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. The geochemical data suggest that most of the metals found in Potter Cove constitute a redistribution of autochthonous materials within the ecosystem. Therefore, the metal concentrations can be considered to be present at natural background levels in surface sediments.
采用原子吸收光谱法测定了从南极洲25 de Mayo岛（乔治王岛）的波特湾及其流域采集的表层沉积物中铅、镉、铜、铬、铁、锰和锌的浓度。所得结果用于确定该海湾中金属的面积和垂直分布以及这些金属进入该环境的潜在来源。地球化学数据表明，在波特湾发现的大多数金属是生态系统内本地物质的重新分布。因此，表层沉积物中的金属浓度可被视为处于自然背景水平。
