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.

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.

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.

After fifteen years and three editions, Introduction to Environmental Toxicology: Molecular Substructures to Ecological Landscapes has become a standard that defines the field of environmental toxicology, and the fourth edition is no exception. The authors take an integrated approach to environmental toxicology that emphasizes scale and context as important factors in understanding effects and management options. New in the Fourth Edition: New author, Dr. Ruth M. Sofield 8-page color insert New chapter on fate and transport of contaminants Emphasis on the use of all types of models in understanding how nature works Revised sections on synergy and atrazine toxicity Updated coverage of the analysis of impacts to populations, communities and ecosystems Enlarged risk assessment chapter with an in-depth description of a regional scale risk assessment This edition benefits from the insight of a new author, Dr. Ruth M. Sofield, who prepared the new chapter on the fate and transport of contaminants. The relationship between structure and toxicological properties has been a major theme of this book since its inception and this new chapter expands this fundamental concept to include fate and transport. In the early chapters the use of models in science is discussed and this theme carries throughout the rest of the book. So much has changed in the fifteen years since the publication of the first edition. The mid-1990s seem so long ago, when our understanding of environmental toxicology was very basic. Ecological risk assessment was in its very early stages and the consideration of the effects of toxicants on landscapes was only beginning. Computation was still hard, genes stayed put, and it was only becoming recognized that xenobiotics could have hormonal effects — developments that are taken for granted in this edition. Written by authors who teach this subject, a feature that is reflected in their straightforward style, the book provides a foundation for understanding environmental toxicology and its application.

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.
