On the removal of air-borne droplets by the human respiratory tract: II. The nasal passages
- 45 Downloads
Theoretical considerations lead to the calculation of the amounts of air-borne materials removed by the various regions of the human nasal passages. These calculations are presented and discussed in the light of available data and lead to the conclusion that impaction due to inertia is the principle factor in the removal of the air-borne particles of diameters greater than one micron.
