This study suggests adverse effects of exposure to aerosols containing a high proportion of nanoparticles of TiO 2 and Fe oxides with signs of inflammation and genotoxic/carcinogenic effect due to the oxidation of nucleic acids. As TiO2 and Fe oxides are of low toxicity, the effects may be attributed to the nanopar- ticles. The diameter of inhaled particles seems more important than the chemical composition, because nano-sized particles are able to cross cell membranes, unlike chemically identically bulk TiO2 and Fe oxides. As the non-soluble particles are removed from the lungs with a very long half-life, EBC appears a preferred biological fluid for the evaluation of their deleterious effect.
