Comparison of Microenvironment Monitoring with Personal Monitoring in Estimating Population Exposure to Carbon Monoxide
This Note compares exposure estimates based on monitoring carbon monoxide in microenvironments to exposure estimates based on personal monitoring. The author reviews methods of estimation, and presents results of estimation. The data indicate that population exposure estimates based on data from the Washington Microenvironment Study, combined with people's activity data from the Washington Urban Scale Study, are about 40 percent higher than estimates based on personal monitoring data from the Urban Scale Study. The former set of exposure estimates is found to be a good predictor of the latter. Nevertheless, generalizations of these findings to other databases might not be valid.
