Styrene Will Not Be Added to California’s Prop. 65 List

California EPA’s Office of Environmental Health Hazard Assessment (OEHHA) has withdrawn styrene as a potential addition to the list of substances known to the state to cause cancer by means of the Labor Code mechanism. In 2009, a state judge tentatively enjoined its listing after determining that no known evidence supported a finding that styrene is a carcinogen and that its designation as such would likely have a devastating effect on the industry. Widely used in food packaging, styrene plastics are apparently crucial to the transportation and sale of strawberries, raspberries and blueberries, state industries worth more than $1 billion. The court further ruled at the end of 2012 that OEHHA’s reliance on the International Agency for Research on Cancer’s conclusion that styrene is “possibly carcinogenic to human” was insufficient to justify its listing. OEHHA has not reportedly appealed the decision. See InsideEPA.com, February 21, 2013.
