The basic program objectives are to develop, to design, and to fabricate a complete aerosol assessment system. These were reviewed in terms of the capability of the instrumentation for the measurement of the mass concentration of active agent, concentration of degraded agent and inert materials, describing particle-size parameters for active agents, shape factor for solid particles, and bioeffectiveness. Sampling techniques were reviewed e. g., filtration, inertial collection, scrubbing and absorbing, electrostatic, thermal percipitator, and sedimentation, interpreted in terms of their applicability to the system. Special attention was given to proposed instruments for particle-size assessment. Several analytical methods for mass assessment are discussed including wet-chemical techniques and instrumental methods. Results of experiments in a 1 m3 test chamber are presented and discussed in such terms as floor sampling, an automatic particle counter, a beta absorption mass meter, a porous electrode collector, particle decay analysis, a viewing microscope, mean decay of saccharin aerosols, sample size, location and time, and representative sampling.
