摘要
测定了不同典型农业生产功能区土壤中有机氯农药（OCPs）残留,六六六（HCHs）、滴滴涕（DDTs）各同分异构体均有不同程度检出。结果表明,DDTs含量占有机氯农药含量的56%-95%,是污染的主要贡献污染物。HCHs中γ-HCH占45%-79%,DDTs中DDE〉0%。其畜禽养殖基地和污水灌溉区污染指数（DDTs）分别为1.6（重污染）和0.6（中污染）,其余均小于0.5（轻污染）。
Resudues of OCPs were detected in soils of different typical agro-yielding areas.All structures of HCHs and DDTs were detected in differ degree in soils.Proportion of DDTs is 56%-95% in OCPs,and is the main contribution of OCPs pollutions.Proportion of γ-HCH is 45%-79% in HCHs,the proportion of DDE in DDTs is above 40%.The indexes are p_（（domestic animals breed areas,DDTs））=1.6（severe pollution）,p_（（areas sewaged,DDTs））=1.6（middling pollution）,other indexes are all less 0.5（light pollution）.
