Abstract
Biological reference materials for elemental speciation were prepared at the National Institute for Environmental Studies. A new human hair reference material, prepared by cryogenic grinding using a ceramic disc mill, is in the process of certification for methyl-Hg and trace elements. Hijiki seaweed reference material was prepared for As speciation studies, primarily for use in the analysis of As(V). Scallop tissue reference material will be certified for arsenobetaine.
