Thereby based on theanalysis of different conservation characteristics of fluorine in local groundwater,through the analysis of human body with the representative complex state offluorine in food chain , the conclusion that in the groundwater fluorine in statesof complexing ion and organic has negative effects on human bodies has been basicallymade, which provides clues for further researches on the mechanism of endemicfluorosis.
