Effect of initial particle size (highly soluble, dissolution rate of 1 × 10−4 g/cm2 per day; density of 3 g/cm3) on time to steady state in the alveolar region (Panel A) and dissolution from alveolar and interstitial/lymph compartments (Panel B). Above results are for 1 µg deposition per day in the alveolar region and are invariant to/with a person’s age or activity level
