“…Surface sediments were collected from both studied lakes in 2002. The cores were analysed for acidification over the last 150 years (Sienkiewicz et al 2006). Based on 210 Pb dating, the diatom-inferred pH values confirm that an increase of acidity began in the 1970s in the studied lakes.…”

Past environmental changes in mountain lakes can be reconstructed with the use of subfossil diatoms from post-glacial sediments. This study applied such an analysis to two mountain lakes in the Sudetes Mts. in Poland: Mały Staw (MS) and Wielki Staw (WS). Cores 882 cm long (MS) and 1100 cm long (WS) taken from the centre of each lake in 1982 were used to study the long-term acidification history of these lakes. Changes in vegetation indicate that the initial phase of MS started at the end of the Pleistocene. WS sediments began to accumulate shortly after that, at the beginning of the Holocene. The majority of the diatom assemblages are typical of oligotrophic acidic lakes located in alpine and arctic regions. A pH reconstruction based on diatoms (DI-pH) showed long-term acidification dating to almost the beginning of the lakes' existence. Natural acidification began after the deglaciation, and the most intensive acidification continued to the end of the mid-Holocene. Through the whole period studied, pH decreased by 1.4 in MS and 0.9 in WS. After a period of relatively stable lake water pH, it decreased rapidly during the last few decades of the 20 th century, due to anthropogenic pollution: pH declined by 0.7 in MS and 0.3 in WS. Mały Staw, being shallower, smaller, and with a larger drainage basin than Wielki Staw, is more sensitive to acid deposition; this accounts for the difference in pH.

“…First of all, the increased mobility of the Cd deposited in sediments poses a geoecological hazard as the environment becomes increasingly acidified, which has been identified for many years (Newell and Skjelkvale 1997;Chen et al 2004;Sienkiewicz et al 2006;Stuchlik et al 2006). The high degree of bioaccumulation and the possibility that Cd could become mobile in an acidic environment as a result of human activities mean that there is a risk of environmental contamination, and the safe operation of reservoirs could be affected, including difficulties with sourcing water for municipal purposes and the mortality of fish and other aquatic organisms (Jankowski et al 2002).…”

Purpose Cadmium (Cd) is considered a toxic element and its concentrations are relevant to human health and the environment. Therefore, the purpose of the study was to determine the extent to which the bottom sediments of water bodies (artificial lakes and ponds) in the Silesian Upland in southern Poland are contaminated with Cd; an attempt was also made to determine the factors that condition spatial differences in the concentration of this element between individual water bodies in the region. Materials and methods Measurements of the Cd content in bottom sediments were carried out in 35 water bodies in southern Poland in 2011 and 2012. Depending on the surface area and morphometric characteristics, from two to nine samples representative in terms of sediment thickness were collected in each water body. Cadmium concentrations were determined for 92 0.25 g aliquots using the TD-ICP method. Results and discussion Cadmium content in all samples (0.7-580.0 mg kg ) and, with a few exceptions, was also higher than the preindustrial concentration (1.0 mg kg ) as the baseline for the geoaccumulation index (I geo ), the sediments examined can be classified as extremely and heavily contaminated (and moderately contaminated in a small number of cases). The assessment of sediment quality based on I geo, with the regional geochemical background (2.5 mg kg −1 ) adopted as the baseline, results in non-contaminated and moderately contaminated sediments being dominant with a far smaller number of heavily and extremely contaminated ones. Conclusions In the case of several water bodies, Cd concentrations were at record levels that have not been found anywhere else in the world. On the basis of the I geo , sediments of varying quality were found-from virtually uncontaminated to extremely contaminated. The I geo index as an indicator of the quality of bottom sediments is a measure that requires careful interpretation, especially when different concentration levels regarded as natural are used for determining its value.

“…Lake sediments contain a record of climatic and ecological changes taking place during the time of their deposition. These changes are recorded as vertical variations of physical and chemical properties (Eskola & Peuraniemi, 2008) and changes in species composition of plant and animal remains (Milecka & Szeroczyńska, 2005;Sienkiewicz et al, 2006;. Most changes are connected with natural processes, such as aging of the lake and climatic changes; however, these natural processes are often interrupted by human-induced changes, in particular, overloading of the system by biogenic substances (Kozerski et al, 1999;Reed et al, 2008).…”

Short sediment cores from two small oxbow lakes located in the Vistula valley near Warsaw (Poland) were analysed for chemical composition and zooplankton (Cladocera) remains. The results of these analyses were evaluated using ordination techniques and the results were used to reconstruct the history of human impact of the lakes. The cores were dated using the 210 Pb method. These analyses show that the collected sediments (60 cm-and 67 cm-long-cores) were deposited during the last 150-200 years. Cladocera assemblages were different in the two lakes; however, Bosmina longirostris was dominant among subfossil Cladocera species in both lakes. The presence of this species indicates the high trophic state of the lakes. Changes in Cladocera species composition suggest that a significant increase in the lakes' trophic levels has occurred since the 1920s. The change could be related to the construction of flood dikes along the river Vistula, the isolation of the studied lakes from the river, changes in land use, or some combination of these factors. The chemical composition of sediments, particularly the increase in phosphorus and sulphur concentrations, confirms that the construction of dikes against flood was the major factor inducing eutrophication of the oxbow lakes. This study shows that the Warsaw small water bodies are especially sensitive to local disturbances caused by human activity, mainly water management, land use changes and agriculture.
