Accordingly, for As, Cu, Pb and Zn the respectively target values, in mg kg -1 were established: TEL – 5.9; 35.7; 35 e 123 and PEL – 17; 197; 91.3 e 315. Pb availability was mainly found in S2, suggesting the metal is bound to Fe-Mn oxides and can be released under anaerobic conditions. However, likewise Zn, Pb levels in sediments do not offer a negative risk to the aquatic organism in Admiralty Bay. Indeed, As and Cu levels were between TEL and PEL targets, indicating that adverse biological effects to aquatic organisms can be observed. Otherwise, As and Cu were mainly bound to the oxidizable fraction that is not considered to be mobile and bioavailable, but may be made mobilized by decomposition processes 132 | Annual Activity Report 2011

Disturbances are not frequent in the Antarctic environment, thus As and Cu are preferably bound to the organic matter. Conclusions Since there have been no relevant disturbances in the Antarctic environment until February of 2012, As and Cu mobilities to the local aquatic system could be suggested as negligible. Unfortunatly, the tragic event in Ferraz Station may have caused a significant antropoghenic input of chemical compounds into Admiralty Bay. Accordingly, the present study will provide substantial information to the future recovery works in the Antarctic landscape.
