Abstract

For sub-25 nm particles, the agreement of the number-size distributions based on TEM measurements of solid particles and SMPS measurements of total particles suggests a large fraction of sub-25 nm particles were solid. The presence of solid sub-25 nm particles may be of public health interest given the potential for deposition in the alveolar region of the lung21 and the large relative number of surface molecules.22 Nanoparticle emissions analyses for a large set of engines would be needed to estimate the potential contribution from the DISI vehicle portion of the fleet.
