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.

Little attention has been paid to the techniques for aquatic sediment sampling in the scientific literature dealing with environmental issues. With increasing interest in aquatic sediments as a sink source of contaminants in aquatic ecosystems, it has been recognized that sediment sampling is a complex and poorly documented discipline. No standardized methods exist to preserve the integrity of sediment and, particularly, sediment pore water, during sampling for different analyses and biological testing for assessment of sediment quality. A practical guide presenting the various methods available would prove extremely valuable. This is that guide. The book begins with a description of the objectives of sediment sampling for different purposes and planning of sampling programs. Most commonly used and readily available samplers and sampling techniques are explained for routine monitoring of sediment contamination and studies of sediment quality. Sample handling, transport, and storage are outlined relevant to the subsequent use of the collected sediments in physico-chemical analysis and biological testing. Measurements and notes of observations in the field during collection of sediments are described. Methods and equipment for collection of sediment pore water are detailed, and the efficiency, cost, and safety involved in sediment sampling are considered. The Manual of Aquatic Sediment Sampling contains examples, figures, and tables to enhance the reader's understanding of the material and of the importance of choosing proper techniques in sediment sampling programs. For each topic, recent citations are included from specialized literature. The Manual of Aquatic Sediment Sampling contains many examples, figures, and tables which will help the reader to understand the importance of choosing proper techniques in sediment sampling programs, and will provide a guide to preparation and execution of such programs.

Describes methods recommended for the selection of sampling stations within an environmental study site, and the collection, handling, storage, transportation, and manipulation of samples of whole sediments from marine, estuarine, and freshwater environments. Outlines general methods and procedures for two types of undertakings: monitoring and assessment studies, and studies specified in permit requirements for open-water disposal of dredged materials. Included in the general procedures are recommended methods of collection for test, control, and reference sediment, in-situ collection of pore water, sample handling, transportation, storage methods or conditions, and whole-sediment sample preparation for bioaccumulation tests, physicochemical characterisation, and/or toxicity testing. Methods are also recommended for the laboratory collection of pore water and elutriate from field-collected whole-sediment samples. Additional procedures or conditions specific to the various aquatic environments are also addressed.

Assessment of freshwater sediments can determine whether chemical concentrations are sufficient to cause adverse effects on aquatic organisms or organisms higher in the food chain, including humans. This book presents methods for assessing sediments and includes an integration of physical, chemical, and biological information. It examines the elements of quality assurance and control programs, considerations for the conduct of field surveys, screening-level analyses, chemical analyses, toxicity tests for assessing biological impacts, assessments of benthic invertebrate community structure, surveys of fish tumors and abnormalities, and data presentation and interpretation techniques.
