Residue levels of organochlorine pesticides (OCPs) in multiple compartments (water, soil and sediment) along the Jinjiang River mainstream to Quanzhou Bay were monitored to elucidate sources and fate. The concentrations of OCPs in surface soil of the watershed of the Jinjiang River (2.44 ± 1.97 ng/g for hexachlorocyclohexanes (HCHs) and 11.4 ± 8.46 ng/g for dichlorodiphenyltrichloroethanes (DDTs)) and the Quanzhou Bay (1.81 ± 2.15 ng/g for HCHs and 9.72 ± 14.66 ng/g for DDTs) were comparable. The concentrations of HCHs and DDTs in dissolved phase were 55-94% for the total HCHs and ten to sixteen percent for the total DDTs in the Jinjiang River. High correlations of OCPs between suspended particulate matter (SPM) and sediment (p<0.01) were found in this study, which demonstrated that OCPs absorbed onto SPM was the major source in the sediment of Quanzhou Bay. The use of lindane was the major source of HCHs in the study region. Dicofol pollution was found in water of the Jinjiang River and sediment of Quanzhou Bay. Based on the sediment quality guidelines, DDTs pose more ecotoxicological risk in environment of the Jinjiang River and Quanzhou Bay.
对晋江干流至泉州湾多个环境介质（水、土壤和沉积物）中的有机氯农药（OCPs）残留水平进行了监测，以阐明其来源和归宿。晋江流域表层土壤中 OCPs 的浓度（HCHs 为 2.44±1.97ng/g，DDTs 为 11.4±8.46ng/g）和泉州湾（HCHs 为 1.81±2.15ng/g，DDTs 为 9.72±14.66ng/g）的浓度相当。在晋江，HCHs 和 DDTs 在溶解相中分别占总 HCHs 的 55-94%和总 DDTs 的 10-16%。本研究发现，悬浮颗粒物（SPM）和沉积物中 OCPs 之间存在高度相关性（p<0.01），这表明吸附在 SPM 上的 OCPs 是泉州湾沉积物的主要来源。林丹的使用是研究区域 HCHs 的主要来源。在晋江河水和泉州湾沉积物中发现了三氯杀螨醇污染。根据沉积物质量基准，DDTs 在晋江河和泉州湾的环境中构成更大的生态毒理学风险。
