The scientific study of the biochemical and chemical phenomena which take place in natural places is known as environmental chemistry. Some of the various areas studied under this discipline are reactions, their effects and sources, along with the effects of biological and human activity on soil, air and water. It is an interdisciplinary science which combines elements from aquatic, soil and atmospheric chemistry. Environmental chemistry plays an integral role in the detection and identification of the source and nature of pollutants in varied areas. This field also makes use of several quantitative chemical analytical methods such as electrochemical, titrimetric and gravimetric methods. This book provides significant information of this discipline to help develop a good understanding of environmental chemistry. It covers in detail some existent theories and innovative concepts revolving around this field. Those in search of information to further their knowledge will be greatly assisted by this book.
