摘　　要：通过分析研究吉林省中部农业土壤中DDT的含量和组成,探讨了该区土壤中DDT的残留特征及其可能的生态风险。研究结果表明,吉林省中部农业土壤中普遍残留DDT,质量分数为0.384-54.159μg/kg,残留水平较低,土壤DDT同系物中以p,p＇-DDT和p,p-＇DDE为主。DDT的组成表明,土壤中DDT主要是过去输入环境的DDT及其降解产物,但近期仍有少量的DDT输入。生态风险评估则显示该区土壤中的DDT具有一定的生态风险,应予以重视。The residual characteristics and ecologic risk of dichloro-diphenyl-trichloroethane（DDT） in agricultural soil were discussed on the base of study on the content and composition in the middle Jilin Province.The results showed that DDT was detected commonly in the agricultural soil with the lower level ranging from 0.384 μg/kg to 54.159 μg/kg and p,p＇-DDT and p,p＇-DDE were the major isomers.The composition of DDT indicates that the residues include the DDT used before forbiddance and their degrading products as well as a small amount of DDT used recently.There was some ecological risk of DDT in this area which should be paid attention to.
