Abstract : This project responded to the need to identify and characterize emissions of trace air toxic compounds, especially persistent organic pollutants, from operations and activities at Department of Defense (DoD) facilities. The project had three main objectives: (1) development of field-portable CEM instrument (miniature sensors and arrays) capable of detecting and characterizing trace air toxic compounds rapidly in near-real-time; (2) integration of pollutant-data collection into spatial and temporal emission profile models of pollutants and correlating these with specific DoD activities; (3) development of improved emission factors for the targeted pollutants released during various activities. The emission factors and the quantifiable estimates of their uncertainty were to be incorporated into a structured, verifiable, user-friendly model. Project deliverables were to be new toxic gas CEM instrument, an emissions model for mobile and stationary emissions sources, and a software tool for calculating EPA-approved emission factors. The first of the objectives was accomplished. A significant portion of the second objective was accomplished by completing a large portion of the field testing in a special-purpose Diesel Engine Test Facility (DETF) in Argonne's Center for Transportation Research. Testing at the DETF greatly reduced project expenses and allowed the project to advance despite a funding reduction during the second year. Using the DETF, a library of chemical composition signatures was developed for acetaldehyde, acrolein, benzene, and 1,3-butadiene in air and in diesel exhaust at several different concentrations and in a wide range of combinations. The project was discontinued by SERDP before the second objective was finished and before the third objective (emission model and emissions factors) could begin.
