"Heavy Metals: Problems and Solutions" is divided into three sections dealing with basic geochemical processes, remediation and case studies. The basic geochemical processes are discussed with respect to mobility in the environment and impact as well as methods to derive guidelines for heavy metals. Remediation focuses on currently available methods to treat contaminated sediments and soils. In addition, it considers the concept of geochemical engineering for remediation of large areas contaminated by metals. A number of case studies of polluted sediments and soils and their environmental impact highlight the principles discussed in the first two sections.
Providing comprehensive discussions of the physical and chemical properties, manufacture, and industrial uses of biosurfactants, this reference offers first-hand accounts of biosurfactant research of leading biotechnology laboratories. It introduces promising possible uses of biosurfactants in medicine, in environmental control, and for marine
Environmental decisions must satisfy a multitude of objectives and the matching of a plan, policy or project to such objectives is a matter of both facts and value judgements. Value Functions for Environmental Management provides a systematic approach to the structuring and measurement of value judgements, showing how they drive the decision process and how to make them transparent and effective in support of complex decisions. The value functions that the book describes provide a scheme for the exploration of human values and a tool for transforming them into an analytical model. A clear statement can then be made of the degree to which a decision has achieved its objectives, and how confli...
Ein zeitgemäßer Beitrag zum Schutz unserer wertvollen Grundwasservorräte! In drei Teilen beschreibt dieser Band alle Aspekte der Mikrobiologie und Geochemie des Grundwassers. Teil 1 ist einem allgemeinen Überblick über die vorhandenen Mikroorganismen (Arten, Wachstum, Metabolismus, Genetik, Ökologie) gewidmet. Teil 2 befaßt sich mit Verteilung dieser Organismen im Grundwasser, Probennahme und geochemischen Modellen. Im Mittelpunkt des 3. Teils stehen mikrobiologische Prozesse in wasserführenden Schichten, die mit Chemikalien verunreinigt wurden. (10/00)
Increasing awareness of the irreversible and long-lasting impacts of deterioration and pollution of soils and sediments has had an important influence on environmental policies and research in the last decade. The complexity of the soil and sediment systems and its processes cannot be tackled properly unless scientists from different disciplines work together. With this in mind, a number of multidisciplinary soil research programmes have been started in various European countries. They involve different disciplinary approaches and they aim at different fields of application: agriculture, land use and town and country planning, drinking water supply, nature management. The results that are now appearing need to be integrated in a scientifically sound and useful way. The first European Conference on Integrated Research for Soil and Sediment Protection and Remediation was intended to foster this. The volume contains the edited and selected proceedings of this Conference.
Bioremediation focuses on the application of practical, state-of-the-art technology used for full-scale site remediation over a wide range of environmental settings. The book includes an up-to-date overview of the environmental regulations critical to the success of biological treatment in the field as well as the market opportunities presented for implementing bioremediation based on those regulations. Crucial factors to consider prior to selecting bioremediation for site remediation are also discussed.
Metal Speciation and Contamination of Soil provides a thorough overview of the biogeochemical processes governing the behavior, transport, and bioavailability of heavy metals in contaminated soils and suggests alternative approaches for effective remediation. This important new book contains contributions from experts in various disciplines who explore the issues from theoretical, experimental, and pragmatic perspectives. Topics include redox chemistry, kinetics of metal reactions, spectroscopic characterization of metal ion reactions at surface, modeling hydrologic transport phenomena and colloid-associated transport of metals through the soil profile to ground water, and remediation alternatives.
Sustainable development and pollution control are the key factors in the development of strategies for the solution of environmental problems. This book offers an integrated treatment of all aspects of environmental protection and remediation. The presentation encompasses physical and chemical fundamentals, technological approaches as well as ecological, economic, and ethical aspects. The discussion of regulatory issues includes a comparison of environmental legislation in the US, Japan and Europe. The book addresses students as a comprehensive text and serves as a handy reference for environmental professionals in industry, consulting services, administration, and environmental agencies and associations.
