Pollution of water and bottom sediments of the Polar Front area in the Barents Sea with heavy metals
Pollution of the Barents Sea water and bottom sediments in the Polar Front area with heavy metals including Cu, Ni, Co, Cd, Hg, Zn, Pb and Cr has been considered based on the long-term data. The existence of a voluminous own database of Knipovich Polar Research Institute of Marine Fisheries and Ocea...
