摘要
随着工农业发展,土壤中镉污染程度日趋严重。镉通过在作物体内富集而进入食物链,对人畜健康构成巨大威胁。文中概述了土壤中镉污染来源、赋存状态及其生物有效性、对人体及生物健康危害等的研究情况,分析了土壤镉污染生物修复的研究动态,并提出了今后的研究方向。
cadmium contaminated soil have seriously threatened human and animals' health due to its bioaeeumulation in the food ehain along with the development of industry and agrieulture. Current status of eadmium eontaminated soil and its source,modes of occurrence of cadmium and its bioavailability in soil,harm of cadmium on biological and human health, and the remediation methods of cadmium contaminated soil are reviewed in this paper. Furthermore, some suggestions for future researches in this field is prospected.
