摘要
地下水中汞元素的形成， 主要是含汞矿物岩土溶解作用的结果， 但其含量一般很低。汞与人体关系密切， 结肠癌、肺癌死亡率与土壤中汞含量呈正相关， 胃癌死亡率则与汞元素含量呈负相关。地下水汞元素含量小于１μｇ／Ｌ 时， 不会对人体健康产生危害。
The lixiviation of mercury-contained, although low, mineral rock-soli contributes to the form of mercury in the underground water. soil contributes to the form of mercury in the underground water.Mecury has close relation with human body. Colon Cancer and lung Cancer have positive correlation with mercury contained in the soil while stomach cancer has negative correlation with it.When the volume of mercury is lower than l μg/L, it does no damage to human healty.
