摘要 耕层土壤受重金属污染,既危害农业生产,又对人体健康产生不良影响,在城市人口稠密,工业发展迅速的地区尤其严重。本文以珠江三角洲平原区为例,论述了耕层土壤受重金属污染对农业生产,对环境及人体产生潜在的危害,分析了土壤重金属含量和分布规律以及污染状况,最后提出了对受重金属污染的土壤的防治措施。 The content, distribution and contaminated condition of heavy metals Cd, Pb, Hg in the soil at Zhujiang delta was studied in this paper. 'Three waste'is so much in this populous and developed area, that brings along a series of seri-ous environmental problems. The heavy metals Cd, Pb, Hg contaminated soil is the one of these, which damage the agriculture, make the farm products less and poor in quality. These heavy melals participate in the cycle of the farm ecdogical system, when they enter to the food chain, the har-mful effect also take place to people's health.Therefore, It is necessary to control the 'three waste', to drain them under strict criteria, then the heavy metal elements may be prevented to enter the soil.
