摘要：

Bottom sediments of the reservoirs are the active storage of various contaminants. They represent a potential source of the secondary pollution of an aquatic environment. Exchange processes by heavy metals and organic compounds in the sediment/water system in the presence of humic substances were investigated under model experimental conditions. The studies have been also made aimed at the content and composition of dissolved organic matter, speciation of available metals in the pore solution and in the aqueous phase contacting with silt. Both oxygen deficit and complexation with humic substances caused increase of metal, protein and carbohydrate concentrations in the water medium.
