土壤重金属污染特点及治理策略分析

Characteristics and Management Strategies of Heavy Metal Pollution in Soil

目前,我国农田重金属污染呈现出由矿区向农区转移、由城郊向乡村延伸、由上游向下游转移的趋势,同时出现了重金属污染从水土链向食品链延伸的现象。这意味着农田重金属污染正由逐步积累阶段开始进入突发性、连锁性、区域性爆发的阶段,人们必须引起高度的重视。土壤重金属污染直接关系到农产品的质量安全以及人类和动物的健康,因此,必须采取措施防控和治理土壤重金属污染,提高耕地土壤质量,保障食品安全。简要阐述了土壤重金属污染的现状和特点,提出了土壤重金属污染的治理策略,以供参考。

At present, our country farmland heavy metal pollution showing by the mining to the agricultural areas transfer, from the city to the suburbs rural extension, from upstream to downstream transfer trend, pollution of heavy metal in soil chain to food chain extension phenomenon has appeared at the same time. This means that the heavy metal pollution in farmland is beginning to enter into the stage of sudden, chain and regional outbreaks, and people must pay high attention to the stage of heavy metal pollution in farmland. Heavy metal pollution in soil is directly related to the quality and safety of agricultural products and human and animal health. Therefore, measures must be taken to prevent and control soil heavy metal pollution, improve the quality of cultivated land, and ensure food safety. This paper briefly describes the status and characteristics of heavy metal pollution in soil, and puts forward the treatment strategy of heavy metal pollution in soil.
