Recent air pollution and epidemiological findings suggest that harmful vehicle-related pollutants and their associated adverse health effects concentrate within a couple hundred meters of heavily traveled freeways and thoroughfares. We’re just beginning to understand the health and economic costs of such localized effects, and we still know little about who is exposed to these pollutants.
