Butyltins were determined in seawater, sediments, and mussels (Mytilus edulis) collected from Busan Harbor, the largest commercial harbor in Korea, to assess the contamination status and the effectiveness of tributylin (TBT) restriction. TBT concentrations were found to be 7.6 +/- 8.3 ng Sn/L in seawater, 387 +/- 606 ng Sn/g dry weight (wt) in sediments, and 322 +/- 167 ng Sn/g dry wt in mussels, and are comparable to those in the largest harbors worldwide. TBT levels were highest at locations near shipyards and related facilities. Busan Harbor was characterized by the long-term history of butyltin contamination, based on the lowered TBT/DBT ratios in environmental matrices. The temporal trend of TBT levels decreased significantly in seawater and mussels from 2002 to 2007, probably as a consequence of the legislative action in Korea (MOE Regulation 154/2000). However, TBT in sediments did not show any trend, suggesting a long half-life for TBT, about 17 years, in sediments.
在韩国最大的商业港口釜山港采集的海水、沉积物和贻贝（Mytilus edulis）中检测到了丁基锡，以评估污染状况和三丁基锡（TBT）限制的有效性。海水中 TBT 的浓度为 7.6±8.3ng Sn/L，沉积物中为 387±606ng Sn/g 干重（wt），贻贝中为 322±167ng Sn/g 干重，与世界上最大的港口相当。在靠近造船厂和相关设施的地方，TBT 浓度最高。釜山港的特点是丁基锡污染具有长期历史，这反映在环境基质中 TBT/DBT 比值降低。2002 年至 2007 年间，海水中和贻贝中的 TBT 水平显著下降，这可能是由于韩国的立法行动（MOE 法规 154/2000）。然而，沉积物中的 TBT 没有显示出任何趋势，表明 TBT 在沉积物中的半衰期约为 17 年。
