Abstract

A geochemical study of the Severnaya Dvina estuary was carried out during two oceanographic cruises to the White Sea. The amount and distribution of trace (Mn, Co, Cu, Ni, Pb, and Zn) and major (Al and Fe) elements in suspended particulate matter and sediments were determined. The main source of most metals studied was river discharge. A metal speciation study showed that the prevailing form is in the estuarine sediments, the minerals of which incorporated 60–99% of the total metal contents. Two zones of metal accumulation were found in sediments that were considered as local geochemical barriers within the major river–sea barrier.
