Ozone is formed in and downwind of urban areas from urban emissions of NO x and volatile organic compounds (VOCs) in the presence of sunlight. The main sources of VOCs in polluted air are motor vehicles, industrial solvents, processes in the petroleum and chemical industries, and vegetation. The main NO x sources are stationary‐source fuel combustion (mainly electric utilities) and motor vehicles. Recent studies have demonstrated that VOC emissions from motor vehicles have been seriously underestimated, and this may well explain why ambient O 3 has not responded well to control efforts. This review presents an overview of the sources, formation, and potential abatement strategies for O 3 pollution in the troposphere, with particular emphasis on the mobile source contribution to O 3 formation.
