Evaluation of Trace Metals Found in Bottled Waters Sold in Izmir Turkey

Abstract

Within the scope of this work, 30 brands of bottled water sold in the Izmir Province of Turkey, were investigated for the levels of 6 trace metals (Al, Cr, Cu, As, Cd, and Pb) important for public health and drinking water quality Inductively Coupled Plasma Mass Spectrometry (ICP-MS) was used for the analysis of the trace metals. The highest metal ion concentrations obtained in the analyses of the samples was found to be 102.99 mu g Al/L, 1.80 mu g Cr/L, 40.22 mu g Cu/L, 11.36 mu g As/L, 0.08 mu g Cd/L, and 2.79 mu g Pb/L. The concentration levels revealed in this work were compared to the maximum concentration levels allowed by the WHO and other international standards, and as a result, a water sample of one brand, from the natural waters of Izmir, contained a total arsenic level (11.36 mu g As/L) exceeding national and international standards.
