Short summary
Exposures to bioaerosols depend on their type, particle size, and concentration. While typically found in coarse particles (2.5–10 microns), pollens, fungal spores, and bacterial endotoxins decrease to less than 2.5 microns and simultaneously increase in concentration during rain events. These observations contrast the assumption that rain washes bioaerosols from the air and reduces allergen levels. Instead, population exposures to bioaerosols are expected to be enhanced during rain events.
