Abstract

It was shown that carbon sequestrating role of phytomass decreases almost 30 times along the pollution gradient. The processes of copper and nickel release during decomposition and their consumption during production synthesis are unbalanced. Dead plant material serves as a sorption, sedimentation and mechanical barrier where heavy metals and sulfur concentrate.
