This reference bridges the gap between popular mainstream articles, highly technical publications, and research journals dealing with air quality. The second edition of Principles of Air Quality Management features new sections on air toxics, new information on chronic and acute health effects, and new approaches to the assessment of those impacts on sensitive populations. It emphasizes toxic air pollutants and alternative approaches to management of air quality in local environments. The book explains how primary pollutants form in industrial and mobile combustion processes and the latest on how they are controlled. It also presents in-depth information on the meteorology of atmospheric transport and explains how secondary photochemical pollutants form in ambient air.
