Contents of the book are organized under sections and sub-sections and topics in a systematic way. Each section comprises interrelated chapters. Several sections (each comprising several chapters) are devoted to particular systems, with interconnectivity between various sections and chapters. An overview of each section highlights the essential features of the chapters in that section with a common theme. List of abbreviations, appendices, glossary and index are included to facilitate the reader an easy access to concepts and technical terms. This book, with an integrated and quantitative approach towards the subject, would fulfill the needs of students and researchers in diverse fields in environmental science at the graduate and research levels in the university /academic institutions. It can also serve as a supplementary sourcebook for biophysics, physics, chemistry, biotechnology, life sciences and other subjects, whose converging interest is in environmental science.</span><br></p>
