Abstract |
This project was conducted to provide a national exposure, in terms of person hours, to non-reactive mobile source pollutants. The basis for the estimate was the EPA 'NAAOS Exposure Model' (NEM) as applied to carbon monoxide, supplemented by four mobile source microenvironments: parking garages, street canyons, on-expressways, and roadway tunnels. From previous studies, both published and unpublished, CO concentration distributions and national population estimates, by hour of the day, for each of these mobile source microenvironments were developed. That information was combined to determine national exposure in the microenvironments. By using the mobile source CO emission factor, exposure to mobile source pollutants based on a pollutant emission rate of one gram per minute was determined for each of the microenvironments and the environments covered by the NEM. The methodology for using this information to determine exposure to any mobile source pollutant, regulated or unregulated was explained. |
