Nanoparticle characteristics

Agglomerate size [nm] Mass [μg/m 3 ] Particle number [#/cm 3 ] Surface area [nm 2 /cm 3 ]
15.3 (1.26) 179 (107–252) 3.8 × 106 (2.6 - 5.0) 6.72 × 109 (3.97-9.49)
410 (1.43) 167 (147–187) 2.0 × 104 (0.43 - 3.7) 2.33 × 108 (0.28-2.61)

Particle size is given as count median diameter (CMD) with the geometric standard deviation (GSD). Mass, particle number and surface area shown as mean with a 95% confidence interval.
