摘要:本文选用 GC/ECD 分析北京市官厅水库水体中 27 种有机氯农药(OCPs)残留情况,
并探讨该区水体 OCPs 残留特征及其可能的健康风险。研究结果表明,27 种 OCPs 均有不同
程度的检出,含量较高的组分为阿特拉津,总有机氯农药含量为 ~。研究
区 OCPs 的来源解析表明,官厅水库水体中没有新的 HCHs 及 DDTs 的输入;历史数据对比
发现水体阿特拉津残留浓度呈现逐年下降趋势。利用健康风险评价模型对土壤中 HCHs、
DDTs 和阿特拉津所致健康风险的评价结果表明,目前研究区水体中 OCPs 类污染物对人体
健康的风险处于较低水平。

Abstract: The residual characteristics of anochlorine pesticides (OCPs) and health risk of
dichlorodiphenyltrichloroethanes (DDTs), hexachlorocyolohexanes (HCHs) and atrazine in
Beijing Guanting reservoir was studied in this paper. Pesticides were analyzed by GC/ECD. The
result showed that 27 OCPs were detected in the water samples. Furthermore, atrazine had higher
concentrations. The concentrations of ∑OCPs ranged from to ng/L. The source of
OCPs was researched and the result indicated that there are no new inputs of DDTs and HCHs.
Moreover, the residues of atraz
