Resumo

Marine sediments collected, in March/2010, close to the Comandante Ferraz Base, located in Admiralty Bay, Antarctica, were analyzed to determine arsenic (As), copper (Cu) and zinc (Zn) levels, in order to indicate the impact of the Brazilian activities in the study area.Labile concentrations of As ranged from 6 to 10 μg.kg -1 , Cu and Zn content ranged from 80 to 91 and 50 to 57 μg.kg -1 , respectively.e preliminary results indicated a slight increase of As with depth.Nonetheless, no relevant trace element inputs were observed, according to the chemical analysis adopted in the present research study.
