As we’ve recently reported, air pollution is increasingly becoming a health risk, especially for children. And recent studies, linking air pollution and autism, continue to confirm this.

As Healthline reports, there have been multiple studies recently claiming that air pollution may increase the risk of autism in children. However, there’s a strong emphasis on “may,” since the research has found that children in areas with air pollution are at a greater risk of autism, but none have proved that air pollution actually causes autism spectrum disorder (ASD). Healthline has more:

One study, published in JAMA Pediatrics, studied 132,000 births in Vancouver, Canada, from 2004 to 2009. Researchers concluded there was a link between exposure to nitric oxide from car exhaust during pregnancy and greater incidence of childhood ASD.

The second study, published in Environmental Epidemiology, observed more than 15,000 infants born in Denmark between 1989 and 2013. It found that air pollution exposure during the first months of life and later was also associated with ASD.

“The study showed a small increase in autism for infants exposed before birth to one of the pollutants: nitric oxide. While it’s a small increase, if large populations are exposed, it could still affect many children,” Lynn Singer, PhD, professor of population and quantitative health sciences, pediatrics, psychiatry, and psychology at the School of Medicine at Case Western Reserve University in Ohio, told Healthline.

This concern over children’s exposure to air pollution is becoming a common thread in international news headlines. Last month The Guardian reported about diesel emission fears in London, which are prompting families to move outside of the city, while another recent study (by the Energy Policy Institute at the University of Chicago) linked air pollution and a lower life expectancy.
