More Research Links Autism to Prenatal Exposure to Air Pollution

A new study adds to the growing body of evidence linking autism to air-pollution exposure during late pregnancy. In particular, the researchers looked at exposure to particulate matter – the kind of pollution associated with traffic. The findings, by researchers at the University of Wisconsin-Milwaukee, appear this week in the journal Epidemiology.
