한국의 TBT 오염과 TBT가 해양생물에 미치는 영향

Abstract

TBT-based antifouling paints were banned since March 2000 in Korea, though Korea needs large quantities of them for its shipping industry that is one of the largest in the world. Organotins were studied in the coast of Korea, in order to assess the exposure of marine organisms to butyl- and phenyltin compounds and to understand the toxic effects of these compounds to marine organisms. Butyltin compounds (BTs) were detected from the mussel and oyster samples collected from 67 sites on the coast of Korea, where phenyltin compounds (PTs) were below detection limits at 26 out of 67 sites. Overall range of tributyltin (TBT) and triphenyltin (TPT) concentrations were 48 to 2800 ng/g and <3 to 1820 ng/g, respectively. The mean TBT concentration in bivalves was 3.5 times higher than that of TPT.
