摘要
新污染物在土壤中具有生物毒性、环境持久性和生物积累性等特征,广泛存在于我国污染场地中.对污染场地土壤中新污染物的研究现状、迁移转化机制和修复进程方面的研究进行综述,对典型新污染物在土壤中的来源和生物毒性进行详细讨论,并展望我国污染场地新污染物修复的未来,以期对今后新污染物检测—代谢途径—土壤修复技术全链条深入研究、新污染物治理的理论依据和实际应用的发展提供参考.
Abstract
Emerging contaminants(ECs)are biotoxic,environmentally persistent,and bio-accumulative in soil,and are widely present in contaminated sites in China.This paper reviews the current research status,migration and transformation mechanisms,and remediation processes of new contaminants in contaminated site soils,discusses in detail the sources and biotoxicity of typical new contaminants in soils,and looks into the future of new contaminant remediation at contaminated sites in China.It is expected to provide a reference for future in-depth research on the whole chain of new pollutant detection-metabolism pathway-soil remediation technology,and the theoretical basis of new pollutant treatment,and to promote the development of the related practical application.
