Laser ablation inductively coupled plasma mass spectrometry (LA-ICM-PS) generated elemental maps of kidney samples at 30 days post-exposure from rats exposed to 10 nm (A) and 75 nm (B) iridium aerosols; showing light microscopy image of the kidney section analysed (a) and the distribution of copper (a), iridium (b) and an overlay of the two plots (c) (copper, magenta; iridium, green; both, white) Scales are in counts per second. The copper distribution map is included to enhance visualisation of the localisation of the iridium; results from control animals (not shown) indicate no iridium is present and the same overall pattern of copper distribution
