被农药污染的土壤植物修复研究进展

随着农药施用量的增加,农药污染土壤给生态环境造成了极大的危害,并引起了人们的普遍关注。传统的修复方法因其价格昂贵不能普遍采用,植物修复是近年来兴起的一种利用植物积累、吸收、降解等去除土壤、水、和沉积物中污染物的新方法。综述了农药污染土壤的植物修复国内外研究进展,讨论了植物吸收、植物提取、植物稳定、植物挥发、根际降解以及根际区酶的作用,同是指出了植物修复存在的不足。植物修复技术以其独特的优点必将成为污染环境修复研究热点之一。

Research Progress of Pesticide Contaminated Soils

With the increment of the pesticide, pesticide contaminated soils is a very important problem, has been attracting considerable public attention over the last decades. Traditional methods were not adopted for its enormous costs. Phytoremediation ia an emerging new technology that use plant to degrade, assimilate, or detoxify in soils, water, and sediments. The research progress of pesticide contaminated soils is summarized, Phytoaccumulation, phytoextraction, phytostabilization, phytotransformation, phytovolatilization, rhizodegradation and the role of enzymes are discussed, point out the constraints at the same time. At last, phytoremediation is pointed out for its special advantages, and looked into future of the study for focal points.
