Assessing the Chemical Components of some Iranian Brands of Bottled Water

Aims Bottled water is widely used in many countries and more than 100 different brandsof bottled water are produced in Iran. The aim of the present research was to assess thechemical compound of some Iranian brands of bottled water and compare them with themention information on their labels.Instrument & Methods This descriptive study was performed during March to December2012 on the 16 brands of bottled water produced in Iran. Random sampling (10 samplesfor each brand) was done by buying 1.5liter bottled water with different brands from thesupermarkets in Kashan City, Iran. The concentration of Na+, K+, F-, NO3-, SO4-2 and Cl- andthe pH of bottled water samples were measured. Data were analyzed by SPSS 16 softwareusing independent T test.Findings The mean concentration of NO3- was 1.70±2.52mg/l, Na+ was 8.44±8.76mg/l,K+ was 0.11±0.53mg/l, SO4-2 was 15.15±12.49mg/l, Cl- was 42.30±33.84mg/l and F- was1.02±1.88mg/l in all samples of 16 brands of bottled water. The highest concentrationof NO3- was seen in brand 12 (9.55±2.76mg/l), Na+ in brand 6 (32.18±12.60mg/l), K+in brand 13 and 4 (1.86±0.76mg/l), SO4-2 in brand 6 (40.53±8.90mg/l),Cl- in brand 16(88.73±13.80mg/l), F- in brand 13 (0.63±0.12mg/l). The pH of brand 12 (7.9±0.1) was thehighest among the samples.Conclusion The concentrations of Na+, K+, F-, NO3-, SO4-2 and Cl- of the studied Iranianbrands of bottled water are not higher than the national and international standards and thepH is in the acceptable range.
