This study was concentrated that the contents of heavy metals were estimated from 782 samples of sold fisheries in Seoul(33 species in fishes, 15 in bivalves, 12 in crustaceans and 10 in others) by Atomic Absorption Spectrometer. The contents of As, Cd and Pb [minimum-maximum (mean)] were N.D.-0.162 mg/kg(0.021), 0.001-0.120 mg/kg(0.014) and 0.015-0.499 mg/kg(0.111) in fishes, 0.003-0.311 mg/kg(0.052), N.D.-1.905 mg/kg(0.182) and 0.013-0.462 mg/kg(0.138) in bivalves, N.D.-0.328 mg/kg(0.042), 0.002-1.113 mg/kg(0.079) and 0.006-0.510 mg/kg(0.109) in crustaceans, N.D.-0.181 mg/kg(0.024), 0.001-0.214 mg/kg(0.033) and 0.010-V0.877 mg/kg(0.118) in others respectively, bivalves were the highest than others. The average weekly intakes of three metals from sold fisheries took about 1.4-26.4% of PTWI (provisional tolerable weekly intakes) that FAO/WHO Joint Food Additive and Contaminants Committee had set to evaluate their safety.
