本文评价了中国东南部莆田地区兴化湾及其邻近流域有机氯农药的污染现状和分布。分别从两个流域和兴化湾采集了25个表层土壤样品和2个沉积物岩样。结果表明，木兰河流域(MRW)、丘陵河流域(QRW)、内湾柱样(IBC)和开湾柱样(OBC)的有机氯农药含量分别为4.96~38.20 ng/g、4.62~22.80 ng/g、1.84~80.46 ng/g和1.87~23.43 ng/g。有机氯农药的平均浓度顺序为：IBC>MRW>QRW；>OBC。近一段时期有机氯农药浓度较高，可能表明仍有一定数量的有机氯农药输入到该地区。
This study evaluated the contamination status and distribution of organochlorine pesticides (OCPs) between Xinghua Bay and adjacent watersheds in Putian region, southeast China. Twenty-five surface soil samples and two sediment cores were collected from two watersheds and the Xinghua Bay, respectively. Results showed that the concentrations of OCPs in samples of the Mulan River Watershed (MRW), the Qiulu River Watershed (QRW), the inner bay core (IBC) and the open bay core (OBC) were in the range of 4.96–38.20 ng/g, 4.62–22.80 ng/g, 1.84–80.46 ng/g and 1.87–23.43 ng/g, respectively. The mean concentration of OCPs was in an order: IBC > MRW > QRW > OBC. The higher concentration of OCPs in recent periods may suggest that a certain amount of OCPs were still input to this area.
