Book Synopsis Guidance Document on Measurement of Toxicity Test Precision Using Control Sediments Spiked with a Reference Toxicant by : Roman Lanno
Download or read book Guidance Document on Measurement of Toxicity Test Precision Using Control Sediments Spiked with a Reference Toxicant written by Roman Lanno and published by . This book was released on 1995 with total page 82 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides guidance and recommendations for selection of a reference toxicant, spiking procedures, and use of control sediments for assessing changes in sensitivity of test organisms to toxicants and measuring precision of both intra- and inter-laboratory spiked-sediment toxicity tests. Four potential reference toxicants (cadmium, copper, pentachlorophenate, and fluoranthene) were considered for selection since they were the only chemicals with published information regarding sediment spiking and use in sediment toxicity tests. The recommendations on the use of these toxicants in tests using either freshwater or marine sediment reflect the information currently available. Instructions are included for the selection of control sediments for spiking, selection and use of test organisms, acquisition and handling of chemicals, conducting reference toxicant tests, establishing and updating warning charts, record keeping, and data reporting. Key areas requiring further research are also identified. The appendices include a summary of current research on formulated sediments, a list of information typically provided in a material safety data sheet, and graphs showing the fate of copper and cadmium added to natural seawater.

Download or read book Dredging and Marine Environment written by Claude Alzieu and published by Editions Quae. This book was released on 2005 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: L'accès des navires aux zones portuaires est assuré par le dragage de quantités importantes de sédiments. Les matériaux dragués ne peuvent être immergés que s'ils présentent toutes les garanties d'innocuité pour le milieu marin. Après un rappel sur la géochimie et la toxicité des différents contaminants qui sont adsorbés sur les sédiments, le présent ouvrage propose une approche globale de l'évaluation des risques environnementaux liés aux immersions. Les méthodes de caractérisation des risques à partir de l'analyse chimique (Géodrisk) et de tests de toxicité sélectionnés, de bioévaluation de la qualité des sédiments par la définition d'un Indice d'évaluation de l'endofaune côtière (I2EC) et de biomonitoring actif des zones d'immersion, sont décrites de manière détaillée. Cette démarche ascendante et itérative, appliquée au contexte réglementaire français, permet de satisfaire aux recommandations des conventions internationales et en particulier aux lignes directrices OSPAR.

Book Synopsis Biological Test Method by : Canada. Environment Canada
Download or read book Biological Test Method written by Canada. Environment Canada and published by Canadian Government Publishing. This book was released on 1992 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Methods recommended by Environment Canada for performing 10-day tests for sediment toxicity, using one or more of the following species of marine or estuarine sediment-burrowing amphipods, are described in this report: Amphiporeia virginiana, Corophium colutator, Eohaustorius estuarius, Eohaustorius washingtonianus, Foxiphalus xiximeus, Leptocheirus pinguis, and Rhepoxynius abronius. The biological endpoint for the test is percent mortality at Day 10. Additional (sublethal) endpoints that measure the percentage of surviving amphipods that emerge from the sediment at Day 10 (i.e., avoidance response) and/or the ability of the amphipods to rebury when transferred to control sediment, can also be determined using this test. The test is performed in 1-L glass vessels, with 175 mL of solid-phase sediment and 759 mL of overlying seawater. General or universal conditions and procedures are outlined for preparing for and undertaking the test. Additional conditions and procedures are stipulated that are specific to the intended use of the test (e.g., assessment of samples of field-collected sediment, sludge or other solid waste, or chemical introduced to sediment). Included are: instructions on collecting, identifying, and transporting test organisms; sorting and handling procedures; holding and acclimatization conditions; sample transport and storage; test facility requirements; procedures for preparing test sediments and test initiation; specified test conditions; appropriate observations and measurements, endpoints, methods of calculation; the use of reference toxicants, and test validation.
Book Synopsis Sediment Risk Management and Communication by : Damià Barceló
Download or read book Sediment Risk Management and Communication written by Damià Barceló and published by Elsevier. This book was released on 2007-03-12 with total page 293 pages. Available in PDF, EPUB and Kindle. Book excerpt: In dynamic river systems, effective and sustainable risk management of sediments, contaminants and their sources must be carried out on a river basin scale. A diversity of interests and risk perceptions, whether environmental, economical, or personal, as well as the broad variety of uses and functions of river systems can lead to conflicts and disagreements about how and where river systems should be managed. This requires a transparent methodology to assess environmental risks in the river basin, followed by a prioritisation of those sites where measures would yield the highest positive effect for the river basin and where financial resources could be allocated most efficiently. However, risk perceptions may only partially be influenced by scientific assessments of risk, and often also depend on a variety of factors such as personal experience and confidence in institutions. Risk managers must develop methods to balance technical and socioeconomic issues with the aim to reduce risks posed by sediments to environmental and economic resources to a level that is perceived as tolerable by society. Sediment Risk Management and Communication (Vol.3 in the SEDNET mini-series) is based on discussions that were held in the working group on "Risk Management and Communication" which was one of 4 working groups within the European Demand-Driven Sediment Research Network "SedNet". It aims to analyse the current situation in Europe with regard to sediment risk management issues, to draw conclusions from this analysis and to offer recommendations for sustainable risk management from basin to site-specific scale. This volume also available as part of a 4-volume set, ISBN 0444519599. Discount price for set purchase. A broad overview on sediment quality and impact assessment of pollutants Suitable for both newcomers to the field of sediment treatment and specialists alike Outlines practical examples of methods used in sediment quality analysis
