Laser ablation inductively coupled plasma mass spectrometry (LA-ICM-PS) generated elemental maps of BALF cell samples from rats at 3Â days post-exposure to 10Â nm iridium aerosol (A) and 589Â days post-exposure to 35Â 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 comparison
