BIO-ACCUMULATION, ELIMINATION AND COMBINATION OF ANTIMONY BY MUSSEL, MYTILUS EDULIS
Abstract:
Bio-accumulation, elimination and combination of antimony by mussel, Mytilus edulis, were studied during a 36 day exposure to 124Sb (NO3)3. Results of the experiment show that the concentration factor of antimony in the mussel was less than 3 and the biological half time was less than 4 days. Gel chromatography of soluble cytosol fraction with sephadex G-75 indicates that most of 124Sb was bound to small molecular substances (MW<3,000) and small portion of 124Sb was bound to large molecular substances (MW>70,000).
