Sulfur Compounds in Bottom Sediments of Fresh-Water Basins (Mouth of the Severnaya Dvina River and Rybinsk Water Reservoir)

摘要

Composition and distribution of different forms of sulfur in bottom sediments of the Severnaya Dvina River mouth and Rybinsk water reservoir are studied. The sediments are characterized by low accumulation rate of reduced sulfur compounds and high content of organic matter. Common features of the distribution of products of hydrogen sulfide in sediments of the river and water reservoir and the specificity of anthropogenic influence in each basin are established.
