Abstract
Lakes, which led to environmental receiver plants, are under ever-increasing pressure from human and are the best object of study to assess the impact of anthropogenic activities on the state of eutrophication. In this assessment beyond the biological and physico-chemical conditions of the lake ecosystem, an important role is played by the impact of bottom sediments in these waters, which only allow to fully determine the level of anthropogenic pressure on the body of water. It is in the bottom sediments are accumulated pollution of the lake. Under favorable conditions in sediments accumulated dirt can again be released into the depths, acting potential source of danger for the whole ecosystem. Therefore, the aim of the study was to determine the susceptibility of selected lakes Powiat Poznański degradation and to assess the quality of these reservoirs bottom sediments.
