多环芳烃污染生物修复研究进展

摘要

多环芳烃（polycyclic aromatic hydrocarbon，PAHs）是一类对环境有严重危害的持久性有机污染物。具有高生物富集性、致癌性、致毒性和难降解性，修复治理 PAHs 污染环境备受国内外政府及学者的关注。目前主要采用物理、化学以及生物方法对多环芳烃污染的土壤和水体进行修复。其中生物修复是一种高效、经济和生态可承受的环保技术，具有成本低、无二次污染等优点。本文从植物修复、微生物修复以及植物-微生物联合修复方面，阐述了国内外生物修复 PAHs 污染的最新研究进展。指出了生物修复 PAHs 污染环境需要进一步解决的问题，并对未来发展趋势进行了展望。%Polycyclic aromatic hydrocarbons(PAHs)is a kind of persistent organic pollutants(pops)having serious harm to the environment,and high bio-accumulation,carcinogenicity,toxicity,and difficult to degrade,redemption and control PAHs pollution onto the environment had paid many close attentions by government and scholars both at home and abroad. At present the redemption and the control of the PAHs pollution on soil and waters mainly using chemical,and biological methods. Among them bio-redemption is a kind of high efficient,economic,and ecologically sustainable environmental technology,it has the advantages of low cost,non secondary pollution etc. The authors elaborated the latest advances in bio-redemption of PAHs pollution both at home and abroad from the aspects of phyto-redemption,microbial redemption,as well as plant-microbe joint redemption. And pointed out that bio-redemption of PAHs pollution of environment need further efforts to solve the problems,and prospected the developing trend in the future.
