follow site Nuclear reaction based Proton Induced Gamma Emission (PIGE) analytical method was employed for the quantitative measurement of fluorine in the city water supplies of the major cities of Bangladesh. 102 water samples collected from 14 city supplies were analyzed and these samples contain fluorine in the range of 0.03 to 1.1 0 mg/L with a mean of 0.33 ± 0.21 mg/L. It was also observed that except the samples of Barisal, Dinajpur and Rajshahi, all other water samples analyzed contain a much lower amount of fluorine than the maximum permissible value for Bangladesh in drinking water, which is 1 mg/L. The mean concentration of fluorine in the samples of Barisal, Dinajpur and Rajshahi are respectively 0.79±0.01, 0.71±0.13 and 0.92±0.18 mg/L. For the 55 samples of Dhaka city supply the mean fluorine concentration is 0.31±0.17 mg/L and that of 9 samples from Chittagong city supply is 0.19±0.1 0 mg/L, which is the lowest among the 14 city supply samples analyzed in this study.

The fluoride levels in 304 water samples from different sources in Bangladesh were determined using the proton induced gamma emission (PIGE) method. Concentrations vary from 0.02 to 2.32 mg/L with a mean of 0.43 ± 0.40 mg/L In tube well water the concentrations range from 0.02 to 2.32 mg/L for 163 samples with a mean of 0.56 ± 0.48 mg/L. Surface waters contain the lowest amount of fluoride with a mean of 0.14 ± 0.10 mg/L for 23 samples. In rain water the mean fluoride content is 0.26 ± 0.13 mg/L, slightly higher than in surface water. The concentration of fluoride in 102 city water supplies ranges from 0.03 to 1.10 mg/L with the mean of 0.33 ± 0.21 mg/L These results indicate that the fluoride level in groundwater is, in general, lower than the maximum official permissible limit of 1 mg/L in drinking water set for Bangladesh.
