Past generations of industrial development and chemical production are still very much with us-through contaminants they've left in all phases of the ecosystem. Especially vulnerable to this damage: water. Professionals from various disciplines in environmental sciences are becoming increasingly involved in water quality issues. The Manual of Bioassessment of Aquatic Sediment Quality now provides the most current techniques and methods, in the laboratory and the field, to detect and evaluate aquatic contaminants. Designed to complement the analytical methods presented in the companion volume, Manual of Physico-Chemical Analysis of Aquatic Sediments, the Bioassessment edition offers a comprehensive review of chemical forms, encompassing different elements and compounds in sediments, along with evaluation of their availability to aquatic biota. A discussion about the use of reference materials in sediment analysis also accompanies a review of laboratory safety measures. While greater environmental conscientiousness has led to sustainable industrial development and the recycling of materials, there remains the "hidden need" to remediate contaminated water sources throughout the world-essential to the continued survival of all life. The Manual of Bioassessment of Aquatic Sediment Quality will help environmental professionals ensure the protection of life-supporting streams, lakes and oceans throughout the world.
Because water is one of the most important life-supporting media on the planet, the quality of aquatic ecosystems is of great interest to the entire world population. One of the factors that greatly affects water quality is the condition of the underlying sediment layer. The Manual of Physico-Chemical Analysis of Aquatic Sediments addresses the best methods for quantitative determination of chemical forms of different elements and compounds, bioassessment techniques, and determination of physical properties of sediments. Essential information for surveying, research, and monitoring of sediment contamination is covered. This manual will aid sediment biologists, geochemists, limnologists, regulatory program managers, environmental chemists and toxicologists and environmental consultants in preparing plans for proper remedial action.
In aquatic ecosystems, the oligochaetes are often a major component of the community. Their relevance in sediment quality assessment is largely related to their benthic and detritivorous life habit. In this book, we aim to present the state of the art of Pollution Biology using oligochaete worms in laboratory and field studies. Future research will require the combination of a variety of methodological approaches and the integration of the resulting information, avoiding fragmented and often conflicting visions of the relationships of the species with their environment. Current approaches to ecotoxicology and bioaccumulation using ecological risk assessment provide the opportunity to relate community studies with probability of effects. This book addresses three main themes: Ecological and Field Studies using the composition and structure of oligochaete communities, Toxicology and Laboratory Studies, and Bioaccumulation and Trophic Transfer Studies. Two appendices list values of toxicological parameters (LC50, EC50) and several bioaccumulation variables (bioaccumulation factors, biological half-life, toxicokinetic coefficients, and critical body residues) for different oligochaete species. Additional information is provided on Methodological Issues and on the Taxonomy of several oligochaete families, with information on the most recent taxonomic debates. Each chapter includes a critical view, based on the authors’ experience, of a number of current issues which have been raised in the literature.
This book contains 26 contributions dealing with the biology of aquatic oligochaetes and covers a wide range of topics including taxonomy, morphology, ultrastructure, embryology, reproduction, feeding biology, ecotoxicity, community studies, and species distribution. Descriptions of new taxa in tropical areas, including Amazonian forest soils, as well as overviews on the biodiversity of aquatic oligochaetes in Australia and European groundwaters, are presented. New morphological characteristics in both marine and freshwater species are described and interpreted. Laboratory studies contribute to the knowledge of oligochaete feeding biology and reproduction. The use of aquatic oligochaetes in ecological risk assessment is analysed in detail, and standardised experimental designs for studies on bioaccumulation and pollutant transfer by food are included. Finally, a number of papers present the effects of oliogochaetes on the performance of an activated sludge plant, and multivariate approaches to the spatial and/or temporal distribution and composition of oligochaete communities in many different areas of the world, from the scale of a river to the scale of the microhabitat. The broad scope of this volume is a reflection of recent rends, not only in oligochaete research, but also in general applied biological studies.

The purpose of this book is to help engineers and scientists better understand contaminated sediment sites and identify and design remedial approaches that are more efficient and effective. Contaminated sediment management is a difficult and costly exercise that is rarely addressed with easily identified and implemented remedies. It is hoped that this book can help identify and implement management approaches that provide an optimal, if not entirely satisfactory, solution to sediment contaminant problems.​
This Test Guideline describes a method to assess bioaccumulation of sediment-associated chemicals in endobenthic oligochaetes worms. It applies to stable, neutral organic chemicals having log Kow values between 3.0 and 6.0, superlipophilic ...
A wide-ranging compilation of techniques, Extrapolation Practice for Ecotoxicological Effect Characterization of Chemicals describes methods of extrapolation in the framework of ecological risk assessment. The book, informally known as EXPECT, identifies data needs and situations where these extrapolations can be most usefully applied, makin
The only source that focuses exclusively on engineering and technology, this important guide maps the dynamic and changing field of information sources published for engineers in recent years. Lord highlights basic perspectives, access tools, and English-language resources—directories, encyclopedias, yearbooks, dictionaries, databases, indexes, libraries, buyer's guides, Internet resources, and more. Substantial emphasis is placed on digital resources. The author also discusses how engineers and scientists use information, the culture and generation of scientific information, different types of engineering information, and the tools and resources you need to locate and access that material. Other sections describe regulations, standards and specifications, government resources, professional and trade associations, and education and career resources. Engineers, scientists, librarians, and other information professionals working with engineering and technology information will welcome this research
