Arsenic and heavy metals in the bottom sediments of the Balaklava Bay (Black Sea)

Arsenic and heavy metals in the bottom sediments of the Balaklava Bay (Black Sea) We present the results of investigation of the contents of metals (As, Cr, Co, Cu, Ni, Pb, Zn, V, Sr, Mn, Ti, and Fe) in the bottom sediments of the Balaklava Bay (Black Sea) carried out in July 2005. It is shown that the pollution of the bottom sediments with metals has a polyelemental character. We establish the specific features of changes in the contents of the analyzed elements and localize the sources of their appearance in the ecosystem. On the basis of the results of evaluation of the intensity of technogenic action upon the marine medium, we determine a group of toxic elements (As, Cr, Cu, Pb, and Zn) accumulated in the bottom sediments of the bay in amounts significantly exceeding the background values typical of sediments of the Black Sea shelf. The comparative analysis of the degrees of pollution of the bay and some other coastal water areas with metals is performed. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Physical Oceanography Springer Journals

Abstract

We present the results of investigation of the contents of metals (As, Cr, Co, Cu, Ni, Pb, Zn, V, Sr, Mn, Ti, and Fe) in the bottom sediments of the Balaklava Bay (Black Sea) carried out in July 2005. It is shown that the pollution of the bottom sediments with metals has a polyelemental character. We establish the specific features of changes in the contents of the analyzed elements and localize the sources of their appearance in the ecosystem. On the basis of the results of evaluation of the intensity of technogenic action upon the marine medium, we determine a group of toxic elements (As, Cr, Cu, Pb, and Zn) accumulated in the bottom sediments of the bay in amounts significantly exceeding the background values typical of sediments of the Black Sea shelf. The comparative analysis of the degrees of pollution of the bay and some other coastal water areas with metals is performed.
