浅表环境中氟离子富集规律的轮次分析

Times of Rotation Study of Fluorine Enrich Patterns in Superficial Environment

浅表环境中的氟含量与人类关系非常密切,地氟病的产生和流行与此无法分开.论文以河南省周口地区为例运用轮次分析方法对浅表环境中的氟离子富集规律进行探讨,得出以下主要结论:(1)包气带中水分的垂直交替运动比较强烈,含氟组分和其他常量组分在垂直交替过程中参与了淋溶、吸附解吸、络合解离、离子交换等一系列的物理化学过程,实现了氟和可溶盐在包气带中的迁移富集;(2)浅表环境中土壤是地下水氟化学场的调节器,在一定条件下不仅可吸附氟又可将吸附氟释放到地下水中,完成一个水土间的循环过程.

Superficial environment, fluorine content is close with people and can＇t divided of producing and popular about Endemic Fluorosis. The paper studies fluorine enrich patterns in Superficial environment of u- sing Times of rotation in case Zhoukou region, and has conclusions： （1） In vadose zone, water is more strong on vertical changing, and it participates in physical and chemical process of eluviating,adsorbing,dis- sociating and exchanging. It has finished moving and enriching of the fluorine and soluble salt; （ 2） In Su- perficial environment, soil is a conditioner of groundwater fluoride chemistry. Not only it adsorbs fluorine, but also releases fluorine into groundwater on the condition, and forms a complete circle between biology ~people} and water of content fluorine.
