Abstract

Human daily activity patterns and age-scaled anatomical models are used to calculate expected daily particle deposition rates for adults and children. Daily doses in µg kg-1 per day per µg m-3of air of particles in various sizes are calculated for the N-P, T-B and P regions of adults that work indoors at a low level of exertion or that work more heavily outdoors and for active children. Higher doses are seen for higher levels of activity, as expected. Whether or not children’s doses are larger than those of adults depends on particle size and region of the respiratory tract considered. © 1994 The British Occupational Hygiene Society.
