Assessment of Self-Cleaning from Heavy Metal Contamination of the European Territory of Russia Northern River Ecosystem
Abstract Self-purification from heavy metals (Cu, Ni, Pb, Zn, Cd and Cr) was assessed in the estuary area of the one of the largest river ecosystems in the European territory of Russia – the Northern Dvina River estuary. The conditional degree of self-purification of river waters and bottom sediment...
