Background: Fluor is an anion found in water and soil, however, its concentration is greatly varied in different sources of drinking water. Since our body requirement to Fluor is mainly achieved through drinking water, determination of its concentration is of utmost importance. The present study was conducted to determine the Fluor concentration of drinking water of Kashan in 1999.
Materials and Methods: It was a descriptive study. All sources of drinking water in Kashan were examined. With respect to its seasonal changes, sampling was performed twice (In two different seasons). Sampling and the related examinations were performed according to the standard methods.
Results: 201 sources were sampled twice. The maximum and minimum concentration of Fluor were revealed 1.2 and 0.25 mg/dl, respectively, meanwhile the mean concentration of Fluor in spring and fall were 0.65 and 0.64 mg/dl, respectively. 50.6% of sources had standard Fluor concentration. Fluor concentration was higher in plateau areas.
Conclusion: Some water sources in Kashan have not met standard Fluor concentration, thus, we suggest addition of Fluor to their food cycle. Fluor-enriched mouthwashes are highly recommended for their children.
