Abstract

Analyses of air pollution data indicate that air quality measurements tend to fit a general mathematical model having specific characteristics. These characteristics have been used to develop equations that may be employed to calculate the geometric mean, standard geometric deviation, maximum concentration, and various percentile concentrations of air pollutants. To illustrate the predictive, as well as the interpretive value of the model, parameters have been first calculated for one averaging time from actual data and then calculated for other averaging times by means of the model. Maximum concentrations with the model are compared with measured values for seven gaseous pollutants obtained during continuous sampling for up to 7 years in eight cities. The resulting information can be used in developing implementation plans and emission standards. All the equations needed for performing the calculations are listed.
