Geochemistry of Suspended Particulate Matter in the Volga River Marginal Filter

Abstract

The first data on a long-term study of the Volga River marginal filter are reported. The concentrations of suspended particulate matter, particulate chemical elements, and trace elements are considered. The ratios of suspended particulate matter enrichment in chemical elements in relation to the upper lithosphere are calculated, as well as their interrelations at different stages of the marginal filter. It is shown that sedimentary material delivered to the sea with river runoff changes radically, both quantitatively and qualitatively.
