[Environmental and geochemical behaviors of fluorine and its impacts on ecological environment].

In past decades, fluorine exposure of plants and human caused by regional geochemical anomalies of fluorine or environmental pollution has received widespread concerns. Many in-depth researches have been conducted on the geochemical behavior of fluorine in different environmental media, but with disputes and uncertainties. We reviewed the research advances on geochemical behaviors of fluorine in the atmosphere, water and soil, including source, quantity, existence form, migration, transformation, and controlling factors. The observation of correlation between geochemical behaviors of fluorine and plant and human fluoride exposure was also reviewed. Moreover, we proposed that the future research on environmental geochemical behaviors of fluorine should give priority to particular directions.
