Study: Possible link between air pollution, autism

BOSTON (NEWSCHANNEL 3) - Researchers from the Harvard School of Public Health have released the details of a study that suggests there is a link between exposure to air pollution during pregnancy and autism.

The study looked at 25,000 women and found those exposed to high levels of air pollution while pregnant were twice as likely to have a child with autism.

Experts say the findings do not mean that pollution causes autism, but may be another risk factor.

Between 20 and 60 percent of the women in the study lived in areas where pollutants were a problem.
