This study was performed to estimate the heavy metal concentrations(Pb, Cd, Hg,
and As) and analyze risks based on 103 samples of fishery products. In this paper,
inductively coupled plasma-mass spectrometry(ICP-MS) measurements were used to
determine the concentration of lead, cadmium, and arsenic. The concentration of mercury
was determined by the mercury analyzer using a Hydra II C. The mean concentration
of lead, cadmium, mercury and arsenic in canned foods were 0.015 mg/kg, 0.041 mg/kg,
0.052 mg/kg and 1.739 mg/kg, respectively, which were significantly higher than those of
chilled and frozen foods(t-test, p < 0.05). The mean concentration of mercury was 0.067
mg/kg, and the concentration was the highest in processed marine fish products. Arsenic
was detected in marine fish(1.843 mg/kg) and other fishery products(1.876 mg/kg), but
arsenic is generally present in the form of organic arsenic compounds in marine
environments and is found to be harmless to humans. The weekl
