents than the amount naturally occurring in plants. In most cases, most of Ni was associated with plant roots, and the least with leaves. It has been proven that aquatic plants can be good indicators of the aquatic environment status.

Opis:: The aim of the study was to assess the properties of bottom sediments from the inlet zone of the Rożnów Reservoir (South Poland) and to analyse the potential possibilities to use them for environmental purposes. The inlet zone of the reservoir is particularly intensely shallowed by means of the silts of the Dunajec River. A total of 20 samples were collected from the designated cross-sections. In air-dry samples of the sediments, granulometric composition, pH electrolytic conductivity (EC), sorption properties, organic carbon carbonates and macroelements content were determined. Bottom sediments from the Rożnów Reservoir indicate a great potential possibility to use them for environmental purposes (agriculture, reclamation). However, in order to fully evaluate the possibility of bottom sediment management, it is necessary to carry out an analysis of the ecological risk related to the content of heavy metals, PAHs, PCBs and to evaluate their eco-toxicity. Moreover, the main barriers to the environmental application of bottom sediments are a lack of appropriate legislation.

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 aims of the study were to assess the phytoxicity of bottom sediments collected from the Rybnik Reservoir. The water reservoir in Rybnik is located in the Silesian Voivodeship. The reservoir constitutes a part of the technological chain of Elektrownia Rybnik S.A. as a direct receiver of industrial and rainwater sewage, sewage from a water treatment plant, blowdowns from cooling towers, and as an essential source of cooling water. Sediment samples were collected with an Eckman sampler from 33 locations. The toxicity of bottom sediments was determined using the Phytotoxkit direct contact test, carried out for 3 plants: Sorghum saccharatum, Sinapis alba and Lepidium sativum. On the basis of the data received, the germination index (GI) was calculated. We found the mean value of the germination index indicated the dominance of the inhibitory effect of bottom sediments on plant growth. Sorghum saccharatum was the most sensitive to pollutants in sediments, while Lepidium sativum was the least sensitive. The Phytotoxkit is a good tool for assessing the toxicity of bottom sediments.

Opis:: One of the important environmental issues is the quality of surface waters in the world. Poland belongs to countries with a low quality of the inland waters. The sanitary condition of the five water reservoirs of south-east Poland was analyzed. Water and sediment samples were incubated on the selective and/or differential media. High concentrations of many common and pathogenic microbial indicators were shown in those samples. Those reservoirs are used by people, especially during summer. Because of the high epidemiological risk, detailed analysis of all inland waters should be performed routinely.

Opis:: The object of the study was Tyrsko Lake (area 18.6 ha, max. depth 30.4 m), located in the western part of Olsztyn (Olsztyn Lakeland). This lake is one of the clear water lakes in Olsztyn, but the progressive deterioration of water quality has been observed during recent years. The phosphorus concentration in the water-sediment interface, phosphorus fractions quantity and the amount of components which can bind this element was investigated in the upper (0–5 cm) layer of deposits. The aim of study was to analyze the potential influence of bottom sediment on the lake water quality. The obtained results revealed that the bottom sediment of Tyrsko Lake can be classified as mixed, silica-organic type, with a relatively high content of iron (over 4% Fe in d.w.). The total phosphorus content was ca. 3.5 mg P g,^-1 d.w. on average. Phosphorus in the bottom sediment was bound mainly with organic matter (NaOH-nrP fraction), which had over 50% share in TP. Highly mobile fractions (NH₄-Cl-P and BD-P) together only included ca. 5% to 7% TP. The obtained results show that the bottom sediment of Tyrsko Lake can bind phosphorus quite effectively. The calculated internal mineral phosphorus loading during summer stagnation period was 10.9 kg and it was lower that the assessed annual external phosphorus load (22.6 kg). The assessed annual phosphorus loading from both sources was still lower than the critical load according to Vollenweider criteria. However, due to the fact that the internal loading phenomenon is occurring in the lake, it should be taken into consideration that the lake water quality can deteriorate gradually during the longer time perspective. These findings should be accounted for in the future if the potential protection and restoration procedures will be developed.

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:: Aquatic ecosystems are a valuable part of natural environment. The increasing level of pollution in waters transforming biocoenoses and other adverse effects of the impact of toxic substances have contributed to the development of biological monitoring. The aim of the study was to determine the changes in contents of zinc and lead in bottom sediments and roots of aquatic plants: Phragmites australis and Acorus calamus in the river Narew. There were 14 points on the river, from where samples of bottom sediments and plant material were collected. The contents of lead and zinc were determined by means of flame atomic absorption spectrophotometry using Varian device. It was proven that bottom sediments were characterized by low contents of zinc and lead except from two sampling points: in Bondary and Narew. Achieved results of analyzes of plant material showed a slight exceeding in the case of lead. Spatial distribution of zinc and lead contents in examined roots of plants coincided with their contents in bottom sediments, which was also confirmed by statistical analysis. It was proven that aquatic plants had greater tendency for accumulation of metals than bottom sediments.

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:: Have studied lake close to neutral pH 7.75 to 7.62. Aquatic waters are order - phosphorus and nitrogen compounds. Level of activity alkaline phosphatase (APA) has an important impact on the chemical and biological processes taking place in the aquatic environment. APA belongs to a group of indicators, who tells us about the extent limitations to development of biomass in the tank water. Water of Rusalka lake were the subjects of 2008-2012 (July – September). Total alkaline phosphatase activity was determined seven times a year in these environments. A study of seasonal fluctuations showed that a maximum total alkaline phosphatase activity, both in the bottom sediment, occurred in spring (May) and summer (July, August).
