- Аннотация: The levels of accumulation of Zn, As, Cd, Be, Pb, Cr, Co, Ni, Cu, Sb, Mo, V, W, Sr, Li, Ag in the soil cover of Gusinoozersk have been determined. The largest accumulation in the city on average is characterized by Sr2.2Cu1.7 As1.6, which are supplied to soils with fly ash emissions from the Gusinoozyorskaya TPP. The soils of the city are characterized by a low hazard of HMM contamination in comparison with the accepted hygienic standards. The highest concentrations of dissolved HMMs in lake water are confined to the the mouths of the tributaries Zagustay (Sr and Mn) and Tobkhoy (Mo, Sr, Zn, Cu) in the northern part and Tsagan-Gol (Cu) in the southern part of the lake. Suspended sediments of Lake Gusinoe are depleted in all studied HMMs in comparison with regional clarkes of the lithosphere. The highest concentrations in suspended matter were found for Mn, its median content over the water area was 98.9 μg/g. In lake water, the concentrations of HMMs on average exceed the fishery MPCs by 16.2 (Mo), 2.45 (Sr), and 1.1 (Cu) times. The concentrations of these elements in suspended matter do not exceed the MPC values.
