서식지에 따른 다소비 어류의 납 및 카드뮴 오염 및 위해 평가 = Contamination and Risk Assessment of Lead and Cadmium in Commonly Consumed Fishes as Affected by Habitat

다국어 초록 (Multilingual Abstract)

This study determined the concentrations of lead and cadmium in 18 species of commonly consumed fish and assessed the risk based on provisional tolerable weekly (monthly) intakes [PTW(M)I] % as affected by behavioral characteristics, such as migration and settlement. In the 18 species, the mean concentrations of lead and cadmium were higher in the 11 species of migratory fish (largehead hairtail, chub mackerel, Pacific saury, skipjack tuna, Pacific cod, anchovy, Alaska pollack, brown croaker, Japanese Spanish mackerel, yellow croaker, and Pacific herring) than in the seven demersal species (red stingray, brown sole, bastard halibut, conger eel, blackmouth angler, rockfish, and filefish). Based on the mean concentrations, the PTWI % of lead and cadmium in commonly consumed migratory fish were 1.900 and 2.986%, respectively, which were higher than the values for lead and cadmium in the commonly consumed demersal fishes (0.257 and 0.318%, respectively). The estimation of weekly (monthly) intakes and target hazard quotients for the toxic elements lead and cadmium revealed that the commonly consumed migratory and demersal fish do not pose any health risks for consumers.
