ASSESSMENT OF CURRENT GEO-ECOLOGICAL STATUS OF THE KOLA BAY BASED ON GEOCHEMICAL DATA

The data on geochemistry of modern bottom sediments of the Kola Bay are generalized. Their baseline geochemical characteristics are determined. Comparison of the data shows that modern sediments in the Kola Bay are characterized by the highest concentration of chemical elements in the northwest Russia. Geochemical zoning of the bottom of the Bay is performed, and the different regions are characterized by the content of Cu, Zn, As, Cd, Pb, Hg and hexane-soluble petroleum in the bottom sediments. These geochemical data show that intensive economic activity within the southern knee of Kola Bay and functioning of the main base of the Northern Fleet of Russia impacts on the features of distribution of chemical elements.
