Abstract
The observed deposition pattern from a field spray ofBacillus subtilus var.niger spores is compared with that of a computer simulated bioaerosol particle dispersion model. Using the same meteorological conditions as the field spray, the model produced a bioaerosol deposition pattern estimated to be reasonably similar (R 2=0.66) to the observed field pattern. Reasons for the differences between the deposition patterns are discussed. The comparison indicates that viable airborne particle deposition models may, with future testing, be useful tools for predicting near source aerial microbial dispersal and deposition.
