The urgency for an interim bacterial aerosol detection device is reflected in the need for an adequate means of defenss against biological warfare attack. A preliminary survey was ordered to evaluate several existing bacterial aerosol sampling devices in regard to their ability to consistently and reliably detect the presence of an artificially induced bacterial aerosol in the atmosphere. Tne candidate sampling devices evaluated in this study included several slit samplers, millipore filter samplers, all-glass impingers, and multistage Andersen Samplers. The results of this study indicated that, of the different sampling devices evaluated, the 6-stage Andersen Sampler and the 4-stage modified Andersen Sampler were superior in terms of consistency and reliability to detect the presence of the artificially induced bacterial aerosol in the atmosphere.
