摘要	In order to study the contamination of organotins in the tributary of Three Gorges Reservoir Area, surface water samples, collected from the backwater zone of the Daning River and the Xiaojiang River in May 2013, were extracted by solid phase micro-extraction (SPME) and determined by using gas chromatograph (GC) with mass spectrum (MS) to analyze the organotins, such as butyltins and phenyltins. The results show that tributyltin (TBT), triphenyltin (TPhT), together with all their degradation byproducts, were found in surface water. Monophenyltin (MPhT) was the dominant phenyltins in both the Daning River and the Xiaojiang River. However, as for butyltins, monobutyltin (MBT) dominated in the Daning River while MBT and dibutyltin (DBT) were prevailing in the Xiaojiang River. Except for the monitoring station of Dachang, there is no recent input of TBT and TPhT in the Daning River and the Xiaojiang River, indicating that natural degradation of TBT and TPhT occurred intensively in surface water. ©, 2015, Science Press.
