Titanium dioxide, a potentially harmful substance, was sprayed on the new technology building near Parking Lot 6. The International Agency for Research on Cancer classified titanium dioxide as a group 2b substance, possibly carcinogenic to humans. The substance is widely used to provide whiteness in products such as paints, plastics, papers, and toothpaste. It is also used as a ultraviolent blocker in skincare products, cosmetics, and almost all sunscreen.
The IARC based its findings on a test done with rats which where subjective to environments containing high concentrations of two forms of titanium dioxide, pigment grade powder and ultra fine dust. It found that exposure caused impaired lung clearance, cell injury, fibrosis(scarring), mutation and lung cancer.
These test have been equaled to the same amount of exposure of people working in high concentrations like when milling or packing this substance, in which some cases of lung cancer have occurred.
Despite being banned in Europe and Canada, titanium dioxide has beneficial qualities. According to Bio Shield, a company which sells this product, when exposed to light, indoor or outdoor, it takes on a bacterial reduction quality, not only killing bacteria but decomposing the cell itself. This resilient and long term effect is three time stronger than chlorine. Which is why it is used in hospitals.
The deodorizing effect accelerates the breakdown of any volatile organic compounds, such as cigarette smoke, urine, fecal matter, and gasoline.
It also has a self cleaning quality for exterior walls, reducing oily components from automobile exhaust.

Titanium Dioxide has been classified as "Possibly Carcinogenic to Humans" - yet still appears in the formulation of many well known household, and even personal care products such as toothpaste!
