中文摘要：

通过现场采样及室内分析对上海市主要饮用水源地黄浦江上游干流河段表层水体，表层沉积物及支流表层水体及其周边表层土壤中有机氯类内分泌干扰物的含量进行了检测。结果表明，黄浦江千流1到6号采样点，水体六六六含量在0．1～0．12μg·L^-1之间，滴滴涕含量在0．02～0．03μg·L^-1之间；表层沉积物中六六六含量在1．0～7．0μg·kg^-1之间，滴滴涕含量在3．0～32．0μg·kg^-1之间；支流7到15号采样点水体中只有HCH检出，含量范围为0．02～0．03μg·L^-1。支流周边土壤中DDT含量范同为2～8μg·kg^-1。根据表层水体和表层沉积物中的滴滴涕类内分泌干扰物的含量检测结果判断，4-6号采样点附近有新的DDTs污染物排人河道。根据实地考察推断，污染源可能为畜禽养殖场所排畜禽粪便。利用健康风险评价模型评价，目前黄浦江饮用水源地中HCH、DDT类污染物对人体健康的风险仍处较低水平。

英文摘要：

The upper stream of Huangpu River is the main surface drinking water sources of Shanghai. The concentrations of the HCHs and DDTs in the surface water and surface sediment collected from the upper stream of Huangpu River were determined. The results show that from the sampling point 1 to point 6, the concentrations of the HCHs in the surface water is from 0.1 μg·L^-1 to 0.12 μg·L^-1, the DDTs is from 0.02 μg·L^-1 to 0.03μg·L^-1; the concentrations of the HCHs in the surface sediment is 1.0～7.0 μg·kg^-1 and the DDTs is 3.0～32.0 μg·kg^-1. From the sampling point 7 to point 15, the concentrations of HCHs is 0.02～0.03 μg·L^-1 in the surface water of the mainly branches of the Huangpu River. The concentrations of DDTs is 2～8 μg· kg^-1 in the surface soil sampled from the side of the main branches of the Huangpu River, The concentrations of the DDTs indicate that there are new DDTs input in the area of sampling point 4 to point 6, imPlying that the new DDTs maybe come from the animal poultry manure which spill from the farms nearby. Based the model of water environmental health risk assessment, the risk of the HCHs, DDTs is low in the main drinking water sources of Shanghai.
