N2 - The exposure metrics used in epidemiological studies that investigate traffic-related air pollutants were reviewed. Several metrics or their components were selected for in-depth analyses, and their strengths and weaknesses were described. This work was applied to a case study, an ongoing air pollution epidemiological study called the Near-road EXposures and effects of Urban air pollutants Study (NEXUS), which was designed to examine the relationship between near-roadway exposures to air pollutants and respiratory outcomes in a cohort of asthmatic children living near major roadways. The study enrolled 139 asthmatic children in Detroit, MI, aged 6-14, based on the proximity of their home to roadways having different amounts of diesel traffic. The epidemiological study was designed to contrast the health of children living within close proximity (150 m) to major roads (AADT > 90,000) to those living at least 500 m from such roads and at least 300 m from medium-sized roads (AADT > 25,000). While PM was an indicator of diesel exhaust emissions, CO concentrations had stronger correlation to traffic volume. This is an abstract of a paper presented at the 106th AWMA Annual Conference and Exhibition (Chicago, IL 6/25-28/2013).
