Fraction deposited of cobalt monoxide (CoO) nanoparticles and lanthanum oxide (La2O3) nanoparticles as a function of time. Fractions deposited were calculated using the estimated effective density. Plots are presented for the nanoparticles suspeSnded in SABM. The fD for CoO nanoparticles is 0.8 and La2O3 nanoparticles is 1.0 for a 24-h in vitro exposure duration in both a 6- and 96-well exposure condition.
