The rat is uniquely sensitive to the formation of lung tumours when exposed under conditions of particle overload to titanium dioxide (TiO2) and other poorly soluble low-toxicity particles (Levy, 1995). Although particle overload is observed in other experimental species, such as the mouse, it is only in the rat that a sequence of events is initiated that leads to fibroproliferative disease, septal fibrosis, hyperplasia and eventually lung tumours. Similar pathological changes are not observed in other common laboratory rodents, in non-human primates, or in exposed humans. Detailed epidemiological investigations have shown no causative link between titanium dioxide exposure and the risk of non-malignant respiratory disease in humans.
