This textbook covers the entire spectrum of topics required to completely understand air pollution. It emphasizes the atmospheric processes governing air pollution (emissions, atmospheric dispersion, chemical transformations, deposition on surfaces and ecosystems). Other areas of focus include air pollutant emission control technologies, health and environmental impacts, regulations and public policies, and interactions between climate change and air pollution. Topics are first presented conceptually, and then in terms of their fundamental aspects. Actual case studies are incorporated throughout to illustrate major air pollution phenomena, such as the dispersion of pollutants in the atmosphere, and the development of strategies to reduce urban air pollution, mitigate acid rain, and improve atmospheric visibility. Graduate students, researchers, and air quality professionals will find the full coverage of these important matters to be well suited to their needs.
