Produktbeschreibung

A modern guide to environmental chemistry

Chemistry of Environmental Systems: Fundamental Principles and Analytical Methods offers a comprehensive and authoritative review of modern environmental chemistry, discussing the chemistry and interconnections between the atmosphere, hydrosphere, geosphere and biosphere. Written by internationally recognized experts, the textbook explores the chemistries of the natural environmental systems and demonstrates how these chemical processes change when anthropogenic emissions are introduced into the whole earth system.

This important text:
_ Combines the key areas of environmental chemistry needed to understand the sources, fates, and impacts of contaminants in the environment
_ Describes a range of environmental analytical methodologies
_ Explores the basic environmental effects of energy sources, including nuclear energy
_ Encourages a proactive approach to environmental chemistry, with a focus on preventing future environmental problems
_ Includes study questions at the end of each chapter

Written for students of environmental chemistry, environmental science, environmental engineering, geoscience, earth and atmospheric sciences, Chemistry of Environmental Systems: Fundamental Principles and Analytical Methods covers the key aspects and mechanisms of currently identified environmental issues, which can be used to address both current and future environmental problems.
