What Are Bioaerosols?
Bioaerosols consist of airborne particles that contain living organisms, such as bacteria, fungi and viruses or parts of living organisms, such as plant pollen, spores and endotoxins from bacterial cells or mycotoxins from fungi. As such, they are found in the natural environment. The airborne particles that make up bioaerosols are extremely small and are not visible to the naked eye as they range in size from around 0.02 to 100 micrometres in diameter. The size, density and shape of a bioaerosol will affect its behaviour, survivability and ultimately its dispersion in the atmosphere. The behaviour and the ability for the bioaerosol to survive is dependent on the shape, density and size of the bioaerosols.
