摘要：

Concentrations of organotin compounds in sediments from four sites in the Gota alv estuary, SW Sweden, range from 17 to 366 ng/g dw for tributyltin (TBT) and from 1.5 to 71 ng/g dw for triphenyltin (TPT), similar to results from other harbours and marinas and from an earlier study in the Goteborg Harbour, which is located in the estuary. Also dibutyltin, monobutyltin, diphenyltin and monophenyltin, the degradation products of TBT and TPT, were found. TBT concentrations are the highest in the inner harbour and in the upper sediment layer of ca. 10 cm, indicating the risk for mobilisation of TBT bound in surface sediments in the frequently disturbed harbour environment.
