The report assesses laboratory and field studies conducted over the past several years and discusses how the findings affect current and projected programs to control oxidants. Both maximum concentrations and the frequency of violations of the air quality standards for oxidants have decreased in some urban areas as a result of recently initiated controls. However, long thought to be primarily an urban problem, oxidant levels well in excess of the standard have been observed in broad areas in the eastern third of the U.S. Although naturally occuring sources such as vegetation and the stratosphere do contribute to these high levels, man's activity is their predominant cause. Instances are noted in which oxidants and their precursor compounds have been carried up to 50 miles, and probably farther. More extensive control of oxidant-producing compounds will be required in rural areas while emphasis continues to be placed on control in the cities.
