Chemistry. Proceedings of a Conference on the State of the Art of Assessing Transportation-Related Air Quality Impacts, Washington, October 22-24, 1975.

This examination of the various methods now available to relate ambient oxidant to emissions, discusses briefly, the chemical and physical mechanisms by which emissions are dispersed in the atmosphere, get transported and react to form urban, suburban and nonurban oxidant. Four alternative methods for relating air quality to emissions are presented.
