Principles of Environmental Chemistry is a student-friendly presentation of the chemical foundations of contemporary environmental issues and science. Written for students with a knowledge of general chemistry, this text builds on that experience as it explores and discusses major environmental themes such as the greenhouse effect, chemistry of the ozone hole, acid rain, water pollution, and the impact of humans on the environment. Principles of Environmental Chemistry is the only environmental chemistry textbook that stresses the analytical techniques and methods used by the EPA to measure pollutants in the environment and describes EPA regulation of discharges into the air, water, and soil. It covers, in detail, the instruments and techniques used by the EPA to assure compliance. With this knowledge, students are better able to understand the chemical composition of an unpolluted environment.
