Willis, R. D. WORKSHOP ON UNMIX AND PMF AS APPLIED TO PM 2.5. Presented at Workshop on UNMIX and PMF as Applied to PM 2.5, Research Triangle Park, NC, February 14-16, 2000.
Impact/Purpose:
To use the tools of x-ray fluorescence (XRF), ion chromatography (IC), scanning electron microscopy (SEM), thermal optical (organic and elemental carbon -- OC & EC), and radiocarbon analysis combined with various receptor models to determine the contributions of sources to PM as measured in outdoor (ambient) environments or particular microenvironments involving human exposure issues.
Description:
This report is the proceedings of a workshop convened to evaluate two new air quality receptor models, Positive Matrix Factorization (PMF) and UNMIX. The workshop was held in Research Triangle Park, NC, during February 14 - 16, 2000 and was sponsored jointly by EPA's Office of Research and Development (ORD) and Office of Air Quality Planning and Standards (OAQPS). The workshop evaluation of PMF and UNMDC was accomplished by examining the results of applying both models to two ambient PM2.5 data sets, one real and one synthetically generated. Both data sets were supplied in advance to a proponent of each model (UNMIX: Dr. Ron Henry, University of Southern California; PMF: Dr. Phil Hopke, Clarkson University). Each brought to the workshop the results of independently applying their model to both data sets. The report briefly summarizes the technical exchange and major conclusions reached during the workshop.
The U.S. Environmental Protection Agency through its Office of Research and Development funded and managed the research described here under Contract 68-D5-0049 to ManTech Environmental Technology, Inc. It has been subjected to the Agency's peer and administrative review and has been approved for publication as an EPA document.
