Dr. Ann Blake of EPHC and Debbie Raphael, Director of the San Francisco Department of the Environment, and former Director of Cal/EPA’s Department of Toxic Substances Control, co-authored a piece for the Huffington Post’s World Cancer Day series February 4, 2015. The article highlighted the urgent need for a focus on cancer prevention by reducing or eliminating exposures to carcinogenic chemicals in our daily lives, and described the precautionary approach embedded both in San Francisco’s ground-breaking Precautionary Principle Ordinance within the city’s Environment Code, as well as the state of California’s Safer Consumer Products Program.
