Download or read book Methods for Measuring the Toxicity and Bioaccumulation of Sediment-associated Contaminants with Freshwater Invertebrates written by and published by . 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.

This book was released on 2005 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Existing ecotoxicity data for chemicals vary to a high extent between the environmental compartments water and sediment, since the evaluation of contaminants has historically focused on water exposition. Many anthropogenic chemicals and waste materials, including toxic organic and inorganic chemicals, adsorb to particulate matter and accumulate in sediments, and may thus be a threat to organisms living in the sediment. The invertebrates Chironomus riparius and Lumbriculus variegatus were selected as representatives of endobenthic living organisms. Acute toxicity tests, via water-only exposure, and sediment toxicity tests were conducted with the two endobenthic invertebrates. In sediment toxicity tests, organisms are mainly exposed to sediment- and particle-bound chemicals and dissolved chemical in the pore water. Toxicity data for algae, daphnids, and fish (via water-only exposure) are available for many substances, whereas the existing sediment toxicity data are rather rare. Thus, the interest arises to predict sediment toxicity for sediment-dwelling invertebrates from existing acute toxicity data of tests with water-only exposure. The main emphasis of this work was placed on one metal compound and seven organic chemicals. The objective of this study was fivefold: (1) develop methods and improve existing procedures on acute and sediment toxicity testing of the two invertebrates; (2) conduct both acute toxicity tests via water exposure and long-term sediment toxicity tests for the selected model substances to generate data for comparative discussion; (3) assess correlations among acute toxicity data of the organisms exposed via water-only and correlations among sediment toxicity data of the two endobenthic invertebrates for the eight tested chemicals; (4) assess possible forecasting for sediment toxicity from acute toxicity (via water-only exposure) and (5) assess exposure effects to determine the main exposure route. Acute toxicity data of the eight tested chemical.

Book Synopsis Sediment Quality Assessment by : Graeme Batley
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.
Book Synopsis Comparison of Porewater and Elutriate Bivalve Larval Development Toxicity Testing in a Sediment Quality Triad Framework by : Blair Gordon McDonald
Download or read book Comparison of Porewater and Elutriate Bivalve Larval Development Toxicity Testing in a Sediment Quality Triad Framework written by Blair Gordon McDonald and published by . This book was released on 2003 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The magnitude and extent of contaminated marine sediment are frequently assessed using a Sediment Quality Triad framework involving multiple toxicity tests using a variety of species, toxicological endpoints and exposure systems. Data are integrated into an overall assessment of sediment quality using a weight of evidence approach. Guidance on the selection of appropriate toxicity tests recommends a wide range of organism type, life-cycle, exposure route, and feeding type be included - porewater bivalve larval development tests increases the number of exposure routes under consideration. Interpretation of porewater toxicity data are subject to limitations, in part, related to the extensive chemical manipulations associated with the extraction of in situ anoxic porewater and the subsequent aeration required for the laboratory-based toxicity test. The ability of the porewater-only test to represent ecologically relevant adverse effects in the field appears minimal. Results from concurrent porewater and elutriate toxicity testing using newly fertilized larvae of the bivalve, Mytilus galloprovincialis are provided to illustrate these problems. Porewater samples were consistently more toxic than the corresponding elutriate sample, and ammonia, a common confounding factor in sediment toxicology, was identified as the most likely toxic agent for the majority of samples. Porewater toxicity testing using M. galloprovincialis is therefore not recommended as a routine element of the sediment quality triad unless additional chemistry (samples used for testing as well as in situ) are available to facilitate an appropriate interpretation of the resulting toxicity data.

Book Synopsis Ecological Toxicity Testing by : John Cairns, Jr.
Download or read book Ecological Toxicity Testing written by John Cairns, Jr. and published by CRC Press. This book was released on 1994-12-27 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ecological Toxicity Testing provides a critical comparison of toxicity tests at different levels of biological organization from cells to landscapes. While ecological toxicity tests can be designed at any of the many levels of complexity and on spatial scales ranging from square millimeters to square kilometers, the uses to which this information can be put often differs with scale. In the past decade, tests at all levels have been refined and subjected to critical evaluations of their predictive accuracy. This text/reference includes evaluations of toxicity test systems at various scales and complexities by expert practitioners. It also offers broader analyses of the effects of scale on endpoint selection, test design and analyses, and chemical sensitivity.

This book was released on 2012-12-06 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: The determination of the hazards resulting from the accidental or deli berate contamination of terrestrial and aquatic environments is in most countries still lirnited to the detection and quantification of the suspected pollutants by chemical analyses. Such an approach is unfortunately hampered by the following constraints : the costs as weil as the technical difficulties of analyzing every individual chemical which may be present in the sampies, and the difficulty of assessing the hazards and risks of environmental contaminations from a set of chemical data. During the last decades the scientific and regulatory community has gradually realized that biological methodologies have to be taken into consideration for an ecologically meaningful assessment of the toxicological hazards of contaminants. Effect evaluations obtained with biological techniques indeed integrate the impact of all the contaminants to which living biota are exposed. Bioassays with selected test species representative for the biological commumtles of the environments under consideration, are now applied more or less regularly to determine toxic and genotoxic effects. Taking into account the species specific and chemical specific character of toxicity to biota, the necessity of a «battery of tests» approach with species of different trophic levels is currently also generally accepted and implemented. It is dear that a balanced partnership between chemical, biological, toxicological and microbiological analyses is always the best strategy for generating the broadest information base on environmental hazards.
