Particle size distributions. A) SEM image of SPIO nanoparticle agglomerates taken from MOUDI stage #7 (ECD = 233 nm); B) SMPS particle size distribution used to determine the CMD; C) Mass-based particle size distribution measured using nano-MOUDI (μg) and derived from SMPS (μg/m3). The MMD was 207 nm measured by nano-MOUDI and 171 nm when derived from SMPS data using a particle density of 5 g/cm3.
