环境污染日益严重的今天,由于重金属对人体的独特的危害性,重金属污染引起了全社会的广泛关注.面对重金属污染事件的高发态势,对环境中重金属污染源的分析研究越来越多.重金属具有显著的生物毒性,在环境中不会降解、消失,且能蓄积在生物体内,通过食物链对人体健康造成危害.本文全面分析了环境中重金属污染的几种主要来源途径,如大气中重金属沉降,农用物资如农药、化肥、塑料薄膜的不合理使用,污水灌溉,含重金属的矿业、工业废弃物的堆积,金属矿山酸性废水污染等.与此同时,针对这些污染源,本文综合论述了重金属污染的修复对策,如工程治理方法、化学治理方法、生物修复对策、农业治理措施以及一些新技术等,针对不同的污染源,采用不同的修复对策,以达到控制或缓解重金属污染的目的.

In today's world where environmental pollution has been increasingly serious, heavy metal pollution has drawn attention of the whole society, given its distinctive harm to human body. In light of increasing number of polluting incidents triggered by heavy metal, there have been more and more research focusing on polluting sources of heavy metal. Heavy metal's apparent biological toxicity can't be degraded or disappear; rather, it can stay inside organism's body and do much harm to human body through food chain. The article analyzes some of the main sources of heavy metal pollution, such as heavy metal sedimentation, irrational use of agricultural material like pesticide, fertilizer, plastic film, irrigation by waste water, accumulation of waste heavy metal from mineral or industrial source, and acid waste water from metal mines. Meanwhile, targeting these polluting sources, this article also introduces some of counting measures to heavy metal pollution, such as engineering, chemical, biological, agricultural treatment and some latest technology. Different measures should be applied to different polluting sources in order to control or reduce metal pollution.
