The Japan Society for Analytical Chemistry has developed two new certified reference materials, (CRMs) JSAC 0402 and JSAC 0403, for analyses of trace inorganic components. The materials were certified for the concentrations of 13 elements (Cd, Pb, As, Cr, Se, Cu, Zn Ni, Mn, V, Hg, B and F) and for the concentrations obtained by the elution analysis (issued by Ministry of Environment) of 7 elements (Cd, Pb, Hg, As, Se, F and B). For certifying analytical data, an interlaboratory comparison exercise, in which 17 laboratories had participated, was carried out. In a statistical analysis of data that reported from participants, z scores in the robust method were applied to reject outliers, followed by the usual statistical procedure. The presented CRMs are expected to be useful for the quality assurance and the quality control in the analysis of inorganic pollutants in soil.
