Early air pollution research focused on determining the identity of the concentration distributions for a variety of pollutants and locations and the relationships between attributes of the data, e.g., mean values, maximum levels and averaging times, from an empirical standpoint. this report attempts to identify the nature of the frequency distributions for both reactive and inert pollutants, for both point and area sources, and to some extent for different types of atmospheric conditions using a substantially non-empirical approach. As an illustration of the applicability of these results, a predictive model and a monitoring scheme are proposed based upon knowledge development by studying the frequency distributions.
