Fig. 5From: Slow lung clearance and limited translocation of four sizes of inhaled iridium nanoparticlesLaser ablation inductively coupled plasma mass spectrometry (LA-ICM-PS) generated elemental maps of BALF cell samples from rats at 3 days post-exposure to 10 nm iridium aerosol (A) and 589 days post-exposure to 35 nm iridium-192 aerosol (B); showing light microscopy image of the cell sample analysed (a) and the distribution of iridium (b). Scales are in counts per second. Some areas have been highlighted to aid comparisonBack to article page
