“…Lead is likely to be delivered to the bay as a result of areal flow from the nearby morainic hills. The increased Pb content in samples taken from the littoral zone, higher by 54.4% than in the profundal zone, can be associated with the proximity of the sampling sites to provincial roads with relatively high traffic, as reported by Skorbiłowicz and Skorbiłowicz [42]. In line with European Union law, leaded gasoline has not been used in Poland since 2005, but lead could have been accumulating in sediments for a long time.…”

River-lake systems most often behave as hydrographic units, which undergo complex interactions, especially in the contact zone. One such interaction pertains to the role of a river in the dispersal of trace elements carried into and out of a lake. In this study, we aimed to assess the impact of rivers on the accumulation of heavy metals in bottom sediments of natural lakes comprised in postglacial river-lake systems. The results showed that a river flowing through a lake is a key factor responsible for the input of the majority of available fraction of heavy metals (Zn, Mn, Cd and Ni) into the water body and for their accumulation along the flow of river water in the lake. The origin of other accumulated elements were the linear and point sources in catchments. In turn, the Pb content was associated with the location of roads in the direct catchment, while the sediment structure (especially size of fraction and density) could have affected the accumulation of Cr and Zn, which indicated correlations between these metals and fine fraction. Our results suggest that lakes act as filters and contribute to the self-purification of water that flows through them. As a result, the content of most metals in lake sediments showed a decrease by approx. 75% between the upstream (inflow) and downstream (outflow) sections. The increased content of two metals only, such as chromium and cadmium (higher by 2.0 and 2.5 times, respectively, after passing through the lake), was due to the correlation of the metals with fine sand. Both the content and distribution pattern of heavy metals in lake sediments are indicative of the natural response of aquatic ecosystems to environmental stressors, such as pollutant import with river water or climate change. The complex elements creating the water ecosystem of each lake can counteract stress by temporarily removing pollutants such as toxic metals form circulation and depositing them mostly around the delta.

“…As a result, micropollutant concentrations in water do not reflect the extent to which they pollute the entire aquatic geosystem. A significant proportion of micropollutants are accumulated in bottom sediments -river, reservoir or lake sediments (Loska and Wiechuła 2003;Yang and Rose, 2005;Ghrefat and Yusuf, 2006;Skorbiłowicz and Skorbiłowicz, 2011). This is particularly true of heavy metals.…”

The chemical composition of the bottom sediment, and more particularly the heavy metals content, reflects human developments and impacts on the catchment and reservoir's natural environment. The bottom sediments of the reservoir retained by the Irkutsk Dam have been analysed. The reservoir is mainly supplied by water from Lake Baikal. The following amounts of heavy metals have been found in the sediment samples analysed: cadmium -below detection threshold (<0.5 ppm), cobalt -from 16 ppm to 23 ppm, chromium -from 104 ppm to 243 ppm, copper -from 21 ppm to 35 ppm, mercury -below detection threshold (<1 ppm), molybdenumbelow detection threshold (<2 ppm), nickel -from 44 ppm to 80 ppm, lead -from 13 ppm to 17 ppm and zinc -from 73 ppm to 98 ppm. Cobalt, chromium and nickel contents exceeded the natural geochemical background level. This may indicates anthropogenic impacts on the reservoir's geosystem.Reference to this paper should be made as follows: Jagus, A., Khak, V., Rzetala, M.A. and Rzetala, M.

“…The studies conducted by other authors in Poland (9,21,28), obtained values exceeding the geochemical background and PEL. In river sediments, the mean values of arsenic were lower than the permissible background (5 mg/kg), but the maximum value of arsenic (14.46 mg/kg) in the sediment of the Vistula near Cracow indicates a higher arsenic contamination in comparison with other regions.…”

“…In contrast, lead, cadmium, mercury, or arsenic can be toxic, even in trace amounts. The concentrations of these elements in fish and sediments are the subject of scientific discussion in many publications (5,9,10,18,22,24,25,(27)(28)(29). Lead and cadmium are widespread in the environment.…”

Samples for analysis were collected from 10 areas, including the major Polish rivers and lakes, with different sources of environmental pollution (industrial, municipal, and farming). The materials was taken from the lakes of Mazury, located in a non-industrialised region, from the Brda River, an area impacted by pig farms, from the lakes of Lipczyno Wielkie/Pomerania, from the Wkra River, an area impacted by poultry farms, from the Dunajec River at the Roznowski Reservoir, from the Vistula River at Cracow and Warsaw, from the Odra River at Wroclaw and the Warta River estuary, and also from Rybnik Power Station Reservoir. Concentrations of Pb, Cd, Hg, and As were analysed in 397 fish muscle and 128 sediment samples using an atomic absorption spectrometry technique. The analytical procedures were covered by a quality assurance programme. It was demonstrated that the average concentrations of lead, cadmium, and arsenic in fish were in the low hundredths and thousandths of a mg/kg and never exceeded permitted limits established for food. Higher values of these elements were found in fish from bodies of water located in the zone of influence of large urban agglomerations, especially the Cracow region. High concentrations of lead and cadmium were also found in Vistula River sediments near Cracow, where the maximum values were 134.10 mg/kg and 21.24 mg/kg dry weight for lead and cadmium respectively. The average concentration of mercury in a predatory fish muscle (0.179 mg/kg) was almost twice as high as in the omnivorous fish (0.103 mg/kg). Only a single fish sample exceeded the maximum limit for this metal (0.50 mg/kg) and did not present a risk to consumers' health.
