Abstract: representative soil samples were collected from the middle and northern parts of Anhui Province. The results of the soil sample test show that the contents of soluble fluorine in soils ranged from 0.38 mg/kg to 12.69 mg/kg, averaging 2.38 mg/kg. The soluble fluorine content in soil is higher in the south than in the north of the region. The test results show the following order of soil types as regard to the soluble fluorine contents from high to low: Shajiang dark soil, Yellow brown earth and Purple soil, Paddy soil, Limy soil. The test results also show the following order of soil parent materials as regard to the soluble fluorine contents from high to low: loess like sediment, Huanghe River alluvial deposit, Purple rock, Xiashu loess, Limestone, weathered acidic rock, river alluvial deposit. The contents of soluble fluorine in soil was found to be positively correlated with the pH values of the soils.
