Interactions of animal age and particle size with deposition and retention of inhaled 51Cr-labeled microspheres
Description
Newborn, juvenile, weanling, and adult rats were exposed to aerosols of 51Cr-labeled microspheres with AMADs of 0.91, 1.4, 2.3, 3.4, and 4.4 μm. Alveolar deposition was negligible in newborn rats for all particle sizes, and decreased to less than 6% at an AMAD of 2.3 μm in juveniles and weanlings, and an AMAD of 3.4 μm in adults
