The Steubenville Comprehensive Air Monitoring Program (SCAMP): concentrations and solubilities of PM2.5 trace elements and their implications for source apportionment and health research
- CONSOL Energy Inc. Research & Development, South Park, PA (United States)
The elemental compositions of the water-soluble and acid-digestible fractions of 24-hr integrated fine particulate matter (PM2.5) samples collected in Steubenville, OH, from 2000 to 2002 were determined using dynamic reaction cell inductively coupled plasma-mass spectrometry. The water-soluble elemental compositions of PM2.5 samples collected at four satellite monitoring sites in the surrounding region were also determined. Fe was the most abundant but least water soluble of the elements determined at the Steubenville site. Fe solubility and its correlations with SO{sub 4}{sup 2-} and temperature varied by season. Higher ambient concentrations were observed at Steubenville than at each of the four satellite sites for 10 of the 18 elements (Al, As, Ca, Cd, Fe, Mg, Mn, Na, Pb, and Zn) determined in the water-soluble PM2.5 fraction. Concentrations of Fe, Mn, and Zn at Steubenville were substantially higher than concentrations reported recently for larger U.S. cities. An (NH{sub 4}){sub 2}SO{sub 4}-dominated source, likely representing secondary PM2.5 from coal-fired plants to the west and southwest of Steubenville, accounted for 42% of the PM2.5 mass, and two sources likely dominated by emissions from motor vehicles and from iron and steel facilities in the immediate Steubenville vicinity accounted for 20% and 10%, respectively. Other sources included a primary coal combustion source (3%). Results suggest the importance of very different regional and local source mechanisms in contributing to PM2.5 mass at Steubenville and reinforce the need for further research to elucidate whether metals such as Fe, Mn, and Zn play a role in the PM2.5 health effects observed previously there. 76 refs., 8 figs., 6 tabs.
