Biodistribution of CeO2 nanoparticles in different organs. a Mass balance of recovered amount 1-day post exposure compared with calculated total inhaled amount of nanoparticles based on the filter pack measurements after the cascade impactor (equipped with a final cut-off of 0.5 μm), error bars show one standard deviation of the feces data. b Evolution of the total nanoparticles mass in the extrapulmonary organs compared with the inhaled mass of nanoparticles less than 70 nm in size, identified using the SMPS measurements. The three bar stacks represent the data from 15-min, 24-h, and 7-day post exposure, respectively, from left to right
