X-ray fluorescence (XRF) and X-ray absorption fine structure (XAFS) spectroscopy, supplemented by other techniques, have been used to investigate the concentrations, solubility, and chemical speciation of sulfur and other key elements (As, Fe, Se, Zn) in ambient PM2.5 samples collected in Lexington, KY, a location in the eastern central USA that is surrounded by many coal-burning electricity generating stations. The goals of the investigation were (i) to identify how these elements occur in PM2.5, with emphasis on S, Fe and Zn because they have been implicated (albeit weakly) in epidemiological studies as agents in PM2.5 that are potentially harmful to humans, and (ii) to establish the significance of emissions from coal-fired power plants contributing to ambient PM2.5 in Lexington.
