Long-term exposure to high concentrations of fluoride is associated with several adverse effects on human including dental and skeletal fluorosis. We studied all the groundwater wells located in rural areas of Khaf city, Razavi Province, northeastern Iran between 2009 and 2010. Fluoride concentration of water samples was measured by SPADNS method. We found that in rural areas the fluoride concentration ranged from 0.11 to 3.59 ppm-the level was less than the permissible limit in 31% of studied samples, higher than the permissible limit in 4% of the samples, and within the optimum limit of 1 to 1.5 ppm in 65% of water samples.
长期暴露于高浓度氟化物会对人体产生多种不良影响，包括牙氟中毒和骨氟中毒。我们研究了2009年至2010年间位于伊朗东北部拉扎维省哈夫市农村地区的所有地下水井。通过SPADNS法测量水样中的氟化物浓度。我们发现，农村地区的氟化物浓度范围为0.11至3.59 ppm——在所研究的样本中，31%的样本浓度低于允许限值，4%的样本高于允许限值，65%的水样浓度在1至1.5 ppm的最佳限值范围内。
