EVIDENCE OF SEED OILS IN FINE PARTICLES FROM THE NEW YORK METROPOLITAN AREA
MAZUREK, M. A., M. LI, S. R. MCDOW, AND C. BELISLE. EVIDENCE OF SEED OILS IN FINE PARTICLES FROM THE NEW YORK METROPOLITAN AREA. Presented at International Aerosol Conference (AAAR/ISAM), St. Paul, MN, September 10 - 15, 2006.
The goal of this task is to develop methods and models to reduce the uncertainty in quantifying local and regional air pollutant source impacts on ambient samples collected in speciated PM, air toxic, and semi-continuous measurement networks. A combination of high resolution sampling, organic and inorganic analytical methods, and models will be developed and evaluated to reduce the uncertainty in source apportionment:
(1) semi-continuous inorganic species sampling
(2) inorganic analysis
(3) organic analysis for medium flow samples
(4) multivariate receptor models for ambient samples
(5) regional and local models
In addition, this task contributes to two additional tasks that have research focused on reducing the uncertainty in source apportionment: Identify Sources of Human Exposure (21176), and NAAQS implementation (21179).
This abstract describes a poster on the contribution of seed oils used for cooking to organic particulate matter to be presented at the 2006 International Aerosol Conference sponsored by the American Association for Aerosol Research in St. Paul, Minnesota on September 10-15. Samples were collected in New York City as a part of the Speciation of Organics for Apportionment of PM-2.5 (SOAP) project between May of 2002 and May of 2003. Concentration patterns for individual long-chain aliphatic carboxylic acids are unlikely to be from plant or microbial sources, but are more likely due to the use of seed oils in cooking and indicative of cooking as a significant source of particulate organic matter in New York City.
