Autism spectrum disorder and other neurodevelopmental disorders could be triggered by air pollution, a new study suggests. Researchers and other experts speak about the potential risk.
Autism spectrum disorder and other neurodevelopmental disorders could be triggered by air pollution, including the type emitted in car exhaust, a new study suggested — though it had some limitations. The review, led by Hebrew University of Jerusalem, analyzed multiple studies related to autism and cellular activity. The findings were published in the journal Brain Medicine.
They also investigated four different ways in which these particles could impact the fetus. Those four ways were neuroinflammation, oxidative/nitrosative stress , epigenetic modifications and disruptions to certain neurotransmitters, according to the study.
In the U.S., autism affects one in 36 children, or about 2.3%, as of 2024, according to statistics from the Centers for Disease Control and Prevention . This is an increase from one in 44 children two years ago. Air pollution is also on the rise, affecting approximately 131.2 million people, or 39% of the U.S., as noted in the 2024 American Lung Association's State of the Air report. This is an increase of 11.7 million people from 2023.
