Summary: | Sea urchins are marine and benthic invertebrates, many of them sessile or with reduced mobility. The species Sterechinus neumayeri (Meissner, 1900) is the most abundant in shallow Antarctic seawater. Sea urchins have been frequently applied for ecotoxicological tests, but few studies have assessed these organisms as biomonitors. Comandante Ferraz Antartic Station (FS), part of the Brazilian Antarctic Base located on King George Island, in Admiralty Bay, was chosen for this study, and two sampling sites were chosen for this purpose: Botany as control site and near to the waste disposal of Ferraz Station which was almost destroyed by fire occurred in 2012, consuming about of 70% of the facilities. The micronutrients and some trace element concentrations were determined by Instrumental Neutron Activation Analysis (INAA). Results obtained for Br, Co, Cr, Cs, K, Se and Zn presented a higher concentration in the Comandante Ferraz Station. Elements such As, Ba, Fe, Na, Rb and Sc showed no significant difference between sites. Exploratory PCA results showed that the two regions were separated by Br, Cr, Cs, K, Se and Zn. Results indicate the possibility of applying this organism for biomonitoring purposes for metals Cr, Zn and semi-metal Se. |
