California to Classify Styrene as a Carcinogen.


California regulators intend to list styrene under the state’s Proposition 65 as a chemical known to cause cancer.

The state Environmental Protection Agency’s Office of Environmental Health Hazard Assessment filed a notice of intent to list styrene last week, citing a 2011 report by the National Toxicology Program classifying it as “reasonably anticipated to be a human carcinogen.”

Styrene is used primarily in the production of polystyrene plastics and resins, and occupational exposure can occur in polystyrene factories and in the reinforced plastics industry. Exposure by the general population generally stems from indoor air that includes emissions from building materials, consumer products or tobacco smoke.
