Small airborne particles ranging from 0.02-100 µm in size having biological origin are referred as bioaerosols. These include fungi, bacteria, pollens, spores, algae, protozoa and viruses, lichen and mycotoxins. 1 Derived from plants and animals, these living or dead micro particles can be transported by air to a larger distance affecting air quality. 2 We get infected through inhalation. One interesting example of transmission through air inhalation is SARS COV-2 virus. [3][4][5] Sometimes their contributions reach upto 50% in the total aerosols. 6 Since, these particles are airborne, humans inhale these during breathing. 7 Residential and occupational buildings especially with insulation having poor ventilation are reported having human health effects. Sick building syndrome is more associated with health effects of bioaerosols. However, due to complex nature of human system, health risks due to the effect of the bioaerosols for bronchitis diseases, infections, allergies, and other illnesses are not properly understood. Impact of bioaerosols on crop has also been reported due to emerging fungal diseases having a possible threat to food security. 8
