Not sure exactly why you’re getting downvoted as that was essentially the point of the article:
Flame retardant chemicals off-gas or leach from the seat and interior fabrics into the air, — especially in hot weather, when car interiors can reach 150 degrees Fahrenheit.
Advocates argue that the risks of these chemicals outweigh the benefits.
But health researchers have found that the average U.S. child has lost up to 5 IQ points from exposure to flame retardants in cars and furniture. And adults with the highest levels of flame retardants in their blood face a risk of death by cancer that is four times greater than those with the lowest levels, according to the Journal of the American Medical Association.
