ENVIRONMENTAL ASSESSMENT OF HEAVY METALS CONTENT IN SOIL-PLANT SYSTEM

Abstract

The content of heavy metals (Ag, Cd, Sn, Cs, Ba, La, Rb, Sr, Mn, Fe, Cu, Zn) has been determinate in the soil-plant system: cambic chernozem - winter wheat. It was found that the amount of Ag, Sb, Sn and Ba are accumulating in soil, exceeds the admissible concentration limit. In winter wheat, the content of Cd, Fe and Zn exceed the maximum admissible concentrations. The Rb, Mn, Zn accumulates in the winter wheat grains, and Fe and Cu – in the vegetal organs of wheat.
