Figure 2 illustrates aerodynamic size distribution of airborne bacteria in the pig building and the results are as follows: stage 1 (19%), stage 2 (23%), stage 3 (22%), stage 4 (20%), stage 5 (10%), and stage 6 (6%) for gestation/farrowing room; stage 1 (18%), stage 2 (22%), stage 3 (20%), stage 4 (19%), stage 5 (10%), and stage 6 (11%) for nursery room; and stage 1 (20%), stage 2 (24%), stage 3 (19%), stage 4 (16%), stage 5 (13%), and stage 6 (8%) for growing/fattening room, respectively.
In addition to chemical composition, it is also important to understand particles' size because its potential action in the respiratory tract is related to its aerodynamic size. Inhalable particles (< [PM.sub.10]) can enter the upper respiratory tract, where they can be retained.

The resulting simulant material has a spherical morphology and is ~1 to 10 [micro]m in aerodynamic size; the size of particle can be adjusted depending on the application.
