This quasi-experiment examines the effect of state regulation of bus pollution on respiratory disease. Researchers compare emergency room visits for respiratory illnesses for patients living within several hundred feet of a bus route. Findings conclude that strict federal regulation of bus emissions was significantly correlated with reduced emergency room visits.
These findings suggest that reducing pollution is an important mechanism for improving public health. Specifically, regulating emission standards for public busses may significantly reduce respiratory disease.
