摘要
氟是人体必须的元素之一,人体氟的主要摄入来源是饮用水.永城矿区是饮用水型地氟病发病区.地下水中氟的含量与水温、pH值以及地下水的水化学成分有关.从定性和定量方面讨论了矿区地下水中氟从固相转入液相的过程,详细讨论了水温、pH值以及地下水的水化学成分对该过程的影响.
Fluorine is one of the essential elements to human health.Drinking water is the most important source of fluorine for human body.The fluorine content in groundwater in Yongcheng area is 1.0 to 2.73 mg/L,which is harmful to human health,for the fluorine content in drinking water is not allowed to be higher than 1.0 mg/L.In the studied area,the fluorine content is related to the pH value,the chemistry and temperature of water.In this paper,the authors qualitatively and quantitatively discuss the conversion of fluorine from fluorine bearing materials into groundwater,and analyze the influence of pH value,the chemistry and temperature of groundwater to the conversion.
