Researchers from the Harvard School of Public Health have found that women exposed to high levels of air pollution in their third trimester of pregnancy could be twice as likely to have an autistic child.
The study, published Thursday in Environmental Health Perspectives, shows that the risk of autism rises parallel with exposure to fine particulate matter during pregnancy, Bloomberg reports. Autism is believed to affect 1 in 68 U.S. children, and while the cause is unknown, recent studies suggest that it could start when specific brain cells do not properly mature inside the womb.
