Exposure estimates based on monitoring carbon monoxide in microenvironments are compared to exposure estimates based on personal monitoring with individual, portable monitors. Methods of calculation are reviewed and discussed, and results of calculations are presented. These 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 forty 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 data bases are not valid at this time.
