Kinetics of particle retention in the human respiratory tract.
A mathematical model of retention of insoluble aerosol particles penetrating the lungs during inhalation has been described. Based on data of the streams of deposited particles and their residence times in the subsequent generations of bronchial tree the retention dynamics of particles with diameters 5, 1 and 0.01 microns in the air-spaces has been determined.
