Bioavailability of Contaminants in Soils and Sediments
Author: National Research CouncilPublisher: National Academies Press
ISBN: 0309086256
Category : Technology & Engineering
Languages : en
Pages : 433
Book Description
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.
Sediment Classification Methods Compendium

ISBN:
Category : Environmental protection
Languages : en
Pages : 234
Book Description
This document is a compendium of scientifically valid and accepted methods that can be used to assess sediment quality and predict ecological impacts...the intent here is to provide the most useful overall measures or predictors of ecological impacts currently in use rather than procedures that may have limited application outside of a particular regulatory framework... parag The information provided in the compendium on the relative strengths and weaknesses of the different assessment methods can provide assistance in selecting the appropriate methods.
Sediment/Water Interactions

Category : Science
Languages : en
Pages : 733
Book Description
The papers appearing in this volume reflect the current attention in sediment/water science to five main topics of investigation: Sediment dynamics in estuaries, coastal waters, lakes, reservoirs and rivers; Sediment-associated biological processes; Contaminant accumulation, distribution and geochemistry; Fluxes from sediments; and Element cycling. Contributors address sediment/water interactions related to both fresh and salt water conditions.

Book Description
Introduction The Fourth Symposium on Sediment/Water Interactions was held in Melbourne, Australia, February 16-20th, 1987. The previous three symposia were held in Amsterdam, Kingston (Ontario), and Geneva, In keeping with the approach established in Geneva, contributions addressed sediment/water interactions related to both fresh and salt water conditions. More than 160 papers were given in Melbourne, including more than 20 poster presentations, and collected Abstracts are available from Dr. B. T. Hart. A total of 51 papers, subsequently, have been published as proceedings of the Melbourne Symposium; 45 of these appear in this issue of Hydrobiologia. A further six appeared earlier as a selection of papers in J. Environ. Geol. and Water Science (1988, issue # 1); these six papers appear in abstract form, only, in the present pUblication. Although concerned with the global environment, the International Association for Sediment Water Science attempts to ensure that there is a genuine opportunity for participants to focus on regional issues throughout the world and, in particular, to provide a local forum for their presentation. The Melbourne meeting was particularly successful in achieving this objective, and Australasia was well represented by about 36 percent of the contributors. About 27 percent were from Europe, 17 percent from North America, 7 percent from China and Japan, 7 percent from Southeast Asia and India, and about 6 percent came from other areas. In all, 25 countries were represented.
Methods for Assessing the Toxicity of Sediment-associated Contaminants with Estuarine and Marine Amphipods
Author: Transport and Transformation of Contaminants Near the Sediment-Water Interface
Author: Joseph V. DePintoPublisher: CRC Press
ISBN: 9780873718875
Category : Science
Languages : en
Pages : 372
Book Description
Transport and Transformation of Contaminants Near the Sediment-Water Interface addresses the issue of contaminated bottom sediments and their potential adverse impacts on water quality. This state-of-the-science book covers regulatory management perspectives, physical processes, chemical and biological processes, and process synthesis/modeling. Specific topics discussed include EPA's Sediment Quality Criteria program from a regulatory perspective; flocculation, deposition, and resuspension of fine-grained sediments; approaches for measuring vertical sediment flux near the sediment-water interface; equilibrium models for metal speciation in natural sediments; the partitioning of organic chemicals in bottom sediments; and the development and application of models of sediment and associated contaminant transport in surface waters. The significance of recent studies suggesting that interaction of contaminated bottom sediments with the overlying water play an important role in the long-term recovery of aquatic systems makes Transport and Transformation of Contaminants Near the Sediment-Water Interface essential for water quality engineers, environmental chemists, and environmental toxicologists. The volume provides important information for consultants, regulators, researchers, and graduate students as well.
