Project Update (573kb .pdf)

map of projectTo improve our current understanding of the organic compounds associated with fine particle (PM2.5) pollution, this study uses molecular-level technology to match the chemical "fingerprints" of collected PM2.5 samples to primary and secondary emission sources. The project includes:

  • Detailed chemical analysis of organic molecular markers of PM2.5 samples from New York City;
  • Measurement of organic molecular markers in PM2.5 from upwind sources, enabling a comparison of urban and regional (background) sites;
  • Updating of emission profiles of light-duty gasoline and diesel vehicles through measuring organic markers;
  • Determination of organic emission profiles in seed oils.

The study is expected to identify monthly and seasonal concentrations of organic PM2.5 compounds, offering more detailed chemical information that will benefit other PM2.5 source-apportionment and health-effects research.
