Exposure to air pollution during pregnancy may increase the child's risk of behavioral issues, according to one study.

Researchers in New York and Los Angeles studied more than 250 pregnant women. Once born, the children were tested for more than 10 years.

Researchers discovered that those exposed to the most air pollution were more likely to exhibit memory issues and ADHD.
