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.

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.

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.

Recent developments clearly indicate that speciation studies in biological and environmental matrices are much more important than the total element determination due to the tremendous difference in bioavailability and toxicity of various chemical forms of a particular element. Different separation-detection techniques and hyphenated systems—each with its own advantages and disadvantages with respect to precision, sensitivity and detection limit—have been developed for the identification and quantification of the species present in systems at ultra-trace levels. This book aims to evaluate the speciation analysis in depth and present a comprehensive review of state-of-the-art analytical approaches used for the speciation of elements in environmental samples.

This book discusses in detail the application of physical separation procedures together with modern instrumental analysis techniques such as HPLC, gas chromatography, and anodic strip-ping voltammetry. Particular emphasis is given to environmental samples where the greatest concern for the effects of speciation on trace element transport, toxicity, and bioavailability have been ex-pressed. Special chapters are also devoted to methods of sam-pling and storage, and to the mathematical modeling of chemical speciation. Although designed for the practical analytical chemist, this publication is essential reading for researchers in or entering the field of chemical speciation.

27th International Congress of Pure and Applied Chemistry is a collection of lectures presented at the 27th Congress of the International Union of Pure and Applied Chemistry, held in Helsinki, Finland, on August 27-31, 1979. The event covers a wide range of topics relating to chemistry, including biotechnology and bioengineering; trace element analysis; modern methods in clinical chemistry; and analysis and structure of cell membrane carbohydrates. Chemometrics is also discussed, along with the chemistry and technology of natural polymers and their degradation products. This book consists of 36 chapters and opens with an assessment of prospects for biotechnology amid the resource problems facing industrialized countries. The reader is then introduced to the main principles of screening effective anticancer drugs based on the methods and concepts of biology, chemistry, physics, and mathematics; the fundamental principles involved in steroid immunoassay for clinical chemistry applications; fractionation and determination of trace elements in plants, soils, and sediments; and trace metal analysis in exploration geochemistry. The following chapters explore clinical applications of steroid hormone receptor assays; asparagine-linked sugar chains of glycoproteins; chemistry and technology of starch; and use of high-performance liquid chromatography in the analysis of red blood cell glycolipids. This monograph will be a valuable source of information for practitioners and research workers in the field of pure and applied chemistry.

Mercury pollution and contamination are widespread, well documented, and continue to pose a public health concern in both developed and developing countries. In response to a growing need for understanding the cycling of this ubiquitous pollutant, the science of mercury has grown rapidly to include the fields of biogeochemistry, economics, sociology, public health, decision sciences, physics, global change, and mathematics. Only recently have scientists begun to establish a holistic approach to studying mercury pollution that integrates chemistry, biology, and human health sciences. Mercury in the Environment follows the process of mercury cycling through the atmosphere, through terrestrial and aquatic food webs, and through human populations to develop a comprehensive perspective on this important environmental problem. This timely reference also provides recommendations on mercury remediation, risk communication, education, and monitoring.
