We do everything possible to keep our kids safe. But what do you do if the air they breathe is hurting them? Two new studies have found an association between relatively low levels of air pollution and children's risk of autism spectrum disorder.
One study studied 132,000 births in Canada from 2004 to 2009. Researchers concluded there was a link between exposure to oxide from car exhaust during pregnancy and greater incidence of childhood ASD.
The second study 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. While it's a small increase if large populations are exposed, it could affect many children.
"It confirms some previous research and suggests that an association between autism and air pollution should be studied again," Lynn Singer told Healthline. However, neither study proved that air pollution is causing ASD. The researchers have only found that children in an area with air pollution are at greater risk. This study's findings actually tell us we should try our best to protect our environment and to protect ourselves.
