Study Of Endemic Fluorosis Regulation In Jilin Fluorosis Region Using Hydro-geochemistry Combination Different Model

Fluorine is the important element for human health, human can absorb fluorinefrom environment through all kinds of methods just like fooding and drinking,andthe content and the chemical form can play an importmant role in the fluorinecontent in human bodys and effect on the human health.The increasing anddesending of the fluorine content in body can effect on the human health. Accordingto the Standards for Drinking Water Quality,when the fluorine concentration ingroundwater is lower than1mg/L,the groundwater is look at the high fluorinewater.Human drinking the high fluorine content water frequently can causefluorosis.The content of fluorine in groundwater is relationship with the rate offluorosis,high content fluorine can cause high rate of fluorosis normally, but not allof the content flurine in groundwater in serious fluorosis areas is higher than lightfluorosis areas.This pHenomenon has a relationship with the hydrogeololgycondition and the hydro-geochemistry of groundwater.The rate of fluorinesupplying,draining and concentrating is different in all kinds of groundwaterhydrogeololgy condition,and different fluorine chemical forms can effect on theabsorbability in body.This article builds on a Hydro-Geochemistry CombinationDifferent Model to calculate the relationship between the fluorine and the otherelements in groundwater through investigating the pHysical geograpHycircumstances and the hydrogeololgy conditions in the west of Jilin Province andcontrasting the rate of fluorosis, then explores the regular conclusion.⑴The whole fluorine content is not accord to the rate of fluorosis actually.Normally, we consisder that the high fluorine content can cause the high rate offluorosis, but from the investigating result,some lower fluorine content area canappear serious flourosis area,and the higher fluorine content area is the light flourosisarea.We can not consider that the whole fluorine content has only relationship withthe fluorosis rate.⑵The fluorine content can be absorbed by body has direct relationship with the fluorosis rate.The fluoride has lots of chemical form in groundwater, and free state fluorinecan be absorbed easily, combined-state fluorine can be absorbeddifficultly.According to the investigation, the fluorosis rate in the west of jilinprovince area exist the appearance between the fluoride in groundwater. The fluorinecan be existed in what form is related to the groundwater dynamics condition and thehydro-geochemistry.⑶The fluorosis rate has relationship with the cycling rate of groundwater.From the investigation result of the fluorosis and hydrogeololgy conditions inthe west of Jilin Province,we can know that the high speed cycling groundwater areacan easily form light fluorosis regions and the low speed cycling groundwater areacan form middle or serious fluorosis regions normally.⑷When we study the relationship between fluoride and fluorosis,we mustconsider the other elemens and the chemical form in addition to the fluorine,and dowhole assessment to the relationship between the fluorine and the other element indifferent hydro-geochemistry conditions.
