The study was conducted in California homes, because furniture manufacturers use flame retardants in products sold throughout the U.S. in order to meet California's stricter flammability standard. Many health experts have called on California Governor Jerry Brown to make good on his promise to amend the requirement, which affects the health of people around the country.
This study complements a separate study, also being published in Environmental Science & Technology today (Nov. 28), that found many potentially problematic flame retardants in couches. Both studies break new ground by revealing the wide range of flame retardants in use. The Silent Spring Institute study demonstrates that flame retardant chemicals in couches and other products wind up in house dust at levels of health concern.
Two PBDE formulations have been phased out due to health concerns, but other flame retardants with considerable evidence of toxicity, such as chlorinated organophosphates and HBCYD, appear to remain at high or increasing levels of use. Every home tested had HBCYD, which was prioritized by regulators in the US and Europe because of its persistence and concerns about human reproductive, neurological, and developmental effects.
Other flame retardants being used as replacements for PBDEs have unknown health implications. The study found that levels of chemicals in Firemaster 550 increased from 2006 to 2011, likely because it is being used as a replacement for PentaPBDE, which was phased out.
"When one toxic flame retardant is phased out, it's being replaced by another chemical we either know is dangerous or suspect may be. It's not comforting to swap one hazardous chemical for its evil cousin. Instead, we should test chemicals before they are allowed on the market," said Dr. Julia Brody, executive d
