s在土壤中的残留现状及植物修复研究进展

is one kind of Persistent organic pollutants. Although the most countries have forbidden using DDT, it still has a great quantity to leave in soils. At present, phytoremedia- tion is an effective method to remedy DDTs- contaminated soils. This paper discussed in brief DDTs residual in soils from home and abroad, reviewed in detail the phytoremediation of DDTs- contaminated soils from absorption and metabolism, root-exudates-stimulated degradation and rhizospheric microbial degradation. At the same time, according to the research achievements of utilizing plants to remedy DDTs-contaminated soils, this paper looked in the fields that needed to study further in the future.
