Traffic-related air pollutants, including carbon monoxide, nitrogen oxides, particulate matter less than 2.5 \u03bcm in diameter, and diesel exhaust emissions, have been associated with adverse human health effects, especially in areas near major roads. In addition to emissions from vehicles, ambient concentrations of air pollutants include contributions from stationary sources and background (or regional) sources. Although dispersion models have been widely used to evaluate air quality strategies and policies and can represent the spatial and temporal variation in environments near roads, the use of these models in health studies to estimate air pollutant exposures has been relatively limited. This paper summarizes the modeling system used to estimate exposures in the Near-Roadway Exposure and Urban Air Pollutant Study, an epidemiological study that examined 139 children with asthma or symptoms consistent with asthma, most of whom lived near major roads in Detroit, Michigan. Air pollutant concentrations were estimated with a hybrid modeling framework that included detailed inventories of mobile and stationary sources on local and regional scales; the RLINE, AERMOD, and CMAQ dispersion models; and monitored observations of pollutant concentrations. The temporal and spatial variability in emissions and exposures over the 2.5-year study period and at more than 300 home and school locations was characterized. The paper highlights issues with the development and understanding of the significance of traffic-related exposures through the use of dispersion models in urban-scale exposure assessments and epidemiology studies.<\/jats:p>","DOI":"10.3141\/2452-13","type":"journal-article","created":{"date-parts":[[2015,2,20]],"date-time":"2015-02-20T21:07:33Z","timestamp":1424466453000},"page":"105-113","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":33,"title":["Dispersion Modeling of Traffic-Related Air Pollutant Exposures and Health Effects among Children with Asthma in Detroit, Michigan"],"prefix":"10.1177","volume":"2452","author":[{"given":"Stuart","family":"Batterman","sequence":"first","affiliation":[{"name":"Environmental Health Sciences, University of Michigan, 1425 Washington Heights, Ann Arbor, MI 48109-2029."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Rajiv","family":"Ganguly","sequence":"additional","affiliation":[{"name":"Environmental Health Sciences, University of Michigan, 1425 Washington Heights, Ann Arbor, MI 48109-2029."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vlad","family":"Isakov","sequence":"additional","affiliation":[{"name":"National Exposure Research Laboratory, U.S. Environmental Protection Agency, 109 TW Alexander Drive, Research Triangle Park, NC 27711."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Janet","family":"Burke","sequence":"additional","affiliation":[{"name":"National Exposure Research Laboratory, U.S. Environmental Protection Agency, 109 TW Alexander Drive, Research Triangle Park, NC 27711."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Saravanan","family":"Arunachalam","sequence":"additional","affiliation":[{"name":"Institute for the Environment, University of North Carolina, 100 Europa Drive, Suite 490, Campus Box 1105, Chapel Hill, NC 27711."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michelle","family":"Snyder","sequence":"additional","affiliation":[{"name":"National Exposure Research Laboratory, U.S. Environmental Protection Agency, 109 TW Alexander Drive, Research Triangle Park, NC 27711."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Robins","sequence":"additional","affiliation":[{"name":"Environmental Health Sciences, University of Michigan, 1425 Washington Heights, Ann Arbor, MI 48109-2029."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Toby","family":"Lewis","sequence":"additional","affiliation":[{"name":"Department of Pediatrics, University of Michigan, 1500 East Medical Center Drive, Ann Arbor, MI 48109-5212."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2014,1,1]]},"reference":[{"key":"bibr1-2452-13","unstructured":"The Contribution of the Transport Sector to Total Emissions of the Main Air Pollutants in 2009 (EEA-32).
