Air Pollution

Synopsis

Every section of this new edition of Air Pollution has been updated, with particular emphasis on indoor air quality, and a new chapter on Air Pollution Control and Measurement of Industrial Emissions has been added. All references to standards and legislation have been updated in line with the new UK Air Quality Guidelines. Recommended reading lists have also been extended. This new edition continues to cover the wide range of air quality issues in an accessible style. Each topic has an historical introduction, covers the body of generally accepted information, and highlights areas in which developments are currently taking place. Topics covered include the sources and sinks of gaseous and particulate air pollutants, dispersion measurement, mobile sources, indoor air pollutants, and the effects on plants, materials, humans and animals. Local case-studies are referred to, demonstrating the application of theory to practice. Air Pollution is recommended for undergraduate and postgraduate level courses specialising in air pollution, whether from an environmental science or engineering perspective. It will also be of interest to air pollution specialists in consultancies and local authorities.

Excerpt

Air pollution has been with us since the first fire was lit, although different aspects have been important at different times. On the small scale, point source releases of individual pollutants can cause localised responses ranging from annoyance to physical injury. In urban areas, high concentrations of gases and particles from coal combustion and, more recently, motor vehicles have produced severe loss of air quality and significant health effects. On a regional scale, tropospheric ozone formation and acid deposition have been the major threats. Finally, emissions of carbon dioxide and other radiatively active gases, together with stratospheric ozone depletion, represent planet-scale assaults on the quality of our atmospheric environment.

This book is designed to cover the whole gamut of air pollution issues from a quantitative standpoint. In Chapters 1 and 2, the major sources of gaseous and particulate air pollution, together with an outline of possible control measures, are described. Mobile sources, which have taken over from stationary ones as the major threat to local air quality, get their own space in Chapter 3. Chapter 4 describes the most widely-used methods for measuring these pollutants. The temporal and geographical variations of concentrations and deposition on a national and international scale are outlined in Chapter 5. Once released, the effects of these pollutants depend critically on their dilution during dispersion, a process which is covered in Chapter 6. Chapter 7 gives an extended example of the data processing techniques that can be used to extract different types of information from a set of air pollution measurements. Although people tend to associate air quality, or the lack of it, with the outdoors, most of us spend most of our lives indoors, and specific aspects of this specialised environment are highlighted in Chapter 8. The effects of air pollution on plants, animals, materials and visual range are described in Chapters 9 and 10, and the recent issues of climate change and ozone depletion in Chapters 11 and 12. Finally, the effects of pollutants on the environment have led to a wide variety of standards and legislation for their control, and these are reviewed in Chapter 13.

With such a broad spectrum of topics, there is inevitably a considerable variation in the depth of coverage that reflects my own professional interests and experience. I have used as much original research material as possible, since that
