| Spatial Distribution Characteristics and Origin of Fluorine in Groundwater of Huaibei City, Anhui Province |
| On the basis of hydrogeological survey and sample analysis, fluorine in the groundwater was taken as the study object in Huaibei City, Anhui Province. Analyses of 338 groundwater samples show that the overall spatial distribution of fluorine decreases from north to south. The mean of the fluorine values in the north is higher than 2.0 mg/L. The standard-surpassing rate of fluorine content of the groundwater is 35.5%, much higher than that of the whole Huaihe River Basin whose standard-surpassing rate is 20.14%. The standard-surpassing rate of shallow groundwater (≤ 50m) fluorine content is 40.45%, which is higher than that of the deep groundwater (> 50m) whose standard-surpassing rate is 16.9%. Excessive fluorine in groundwater is related to geological background, human activities and environmental conditions. |
