The article reports on a study of air pollution that is associated with traffic congestion in New York City. Researchers Ying Zhou and Jonathan Levy of the Harvard School of Public Health focused on the dispersion of traffic emissions in streets that have tall buildings on both which are referred to as urban street canyons. The "intake fraction" for air pollutants from mobile sources was used to determine the type and amount of pollution that people are exposed to.
