(CBS) - A new Harvard University study finds pregnant women who are exposed to high air pollution levels may be at increased risk of having an autistic child.

Researchers studied more than 25,000 women and found those who lived in locations with the highest level of diesel particles and mercury in the air were twice as likely to give birth to a child with autism.
