Lipid peroxidation induced by oral exposure to TiO2 NPs. A The concentration of malondialdehyde (MDA) increased significantly in liver tissue of rats in the TiO2 NPs treated groups (10 and 50 mg/kg) compared to the control group. B The concentration of malondialdehyde (MDA) also increased significantly in serum of rats in the TiO2 NPs treated groups (50 mg/kg)
