This book was released on 1994 with total page 150 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment contamination is a widespread environmental problem that can potentially pose a threat to a variety of aquatic ecosystems. The sediment test methods in this manual will be used by The United States Environmental Protection Agency (USEPA) to make decisions under a range of statutory authorities concerning such issues as: dredged material disposal, registration of pesticides and toxic substances, superfound site assessment, and assessment and cleanup of hazardous waste treatment, storage, and disposal facilities. The use of uniform sediment testing procedures by USEPA programs is expected to increase data accuracy and precision, facilitate test replication, increase the comparative value of test results, and ultimately, increase the efficiency of regulatory processes requiring sediment tests.

Download or read book Sediment Toxicity Assessment written by G.Allen Burton and published by CRC Press. This book was released on 2018-05-04 with total page 480 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sediment Toxicity Assessment provides the latest information regarding how to evaluate sediment contamination and its effects on aquatic ecosystems. It presents an integrated ecosystem approach by detailing effective assessment methods, considerations, and effects to each major component of marine and freshwater systems, including the benthos, plankton, and fish communities. The approaches emphasize defining habitat conditions (physical and chemical), toxicant bioavailability, factors influencing toxicity (lab and field), biomarkers, acute and chronic toxicity, study design, collection methods, and EPA management strategies. The book also explains how to integrate the assessments. Sediment Toxicity Assessment will be useful to to all environmental managers, environmental scientists, ecotoxicologists, environmental regulators, aquatic ecologists, environmental contractors and consultants, instructors, students, conservation commissions, and environmental activist organizations.

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.
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.

Download or read book Sediments written by Renato Baudo and published by CRC Press. This book was released on 2020-01-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This important volume-the product of a meeting of a select group of scientists-provides the most recent research results from the world's leaders in the study of toxic pollutants in sediments. It gives practical information on measuring and mapping distributions of concentrations of pollutants and their toxic effects in sediments. Also covered are the use and relative advantages and disadvantages of benthic chambers, sedimentation traps, box corers, "peepers" and other sampling techniques in sediment research and assessment. Important topics covered include: bioassay, elemental speciation, diffuse source problems, nutrient flux, biomethylation, bioavailability, and toxicity assessment. Will help in assessment and monitoring of chemistry, dynamics, bioavailability, and toxicity of pollutants, as well helping to chart courses for remedial action. This book will be of interest to anyone interested in the processes controlling the chemistry and movement of pollutants in sediments, especially: limnologists aquatic toxicologists engineers lake managers ecologists biologists environmental chemists
Download or read book Clean Coastal Waters written by National Research Council and published by National Academies Press. This book was released on 2000-07-17 with total page 421 pages. Available in PDF, EPUB and Kindle. Book excerpt: Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Available in PDF, EPUB and Kindle. Book excerpt: Since the early 1970s, experts have recognized that petroleum pollutants were being discharged in marine waters worldwide, from oil spills, vessel operations, and land-based sources. Public attention to oil spills has forced improvements. Still, a considerable amount of oil is discharged yearly into sensitive coastal environments. Oil in the Sea provides the best available estimate of oil pollutant discharge into marine waters, including an evaluation of the methods for assessing petroleum load and a discussion about the concerns these loads represent. Featuring close-up looks at the Exxon Valdez spill and other notable events, the book identifies important research questions and makes recommendations for better analysis ofâ€"and more effective measures againstâ€"pollutant discharge. The book discusses: Inputâ€"where the discharges come from, including the role of two-stroke engines used on recreational craft. Behavior or fateâ€"how oil is affected by processes such as evaporation as it moves through the marine environment. Effectsâ€"what we know about the effects of petroleum hydrocarbons on marine organisms and ecosystems. Providing a needed update on a problem of international importance, this book will be of interest to energy policy makers, industry officials and managers, engineers and researchers, and advocates for the marine environment.
Download or read book Toxicity of U S Waterway Sediments with Particular Reference to the New York Harbor Area written by RA. Jones and published by . This book was released on 1988 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: A study was conducted in the mid- to late-1970s on the toxicity of elutriate test mixtures of water and sediment from U.S. harbors and waterways to grass shrimp or daphnia. While for many waterway sediments, 20 to 30% mortality was found after 96-h exposure, those of the New York harbor area showed somewhat greater toxicity. The specific cause of the mortalities was not investigated at that time. It is known that the sediments contained a wide variety of chemical contaminants which, if available to the organisms, could be toxic to them. More than 30 chemical parameters, including heavy metals and chlorinated hydrocarbon pesticides, were measured in the sediments; of the parameters measured, only ammonia was released in sufficient amounts to potentially cause acute lethality in the test waters associated with the sediments. Recent review of the data showed that there is a relationship between the concentration of ammonia in the sediment/water mixtures (elutriates) and the mortality of grass shrimp in the tests. Furthermore, the concentrations that appeared to cause about 50% mortality of the grass shrimp in the 96-h exposure were about the level of 96-h LC50 to grass shrimp for ammonia.
