Abstract

Concentration of total dissolved solid (TDS), nitrate and fluoride in 24 different brands of Iranian bottled water were studied. A total of 78 bottle water was analyzed for TDS, NO3-and F- according to standard methods. Also, results were compared to Iranian, World Health Organization (WHO) and Environmental Protection Agency (EPA) drinking water standards. The mean concentrations of F- in all examined water samples were lower than acceptable ranges. In three brands the concentrations of nitrate were higher than Iranian legislations (NO3- ≥45 mg/l as NO3-). In addition, the mean concentration of TDS in 9 brands were higher than 500 mg/l (Iranian legislations) and in all brands were within the appropriate WHO guidelines values.

 

Key words: Bottled waters, total dissolved solid, nitrate, fluoride, Iran, drinking water.
