Abstract
Instrumental neutron activation analysis (INAA) has been employed in t he investigation of mass balance for mercury species analysis in the a nalytical process. A new human hair reference material (IAEA-085) was analyzed for methylmercury using a solid/liquid extraction procedure, with samples of extracts, residues, and untreated samples being analyz ed by INAA. The certified reference material NIES CRM No. 13, human ha ir, was analyzed in parallel. From the results obtained through the ma ss balance studies, it was found that the extraction procedure was qua ntitatively complete, and that there was no difference between the mas s balance of Hg and the total Hg in the untreated materials.
