Bromine, chlorine, and lead may be just a few of the chemicals in your child’s car seat, according to a recent study from the Ecology Center. The study tested 62 car seats sold at Babies “R” Us and Target, and found that over 30% contained significant levels of toxic chemicals that could adversely affect a child’s development; 60% contained brominated flame retardant, which can cause thyroid problems and memory impairment.
