试述土壤污染对人类健康的侵害

Discusses the Soil Pollution Infringement in Human Health

农业生产中的污水灌溉、农药、化肥的使用、固体废弃物的堆弃及汽车尾气等等都对土壤造成了污染。土壤的污染具有隐蔽性、累积性、长期性和难治理性。土壤环境一旦遭受污染,将是人类的灾难。土壤污染带来的生物性传染病、重金属污染、残留农药污染等将对人体健康造成严重侵害,从源头控制污染势在必行。

In agricultural production, sewage irrigation, the use of pesticide and fertilizer, the discard of solid waste and the car exhaust, all these cause the soil pollution. The soil pollution has many characteristics, such as imperceptibility, cumulative- ness, the protracted nature and difficult to control. Once the soil environment has been polluted, it will be the disaster of human. The soil pollution brings many problems, for example, biological infectious disease, the pollution of heavy metal, the pollution of residual pesticides. It will badly infringe the human health. Accordingly, the control of the pollutant source is imperative.
