Abstract:
Objective To understand the relationship between the fluoride contents and the total hardness, pH value, the depth of well in the endemic fluorosis areas of Hejian city. Methods 40 villages in 2 towns of Hejian city were selected randomly and the well water samples in these villages were collected and determined. Results The contents of fluoride in the well water were higher than the limit(1 mg/L) in Sanitary Standard for Drinking Water Quality (China, 2001), ranged 1.2~4.4 mg/L, with a mean of 2.80 mg/L. The fluoride contents increased as the total hardness decreased (r=-0.615, P
