MCDOW, S. R., J. TURLINGTON, D. A. OLSON, L. STOCKBURGER, R. W. WILLIAMS, AND A. F. VETTE. ORGANIC MOLECULAR MARKER ANALYSIS OF LOW VOLUME RESIDENTIAL SAMPLES FOR SOURCE APPORTIONMENT IN THE DETROIT EXPOSURE AND AEROSOL RESEARCH STUDY. Presented at International Aerosol Conference (AAAR/ISAM), St. Paul, MN, September 10 - 15, 2006.
Impact/Purpose:
The goal of this task is to develop methods and models to reduce the uncertainty in quantifying the air pollutant source impacts on residential indoor/outdoor and personal samples. A combination of high sensitivity organic and analytical methods, and models will be developed and evaluated to reduce the uncertainty in source apportionment:
(1) Organic analysis methods for low flow samples
(2) Multivariate models for residential indoor and outdoor, and personal samples
(3) Innovative low cost coarse fraction sampling methods.
In addition, this task contributes to two additional tasks that have research focused on reducing the uncertainty in source apportionment: Identifying Local and Regional Sources (21120), and NAAQS Implementation (21179).
Description:
This abstract describes a poster on results for organic speciation analysis for Detroit Exposure and Aerosol Research Study (DEARS) 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. Analytical methods suitable for analysis of low volume and high volume samples by gas chromatography/mass spectrometry are reported. Preliminary results and concentration trends for high volume samples at the DEARS central site are presented.
