Determinants Of The Associations Between Ambient Concentrations And Personal Exposures To Ambient Pm2.5, No2, And O3 During Dears

In this analysis, ambient concentrations and personal exposures to PM2.5, O3, and NO2, air exchange rates, meteorological parameters, and questionnaire survey responses collected during the Detroit Exposure and Aerosol Research Study (DEARS) are used: 1) to evaluate different methods for estimating personal exposure of ambient origin for PM2.5, O3, and NO2; and 2) to characterize the impacts of exposure determinants on the Ea-Ca associations for PM2.5, O3 and NO2.

Impact/Purpose

Adequate accounting for the effects of exposure determinants on the associations between personal exposures and ambient concentrations will lead to a better understanding of these associations and of the uncertainties associated with using ambient concentrations as surrogates for personal exposures of ambient origin.
