Book Description
This book introduces the general principles of reaction equilibria and kinetics involved in marine geochemical cycles. The major electrolytes dramatically affect the rates and equilibria of the chemical reactions in the sea. In order to understand these interactions, it is necessary to have a detailed knowledge of the major, minor and trace chemical components. This volume is also focused on the development and applications of analytical techniques for accurate determination and speciation in seawater, and on the effect of pollution on the marine environment, since small quantities of other elements may have a significant influence on global chemical cycling. Audience: This book is of value for marine chemists, biogeochemists, ecologists, oceanographers, environmental engineers and analytical chemists.

Practical Guidelines for the Analysis of Seawater
Author: Oliver WurlPublisher: CRC Press
ISBN: 9781420073072
Category : Science
Languages : en
Pages : 408
Book Description
As we discover more about the role of the ocean in global changes and identify the effects of global change on the ocean, understanding its chemical composition and processes becomes increasingly paramount. However, understanding these processes requires a wide range of measurements in the vast ocean, from the sea surface to deep-ocean trenches, from the tropics to the poles. Practical Guidelines for the Analysis of Seawater provides a common analytical basis for generating quality-assured and reliable data on chemical parameters in the ocean. A source of practical know-how, the book covers sampling and storage, analytical methodology, and guidelines and procedures for quality assurance. It presents analytical methods with the step-by-step procedures that help practitioners implement these methods successfully into the laboratory, making them instantly applicable without consulting further literature. The book also contains essential information for developing or improving quality control and quality assurance programs in the laboratory. It includes the availability and measurement of standard reference materials, blank estimation and correction, control of recoveries, and statistical evaluation of quality assurance data. Analytical chemistry is a very active and fast moving area. Despite the development of innovative new analytical techniques for chemical trace element research, obtaining reliable data at ultra-trace levels remains a formidable challenge. A complete and practical guide, this book delineates proven methods that consistently yield reproducible data in routine work.

Analysis of Seawater
Author: CromptonPublisher: Elsevier
ISBN: 0323150640
Category : Science
Languages : en
Pages : 432
Book Description
Analysis of Seawater deals with the investigation of the micro-constituents in seawater in terms of nutrient content and environmental concerns. The book describes sampling, determination of anions, analysis of dissolved gases, and metal preconcentration techniques. The book also deals with monitoring radioactive elements, the determination of seawater organics, organometallic compounds, and the oxygen-demand parameters in seawater. It describes in detail surface and deep water sampling, the types of devices used, storage, preservation, and prevention of contamination during sample analysis. In examining dissolved gases, the investigator can use the amperometric titrimetric method (with some reservations) on chlorine, the ultraviolet method on ozone, electron capture gas chromatography on nitric oxide, and also the flow injection analysis on hydrogen sulphide. The methods for determining metals in seawater concern either for single element or for groups of elements. The investigator should always initiate various pre-concentration techniques when determining metals due to their low concentration and occurrence in seawater. The investigator uses various methods to determine different radioactive compounds such as uranium, polonium, thorium, radium, barium, radon, plutonium, strontium-90, and cesium-137. The book can be beneficial for meteorologists, environmentalists, marine ecologists, biologists, oceanographers, fisheries experts, for students studying hydrology, meteorology, as well as for river and lake authorities.
Analysis of Marine Samples in Search of Bioactive Compounds
Author: Publisher: Elsevier
ISBN: 0444633812
Category : Science
Languages : en
Pages : 312
Book Description
Seas and oceans offer a wide range of temperature, pressure, light and chemical conditions thus allowing a wide diversity of marine organisms from shallow coastal waters to the deep ocean. These resources can be used to obtain new products and develop services, and in turn help to provide solutions to the challenges that affect our planet, including offering a sustainable supply of food and energy, new industrial materials and processes, new bioactive compounds, and new health treatments. Marine compounds have been identified as having antibacterial, anticoagulant, antifungal, antimalarial, antiprotozoal, antituberculosis, and antiviral activities. The major sources of these bioactive compounds are marine sponges, coelenterates, and microorganisms, followed by algae, echinoderms, tunicates, molluscs, and bryozoans. The discovery of bioactive compounds from marine samples is a hot topic considering the current need for sustainable use of marine resources. This book is a comprehensive overview of the analytical techniques employed in the discovery and characterization of bioactive compounds isolated from (all possible) marine samples and gives future perspectives of analytical methodologies. This overview includes an assessment of the sampling and preparation of extracts, the separation and isolation of bioactive compounds, their structural characterization and the application of bioassays in the discovery of bioactive compounds. Comprehensive coverage of analytical techniques and applications Clear diagrams to adequately support important topics Real examples of applications of analytical techniques in the search for new bioactive compounds
Chemical Reference Materials

ISBN: 0309085004
Category : Science
Languages : en
Pages : 146
Book Description
The accuracy of chemical oceanographic measurements depends on calibration against reference materials to ensure comparability over time and among laboratories. Several key parameters lack reference materials for measurements in seawater, particles in the water column, and sediments. Without reference materials it is difficult to produce the reliable data sets or long-term baseline studies that are essential to verify global change and oceanic stability. Chemical Reference Materials : Setting the Standards for Ocean Science identifies the most urgently required chemical reference materials based on key themes for oceanographic research and provides suggestions as to how they can be developed within realistic cost constraints. Chemical analyses of seawater are uniquely difficult given the poorly known speciation and the low concentration of many of the analytes of interest. Analyses of suspended and sedimentary marine particulate materials present their own distinct challenges, primarily due to potential interference by predominant mineral phases of different types. Of all the analytical methods applied to marine waters and particles, at present only a small fraction can be systematically evaluated via comparison to reference materials that represent the appropriate natural concentrations and matrices. Specifically, the committee was charged with the following tasks: - compile from available sources a list of important oceanographic research questions that may benefit from chemical reference standards; - create a comprehensive list of reference materials currently available for oceanographic studies; - identify and prioritize the reference materials needed to study the identified research questions; - determine for each priority analyte whether reference materials and/or analytic methods should be standardized; and - identify the most appropriate approaches for the development and future production of reference materials for ocean sciences.
