The kind and number of airborne microbes vary tremendously in different environments and dependent upon the activity in the environment and upon the amount of dust stirred up. The most significant environmental factors influencing viability of microbes are temperature, relative humidity and wind velocity. Other factors influencing their survival are oxygen, air ions, solar irradiance and open air factors. Among the microbes present in the atmosphere, bacteria are highest in number. In Outdoor air. .
