Abstract The Southeastern Center for Air Pollution and Epidemiology (SCAPE) is an EPA-funded Clean Air Research Center between the Rollins School of Public Health at Emory University and the schools of Civil and Environmental Engineering and Earth and Atmospheric Sciences at the Georgia Institute of Technology. SCAPE examines air quality and its health effects through a measurement campaign spanning urban and near-road sites in Atlanta, GA, Birmingham, Al and East St. Louis, IL, as well as rural background sites in Yorkville, GA and Centreville, AL.
Measurements were made on a continuous or semi-continuous basis of particle phase water soluble organic carbon (WSOC), brown carbon (BrnC), black carbon (BC), elemental carbon (EC), organic carbon (OC), ozone, NO, NO2, and PM2.5 mass. Measurements also included 23 hour filter based samples of soluble anions and cations, water soluble metals, elemental carbon, organic carbon, water and methanol soluble brown carbon, and oxidative potential. These measurements were made with pairs of instruments, in which one set of instruments was permanently located at a fixed urban background site in Atlanta, GA while the other set was installed in a trailer which was moved monthly between the other sites.
Measurements were made from May 2011 to September 2013 at seven different sites, rotating on a monthly basis. Results from the measurement phase of this study show regional, seasonal and diurnal trends in measured species as well as direct comparisons between the base site in Atlanta, Georgia and the other locations. These measurements will be used in epidemiological modeling as part of SCAPE to assess the health risks presented by exposure to air pollution mixtures.
