植物对重金属污染土壤修复的研究进展

Research Progress on Remediation of Heavy Metal Contaminated Soil by Plants

重金属污染土壤是环境污染中备受关注的问题之一,威胁农业生产、食品安全,并可通过食物链富集到人体当中,给人类和环境造成严重危害。植物修复重金属污染土壤,具有无二次污染、美化环境等优点。该文阐述了重金属污染土壤的修复方法、修复重金属污染土壤植物的种类及修复机理、植物修复重金属污染土壤的强化措施,总结归纳了目前存在的问题,并对植物修复重金属污染土壤的研究进行了展望。

Heavy metal contaminated soil is one of the most concerned issues in environmental pollution. It threatens agricultural production, food safety, and can be enriched in the human body through the food chain, causing serious harm to humans and the environment. Phytoremediation of heavy metal contaminated soils has the advantages of no secondary pollution and beautification of the environment. This article expounds the remediation methods of heavy metal contaminated soil, the types and mechanisms of remediation of heavy metal contaminated soil plants, and strengthening measures for phytoremediation of heavy metal contaminated soil, summarizes the existing problems,and prospects for phytoremediation of heavy metal contaminated soil.
