Fig. 5.1. Deposition of dust in the respiratory system. The percentage of activity or mass of an aerosol which is deposited in the N-P, T--B and P regions is given in relation to the Activity Median Aerodynamic Diameter (AMAD) of the aerosol distribution. The model is intended for use with aerosol distributions with AMADs between 0.2 and IO pm and with geometric standard deviations of less than 4.5. Provisional estimates of deposition further extending the size range are given by the dashed lines. For an unusual distribution with an AMAD of greater than 20 I&m,complete deposition in N-P can be assumed. The model does not apply to aerosols with AMADs of less than 0.1 m.

T._, and compartmental fractions, F ._, are given in the tabular portion of the figure for each of the three classes of retained materials. The values given for D N_prDT_~ and D, (left column) are the regional depositions for an aerosol with an AMAD of 1 pm.
