Fig. 8From: Slow lung clearance and limited translocation of four sizes of inhaled iridium nanoparticlesIridium L(III)-edge μ-XANES spectra derived from iridium-rich pixels from samples of BALF cells shown in Fig. 7 and lung tissue at 1 day post-exposure to 10 nm iridium aerosol. The lung spectrum is the sum over 6 pixels and that for the BALF over 10 pixelsBack to article page
