Pregnancy Pollution Exposure Linked to Increased Risk of Autism in Kids
Environmental pollution may play a role in the development of autism among children, according to the findings of new research.
In a study published online this week in the medical journal Environmental Health Perspectives, researchers indicate that pregnant women who were exposed to different types of pollution, including diesel particulates, lead, manganese, mercury and methyl chloride, were twice as likely to give birth to a child who would develop autism.
Air pollution contains toxins that are known to effect neurological functioning and can greatly impact a fetus’ development.

Change Healthcare Data Breach Impacts Millions of Customers
A massive Change Healthcare data breach exposed the names, social security numbers, medical and personal information of potentially 100 million Americans, which have now been released on the dark web. Lawsuits are being pursued to obtain financial compensation.

Andrea Roverts and her team of researchers from the Harvard School of Public Health then examined air pollution data provided by the U.S. Environmental Protection Agency (EPA) to determine the women’s exposure to the various pollutants while pregnant.
The results revealed that women living in locations with the highest levels of diesel or mercury pollution were twice as likely to have children with autism, compared to the women who lived in the areas with the lowest levels of pollution.
Children born to women living in areas with higher levels of lead, manganese, methylene chloride and combined metal pollutants had a 50 percent higher risk of having autism, again compared to children born to women living in areas with lower percentages of those pollutions.
Researchers also found that the link between pollution and autism was much stronger for boys than for girls. Previous studies have found an association between high levels of pollution and the development of autism in children, however those were limited to only a few geographical locations. This is the first national study on this scale to also find the link.
The authors of the study say they hope their findings will prompt others to focus on the association between pollution exposure to a fetus in utero to provide “stronger evidence that specific pollutants increase risk of autism.”
“A better understanding of this can help to develop interventions to reduce pregnant women’s exposure to these pollutants,” concluded the researchers.
