INFLUENCE OF FLOODS ON THE PROCESSES OF CONCENTRATION AND MIGRATION OF CHEMICAL COMPOUNDS IN THE AMUR RIVER

A.N. Makhinov, A.F. Makhinova

Аннотация


The concentration of chemical elements  in the Amur riverbed is considered as a function of the state of their soluble and suspended forms. It was revealed that slow-moving chemical elements (Fe, Al, Cd, Zn, Cu, Pb) migrate both in large organic colloids (0.45–1.0 μm) and in soluble complex salts. The role of organic matter in the redistribution of elements between their suspended and soluble forms has been studied. The authors describe the mechanisms of migration of chemical compounds.
