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

Figure 7

Percentage of neutrophils 24 hr after single and repeated exposure to high dose TiO 2 at different dose rates. The percentage of neutrophils in BALF at 24 hr post inhalation (blue squares) or instillation (green circles) exposure plotted according to deposited dose rate (~0.21, repeated inhalation; ~0.71, high dose single inhalation; ~5,400, repeated instillation; and ~240,000 μg/min, high dose single instillation). Symbols are group means ± SE (n = 5).
