Fine Particulate Matter Source Attribution for Southeast Texas Using 14C/13C Ratios



K R. Lemire, D T. Allen, George A. Klouda, C. W. Lewis


Radiocarbon analyses of fine particulate matter samples collected during the summer of 2000 in southeast Texas indicate that a substantial fraction of the aerosol carbon at an urban/suburban site (27-73%) and at a rural, forested site (45-78%) was modern carbon.Data from emission inventories and additional ambient measurements indicate that the most likely sources of this modern carbon are biomass burning fires and biogenic secondary organic aerosol.
