Authors
Abstract:
The purpose of this study was measuring concentration of fluoride in drinking water in Hamadan and Bahar cities, in west of Iran. By a pilot study sample size for Hamadan and Bahar were estimated 120 and 30, respectively. The results were compared with Iranian Standard. The results showed that concentration of fluoride in drinking water of Hamadan and Bahar were 0.198 and 0.6 mg/lit, respectively, which were less than the standard limit. The Shefe statistical test showed that the concentrations of fluoride in summer is less than others season and the difference was statistically significant (P < 0.001 ) .
