Abstract
The (sup 14)C source apportionment technique for tracing environmental carbon has been applied to fine (<2.5 micrometer diameter) atmospheric particles collected in Albuquerque, NM and Raleigh, NC, during the winter of 1984 to 85. The work was part of the EPA's Integrated Air Cancer Project (IACP). The major objective of the study was to quantify the impact of wood-burning (living carbon source) and motor-vehicle ((sup 14)C = 0) emissions on these urban airsheds through (sub 14)C measurements. Additionally, (sup 14)C measurements were necessary for evaluation of the EPA's single-tracer multiple-linear regression model (MLR) for source apportionment. Good agreement was attained between (sup 12)C and MLR. Future work includes applying these two techniques to samples collected in Boise, ID.
