Synchrotron XRF images of hair cross-sections illustrating spatial distribution of Hg (a–d) and Zn (e,f) on the hair exposed to HgCl2 (a,e), hair belonging to ICL worker ID 14 (b,f), hair belonging to ICL worker ID 8 (c) and hair exposed to Hg0 (d). (g) XRF generated tomography of Hg (red) and Zn (blue) distribution in the selected hair of ICL workers suggesting adsorption of Hg on the outer layer of the hair. Zoomed in section of the hair from ICL 4 and 8 shows some deposits of Hg in the root of the hair. (h) Synchrotron generated XANES LIII spectra of Hg in the selected standards and hair/toenail samples (1: Hg0, 2: Hg(I) sulfate, 3: Hg(II) sulfate, 4: Hg(II) sulfide, 5: HgCl2, 6: MeHgCl, 7: MeHgGS, 8: Hg(GS)2, 9: hair and toenails) and calculated bond length between Hg and its bonding atom in the hair exposed to HgCl2 and selected hair sample of ICL workers (i).
