Smith, W., A. Williamson, AND editors. PROCEEDINGS: ADVANCES IN PARTICLE SAMPLING AND MEASUREMENT (DAYTONA BEACH, FL, OCTOBER 1981). U.S. Environmental Protection Agency, Washington, D.C., EPA/600/9-89/004.
Description:
The proceedings consist of reports of research on equipment and techniques for sampling and characterizing particulate emissions from industrial sources (e.g., nickel smelters and a power plant burning low-sulfur coal) and other aerosols (e.g., uranium oxide in high-energy environments, the launch exhaust of the NASA shuttle). Equipment included samplers designed for: collection of particles in the inhalable size range; collection of samples for wave-dispersive x-ray fluorescence; condensation and collection of vapors by dilution; and isokinetic sampling by gas recirculation. Other equipment included piezoelectric microbalances for monitoring mass emissions, a velocimeter for measuring aerodynamic particle sizes, a remote passive opacity meter, and an optical particle counter using coherent detection of phase-shifted light. Techniques included methods for impactor data reduction and prediction of sampler collection efficiency, and comparisons of methods: the EPA source assessment sampling system vs a dilution tunnel for collecting combustion emissions containing organic matter, non-intrusive optical probes vs extractive probes for measuring soot from a swirl-stabilized combustor, plume opacity vs mass concentration, and particle-sizing methods for measuring collection efficiency of fabric filters.
