What is microbial air quality?
Microbial pollution involves hundreds of species of bacteria and fungi that grow indoors when sufficient moisture is available. Exposure to microbial contaminants is clinically associated with respiratory symptoms, allergies, asthma and immunological reactions.
What are the reasons to study microbial air quality?
The presence of bacteria and fungi in indoor air pose a serious problem from the point of view of health protection and environmental engineering. Precise determination of various groups of microorganisms in- doors is necessary both to estimate the health hazard and to create standards for indoor air quality control.
Why is indoor air quality important in schools?

What is causing bad air quality?
There are many factors that can lead to poor air quality, but the two most common are related to elevated concentrations of ground-level ozone or particulate matter. Sunshine, rain, higher temperatures, wind speed, air turbulence, and mixing depths all affect pollutant concentrations.
