宜宾市城郊各典型地土壤中重金属污染调查

Investigation on Heavy Metal Pollution in Typical Soil in Yibin Suburb

土壤污染,尤其是重金属污染近年来比较突出,土壤的重金属污染不但会对农作物产生一定的危害,而且也会间接地危害到人类[1]。同时,由于农业环境中的重金属污染尤其是土壤重金属污染不易发现,具有隐蔽性和潜伏性,不易降解,具有不可逆性和长期性,造成的后果尤其严重。因此,加强对菜地土壤重金属污染的调查和研究是当前进行农业生态环境保护的重要方向。

Soil pollution, especially the pollution of heavy metals, has become more prominent in recent years. The pollution of heavy metals in soil will not only cause certain harm to crops growing on the soil, but also indirectly harm human beings [1]. At the same time,the heavy metal pollution in the agricultural environment, especially in the soil, is diffi cult to fi nd, hidden and latent, diffi cult to degrade,irreversible and long-term, and the consequences are particularly serious. Therefore, strengthening the investigation and research of heavy metal pollution in vegetable soil is an important direction of agricultural ecological environment protection.
