Research

The following studies reflect a range of research about pollution from school buses and children's exposure to this pollution. EPA does not endorse these studies. EPA and others are doing additional work to further study exposure to pollution from school buses.

Co-funded: California Air Resources Board and EPA/with University of California

Overview/Purpose

Identify children's exposures to exhaust from school buses

Obtain measurements of in-bus and near-bus pollutant concentrations during normal school bus operations across the full range of anticipated conditions (e.g., following high emitters, in caravans, driving on streets and on freeways).

Identify commuting situations resulting in high-end exposures

This February 2001 study from NRDC and the Coalition for Clean Air shows that children who ride a diesel school bus may be exposed to up to four times more toxic diesel exhaust than someone traveling in a car directly in front of it.
