Elements of Environmental Chemistry

A practical approach to environmental chemistry, Elements of Environmental Chemistry, 3^rd Edition provides readers with the fundamentals of environmental chemistry and a toolbox for putting them into practice. This is a concise, accessible, and hands-on volume designed for students and professionals working in the chemical and environmental sciences.

The 3^rd Edition has been completely revised and rearranged. The first chapter on tool skills has been expanded to include thermodynamic considerations and measurement issues. The former chapter on the partitioning of organic compounds has been expanded to cover the fates of organic compounds, with an emphasis on developing the readers chemical intuition for predicting a chemicals fate based on structure. The material on lead, mercury, pesticides, PCBs, dioxins, and flame retardants has been expanded and combined into the last chapter and supplemented with more references to the literature. The problem sets have been extended and now include over 130 problems, some of which can be solved using Excel.

Jonathan D. Raff, PhD, is an Associate Professor in the O'Neill School of Public and Environmental Affairs at Indiana University. He was the recipient of a National Science Foundation American Competitiveness in Chemistry Fellowship and early career awards from the National Science Foundation and the U.S. Department of Energy.

Ronald A. Hites, PhD, is a Distinguished Professor Emeritus in the O'Neill School of Public and Environmental Affairs at Indiana University. He is a Fellow of the American Chemical Society, of the American Association for the Advancement of Science, and of the Society for Environmental Toxicology and Chemistry.
