Characterization of Particulate Emissions: Size Fractionation and Chemical Speciation
Abstract
This study developed and validated innovative techniques for characterizing the amount and composition of PM10, PM2.5, and smaller particles for four major classes of DoD emission sources: aircraft ground support vehicles, rocket motors, aircraft, and sandblasting operations. The techniques include the coupling of dilution samplers with advanced measurement techniques for composition and size that provide detailed analyses sufficient to complete a material balance. The size-classified analyses include measurement made with the cascade impactor and aerosol time-of-flight mass spectrometer (ATOFMS). A photoelectric aerosol sensor (PAS) was being evaluated for use in rapidly evaluating field emissions of particle-bound polycyclic aromatic hydrocarbons (PAH). In addition, a photoacoustic spectrometer was investigated for use in measuring soot particle concentrations. The objective was to calibrate and enhance these instruments for DOD use. To this end, the devices are being demonstrated at DoD facilities, and the methodologies developed will be transferred to personnel responsible for monitoring emissions at DoD facilities
