This study monitors the elemental composition of different brands of bottled natural mineral waters marketed in Turkey and discusses compositional parameters. Natural mineral water samples were analyzed for cesium (Cs), rubidium (Rb), thallium (Tl), cobalt (Co), arsenic (As), chromium (Cr), lead (Pb), gallium (Ga), vanadium (V), silver (Ag), cadmium (Cd), uranium (U), thorium (Th), and molybdenum (Mo) by inductively coupled plasma mass spectrometry (ICP-MS). Method trueness was confirmed by using 1640A natural water certified reference materials purchased from Laboratory of the Government Chemist (LGC). The linearity, limit of detection, limit of quantification, repeatability, and recovery (%) were assessed. Method validation data and results obtained from the certified reference material suggested that the method could be applied to determine elemental contaminants of the samples. Cd, Tl, Ag, and Th could not be determined (< LOD) in the samples. Pb, Cs, Co, Rb, Ga, V, U, As, Cr, and Mo were determined in samples. The results were compared with elemental standards for natural mineral waters set according to the World Health Organization and United States Environmental Protection Agency, and the concentrations of all metals did not exceed these values.
