Glenn, G. AND D. S. Shadwick. ANALYSIS OF CARBON MONOXIDE EXPOSURE FOR FOURTEEN CITIES USING HAPEM-MS3 (FINAL TECHNICAL REPORT). U.S. Environmental Protection Agency, Washington, DC, EPA/600/R-99/096 (NTIS PB2000-101197), 1999.
Description:
This report describes results and findings of applying the Hazardous Air Pollutant Exposure Model (HAPEM) for mobile sources, Version 3. This version is formally known as HAPEM-MS3. The application is to fourteen urban areas for calendar year 1990. The urban areas modeled include Baltimore, Boston, Chicago, Denver, Houston, Los Angeles, Minneapolis, New York City, Philadelphia, Phoenix, San Francisco, Spokane, St. Louis, and Washington DC.
The report contains a description of the HAPEM-MS3 model, model results and a discussion of their implications, an uncertainty assessment, and a description of quality control measures undertaken during conduct of the study. Appendices contain detailed tables of model results of all 14 areas and a map of each area. Principle results are urban-area specific tables containing human exposure estimates to ambient carbon monoxide sources disaggregated by demographic groups, calendar quarter of the year, and by county within an urban area. Other tables are presented that focus on summary statistics for )pulation exposure estimates by hour, air district, and microenvironment where the exposure people are located. Percentile and fractile estimates of population exposure are also presented for selected population cohorts.
