Schools are often put near major highways for transportation ease. However, researchers say that could be harming kid's health.

A new study shows many schools are sitting in "air pollution danger zones.


University of Cincinnati doctors mapped 8-thousand schools in 9 cities including Philadelphia.

They found one- third of all schools are within a quarter mile of major highways.

Kids spend a third of their time in school.

The lead researcher says new schools should be built away from big highways, and existing ones may need better air- filtration systems.
