Environmental and Geochemical Assessment of Bottom Sediment Pollution (Approaches, Monitoring, Utilization)

Abstract

The results of ecological and geochemical assessment of the state of bottom sediments of small rivers in the city of Berezniki (Perm region) are presented, and the issues of environmental monitoring of small rivers of Verkhnekamie are identified. A comprehensive assessment of bottom sediment contamination is carried out. Their unsatisfactory condition in terms of the heavy metals content (Ni, Cu, Zn, Pb, Cd, Hg) and As was noted. Possible environmental actions for the disposal of such sediments are analyzed. It is concluded that it is advisable to carry out on-site remediation or dispose of sediments at specialized landfills followed by recycling.
