Measured vs. predicted lung burden. Ce and Ba contents were measured in explanted lungs of rats exposed to 0.1, 0.3, 1.0 or 3.0 mg/m3 CeO2 or 50.0 mg/m3 BaSO4 nanoparticles for up to 90 days. Predicted values (half colored symbols) were based on deposition fractions calculated via the MPPD model and expected first order elimination with half-times of 70 days (0.1–1.0 mg/m3) or 200 days (3.0 and 50.0 mg/m3)
