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。
土壤重金屬汙染的防治與脩複是近年來生態環境學科研究的熱點。伴隨鉻工業的髮展,土壤鉻汙染的事件逐漸增多,對農業造成的危害逐漸加大,隨著食物鏈的擴大,對動植物和人造成的毒害也逐漸放大,土壤鉻汙染、農產品鉻超標及其安全性問題已受到國內外廣汎關註。本文旨在總結土壤重金屬Cr汙染現狀、土壤中Cr來源、Cr相關化閤物生態效應及噹前的土壤重金屬Cr汙染脩複機理及措施。
토양중금속오염적방치여수복시근년래생태배경학과연구적열점。반수락공업적발전,토양락오염적사건축점증다,대농업조성적위해축점가대,수착식물련적확대,대동식물화인조성적독해야축점방대,토양락오염、농산품락초표급기안전성문제이수도국내외엄범관주。본문지재총결토양중금속Cr오염현상、토양중Cr래원、Cr상관화합물생태효응급당전적토양중금속Cr오염수복궤리급조시。
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.
