| Tributyltn, triphenyltin and their degradation products were quantitatively determined in sediments, seawater, and oysters (Crassostrea gigas) collected from Okpo Bay, Korea where a huge shipyard was located. The concentrations of TBT in sediment and oyster were in the range of 5¡2,050 ng/g and 387¡1,190 ng/g (astin on a dry weight basis), respectively. In seawater, it ranged from 19 to 84 ng/§¤ The distribution of TBT compound showed negative gradient from inner to outer bay, which indicates that the shipyard is the point source of TBT contamination in the bay. The contribution of TBT to butyltin concentration in sediment was above 57%. The pattern of TBT distribution was influenced by waterbreak transected the bay. TPhT concentration in oyster ranged from nd (not detected) to 52 ng Sn/g dry wt., whereas that in sediment and seawater was below detection limit. The biological concentration factor (BCF) in oyster was 1.1¡¿10©ù. |
