a
Urinary clearance rate for 3-OH BaP was visually estimated to minimize the difference between measured and simulated urine concentrations and maintain a ratio of ±2 for all individuals with a mean of 1.0.
b
The fraction deposited estimated using a MMAD of 0.3 μm and GSD of 3.0 (treated as a polydisperse particle by MPPD).
