Near-Road Traffic-Related Air Pollution: Resuspended PM from Highways and Arterials.

Recent studies suggest that the transportation sector is a major contributor to fine particulate matter (PM) in urban areas. A growing body of literature indicates PM exposure can lead to adverse health effects, and that PM concentrations are often elevated close to roadways. The transportation sector produces PM emissions from combustion, brake wear, tire wear, and resuspended dust.

Assessment of Traffic-Related Air Pollution: Case Study of Pregnant Women in South Texas.

Population groups vulnerable to adverse effects of traffic-related air pollution correspond to children, pregnant women and elderly. Despite these effects, literature is limited in terms of studies focusing on these groups and a reason often cited is the limited information on their mobility important for exposure assessment. The current study presents a method for assessing individual-level exposure to traffic-related air pollution by integrating mobility patterns tracked by global positioning system (GPS) devices with dynamics of air pollutant concentrations.
