Mercury, cadmium and lead in black scabbardfish (Aphanopus carbo Lowe, 1839) from mainland Portugal and the Azores and Madeira archipelagos
Total mercury (THg), cadmium (Cd) and lead (Pb) concentrations were investigated in muscle, liver and gonad tissue of black scabbardfish (Aphanopus carbo) from the southern northeast Atlantic at three Portuguese locations: the mainland and the archipelagos of the Azores and Madeira.
