摘要
农田土壤的重金属污染,直接影响农作物的产量和品质,从而威胁人类健康,因此已成为人们十分关注的热点环境问题。有机物料在农村地区价廉易得,对大面积重金属污染农田的修复具有较好的应用前景。对有机物料修复重金属污染农田土壤的机理、影响因素以及提高有机物料修复效果的措施进行了综述,为提高农产品的安全性和农业废弃物的有效利用等提供参考。
Soil heavy metal contamination is an important environmental issue due to its influences on yield and quality of crops and thus threatening human health.Organic materials have been considered to be the potential prospect in treating heavy metal contaminated soil because of its effectiveness,easily availability and low price.This paper introduces the mechanisms of organic materials in the contaminated soils remediation,the influencing factors and some measurements.
