【摘要】 土壤重金属污染的危害范围广泛,使用传统的物理和化学修复方法成本高,对环境扰动大,而利用植物修复的效果较为明显,易于操作。本文论述了土壤重金属污染的单一植物、植物与微生物联合、植物与化学方法相结合的修复方法,着重介绍了重金属超富集植物的研究和植物体内螯合肽(PCs)的合成。生物螯合剂的应用及土壤重金属污染的动物、植物和微生物的联合修复将是未来研究的热点。更多还原

【Abstract】 The contamination harm by soil heavy metals is extensive. The cost of traditional physical and chemical remediation methods is expensive. Moreover, the disturbance of traditional methods on environment is severe. It has been proven that phytoremediation is more effective than other methods and easily operated. This paper discussed the phytoremediation technique of single plants, combination of plants and microbes, as well as combination of plants and chemical treatment, and emphatically introduced the research of hyperaccumulation plant and the synthesis of phytochelatin (PCs). It is forecasted that future disquisitive emphases are the application of biochelator along with combination remediation of animals, plants and microbes.更多还原
