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

Abstract: 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% to 73%) and at a rural, forested site (44% to 77%) 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.

Although the research described in this article has been funded in part by the U.S. EPA through cooperative agreement R-82806201, interagency agreement DW13937923 and contract 68-D-00-206, it has not been subjected to the Agency's required peer and policy review and therefore does not necessarily reflect the views of the Agency and no official endorsement should be inferred.
