The concentrations of cadmium, cobalt, chromium, copper, iron, manganese, nickel, lead, and zinc were determined by ICP-AES in muscles and livers of eight fish species sampled from the Aegean and Mediterranean seas of Turkey. Iron showed the highest levels, followed by Zinc in examined tissues of all fish species. Metal concentrations in edible parts of fish species were 0.03-0.37 mg kg(-1) for cadmium, 0.02-0.42 mg kg(-1) for cobalt, 0.15-1.78 mg kg(-1) for chromium, 0.17-1.11 mg kg(-1) for copper, 11.0-33.4 mg kg(-1) for iron, 0.02-0.89 mg kg(-1) for manganese, 0.22-4.03 mg kg(-1) for nickel, 0.22-0.64 mg kg(-1) for lead, and 2.88-10.9 mg kg(-1) for zinc, respectively. All metal concentrations in livers were higher than those in muscles. In some stations, cadmium, chromium, cobalt, and lead concentrations in both muscles and livers of the examined species were higher than permissible safety levels for human uses.
