The analysis of soils and sediments for pollutants is increasingly required in today's industrial world. It is therefore important that extraction procedures used for environmental risk assessment studies, production of certified reference materials and applications of extraction schemes are standardised throughout the scientific community. This book deals specifically with operationally-defined extraction methods for the determination of "fractions" of elements in soil and sediment matrices. Bringing together the work of a number of different international laboratories, the book describes single and sequential extraction procedures. It then goes on to present a summary of the latest research on extraction/leaching tests for the determination of trace organic compounds in wastes, followed by an outline of an international network which aims to standardise extraction and leaching methodologies for their applications to various environmental matrices. Methodologies for Soil and Sediment Fractionation Studies will be welcomed by researchers and analysts in academia, industry and government institutions worldwide.

This is the first interdisciplinary book on the mobilization of nutrients and pollutants in the water phase due to hydrodynamic processes. Coverage includes the formation of aggregates in turbulent water; flocks and biofilms from organic reactions; and the formation of new surfaces for re-adsorption of dissolved pollutants. The book gathers papers resulting from an International Symposium on Sediment Dynamics and Pollutant Mobility in River Basins in Hamburg, Germany, March, 2006.

This book covers all aspects of bioavailability, as related to environmental contaminants. After a discussion of the definition of bioavailability and its context, focus is placed on the role of risk assessment and bioavailability. Methods of analysis are then discussed including a range of atomic spectroscopic and electrochemical techniques for metal analysis and chromatographic approaches for persistent organic pollutants (POPs). The occurrence, properties and eco-toxicity of POPs and metals in the soil/sediment environment are discussed. Particular emphasis is placed on the uptake of POPs and metals by plants (phytoextraction). Examples of POPs and metals in the environment are reviewed. Methods to assess the bioavailability of POPs and metals in the environment are discussed. The particular approaches considered are: non-exhaustive extraction techniques single extraction techniques sequential extraction techniques use of cyclodextrin and surfactants in-vitro gastrointestinal methods including physiological-based extraction test the use of bioasssays including earthworms. Finally, selected case studies highlight the importance of determining the bioavailability of POPs and metals.

This edited book, Soil Contamination - Current Consequences and Further Solutions, is intended to provide an overview on the different environmental consequences of our anthropogenic activities, which has introduced a large number of xenobiotics that the soil cannot, or can only slower, decompose or degrade. We hope that this book will continue to meet the expectations and needs of all interested in diverse fields with expertise in soil science, health, toxicology, and other disciplines who contribute and share their findings to take this area forward for future investigations.

Fractionation, in the most general sense, could mean any process whereby a mixture is separated into different components or fractions. Examples of fractionation processes include dephlegmation, fractional distillation, fractional freezing, fractional melting, isotope fractionation, and other separation techniques. Of the many and varied separation processes available, fractionation plays a major part, and capital investment in fractionation equipment and processes may form a significant fraction of industrial processing investment. Fractionation as a separation technique is extensively used in widely diverse areas such as the application of geochemical fractionation of metals in sediments of water reservoirs, fractionation of polysaccharides from selected mushroom species, and fractional distillation of bio-oil produced by pyrolysis of certain palm seeds.

Bioavailability refers to the extent to which humans and ecological receptors are exposed to contaminants in soil or sediment. The concept of bioavailability has recently piqued the interest of the hazardous waste industry as an important consideration in deciding how much waste to clean up. The rationale is that if contaminants in soil and sediment are not bioavailable, then more contaminant mass can be left in place without creating additional risk. A new NRC report notes that the potential for the consideration of bioavailability to influence decision-making is greatest where certain chemical, environmental, and regulatory factors align. The current use of bioavailability in risk assessment and hazardous waste cleanup regulations is demystified, and acceptable tools and models for bioavailability assessment are discussed and ranked according to seven criteria. Finally, the intimate link between bioavailability and bioremediation is explored. The report concludes with suggestions for moving bioavailability forward in the regulatory arena for both soil and sediment cleanup.

Carbon stored in soils represents the largest terrestrial carbon pool and factors affecting this will be vital in the understanding of future atmospheric CO2 concentrations. This book provides an integrated view on measuring and modeling soil carbon dynamics. Based on a broad range of in-depth contributions by leading scientists it gives an overview of current research concepts, developments and outlooks and introduces cutting-edge methodologies, ranging from questions of appropriate measurement design to the potential application of stable isotopes and molecular tools. It includes a standardised soil CO2 efflux protocol, aimed at data consistency and inter-site comparability and thus underpins a regional and global understanding of soil carbon dynamics. This book provides an important reference work for students and scientists interested in many aspects of soil ecology and biogeochemical cycles, policy makers, carbon traders and others concerned with the global carbon cycle.

It is only with the ending of the Cold War that the issue of environmental hazards at many former nuclear testing sites around the world has attracted international scientific interest. This book discusses the environmental, ecological, and health problems associated with nuclear testing. Topics treated include dose assessment, risk, speciation and transport of radionuclides, measurement and separation of radionuclides, and remedial options. The nuclear test sites examined include the Semipalatinsk Nuclear Test Site (Kazakhstan), the Nevada test Site (USA), the Pacific atolls, and the Maralinga Test Site (Australia). The volume also discusses the additional release sites of Chelyabinsk (Russia), Chernobyl (Ukraine), Palomares (Spain), Los Alamos (USA), and others. A valuable compendium of radiological problems for a wide spectrum of readers, from non-specialist to expert.
