Titanium dioxide in nanoparticle form (TiO2-NP) is used in many industrial and commercial applications. ANSES was asked to define a toxicity reference value (TRV) for this substance as part of its national mission to develop health reference values. Following an in-depth analysis of all the available toxicity data, the Agency is recommending a chronic TRV by inhalation for the P25 form of TiO2-NP of 0.12 µg/m-3.
