Ratio of viable and nonviable bioaerosol
"Responsible evaluation of environmental conditions determines the ratios of viable and nonviable spores and the concentration of other airborne particulate material. The ratio of viable to nonviable airborne contamination tells the experienced indoor air quality professional considerable information relative to the dynamics of bioaersols within the environmental spaces. A change in the ratios may change the associated effect upon occupants and may be relevant to a variety of other influencing environmental factors."Viable / Nonviable Scientific testing. These techniques involve the scientific sampling of the environmental air. It is customarily advantageous to note the conditions of the environment when this air sampling is performed; example would be if doors are isolated and closed and if air conditioning or ventilation fans are operational at the time.
Viable tests determine the concentration of viable spores within the environmental atmosphere. The results of the analysis of these tests are usually reflected in Colony Forming Units per cubic Meter of air or CFU.
Nonviable and bulk particulate samples determine the type and concentration of all environmental airborne contaminants. The result of analysis of these samples is usually reflected by total particles per cubic meter of air.
