Abstract
Deposition of diesel exhaust particles in the human respiratory tract is calculated in terms of the equivalent mobility diameter while accounting for the aggregate's number of primary spherules, Np, and its mass mobility fractal dimension. The size and shape of the soot particles studied correspond to emissions from diesel engines under different loading conditions. The aggregate's morphology, characterized by the aggregate mass mobility fractal dimension Dfm, is shown to significantly affect its age- and ventilation-specific deposition patterns in the human respiratory tract and hence, the exposure experienced by the receptor. Reporting respiratory tract deposi...
