PREFACE TO THE SEVENTH EDITION Emvironmental chemistry, Seventh Edition, continues much the same organizational structure, level, and emphasis that have been developed through preceding editions. In addition to providing updated material in the rapidly developing area of environmental chemistry, this edition emphasizes several major concepts that are proving essential to the practice of environmental chemistry at the beginning of the new millennium. These include the concept of the anthrosphere as a distinct sphere of the environment and the practice of industrial ecology sometimes known as green chemistry" as it applies to chemical science Chapter I serves as an introduction to environmental science, technology, and chemistry. Chapter 2 defines and discusses the anthrosphere, industrial ecosystems and their relationship to environmental chemistry. Chapters 3 through 8 deal with aquatic chemistry Chapters 9 through 14 discuss atmospheric chemistry. Chapter 14 emphasizes the greatest success story of environmental chemistry to date, the study of ozone depleting chlorofluorocarbons which resulted in the first Nobel prize awarded in environmental chemistry. It also emphasizes the greenhouse effect, which may be the greatest of all threats to the global environment as we know it Chapters 15 and 16 deal with the geosphere, the latter chapter emphasizing soil and agricultural chemistry. Included in the discussion of agricultural chemistry is the important and controversial new area of of transgenic crops. Another area discussed is that of conservation tillage, which makes limited use of herbicides to grow crops with minimum soil disturbance Chapters 17 through 20 cover several aspects of industrial ecology and how relates to material and energy resources, recycling, and hazardous waste Chapters 21 through 23 cover the biosphere. Chapter 21 is an overview of biochemistry with emphasis upon environmental aspects. Chapter 22 introduces and outlines the topic of toxicological chemistry. Chapter 23 discusses the toxicological chemistry of various classes of chemical substances Chapters 24 through 27 deal with environmental chemical analysis, including ter wastes, air and xenobiotics in biological materials The last two chapters of the book, 28 and 29 include an overview of general o 2000 CRC Press llcPREFACE TO THE SEVENTH EDITION __________________________ __________________________ Environmental chemistry, Seventh Edition, continues much the same organizational structure, level, and emphasis that have been developed through preceding editions.
