International travelers experience adverse cardiopulmonary health effects even after short stay in polluted cities

Green Car Congress

For travelers who visit cities with high levels of air pollution, even a short stay leads to breathing problems that can take at least a week from which to recove, a new study led by researchers at NYU School of Medicine finds. Researchers then compared the health data against levels of air pollution collected from local government agencies.
