Description
Summary:Water quality dynamics along the Northern Dvina River is analyzed under the conditions of anthropogenic impact. Overall, river water is classified as very polluted . The cases of high and extremely high pollution are considered for different river reaches. The most widespread pollutants are organic matter and compounds of iron, copper, and zinc. The long-term average annual volumes of the inflow of individual pollutants along the river are 2–5 times the MAC. In addition, a tendency toward some improvement of river water quality downstream the river was identified with a decrease in oil products and zinc compounds.
