Fine-Scale Modeling of Individual Exposures to Ambient PM_2.5, EC, NO_x, CO for the Coronary Artery Disease and Environmental Exposure (CADEE) Study.

ABSTRACT: Air pollution epidemiological studies often use outdoor concentrations from central-site monitors as exposure surrogates, which can induce measurement error. The goal of this study was to improve exposure assessments of ambient fine particulate matter (PM_2.5), elemental carbon (EC), nitrogen oxides (NO_x), and carbon monoxide (CO) for a repeated measurements study with 15 individuals with coronary artery disease in central North Carolina called the Coronary Artery Disease and Environmental Exposure (CADEE) Study. We developed a fine-scale exposure modeling approach to determine five tiers of individual-level exposure metrics for PM_2.5, EC, NO_x, CO using outdoor concentrations, on-road vehicle emissions, weather, home building characteristics, time
