School buses spew pollution into young lungs

Reducing school bus emissions could be a cost-effective way to cut children’s exposure to diesel fumes. Researchers reached that conclusion after finding that school bus passengers may inhale heavy doses of the vehicle’s pollution.

To understand school buses’ effects on air quality, Eduardo Behrentz of the University of California, Los Angeles and several colleagues drove six buses of various ages on a total of 16 runs along actual routes in and around Los Angeles.
