Bioaerosols: Composition, Meteorological Impact, and Transport.

Affek et al. [[13]] also proved that both the type of biofilter bed and the number of microorganisms in the bed affected the final bioaerosol emission only for biofilters that treated waste gases with low microbial concentrations. The characterization and the main properties of biogenic airborne particles (or bioaerosols) comprising both living and dead microorganisms (such as bacteria, fungi, viruses, pollen, and microbial fragments) are currently of increasing interest in the scientific community. No correlation between the number of microorganisms and the respiratory activity in the biofilter beds was determined, while biofilters were seen to reduce or increase bioaerosol emissions from industrial plants, depending on the microbial content in the waste gases. In the scientific community devoted to bioaerosol characterization, the study of pathogenic species identified in aerosol samples is a topic of increasing interest. [Extracted from the article]
