The Second Edition of Principles of Environmental Chemistry provides students with the tools they need to understand the underlying chemical processes operating in the environment, while demostrating how challenging it is to measure these systems. Written for students with a knowledge of general chemistry, this text emaphsizes that all living and non-living parts of our environment are made up of chemical matter, and the natural procsses continuously occurring in the environment all involve chemical reactions. With this concept of interdependence students willï begin to understand pressing environmental issues like ozone depletion, global warming, air and water polution, and the hazards or radioactivity.
