Abstract
An experimental design was developed utilizing five time periods from 0.5 to 7 hours with two nitrogen dioxide concentrations at each time period. Concentrations were chosen that would produce threshold and severe injury at these time periods. From these data for each plant species, an equation was developed utilizing concentration as the dependent variable, and both foliar injury and time as independent variables. The model allows for the development of a three-dimensional response surface within the limits of the times and concentrations used. The model should be of practical importance in predicting the concentration of nitrogen dioxide that will produce a given amount of injury to a specific crop during a single 12-hour day. Research to date suggests the model may be used for other pollutants and for other plant species that show injury following exposure to high ambient nitrogen dioxide concentrations.
