DISTRIBUTION OF HEAVY METALS IN SURFACE SEDIMENTS FROM AN ANTARCTIC MARINE ECOSYSTEM

摘要

The concentrations of lead, cadmium, copper, chromium, iron, manganese and zinc in surface sediments collected from Potter Cove, in the 25 de Mayo Island(King George Island), Antarctica, and its drainage basin, were measured by atomic absorption spectroscopy. The obtained Results were use to determine the areal and vertical distribution of the metals of in the Cove and Potential sources of these metals to this environment.
