土壤中滴滴涕的来源·风险与修复

Source,Risks and Remediation of DDT in Soil

DDT禁用几十年后,土壤中DDT的历史残留依然存在,同时新兴污染源使土壤中DDT污染状况有所改变。有关DDT的毒理学、健康风险评估研究也有了新的进展。综述了近年土壤中DDT的来源、毒性及健康风险最新研究成果,在此基础上介绍了较成熟的被DDT污染土壤的修复技术,为土壤中DDT的管控工作提供技术支持。

Decades after DDT was banned,the historical residues of DDT in the soil still exist,while emerging sources of pollution have changed the status of DDT pollution in the soil.Progress has been made in toxicology and health risk assessment of DDT recently.In this paper,source,toxicity and health risk of DDT in soil in the past few years have been reviewed.Moreover,practical remediation technologies of DDT contaminated soil were proposed to provide technical support for the management and control of DDT in soil.
