| Research Abstract |
The measurements of the lead isotopic ratio and the multielement mapping of human nails and hair by LA/ICP-MS were investigated. The possibility that the time fluctuation of lead isotopic ratio is followed by the measurement of the nondestructive hair along the growth direction was able to suggested. The lead isotopic ratio of nail was inferior to hair in precision. It seems to be useful when the human hair and nail are used complementary. Mapping measurement of Mg, Al, S, Cr, Co, Cu, Zn, Se, and Pb were possible in the hair sample. The determination of contents of these elements in the human hair was unsuccessful using the skim milk powder sample as a standard reference material.
