Clarks of metals in soils and alluvial deposits of Kuibyshev reservoir island landscapes

Abstract

The content and distribution of metals (Pb, Cu, Ni, Zn, Cr, Mn) in soils and alluvial deposits of the islands of Kuibyshev reservoir are studied on the base of geochemical approach- ment. The main sources of metals in islands ecosystems are discussed. The noticed regional difference in metals contents in soils between Volga and Kama islands is due to rock composition, grain sixe of deposits and soil formation regimes.
