This is the first publication to offer a comprehensive and balanced view of atmospheric acidity. It is organised in three sections. The first part consists of reviews of sources of acidic compounds, the second part outlines the environmental consequences and the final part discusses the technological, legal and political aspects of control strategies.

The contributing authors have been chosen because of their depth of knowledge and experience in air pollution work, and we are confident that this is reflected in a Handbook which will find very wide application wherever air pollution analysis is practised. Roy M. Harrison Roger Perry February 1985 Readers are recommended to follow all the usual laboratory safety pre cautions. While care has been taken to ensure that the information in this book is correct, neither the authors nor the publisher can accept responsibility for any outcome of the application of methods and procedures outlined in this book.

The new edition of this textbook introduces the basic chemical concepts underlying a sound understanding of environmental science and ecology. Chapters contain explanations of fundamental chemical principles and include illustrations of real examples from the environment. From an introduction to atomic and molecular structure, the text progresses to more advanced areas within physical, inorganic, organic, and analytical chemistry. Important new sections include an introduction to the concepts of biogeochemical cycling, and the role environmental chemistry plays with respect to climate, notably global warming and ozone depletion. The case studies have been updated, and a section about toxic chemicals has been added. While the primary aim is to satisfy the needs of the nonchemist, the text also serves to introduce environmental precepts to chemists who wish to apply their expertise to environmental issues. This volume is especially suitable for undergraduates in environmental science, environmental chemistry and ecology.
