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>40%.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).
測定瞭不同典型農業生產功能區土壤中有機氯農藥(OCPS)殘留,六六六(HCHs)、滴滴涕(DDTs)各同分異構體均有不同程度檢齣.結果錶明,DDTs含量佔有機氯農藥含量的56%～95%,是汙染的主要貢獻汙染物.HCHs中γ-HCH佔45%～79%,DDTs中DDE>40%.其畜禽養殖基地和汙水灌溉區汙染指數(DDTs)分彆為1.6(重汙染)和0.6(中汙染),其餘均小于0.5(輕汙染).

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_((domesticanimals breed aress,DDTs))=1.6 (severe pollution), P_((areas sewaged,DDTs)) = 1.6(middling pollution) ,other indexes are all less 0.5(light pollution).
