Pollution in the atmosphere over metropolitan areas may have a considerable effect on the viability of airborne micro-organisms. The concentration, chemical identity, and number of pollutants vary with the fuel and industrial economy as well as with the population of metropolitan areas. It is important in assessing the action of airborne micro-organisms to know which of the many air pollution components may interact with these organisms. Also, the critical pollution concentrations above which such organisms may not remain viable must be known and be relatable to population level and economy. This report contains extensive tabulations of measured concentration of all pollutants found in metropolitan atmospheres in connection with air pollution investigations. The second phase of the study involved selection of a complete pollution simulant formulation representative of the average maximum concentrations of all known atmospheric pollution components. A discussion follows of the methodology, techniques, and equipment for preparation, sampling, and assay of the proposed test formulation to be created for use in connection with a static test chamber held at a slight negative pressure.
