Arsenic content in five sediment profiles from Admiralty Bay, King George Island, Antarctica

Arsenic, copper and zinc in marine sediments from the proximity of the brazilian­antarctic base, Admiralty Bay, King George Island, ­Antartica

“…Likewise previous work (Ribeiro et al, 2010), the results indicated a slight decrease of As with depth (Figure 1), suggesting that the human activities may be contributing to the As enrichment in the study site. e data set suggests the natural sources are the main inputs for Cu and Zn …”

“…A recent study with ve sediment pro les from the Admiralty Bay has suggested a slight increase of As levels, since 1985. According to the authors, the increase of As content may be associated with the Brazilian activities in the bay (Ribeiro et al, 2010). Otherwise, there is no evidence of relevant impact to the ecosystem due to trace element sources in the region (Santos et al, 2005;Martins et al, 2005).…”
