Measurements of the total and regional deposition of inhaled particles in the human respiratory tract
PC Emmett, RJ Aitken, WJ Hannan - Journal of Aerosol Science, 1982 - Elsevier
The total and regional deposition of monodisperse aerosols in the human respiratory tract
has been measured in 12 healthy subjects breathing through the mouth. Radioactively
labelled polystyrene particles in the aerodynamic diameter range 3.5–10.0 μm were
employed. The total deposition results are similar to those reported by Stahlhofen et
al.(1980), showing only a slight progressive increase with particle size, from a mean fraction
of 0.79 of the inhaled aerosol at 3.5 μm, to 0.88 for 10 μm particles. The extrathoracic …
