陇东地区饮用水中氟含量和分布研究
Study on Concentration and Distribution of Fluoride in Drinking Water in the Longdong District
摘要
Abstract
With northern of Longdong District which situated in the central of Loess Plateau,Gansu Province as study object,fluoride concentration in drinking water was determined by using the SPADNS colorimetric method and the distribution law was discussed. Drinking water was classified into three types corresponding to the water from boreholes,shallow wells,and water cellars (water cellar was used to collect rain water) respectively. There were 127 water samples. The results showed that the concentrations of fluoride in the boreholes were varied from 1.01 to 3.95 mg/ L, ranging from 1.07 to 4.60 mg/L for the shallow wells, as well as from 0.09 to 1.24 mg/L for water cellars. From the analysis, it was found that the concentrations of fluoride in ground water from either boreholes or shallow wells were above the maximum allowable concentration for fluoride in drinking water of 1.0 mg/L in China,while for the samples from water cellars it was almost lower than the maximum allowable concentration with 78 out of 80. According to the distribution of fluoride, it was obvious that fluoride level in drinking water has integrated strongly to geological form and environmental factors,and their distribution display the similar regularity:their concentration decrease from northern to southern.关键词
