Titanium Dioxide (TiO2 - World Health Organization
monographs.iarc.who.intThe percentage of titanium dioxide manufactured as nanoparticles has been estimated as 2.5% in 2009 and about 10% by 2015 (Robichaud et al., 2009). Liao and colleagues transformed mass exposure data from two recent epidemiology studies to surface area measurements for nano-titanium dioxide, calculating that 1 g titanium dioxide had 50 m2 surface.
