How fire retardants get into us

People end up with fire retardants in their bodies mainly by inhaling or swallowing dust. Scientists believe that small children may have higher exposures to fire retardants because they spend more time on the floor, where dust contaminated with these chemicals accumulates. A 2012 study by Duke researchers found that the levels of PBDE flame...
