The impact-effect mathematical model was developed previously to predict biological response as a function of air pollutant impact (exposure duration multiplied by pollutant concentration raised on an exponent). The purpose of this paper is plot and regress example effects on man, animals, and plants (a wide range of life forms) as a function of air pollutant impact to determine how well the plotted data fit this model and to determine, especially, how well both acute and chronic exposure data fit the model. The three examples of air pollutant effects plotted and regressed are: for man, lung function decrease after exposure to ozone (O3); for animals, mice mortality after exposure to nitrogen dioxide (NO2); and for plants, leaf injury after exposure to O3. The resultant impact-effect equations explain 95 percent of the variance for the lung function data, 92 percent for leaf injury, and 73 percent for mice mortality.
