The aims of proposed research regarding heay metals pollution of Šalek lakes are: (a) To determine the heavy metal levels in different compartments of the lake ecosystems (sediment, water, plankton, macrophytes, fish and birds) and to compare received data with published results from polluted and unpolluted areas. Our research will be the fist complex study regarding heavy metals in the lake ecosystems in Slovenia and moreover basis for other studies regarding anthropogenic impact on ecological balance of Šalek lakes (the impact of emissions from TEŠ, agriculture, motorway pollutants, recreations and sports activities etc.). (b) To determine the bioaccumulation factors (BAFs) for selected elements to examine the difference and bioaccumulation within lake and between different lakes (Velenje, Škale and Družmirje lake). Assessment of accumulation of trace elements through tropic chain and establish general regularities regarding distribution of HM in particular lake. (c) To determine whether the fish consumption threats human health. According to the WHO recommendation and other regulationes the maximum amount of fish consumed by adult will be defined. This part of programme is essential for performing reliable risk assessment for higher links of food web and it will help in determining trends of environmental pollution with heavy metals in aquatic ecosystems as well. (d) To complete existent biomonitoring programme of šalek lakes by using bioindicators (especially fish) for assessment of pollution with heavy metals in the lake ecosystem. According to WHO recommendations and other legislation the maximum acceptable mass of fish which is recommended to be consumed by human per week will be determined (emphasis on toxicological point of view). (e) To form a model for complex assessment of pollution with heavy metals in lakes and other water bodies.
