土壤中有机污染物的植物修复研究进展

PHYTOREMEDIATION OF ORGANIC POLLUTANTS IN SOILS

植物修复是土壤有机污染物修复的有效途径之一,主要包括植物吸收、根际土壤酶促进降解和微生物对其的一系列降解。本文简述了植物修复的含义,系统综述了植物修复有机污染物的机理,并阐述了利用植物对农药、氯代化合物、多环芳烃和其它有机污染物进行修复的研究成果与应用,展望了今后进一步研究的重点。

Phytoremediation is an effective method to remediate soil contaminated with organic pollutants in soil, mainly through plant absorption, rhizospheric-enzyme-stimulated degradation and microbial degradation. This paper discussed in brief the notion of phytoremediation, reviewed mechanisms of the phytoremediation, and findings in the research on using plants to remediate soil contaminated with pesticides, organochlorine compound, polycyclic aromatic hydrocarbons and others organic pollutants and their application, and looked into future of the study for focal points.
