%X 19 kinds of organochlorine pesticides(OCPs)in surface sediments of Chongqing karst areas were analyzed by GC-ECD.The total concentration range of OCPs was 4.73~286.03 ng/g,the concentration range of DDTs was 0.35~181.78 ng/g and the concentration range of HCHs was nd~23.53 ng/g.Compared with other rivers,the organchlorine pesticides in sediments of Chongqing typical karst areas is in the high level.DDE/DDD demonstrates DDT degraded in the aerobic environment except Jiangjiarongdong.(DDD+DDE)/DDTs shows no n...
