Chemical composition and heavy metals in bottled mineral drinking waters in Bandar Abbas

Introduction: In recent years, attraction toward drinking bottled mineral water hasincreased. Therefore, chemical composition and safety of these waters considering traceelements and heavy metals should confirm the national or international standard limits. Theaim of this study was to evaluate and comparison of the mineral and heavy metalcomposition of bottled waters in Bandar Abbas with Iranian national standard range.Methods: A total of 125 samples from 25 bottled mineral water brands were analyzed for17 elements including Zn, Cu,Ca, Mg, Na, K, Al, Mn, As, Pb, Cr, Se, Cd, Co, Ni, Mo, Bausing ICP-OES technique. Concentrations were compared to the desirable and permissiblelimits of Iran national standard.Results: Zn, Cu, Ca and Mg were lower than desirable limits. Na concentration in allbrands was lower than maximum permissible limit. Concentrations of Cr and Se werehigher than maximum permissible limit in 7 brands. As, Pb, Cd, Co, Ni, Mo and Baconcentrations were lower than maximum permissible limit in all brands.Conclusion: The results showed that the studied mineral waters could not provideclinically important dietary intake of Ca, Mg, Cu and Zn. Low Na concentration was aproper characteristic. Except for 7 brands with high Cr and Se concentrations, other bottledmineral waters were safe for daily intake.
