Title: Characterization and control of organic compounds emitted from air pollution sources.

Principal Investigator / Author(s): Schaur, Cass, Kleeman

Contractor: California Institute of Technology

Contract Number: 93-329

Research Program Area: Emissions Monitoring & Control

Topic Areas: Stationary Sources


A dilution source sampling system is used to quantify the air pollutant emissions from major urban air pollution sources. The emissions from catalyst-equipped gasoline-powered motor vehicles, noncatalyst gasoline-powered motor vehicles, diesel trucks, meat charbroiling, the cooking of vegetables with seed oils, fireplace combustion of softwood and hardwood, cigarette combustion and paint spray coating operations are characterized. Semi-volatile and particle-phase organic compounds in the diluted source emissions are collected simultaneously by both a traditional filter / PUF (polyurethane foam) sampling train and by an advanced organic compound-based denuder / filter / PUF sampling train to provide information on the gas / particle phase distribution of the semi-volatile organic compounds. Emission rates of hundreds of organic compounds, spanning carbon numbers from C1 to C29 are determined by gas chromatography / mass spectrometry and gas chromatography with flame ionization detection. Fine particle mass emission rates and fine particle elemental chemical composition are measured as well.
