"This book deals comprehensively with the five essential cycles or environspheres - lithosphere (minerals and energy sources), atmosphere (air), hydrosphere (water), pedosphere (soil) and biosphere (life), with an overview of their interactions. It covers the chemistry of energy sources and aspects of biochemistry, geochemistry and toxicological chemistry in addition to the three important areas of air, water and soil chemistry, linking in the process chemical principles with environmental issues. With the fundamental principles presented clearly and topics covered in logical sequence, this book can be used as a textbook for a course in environmental engineering or environmental science. It can also serve as a reference text for professionals in the field. "--BOOK JACKET.
