Is Air Pollution Contributing to the Rise in Autism?
"Nobody knows what exactly causes autism," writes Ariel Schwartz. "Genetics are probably a piece of it. Vaccines are not. A new study says there’s another trigger: air pollution."
"The study, published this week in Environmental Health Perspectives, tested the idea that air pollution while in utero can contribute to autism in children. It’s a hypothesis supported by past research--other studies have found a link, but only conducted their research in three states. This most recent study looked at children in all 50 states. The result: exposure to air pollutants--including diesel, lead, manganese, mercury, and methylene chloride--in utero increases the risk of autism, especially in boys."
