Includes access to the Student Companion Website Appropriate for students with a general chemistry background, Principles of Environmental Chemistry helps students understand the underlying chemical processes that are operating in the environment while demonstrating how difficult it is to measure these systems. The author emphasizes that all living and nonliving parts of our environment are comprised of chemicals and that all of the natural processes continuously occurring in the environment involve chemical reactions. With this concept of interdependence, students begin to see that without some understanding of chemistry, it is impossible to fully understand environmental issues such as ozone depletion, global warming, air and water pollution, and the hazards of radioactivity.
