Exposure measurement error in air pollution health effect studies: a pooled analysis of personal exposure validation studies in 17 communities across the United States.
Despite demonstrated adverse health effects of air pollution, the impact of exposure measurement error on these associations remains unexplored, especially for NO2 and PM2.5 components. We compiled daily personal measurements of PM2.5, NO2, and PM2.5 components – including Al, Cd, Fe, K, Ni, Pb, S,...

We compiled daily personal measurements of PM2.5, NO2, and PM2.5 components – including Al, Cd, Fe, K, Ni, Pb, S, and Si – from previous studies as true exposure indicators. These were compared against ambient concentrations from the nearest monitors. We used Spearman correlation to examine relationships between monthly averages of personal exposures and ambient concentrations. Calibration coefficients were derived using linear mixed models to quantify measurement errors. Results showed strong correlations between monthly personal exposures and ambient concentrations for PM2.5, NO2, Cd, Ni, S, and Si across the US. Calibration coefficients for personal PM2.5 and NO2 were 0.46 (95% CI: 0.13, 0.78) and 0.97 (0.35, 1.59), respectively. Significant coefficients were also found for S (0.48; 95% CI: 0.27, 0.68), Cd (0.47; 0.17, 0.76), and Ni (0.17; 0.02, 0.32). Point estimates for calibration coefficients were all below one, indicating that using the nearest monitors as exposure surrogates would attenuate associations with health risks. The measurement error in component-wise analysis highlights the need for incorporating these calibration coefficients into future studies to adjust for such errors adequately. pubtype: Academic Journal doctype: pictorial research tables/charts Journal Article ougenre: Article language: English refInfo: holdings: @attributes: islocal: N |
