ABSTRACT
In each cubic metre of air, there are hundreds or millions of cells belonging to airborne microorganisms, which comprise a significant portion of atmospheric aerosols. For effective environmental management and a thorough understanding of the effects of air pollution on human health, extensive monitoring of atmospheric bioaerosol concentrations is essential. This is due to the fact that bioaerosols may result in a variety of infectious illnesses as well as allergic and toxic responses. Bacterial aerosols are released into the atmosphere through a variety of sources, including soil, plants, and water as well as via animal, human, and industrial activity, all of which may happen in an urban setting. The harmful consequences of bioaerosols on the human respiratory system, from viral disorders to allergies and asthma, are especially well established. The purpose of this study was to establish the bacteriological air quality Laboratories at the University of Benin's Microbiology Department. By figuring out the quantities and make-up of the bacteria present in the indoor air, the Department of Microbiology at the University of Benin evaluated the microbial evaluation of the indoor air quality of its labs. By using settle plate techniques, which required exposing media-filled petri dishes to the air for 15 minutes, air samples were obtained from two distinct sites. For the purpose of counting the overall bacterial concentrations, nutrient agar was exposed.
