The Japan Society for Analytical Chemistry has developed two new certified reference materials (CRMs) for dioxins, coplanar PCBs and 1〜10 chlorinated PCB homologues. A project team was organized to prepare 2 kinds of river sediment and to certify the concentration of dioxins and so far. An interlaboratory comparison test was performed by participation of 16 laboratories. In statistical analysis, z-scores in the Robust method was applied to reject outliers and followed by usual statistical procedure. The presented CRMs are expected to be useful for quality assurance and quality control of dioxins analysis.
