<P>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.</P><B><P>Analysis of Oceanic Waters and Sediments</B> 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.</P><P>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 con
