The California Environmental Protection Agency’s Office of Environmental Health Hazard Assessment (OEHHA) intends to list Titanium dioxide (airborne, unbound particles of respirable size) as known to the State to cause cancer under the Safe Drinking Water and Toxic Enforcement Act of 1986.

In 2010, IARC published Volume 93 of its series, IARC Monographs on the Evaluation of Carcinogenic Risks to Humans (IARC, 2010b).  IARC concluded that (1) there is sufficient evidence in experimental animals for the carcinogenicity of titanium dioxide and (2) titanium dioxide is “possibly carcinogenic to humans” (Group 2B).
