'Spiro, Purvis-Roberts and Stigliani write in a clear and engaging style. They organize the material in a logical and compelling manner, emphasizing the many cross-connections among environmental topics. The bottom line is that this is the environmental chemistry book that we have all been waiting for!' - From Foreword by Harry Gray, California Institute of Technology, USA 'I very much congratulate the authors. This is by far the best environmental chemistry text that I have read.' - Professor John Perona, University of California at Santa Barbara, USA 'The authors provide clear and concise explanations and do a good job of integrating calculations throughout the book. This book is useful both for students learning to apply chemical concepts to understand the environment and for instructors seeking a distinct perspective and important data on the environment.' - Professor Keith Kuwata, Macalester College, USA 'No other text in environmental chemistry so nicely balances breadth, depth and readability.' - Professor A.D. Anbar, Arizona State University, USA
