Computations of aerosol deposition as affected by (i) aerosol hygroscopicity, and (ii) human age, have been done using a validated theoretical model. The behavior of inhaled H2SO4 particles subsequent to water vapor uptake significantly influences their relative spatial distribution patterns within human lungs. These observations must be accounted for in risk assessment protocols since compartments of the lung have distinctive clearance processes and reactions to toxic materials. Calculations also establish that subject age is a critical variable to incorporate into health effects studies. This is of particular importance since children are a potentially sensitive subpopulation of concern related to inhalation exposures to airborne contaminants.
