In Antarctica the main local source of metal and metalloid is related to the activities of research stations. In order to verify the contribution of the Comandante Ferraz Brazilian Antarctica Station (EACF- Portuguese acronym, in continuity) in the accumulation of these elements, and to supply baseline values to allow future monitoring, the concentration of Ag, As, Cd, Cu, Ni, Pb and Zn was measured in twelve benthic Antarctic species (Desmarestia sp, Himantothallus grandifolius, Laternula elliptica, Yoldia eightsi, Amphioplus acutus, Bovalia gigantea, Gondogeneia antarctica, Sterechinus neumayeri, Nacella concinna, Paraserolis polita, Parborlasia corrugatus and Glyptonotus antarcticus). A wide variation in metal content was observed depending on the species and the element. These concentrations were usually lower than those of other Antarctic areas, not indicating relevant anthropogenic impacts of EACF. However, considering the serious fire incident that occurred at the end of last summer (February/2012), and that relevant measures of heavy metals (such as Pb, Cd, and Zn) are released in this kind of event, this data, and the associated methodology, attains particular importance, due to their potential to enlighten the extension of this impact, as well as, the success of any recuperation strategy. Keywords: Antarctica, bioaccumulation, metal, metalloid Introduction The bioaccumulation of trace elements is defined as the uptake of a chemical by an organism from the abiotic and/ or biotic (food) environment (Gray, 2002), and is a widely observed process (e.g. Santos et al., 2006; Farías et al., 2007; Gray et al., 2008; Grotti et al., 2008). For metals and metalloids the bioaccumulation may be the result of natural sources, since these elements are constituents of any ecosystem (Grotti et al., 2008). In Antarctica, like other remote regions of the Earth, the natural concentration of metals and metalloids in abiotic matrices (snow, ice, soil, sediment and air) of most areas are generally within or lower than the observed values of other polar areas, being considered as background levels (Sanchez-Hernandez, 2000). However, near the research stations a lower but continuous kind of contamination is observed (Vodopivez & Curtosi, 1998), directly linked with activities such as garbage incineration, use of paints, fuel usage and sewage (Santos et al., 2004). The result is an increased concentration of both organic and inorganic contaminants, and their impacts are obviously linked with the increasing presence Science Highlights - Thematic Area 3 | 135
