This reference takes a quantitative approach to environmental chemistry, employing a concise style. The second edition continues the book's original approach, while adding important topics such as climate change, atmospheric chemisty, the reactive fates of organic compounds and organic pollutants associated with oil spills, and the Stockholm "dirty dozen" (DDT, PCBs and dioxins). With new real-world problems added throughout, this updated text provides a short, quantitative resource ideal for an introductory course in environmental chemistry, as well as a quick primer on the subject for professionals.
