From: Equivalent titanium dioxide nanoparticle deposition by intratracheal instillation and whole body inhalation: the effect of dose rate on acute respiratory tract inflammation

Medium

Concentration

Size distribution

Air

33 ± 4 mg/m3

MMAD 800 nm, 1.4 GSD

CMD 900 nm, 1.8 GSD

Saline

80 μg/mL

DLS z-avg 1350 nm, peak range 800–1700 nm

LDS mean 6363 nm, peak range 900–11000 nm

  1. MMAD, mass median aerodynamic diameter; CMD, count median diameter; GSD, geometric standard deviation; DLS, dynamic light scattering (intensity mode); LDS, laser diffraction spectroscopy (volume-based). DLS and LDS are representative of 3 separate runs.
