Monitoring of particulates in recirculated air.
The recirculation of industrial exhaust air: proceedings of a symposium, October 6-7, 1977, Cincinnati, Ohio. Cincinnati, OH: U.S. Department of Health, Education, and Welfare, Public Health Service, Centers for Disease Control, National Institute for Occupational Safety and Health, Contract 210-77-0056, 1977 Dec; :89-104
Various categories of particulate monitoring devices are identified and criteria for successfully monitoring particulates in recirculated exhaust air are given in a paper presented at a symposium held October 6-7, 1977 in Cincinnati, Ohio. Gaseous monitoring is also discussed. The five primary measurement domains are: 1) outside (ambient) air; 2) inplant air; 3) stack (stationary source) emission; 4) automotive exhaust (mobile source) emission; and 5) ventilation ducts. The measured parameters included concentration range of pollutant, condition of effluent, movement of monitored air, particle size distribution, chemical composition, instrument sensing method and instrument design. Each category of instruments is evaluated against these criteria as part of a selection process for identifying optimum instrumentation. Instrumentation includes light scattering devices, opacity monitors, optical tape samplers, electrical methods, condensation nuclei counters, piezoelectric mass monitors, and beta attenuation mass monitors. The advantages and limitations of the selected categories are also examined.
