Sulphur dioxide concentrations are declining in urban areas of most high income countries, but in many cities of low and middle income countries ambient concentrations continue to increase. Ozone and other photochemical oxidants Ozone and other photochemical oxidants are formed in air by the action of sunlight on mixtures of nitrogen oxides and VOCs. A complex series of photochemical reactions produce various oxidants, the most important being ozone and peroxyacetyl nitrate (PAN). Ozone is removed from the atmosphere by reactions with nitric oxide.
The main source of nitrogen oxides in cities is the combustion of fuels by motor vehicles and stationary sources such as industrial facilities. Other industrial processes, such as nitric acid manufacturing facilities, produce nitrogen oxides in air. Urban 8 AIR POLLUTION AND HEALTH IN RAPIDLY DEVELOPING COUNTRIES concentrations tend to be highest near major roads during peak traffic conditions, in the vicinity of major industrial sources and in buildings with unvented sources. Nitrogen oxides are also important indoor air pollutants, as they are produced by domestic and commercial combustion equipment such as stoves, ovens and unflued gas fires.
The first of these chapters draws heavily on recent studies in North America and Europe, while the second synthesizes the evidence from studies in developing countries. Chapters 4, 5 and 6: Tools and approaches to air pollution management. This group includes a chapter describing how international air pollution guidelines and information systems can be used to develop local standards and regulations, a chapter summarizing some of the rapid assessment techniques that can be applied when critical information is lacking, and a chapter on systematic approaches to air quality management.
