Dose response relationships for BALF cellular and biochemical parameters 24 hr post exposure to TiO 2 NPs. The numbers of cells (A), macrophages (B), and neutrophils (C), and LDH (D) and β-glucuronidase activities (E) 24 hr post inhalation (blue squares) or instillation (green circles) exposure to increasing deposited doses of TiO2 NPs. Values are group means ± SE (n = 5) and are represented as a percentage of respective controls. *, significantly different from corresponding controls; Φ, significantly different between exposure methods (p < 0.05).
