The formation of ozone under simulated conditions of pollutant transport was studied in a group of four 27-cubic-meter outdoor smog chambers. The chambers were constructed of 5 mil FEP Teflon on aluminum frames. The initial charges in the smog chambers were irradiated for three days by natural sunlight. Simulation of transport was accomplished by progressively diluting the contents of the chambers with clean air. The analogy between the chemical behavior of chamber simulations and nonurban high-ozone (i.e., 0.08 ppm) systems in the field was good. On the second and third days, the initial charges in the chambers generated ozone concentrations greater than the National Ambient Air Quality Standard for photochemical oxidant (0.08 ppm). The initial charge of nonmethane hydrocarbon (NMHC) ranged from 1.0 to 10.0 ppmC; nitrogen oxides (NOx) ranged from 0.100 to 1.000 ppm. Therefore, initial ratos of NMHC/NOx varied from 7 to 20. On the second and third days in the chambers, concentrations of NOx ranged from 0.001 to 0.053 ppm; NMHC ranged from 0.33 to 3.78 ppmC. The resulting NMHC/NOx ratios varied from 16 to 610. This report was submitted in fulfillment of EPA contract 68-02-1296 (43U-994, RTI Contract Number) by the Research Triangle Institute under the sponsorship of the Environmental Protection Agency.
