摘要
Cd在土壤中有稳定、积累和不易消除的特点 ,且可通过食物链富集使人体产生慢性中毒。我国农村镉污染尤其严重。植物修复技术是优秀的土壤镉污染治理技术 ,近两年来成为研究热点。本文阐述了土壤镉污染植物修复技术的机理、具体做法和技术进展。
Cadmium in the soil is stable,accumulative,and hard to be removed.Through food chain,it may do harm to people by resulting in chronic diseases.In our vast countryside,the soil pollution by cadmium is serious.Recently,plants remediation has been a focus of attention because it is an excellent technology in the field of harness of soil polluted by cadmium.Its principles,concrete practices,and development have been expounded in the article.
