土壤重金属Cr污染及其治理研究进展

Research Progress of Heavy Metal Cr Pollution at Soil and Its Treatment

土壤重金属污染的防治与修复是近年来生态环境学科研究的热点。伴随铬工业的发展,土壤铬污染的事件逐渐增多,对农业造成的危害逐渐加大,随着食物链的扩大,对动植物和人造成的毒害也逐渐放大,土壤铬污染、农产品铬超标及其安全性问题已受到国内外广泛关注。本文旨在总结土壤重金属Cr污染现状、土壤中Cr来源、Cr相关化合物生态效应及当前的土壤重金属Cr污染修复机理及措施。

Prevention and repairment of soil heavy metal Cr pollution is hot spot of ecological science research.With the developing of Cr industry,the soil Cr pollution accident increasing gradually,the harm to agriculture increasing gradually;with the enlarge of food chain,the poison to animals,plants and human also amplifiering,the soil Cr pollution,chromium over standard of agricultural products and its securty problem are attention widely.The aim of paper is summarying the present situation of soil heavy Cr pulltion,the Cr sourse in soil,ecological effect of Cr relative compounds,repair mechanism and measures of soil Cr pollution at present.
