摘要：
Data on river water quality and pollution level have been analyzed to show that the Northern Dvina basin water is characterized by class 3 quality (categories 3. and 3B, i.e., polluted and very polluted), with copper, zinc, and iron compounds and oxidation-resistant organic matter as critical pollution indicators. Special attention should be paid to these substances since their high concentration considerably decreases the water quality in the catchment area.
