This book was released on 2003 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: This document was prepared to describe the process that was used to establish & evaluate the effects-based sediment quality criteria for managing contaminated sediments in British Columbia. The report begins with an introduction on the role of sediments in freshwater ecosystems, the issues & concerns related to sediment quality, and the sediment-associated chemical contaminants that are of potential concern in the province. Chapter 2 describes the existing provincial framework for managing contaminated sites and chapter 3 reviews the various approaches that could be used for establishing numerical sediment quality criteria for freshwater, estuarine, & marine ecosystems. Chapter 4 explains the procedures used to derive numerical sediment quality criteria for assessing & managing sediment contaminated sites in British Columbia. Results of evaluations conducted to assess the reliability of sediment quality criteria are presented in chapter 5. The final chapter discusses applications of the sediment quality criteria in such areas as site screening, site investigation, design of sampling programs, identifying risk levels, and establishing site management goals & remediation targets.

Download or read book Sediment Quality Assessment written by Graeme Batley and published by CSIRO PUBLISHING. This book was released on 2016-02-01 with total page 332 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contaminated sediments represent an ongoing threat to the health of aquatic ecosystems. The assessment of sediment quality is, therefore, an important concern for environmental regulators. Sediment quality guidelines are now well established in regulatory frameworks worldwide; however, practical guidance that covers all of the key aspects of sediment quality assessment is not readily available. In 2005, CSIRO published its highly cited Handbook for Sediment Quality Assessment. In the ensuing period, the science has advanced considerably. This practical guide is a revised and much expanded second edition, which will be a valuable tool for environmental practitioners. Written by experts in the field, it provides coverage of: sediment sampling; sample preparation; chemical analysis; ecotoxicology; bioaccumulation; biomarkers; and ecological assessment. In addition, detailed appendices describe protocols for many of the tests to be used.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Although bioaccumulation of polychlorinated biphenyls (PCBs) in food webs is well-recognized, this phenomenon is not currently incorporated into the methodology for developing sediment quality guidelines (SQGs) in British Columbia. The aim of this study is to develop and apply an empirical and modelling approach to the development of sediment quality criteria for the protection of marine mammals, using harbour seal pups as a proxy. An average empirical Biota-Sediment Accumulation Factor (BSAF) of 490 (lower SD 220, upper SD 1100) g-dry-weight sediment/ g-lipid-weight biota (n=6) was calculated for VPCBs, which was overestimated by the model predication (BSAF of 1000 g-dry-weight sediment/ g-lipid-weight biota). Using the empirical BSAF and a Threshold Effects Concentration (TEC) of 1.3 og PCB/g lipid, a SQG for VPCBs of 0.82 ng/g dw is proposed in order to protect 95% of the pup seal population, which is not being achieved by the current SQG of 20 ng/g dw.

Book excerpt: In this text, drawn from presentations and discussion at a May 2005 NATO Advanced Research Workshop, current approaches to the assessment and remediation of contaminated sediments are discussed with emphasis on in-situ management. The text addresses physical, chemical and biological approaches for the assessment and remediation of sediments. The development of regulatory and strategic approaches is discussed with emphasis on the potential for biological remediation in the management of contaminated sediments.

This book was released on 1992 with total page 234 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The study of estuaries and coasts has seen enormous growth in recent years, since changes in these areas have a large effect on the food chain, as well as on the physics and chemistry of the ocean. As the coasts and river banks around the world become more densely populated, the pressure on these ecosystems intensifies, putting a new focus on environmental, socio-economic and policy issues. Written by a team of international expert scientists, under the guidance of Chief Editors Eric Wolanski and Donald McClusky, the Treatise on Estuarine and Coastal Science, Ten Volume Set examines topics in depth, and aims to provide a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Most up-to-date reference for system-based coastal and estuarine science and management, from the inland watershed to the ocean shelf Chief editors have assembled a world-class team of volume editors and contributing authors Approach focuses on the physical, biological, chemistry, ecosystem, human, ecological and economics processes, to show how to best use multidisciplinary science to ensure earth's sustainability Provides a comprehensive scientific resource for all professionals and students in the area of estuarine and coastal science Features up-to-date chapters covering a full range of topics
Download or read book Developing Ecosystem Based Sediment Quality Guidelines in British Columbia written by Jennifer Anne Arblaster and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment Quality Guidelines (SQG) that do not account for biomagnification of chemicals in marine food chains, may be insufficiently protective of upper trophic level organisms. Biota-Sediment Accumulation Factors (BSAF=C[subscript {biota}]/C[subscript {sediment}]) quantify the relationship between concentrations in organisms and the sediment and can be applied to derive SQGs that account for biomagnification. PCB data for four sites on the B.C. coast were used to derive BSAFs. BSAF were used to assess risks to upper trophic level populations from current SQG and to derive new SQG. Bioaccumulation modeling derived BSAFs for additional species and human health risk assessment. Applying BSAFs shows that current guidelines fail to protect Orca whale, Steller sea lion and harbor seal populations or human health. SQGs back-calculated from relevant endpoints for human health, marine mammal, birds and salmon population health were all under 1 og/kg dw -- substantially lower than the current B.C. SQG of 20 og/kg dw.
