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 4.96-38.20ng/g, 4.62-22.80ng/g, 1.84-80.46ng/g and 1.87-23.43ng/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.
本研究评估了中国东南部莆田地区兴化湾及其相邻流域有机氯农药 (OCPs) 的污染状况和分布。分别从两个流域和兴化湾采集了 25 个表层土壤样品和 2 个沉积物岩芯。结果表明，木兰溪流域 (MRW)、秋芦溪流域 (QRW)、内湾岩芯 (IBC) 和外湾岩芯 (OBC) 样品中 OCPs 的浓度范围分别为 4.96-38.20ng/g、4.62-22.80ng/g、1.84-80.46ng/g 和 1.87-23.43ng/g。OCPs 的平均浓度顺序为：IBC>MRW>QRW>OBC。近期 OCPs 浓度较高，表明该地区仍有一定数量的 OCPs 输入。
