Abstract

Amur pollution is considered as a function of the content of soluble and suspended forms of chemical compounds in river water. It was revealed that low-mobile chemical elements (Fe, Al, Cd, Zn, Cu, Pb) migrate both in the composition of large organic colloids (0.45–1.0 μm) and in the composition of soluble complex salts. Their concentrations in the river bed are controlled by industrial, urban and agricultural wastewater. The processes of redistribution of elements between their colloidal and soluble forms are determined by the activity of channel processes, the composition of bog waters, and flow turbulence. High floods 2019–2021 in the absence of man-made accidents, they contributed to a gradual decrease in the concentration of pollutants and stabilization of water quality in the Amur.
