Curbing school bus emissions improves children's health -- study

摘要

Reducing air pollution from school buses makes children healthier, according to a new study by researchers from the universities of Washington and Michigan. The study examined the impact of clean diesel technologies and fuels on concentrations of air pollution within buses and found that lower pollution levels resulting from the technologies improved lung function in children, particularly among asthmatics. They estimated that the results mean that there could be 14 million fewer school absences a year. "The national switch to cleaner diesel fuel and the adoption of clean air technologies on school buses lowered concentrations of airborne particles on buses by as much as 50 percent," said Sara Adar, the study's lead author and an assistant professor of public health at the University of Michigan. "Importantly, our study now shows measurable health improvements from these interventions, too.
