Absolute aerosol deposition differed according to lung lobe mass. Differences in concentration of deposited germs were low between lobes, after exposure to space aerosols, and average germ concentrations in anterior lobes were higher than those in basal lobes only in mini piglets. Concentrations of aerosols deposited in anterior lobes were higher, when mask aerosols were used. Intratracheal application was followed by highly differentiated deposition in pulmonary lobes, with high local concentrations per gram of tissue.
