ABSTRACT
Bioaerosols can contain living organisms, including bacteria, viruses, fungi, actinomycetes, arthropods, and protozoa. They can also contain microbial products such as endotoxin, microbial enzymes, β-1(3)-glucans, and mycotoxins (American Conference of Governmental Industrial Hygienists [ACGIH] 1999). Many of the bioaerosols are ubiquitous in both indoor and outdoor environments. The sources can be soil, plants, organic matter, animals, and humans.
