Practical methods of reducing airborne contaminants in interior spaces.
Prediction of airborne concentrations of enviornmentally important contaminants is supported by field test data on tobacco smoke. The analysis discussed herein is completely general in nature, and the contaminants can be gases, vapors, liquid droplets, and solid particulates, including microorganisms and pollens. Several engineering controls can be applied to practical environnmental systems to reduce and control undesirable contaminants in normally occupied structures. The use of the method is an important research tool to more accurately quantify airborne contaminant levels in enviornmental medicine experiments with animals or human subjects. It is difficult and expensive to control inside environmental contaminant levels at values less than 20% to 25% of those occurring outside. The same is true for internally generated contaminants.
