Therefore, the exploration of the distribution of high groundwater fluoride and the influencing factors is of great practical significance for regional development of groundwater resources and drinking water safety (Li et al., 2019). Fluoride in natural water bodies is mainly derived from geological ...
Fluoride is widely found in nature.Fluoride content in natural water is generally 0.3 to 0.5 mg / L.Groundwater flowing through the fluorite layer can sometimes be as high as 2-5 mg / L.China's groundwater distribution of a wide range of areas, due to long-term consumption of high flu...
