Figure 8From: Titanium dioxide nanoparticles induce oxidative stress and DNA-adduct formation but not DNA-breakage in human lung cells Relative values of 8-OHdG adduct formation in IMR-90 cells after treatment with titanium dioxide and hematite nanoparticles for 24 h. TiO2-NP were found to generate 1 and 1.1 ng/ml of 8-OHdG adducts at the concentrations of 5 and 10 μg/cm2, respectively, whereas hematite NP failed to induce any 8-OhdG adducts in IMR-90 cells.Back to article page
