Air Quality Data Analysis System for Interrelating Effects, Standards, and Needed Source Reductions: Part 7. An O3-SO2 Leaf Injury Mathematical Model

摘要

Leaf injury data from acute and chronic exposure studies of Dare soybean were regressed against the logarithms of exposure time and O3 and SO2 concentrations to develop a new two-pollutant leaf injury model (which explains 88% of the variance) and to calculate the parameters of best fit for this new model and a previously developed one-pollutant model. Using the calculated parameters, the percentage of leaf surface injured over a growing season by O3, SO2, or both simultaneously was estimated for an ambient air sampling site located 2 miles from a coal-burning power plant.
