Contents of heavy metals in sea waters, sediments, fishes, and shellfishes from Kunsan Changhang coastal areas were investigated. Average contents of heavy metals in sea water were Pb 2.35, Cd 0.52, Cu 2.09, Zn 13.65 and $Hg\;0.24\;{\mu}g/l$. Average contents of heavy metals in sediments were Pb 19.49, Cd 0.15, Cu 9.31, Zn 20.07 mg/kg, and $Hg{\;}13.6{\;}{\mu}g/l$. Average contents of Pb, Cd, Cu, Zn, and Hg in .Acantogobius hasta were 1.08, 0.05, 2.24, 58.14, and 0.151 mg/kg and those in Mugil cephalus were 1.63, 0.05, 1.51, 32.69, and 0.065 mg/kg. Accumulation ratios of Pb and Cu in Acantogobius hasta were similar to Mugil cephalus but accumulation ratios of Zn and Hg in Acantogobius hasta were higher 2 times than in Mugil cephalus. Average contents of Pb, Cd, Cu, Zn, and Hg in Cyclina sinensis were 1.03, 1.23, 6.83, 75.83, and 0.071 mg/kg and those in Ruditapes philippinarum were 0.93, 0.86, 5.90, 52.16, and 0.074 mg/kg. Accumulation ratios of heavy metals in shellfishes were in the order of Cu>Cd>Zn>Pb>Hg, irrespective of shellfishes kind.
