Abstract
Bottled drinking water consumption has increased in recent years. Determination of chemical composition of these waters is important interm of public health. Therefore, the objective of the study was to determinenitrate, fluoride, chloride and sulfate levels in bottled waters sold in Sanandajcity during summer and winter of 2012, and their comparison with Iranian and international drinking water standards.Samples were purchased and collected randomly from supermarkets in which 10 types of different brands were examined. The names of the brands are denoted as A to J. The volume of each bottle was 1.5 Lit.Ion Chromatography was used to determine levels of different elements in samples. The results of the study showed that nitrate, fluoride, chloride and sulfate levels in the samples were 0.84-7.69, 0.04-0.32, 0.64-30.29 and 0.26-58.73 mg/l, respectively. levels of nitrate, fluoride, chloride and sulfatein the bottles were lower than drinking water standards, but the written levels on the labels had no enough precision.
