Abstract

The fluoride level in N.W. of West Azarbayedjan in the 6000 Km2 area of Bazargan –Poldashat axe, is dangerously high and far above standard. Although, <1.5 mg/l of fluoride is beneficial to bone and dental development, but high intake normally gives rise to teeth mottling (dental FLUOROSIS) and skeletal problems (skeletal FLUOROSIS). In this study Fluoride concentration and distribution in 414 samples of various WATER BODIES (surface, ground spring and Qanat) and 48 rock and soil samples in the area were studied. Results demonstrated that most of the water sources are polluted by high fluoride levels and mean fluoride content is varying up to 6.8 ppm. Fluoride distribution and concentration along Sarysu and Zangmar Rivers are higher than 1.5 ppm, therefore all habitants of Bazargan–Poldasht and surrounding areas show strong dental FLUOROSIS. The fluoride concentration decreases from surface water to groundwater, spring water and qanat water, respectively. Although, fluoride levels are higher in water samples of basaltic areas, but it is not totally dependent on basalt, as it is also higher in non-basaltic lithologies. Rock and soil sample analysis indicated that fluorine level in basaltic rocks; soil and recent non-consolidated sediment; and limestone type formations varies between 217- 867ppm, 355- 932 ppm and 116-322 ppm, respectively. Although basaltic rocks and related soils are a major possible contributor of fluoride to WATER BODIES, but the epidemic presence of FLUOROSIS disease in the east of Turkey (Tendurek volcano vicinity) along Sarysu and Zangmar rivers implicates that flowing through this territory Turkey could be another very important source of fluoride supply to the N.W of Iran. Fluoride analysis also indicate that some WATER BODIES such as connates and springs bear a very low fluoride level, which with effective management, would suggest them as the best source of human consumable water for the mentioned area to strongly reduce the fluoride content.
