영문 초록

This study was performed to investigate the heavy metal contents and distribution in bioorganisms from the estuary area of Mankyeong-Dongjin river. In paddy plant, the average contents of heavy metals were in order of Zn>Cu>Pb>Cr>Cd in all parts. Those of Cd, Cr, Pb and Cu were all highest in the leaf while lowest in the brown rice. The average content of Zn was almost similar in all parts. In the dried muscular parts of shellfish, the average contents of heavy metals were in the range of 1.06~1.95 mg/kg for Cd, 2.93~4.98 mg/kg for Cr, 0.90~1.17 mg/kg for Pb, 8.41~18.58 mg/kg for Cu and 29.81~67.31 for Zn, respectively, In fish(Acanthogobius hasta), the average contents of heavy metals in the dried body parts were in the range of 0.05~0.43 mg/kg for Cd, 0.65~4.59 mg/kg for Cr, 1.01~4.75 mg/kg for Pb and 1.34~4.19 mg/kg for Cu, with high accumulation in bone and head overally.
