Migration of heavy metals in water ecosystems (using the example of the Belaya River in the North-Western Caucasus)

Abstract

The results of the study of the content, spatial distribution and transformation of Fe, Mn, Pb, Zn and Cu in the system of benthal deposits of the Belaya River are presented. The results obtained were compared with the background concentrations of metals, which allow us to estimate the anthropogenic component. It has been established that discharges from industries cause increased concentrations of metals in benthal deposits in certain areas of the Belaya River basin.
