The presence of concentrations of organic substances and cations in seawater is a matter of increasing concern to the water industry, environmentalists and the general public alike. It poses a threat of possible health hazards for humans, fish and crustacea. Until fairly recently, the analysis of seawater was limited to a number of major constituents such as chloride and alkalinity. Insufficient attention was given to the analysis of sediments. Analysis of Oceanic Waters and Sediments draws attention to the methods available for analysing sediments in seawater. It covers classical methods as well as the most advanced and recently introduced physical techniques. It also discusses the sensitivities and limitations of the methods. The book is comprised of two major components. The first is a review of the occurrence of organic compounds and cations as well as examples of pollution by these substances in the ocean. The second is concerned with determination of the concentrations of organic compounds and metals, including an in-depth examination of the most sensitive analytical methods that are available and necessary for detecting them due to their low concentrations in the ocean. A detailed exploration of the largely overlooked area of oceanic sediment analysis, this book is of high interest for all professionals in the water industry, from river management to fish industries, sewage effluent treatment and disposal, land drainage and water supply. Its scope also applies to agriculturalists, chemists, biologists, toxicologists, public health workers and public analysts.

This book is intended for both the undergraduate and postgraduate levels. The subject material deals with symmetry, starting from the basic and rudimental foundations of the concept and the depth of its applications. The presentation of the concepts and the related illustrations in the book are on semi-pedagogical lines and thus offer easy understanding to the reader. The book is designed with twelve well thought chapters, with each preceding chapter opening the gate for the development of the next thereby having a high degree of sequence.The first seven chapters are devoted to the indepth understanding of 'symmetry and group theory' of molecules and the last five chapters are developed on the aspects of how these formalisms are utilized for the 'structure, spectra and bonding' of molecules. The book also covers the essential basics of the group theory that are required for all sections of chemistry, and emphasizes the necessity of this theory to understand the theoretical and applied aspects of molecular spectroscopy. This text is the result of a long felt need for developing certain novel techniques for the teaching of this course. A 'Window-vision' has been provided in the book while presenting most of the chapters and 'Study Questions' are placed at the end of each chapter to help ensure understanding of the concepts. 'No more nightmares of group theory and spectroscopy' - is the ultimate purpose of this book.
