In 1999, CONSOL Energy Inc. Research & Development (CONSOL R&D), in cooperation with research partners and funding agencies, launched the Steubenville Comprehensive Air Monitoring Program (SCAMP) to clarify uncertainties regarding fine particulate matter (PM2.5) concentration, composition, and exposure. The study was conducted in Steubenville, Ohio, a small but heavily industrialized city located in the Upper Ohio River Valley that historically has had elevated particulate matter (PM) concentrations and been a key location for PM health effects research. In addition to providing a much-needed current assessment of PM2.5 in Steubenville, which had been studied previously during the late 1970s and 1980s as part of the Harvard Six Cities Study, SCAMP helped to fulfill a number of PM2.5 research needs that remained after the U.S. Environmental Protection Agency (EPA) promulgated a new National Ambient Air Quality Standard (NAAQS) for PM2.5 in 1997. These included the need for better estimates of the relationship between ambient concentrations of PM2.5 and its components and actual human exposures to these species, the need to characterize the potential for confounding by gaseous pollutants in PM2.5 epidemiology studies, the need for better characterization of individual chemical components of PM2.5, and the need for data to develop State Implementation Plans (SIPs) in response to the PM2.5 NAAQS. / Supplementary Notes: Prepared in cooperation with Harvard School of Public Health, Boston, MA.
