Particle size distributions (Geometric Diameter, D g ) of ultrafine TiO 2 (A) and fine TiO 2 (B) aerosols generated by the inhalation exposure system. The ultrafine TiO2 aerosol has a primary mode at 100 nm and a secondary mode at 400 nm. The fine TiO2 aerosol has a primary mode at 710 nm and a secondary mode at 120 nm. These number-based size distributions were determined by combining the data from SMPS and APS.
