Mussels (Mytilus galloprovincialis) were transplanted to seven stations around a large shipyard for 126 days to evaluate tributyltin (TBT) contamination. Although the application of TBT-based paints to ships is totally banned in Korea, butyltin compounds were found to accumulate in mussels following transplantation. Concentrations of TBT and total butyltins in transplanted mussels near the shipyard were in the range of 40-350 ng Sn/g and 74-530 ng Sn/g on a dry weight basis, respectively. Obviously, low TBT concentrations (6.0-53 ng Sn/gdw) were determined in mussels at four stations outside the shipyard. A negative gradient of TBT concentrations and TBT portion to total butyltin concentrations were found in both the surface water and transplanted mussels according to distance from the shipyard. In addition, TBT concentrations in surface water and transplanted mussels showed significant correlation (r(2) = 0.71; p < 0.001). These results indicate that the shipyard still releases fresh TBT into surrounding waters even after TBT regulation in Korea, and mussel transplantation is useful in evaluating TBT contamination in shipyard area.
将贻贝（Mytilus galloprovincialis）移植到一个大型造船厂周围的七个站点，为期126天，以评估三丁基锡（TBT）污染情况。尽管韩国已全面禁止在船舶上使用含TBT的涂料，但移植后的贻贝中仍发现有丁基锡化合物积累。在造船厂附近移植的贻贝中，TBT和总丁基锡的浓度以干重计分别在40 - 350 ng Sn/g和74 - 530 ng Sn/g范围内。显然，在造船厂外四个站点的贻贝中测定出低TBT浓度（6.0 - 53 ng Sn/gdw）。根据与造船厂的距离，在地表水和移植的贻贝中均发现TBT浓度以及TBT占总丁基锡浓度的比例呈负梯度。此外，地表水和移植贻贝中的TBT浓度呈现出显著相关性（r(2) = 0.71；p < 0.001）。这些结果表明，即使韩国对TBT进行了管控，该造船厂仍在向周围水域释放新的TBT，并且贻贝移植对于评估造船厂区域的TBT污染是有用的。
