The average lung deposition (oral breathing) fractions of PM1 of HVOPM+NOx was calculated with the model presented by Rissler et al. [48] and compared to the calculated deposited doses of petroleum diesel from Wierzbicka et al. [15]. The average mass, particle number and surface area concentrations of the respective exposures are given. All values are presented as mean ± 1 std. dev
