Advancing the chemical characterization of carbonaceous aerosols for improving sourcereceptor modeling Michael D. Hays Photo image area measures 2 ” H x 6.93 ” W and can be masked by a collage strip of one, two or three images. The photo image area is located 3.19 ” from left and 3.81 ” from top of page. Each image used in collage should be reduced or cropped to a maximum of 2 ” high, stroked with a 1.5 pt white frame and positioned edge-to-edge with accompanying images. Office of Research and Development National Risk Management Research Laboratory June 21, 2007Characterizing carbonaceous aerosol • both organic and elemental carbon components in aerosols are poorly understood • develop health effects mechanisms (and apportion endpoints) • atmospheric reactions and processing • direct and indirect climatic effects of aerosols • improved exposure estimates • dispersion modeling 1 General discussion focus • analytical chemistry and source emissions aerosols • chemical mass balance (CMB) modeling • case examples – two-dimensional gas chromatography-mass spectrometry (2D GC-MS) for the identification and quantification of N-bearing molecules in biomass burning aerosols – GC with atomic emissions detection (AED) for organosulfur constituents in residential boiler effluents – high resolution-transmission electron microscopy (HR-TEM) for soot nanostructure determination – X-ray photoelectron spectroscopy (XPS) for determining aerosol surface chemistry and carbon chemical state 2 2D-GC-MS applied to aerosols TE-2D-GC/MS syste
