Chemical Composition of Fine Organic Particles from Urban and Regional Background Locations in New York State (7616)

Principal Investigator(s):

Monica Mazurek


map of New York City regionTo 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:

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.
