There are few studies on toxic metals in crustaceans available in Korea. Therefore, this study was conducted to estimate contents of toxic metals in crustaceans (n = 58). Samples were digested with acids and analyzed by inductively coupled plasma spectrometer (ICP) or atomic absorption spectrometer (AAS) for lead (Pb), cadmium (Cd), and arsenic (As). Mercury (Hg) contents were determined using mercury analyzer. Toxic metal contents [minimum-maximum (mean), mg/kg] in crustaceans were as follows; Hg 0.004-0.28 (0.06), Pb ND-0.31 (0,03), Cd 0.003-0.92 (0.14), and As 0.01-35.9 (6.63). Our results demonstrated that metal contents in crustaceans on Korean markets were similar to those reported in other countries. Our average weekly intakes of Pb, Cd, andHg from crustaceans were lower than 1% of Provisional Tolerable Weekly Intakes (PTWI) set by Joint FAO/WHO Expert Committee for food safety evaluation.
