The branch of science which focuses on all the chemical and biochemical events which occur in natural places is known as environmental chemistry. It attempts to study the reactions, sources, effects, transport of the chemical species which are present in the soil, water and air. It also deals with the effects of human activities and biological activities on these systems. Environmental chemistry is a multidisciplinary field which encompasses the principles of soil chemistry, atmospheric chemistry and aquatic chemistry. It finds applications in the detection of pollutants such as heavy metals, aromatic carbons and organometallic compounds in water bodies and organic systems. Phenomenon such as algal bloom and eutrophication are also studied under it. The topics included in this book on environmental chemistry are of utmost significance and bound to provide incredible insights to readers. Its objective is to give a general view of the different areas of environmental chemistry, and its applications. Those in search of information to further their knowledge will be greatly assisted by this book.
