AbstractThe mean concentrations of trace elements were determined in the bottoms of open water reservoirs in the western part of the Orenburg Region. The content of chromium was found to exceed the maximum permissible concentration by about 5 times, that of zinc and nickel complies with the clarke; that of copper was nearly 2 times less than the clarke, that of cobalt and vanadium is nearly 1.5 times less. The concentrations of trace elements in the bottoms were compared with those in soil, portable water, and snow cover in order to elucidate possible sources of origin.
