Researchers at the University of Pittsburgh think they have found a link between prenatal and early life exposure to air pollution and autism. The study focused on 217 families with children on the autism spectrum.
Autism now affects one in 68 children in America. That is up nearly 800 percent in the last 20 years. Principal investigator Evelyn Talbott said her research found exposure to increased levels of chromium and styrene increased the risk of autism by 1.4 to two times.
