In every field of activity where organic material is being handled, emissions of dust, gases, odor as well as bioaerosols are bound to arise. For this reason, waste management facilities or else agricultural enterprises are potential emission sources of bioaerosols. The dispersion of bioaerosols from waste treatment facilities and their health impacts continue to be the subject of numerous discussions. This article addresses organizational and engineering measures for the mitigation of bioaerosol emissions. The required scale of emission reduction and the choice of microbiological parameters have to be assessed with respect to location and facility type.
