Figure 7
XRF maps with localized POI and XANES spectra at the Zn K-edge (patients 2 and 8). A reference spectrum of zincite (ZnO) is also shown as comparison. (a, b) Patient 2, the four spectra are similar and consistent with endogenous Zn. (c, d) Patient 8, three spectra are consistent with exogenous Zn (ZnO), and one with endogenous Zn (POI 4). |
