Comparison of mineral content of bottled spring and mineral waters marketed in Turkey

Abstract

Drinking water is the most indispensable substance for humans. Bottled drinking waters arepreferred over tap water with the belief that they are more nutritious, better quality, more deliciousand safe in terms of health. Therefore, the Turkish bottled (spring and mineral) water market hasexperienced a continuous growth since 2003, as in the whole world. This study focuses oncomparing the common mineral cation calcium (Ca2+), magnesium (Mg2+) and sodium (Na+)content of twenty one popular bottled spring and mineral water brands marketed in Turkey by usingan inductively coupled plasma optical emission spectrometry (ICP-OES). The averageconcentrations of Ca, Mg and Na analyzed in bottled spring and mineral water samples were foundas 14.9, 24.1 and 8.2 mg/L and 147.9, 44.3 and 117.3 mg/L, respectively. This comparison confirmsthat bottled natural mineral water has better quality in terms of major nutrient minerals than bottlednatural spring waters.
