“…Deposited organic matter comprises fragments of dead organisms and organic suspensions, and it is formed through the precipitation and coagulation of dissolved organic substances. Its content in the surface layer of bottom deposits is determined by the amount of material produced in the trophogenic zone, the quantity of allochthonous matter and sedimentation rate [12]. The average organic matter content of Lake Sunia was 24.8±4.9% d.m.…”

Abstract:Various elements are accumulated in bottom deposits in concentrations that significantly exceed the levels observed in lake water. Under certain conditions, this can lead to secondary contamination of water, posing a threat to aquatic organisms. The aim of this study was to evaluate the spatial distribution of Pb, Zn and Cr pollutants in the bottom deposits of Lake Sunia. The investigated water body is situated in the Olsztyn Lakeland (western part of the Masurian Lakeland), approximately 30 km north of the city of Olsztyn, in the municipality of Swiatki. The lake has a total area of 111.6 ha and a maximum depth of 8.8 m. The inflow to and the outflow from lake are situated in its south-western and north-western part, respectively. The lake features a bay which is separated from the main water body by a shallow zone. Its catchment area comprises mainly agricultural land. The total area of supply of lake is 450 ha of which inflow catchment area is 70 ha. Most of the catchment area is agricultural land (91%), and in particular arable land, the rest of the area (5%) are the barren, and trees (4%). In the area of the lake is dominated by power-sandy loam soil in the passing sands and clay loam strong little sandy. In terms of particle size are a summary of the soil that is difficult permeable to water and nutrients. Taking into account the valuation of soil classification in the vast quantities of soil are included in the class IVa, IIIa and IIIb. The average content of organic matter in the lake was determined at 24%. Significant accumulation of organic matter results from intense inflow of biogenic substances from farmed areas in the catchment. The average concentrations of trace elements in the analyzed water body were arranged in the following series: Cr < Pb < Zn, and their ratios were determined at 8.1 < 22.9 < 45.2. Higher levels of heavy metals were observed in the profundal zone, whereas lower concentrations of the analyzed elements were noted in littoral zone sediments.Keywords: anthropogenic pressure, bottom deposits, heavy metals All water reservoirs have their bottom, which settle on the organic and inorganic suspensions. They form a bottom deposits characteristic for catchment and morphological feature [1]. The settlement of allochthonous material formed outside the sedimentation zone and autochthonous material created at the place of sedimentation leads to the formation of bottom sediments in water bodies [2]. The content of chemical compounds in sediments is determined by the type of bed rock forming lake catchments as well as land use patterns in the catchment area. Rock strata constitute a point of reference (geochemical background)

The study presents some authors’ experimental results for determination of some quality indicators (few general, specific and toxic physical-chemical indicators) analyzed at the beginning of summer season (June, 2013), in three control sections of Siret River in Pascani town area (i.e. Lunca-Pascani entrance, 1 km-upstream, and 1 km-downstream of Pascani bridge, respectively). The real pollution status of Siret River in Pascani town area is also estimated by the global pollution index (I* GP), and corresponds to values between 3.215-3.891 indicating ‘an aquatic environment modified by domestic and economic activities alongside the river with generation of stress effect against life forms’.
