Simultaneous analysis of seven inorganic anions (fluoride, chloride, nitrite, bromide, nitrate, phosphate and sulfate-ions) was carried out in two sets of 10 brands of mineral bottled waters (Iran) using ion chromatography (IC). Waters were sampled in autumn and winter of 2010. The obtained concentrations compared with the values on the labels. It was established that concentrations of the specified ions in tested waters were within the acceptable levels of the World Health Organization (WHO) and the United States Environmental Protection Agency (USEPA). Comparison of label values with our experiments showed that 11 label values had meaningful difference from the corresponding test values. The analysis of variance (ANOVA) revealed that sampling in autumn and winter periods did not influence the content of ions in water.
