Environmental Soil Chemistry is the only text available that covers the essentials of the topic plus provides information on the latest technological advances that represent the cutting edge of the science. - Gary M. Pierzynski, Professor at Kansas State University and Editor of Journal of Environmental Quality Professor Sparks does an excellent job in relating environmental applications to the more theoretical topics of soil chemistry. The second edition has been notably expanded for several topics including advanced analytical methods. Students in environmental sciences, environmental geochemistry, and soil science will find the book a highly instructive resource. - Harvey E. Doner, University of California at Berkeley "This text is a concise and authoritative introduction to the field of Environmental Soil Chemistry that is very suitable for a one semester course. The second edition is replete with crisp graphics and real world examples that lay out the foundations of soil chemistry, while providing a firm basis for illustrating the emergence in our field of cutting-edge techniques in molecular spectroscopy and kinetics." - Jon Chorover, University of Arizona, Tucson
