title: Validation Study on a Method for Simultaneous Quantification of Elements in Mineral Water and Surveillance of Element Concentrations.
abstract: A validation study was performed on the Japanese official method to determine several elements (B, Cr, Mn, Cu, Zn, As, Se, Cd, Ba, Pb) in mineral water simultaneously using ICP-MS. The trueness, repeatability and reproducibility of the method were estimated to be in the ranges of 95-106, 0.2-1.4 and 0.4-4.2%, respectively. The values of every performance parameter fulfilled the requirements in the guidelines announced by the Ministry of Health, Labour, and Welfare of Japan, and the validity of the method was confirmed. The concentrations of the elements in mineral water products purchased from Japanese markets in 2013 and 2014 were surveyed using the method. All products met the specifications defined in the Japanese Food Sanitation Law. No clear relationship between the element concentrations and the survey year or the producing country was found.
