The Hill: “Tens of millions of Americans each day breathe in carcinogenic chemicals that are woven into the interiors of their cars, a new study has found. While opening a window can help reduce the risk, only reforms can keep people safe, researchers wrote in a study in Environmental Science and Technology.   Approximately 124 million Americans commute each day, spending an average of an hour in their cars. By federal law, the interior of these vehicles are required to contain flame retardants, or chemicals that make it harder for them to combust in a crash. These chemicals have been a legally mandated part of modern cars since the 1970s, when the National Highway Traffic Safety Administration (NHTSA) passed a law requiring their use. It’s arguable how effective this protection is.  Patrick Morrison, of the International Association of Firefighters, said in a statement on the study that these chemicals do little to prevent blazes — but instead simply make them “smokier and more toxic.”  What the study conclusively demonstrates is that any such protection comes at a price.  Virtually all cars investigated by Duke University researchers contained the chemical tris (1-chloro-isopropyl) phosphate, or TCIPP — which the U.S. National Toxicology Program is investigating as a potential carcinogen. Most cars also had two other phosphate-based flame retardants that the state of California is investigating as potential carcinogens: Those chemicals are tris (1,3-dichloro-2-propyl) phosphate (TDCIPP) and tris (2-chloroethyl) phosphate (TCEP).//”
