Ozone Formation in Photochemical Oxidation of Organic Substances

In photochemical experiments conducted in sunlight and in concentrations of 3-methylheptane and nitrogen oxides approximating those known to occur during smog periods, it was found that ozone formation is proportional to the production of the hydrocarbon and nitrogen oxide concentrations. Present control measures are directed mainly toward reduction of hydrocarbon, while nitrogen oxides from high temperature combustion sources continue to increase. Since the reduction of hydrocarbon emission will only be partial, it is essential to study the other component of the smog-forming system, nitrogen oxides, and to institute engineering research necessary for the drastic reduction of nitrogen oxides released by combustion processes. 9 references, 4 figures, 1 table.
