Understanding Environmental Pollution has been updated and almost completely revised. The book summarizes the basics of pollution, working to use language understandable to those with limited science background, while remaining useful to those with more. The impacts of pollution on environmental health receive greater attention in this edition, and there are more case descriptions, which pose reflective questions to the reader. The second edition also has greater emphasis on pollution problems in less-developed nations. It often delves too into pollution that moves beyond national boundaries. In addition, more references are included at the end of chapters, including many web sites.
