土壤典型持久性有机污染物界面行为及调控技术研究进展

Advances in Interfacial Behavior and Regulation Technology of Typical Persistent Organic Pollutants in Soil

土壤是持久性有机污染物(POPs)重要的源和汇,由于POPs具有的"三致"性,其造成的土壤污染已演变为全球性的主要环境问题之一.POPs进入土壤后的界面行为直接决定其生物降解程度,因此关于POPs在土壤中界面行为的研究,对于保护土壤生态系统具有重要意义.本文总结了不同种类典型POPs的具体界面行为,阐述了土壤复合污染及其界面行为,并对土壤POPs调控技术,特别是新兴化学—微生物联合土壤修复技术研究进展进行了讨论.指出POPs特别是新型POPs在土壤中的界面行为、调控技术及其应用研究,POPs—重金属复合污染情况下重金属对POPs界面行为的影响,研发基于生物有效性的高效土壤POPs污染生物修复技术等是未来的重点研究方向.

Soil is the important source and sink of persistent organic pollutants(POPs).Because of its severe toxicities,the soil pollution which was caused by POPs has evolved into one of the major global environmental issues.The interfacial behavior of POPs after entering the soil directly determine its degree of biodegradation.Therefore,the studies of the interfacial behavior of POPs in soil have great significance for protecting the soil ecosystem.This paper summarizes the specific interfacia behavior of different types of POPs,elaborates the soil composite pollution and its interfacial behavior,and discusses the research progresses of soil POPs regulation technology,especially the emerging chemical-microbial combined soil remediation technology.It points out the interfacial behavior of POPs,especially for emerging POPs in the soil,the regulation technology and its application,the impact of heavy metals on the interfacial behavior of POPs in the case of POPs-heavy metal composite pollution,and the development of bioavailability-based high-efficiency soil POPs pollution bioremediation technologies will be the future research directions.
