Book Description
Aldo Leopold, father of the "land ethic," once said, "The time has come for science to busy itself with the earth itself. The first step is to reconstruct a sample of what we had to begin with." The concept he expressedâ€"restorationâ€"is defined in this comprehensive new volume that examines the prospects for repairing the damage society has done to the nation's aquatic resources: lakes, rivers and streams, and wetlands. Restoration of Aquatic Ecosystems outlines a national strategy for aquatic restoration, with practical recommendations, and features case studies of aquatic restoration activities around the country. The committee examines: Key concepts and techniques used in restoration. Common factors in successful restoration efforts. Threats to the health of the nation's aquatic ecosystems. Approaches to evaluation before, during, and after a restoration project. The emerging specialties of restoration and landscape ecology.

Book Description
Freshwater field tests are an integral part of the process of hazard assessment of pesticides and other chemicals in the environment. This book brings together international experts on microcosms and mesocosms for a critical appraisal of theory and practice on the subject of freshwater field tests for hazard assessment. It is an authoritative and comprehensive summary of knowledge about freshwater field tests, with particular emphasis on their optimization for scientific and regulatory purposes. This valuable reference covers both lotic and lentic outdoor systems and addresses the choice of endpoints and test methodology. Instructive case histories show how to extrapolate test results to the real world.

Book Description
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.

Book Description
Hazard assessment of a compound (xenobiotic) discharged to the aquatic environment requires data on both exposure and effects to various components of the ecosystem. The multitude of ecological gradients in the Baltic Sea is used as a background example for discussing the complexity of the issue and the need for new approaches. Therefore, this book attempts to go beyond the simplistic, standardized short-term laboratory tests traditionally used as a basis for hazard assessment of chemicals, and gives strong emphasis to the interpretation of ecotoxicological data in their real, ecological context, pointing out the need to consider the natural mortality distribution of the population under study, the role of keystone species and of species with broad ecological niches versus those with narrow, specialized niches.

Book Description
A Special Publication of the Society of Environmental Toxicology and Chemistry (SETAC) Aquatic Mesocosm Studies in Ecological Risk Assessment discusses the methods currently used for conducting simulated field studies and provides a series of case histories in which mesocosm type studies have been used to assess the impact of pesticides on aquatic ecosystems. Specific chapters address the dosing and exposure components of such studies and how they influence experimental design. Advantages and disadvantages of various statistical designs are addressed in detail. Regulatory aspects of the design and interpretation of these studies are also covered. The book will be a superb reference for aquatic biologists, ecologists, toxicologists, environmental toxicologists, environmental chemists, and regulatory personnel.

Book Description
The Handbook of Ecotoxicology provides a readily accessible, yet critical collection of information on ecotoxicological testing. Now available in a single paperback volume, this handbook represents excellent value. Part A concentrates on techniques, especially those tests used for prediction. Thorough descriptions of the main tests are provided, followed by critical analyses in terms of ease of handling, repeatability and ecological relevance, and finally, an extensive bibliography citing key documents describing test methods and key papers evaluating them. Part B focuses on the toxicants themselves: summarising their ecological effects, describing ways of predicting effects from physico-chemical properties alone, and describing and discussing fate models. Now available as a single volume in paperback An invaluable reference resource

Book Description
Organic Chemicals in the Aquatic Environment draws from the author's experience with a variety of problems dealing with the fate, distribution, and toxicity of organic compounds in the aquatic environment. It discusses the basic issues of chemical analysis, distribution, persistence, and ecotoxicology, with an emphasis on microbial reactions. The necessary input and the difficulties of achieving a rigorous synthesis of the various elements are illustrated with specific examples. The book includes a wide range of structurally diverse compounds as illustration and presents a mechanistic approach to biodegradation and biotransformation. The final chapter addresses the issue of environmental hazard assessment and constructs a strategy for carrying it out.
