Over the last several years, nanoparticles have come under scrutiny for adverse health effects. Nanoparticles are ultrafine particles between 1 to 100 nanometers in diameter. (To put this in perspective, the average human hair is around 80,000 nanometers thick.) Because of their size, which can be engineered and manipulated at the atomic or molecular level, nanoparticles exhibit unique physical, chemical, and biological properties. Titanium dioxide is one of the most commonly produced nanoparticles in the world.

The National Cancer Institute tested TiO2 for possible carcinogenicity by the oral route of exposure by feeding rats and mice with TiO2 (size not specified) at doses 25,000 or 50,000 ppm TiO2 for 103 weeks. They concluded that TiO2 was not carcinogenic.Also, the study with rats fed diets containing up to 5 % TiO2 coated mica for 130 weeks showed no treatment-related carcinogenicity. Since the size and other TiO2 properties were not specified or determined, we cannot generalize this conclusion and we have to take into account other possible outcomes of this scenario in different exposure conditions (other size/crystalline structure of TiO2 etc.).
