The regional impacts of ozone on corn, wheat, soybean, and peanut crops are estimated by using dose-response functions to relate ambient maximum 7 h/d seasonal ozone concentrations to crop productivity data. Linear dose-response functions were developed from open-top field chamber studies. It was assumed that the limited number of cultivars and growing conditions available for the analysis were representative of major agricultural regions. Hourly ozone data were selected to represent rural concentrations and used to calculate maximum 7-h/d average values. Seasonal ozone averages for counties were extrapolated from approximately 300 monitoring sites. Results must be interpreted with knowledge of these assumptions and sources of uncertainty. Impacts are calculated for county units for the conterminous United States with maps showing patterns and tables summarizing the potential magnitude of ozone effects on selected crop yields. The assessment estimates that approximately three billion dollars of productivity could be gained if current maximum 7 hour per day ozone levels were reduced from present levels to below 25 parts per billion. Dollar values are based on 1978 crop prices, without accounting for price effects, to provide an overall estimate of the impact. Of the estimated economic impact, soybean represents 64%, corn 17%, wheat 12%, and peanuts 7%.
