Research Reports

Research Report 202 describes a study led by Dr. Stuart Batterman at the University of Michigan, Ann Arbor and colleagues. The investigators evaluated the ability to predict traffic-related air pollution using a variety of methods and models, including a line source air pollution dispersion model and sophisticated spatiotemporal Bayesian data fusion methods.

Research Report 200 describes the first-phase results of a study examining any association between exposure to low levels of air pollution — both PM_2.5 and O₃ — and all-cause mortality in a population of 61 million Medicare enrollees residing in the continental United States. The report also presents the detailed Commentary on the study by HEI’s Low-Exposure Epidemiology Studies Review Panel.

Research Report 197 describes a study led by Dr. Nga Ng to characterize and compare the oxidative properties of ambient particulate matter and laboratory-generated secondary organic aerosols in toxicologic assays.

Research Report 196, Developing Multipollutant Exposure Indicators of Traffic Pollution: The Dorm Room Inhalation to Vehicle Emissions (DRIVE) Study, describes a study by Dr. Jeremy A. Sarnat that evaluated single- and multipollutant metrics of exposure to traffic-related air pollutants near and farther away from a major highway in Atlanta, as well as biological markers in a panel of students.
