The objective of this book is to summarize and critically assess the current status, development trends and needs of three basic defensive elements that safeguard the quality and environmental safety of soil and water/sediments: early warning monitoring, protection and remediation measures, with particular regard to the viability of methods and technologies, i.e. easiness-to-use, reliability, cost-effectiveness, high efficiency and non-destructive character of remediation that is of particular importance considering the scale of application. The primary aim of the book is to contribute to the improving maintenance of ecosystems, and specifically to summarize and add to information on how best to protect our soils and aquifers, prevent migration and mobilization of pollutants and how to enhance their degradation and/or immobilization. Mechanism of action is considered the first priority, but optimization of technical construction/application details are of no lesser importance. In the permeable reactive barriers, and other preventive/remediation measures, a number of novel integrated physicochemical and biochemical methods are presented. The remediation solutions for soil pollution are focused on non-destructive methods such as phyto- and ecoremediation that would preserve soil properties during and after decontamination. The contributors to the book are internationally recognized experts, which present both state-of-the art and novel approaches in the above fields that makes the book unique with respect to the scope.

Metal contamination of groundwater results from many human activities, including agriculture, mining, and the disposal of municipal waste and fly ash. Metals in Groundwater describes the transport of metals to groundwater from these and other sources. It also covers risk assessment of metals in groundwater, coupling of chemicals and hydrological models, and sorption of metals onto soils and clays. The speciation of metals is examined in detail. The book will interest researchers in environmental quality, mining, and agriculture; consultants; industry professionals; and personnel within regulatory agencies.

Over the past decade the sediments of many rivers, lakes, and estuaries have been contaminated by inorganic and organic materials. Contaminants from sediments, under certain conditions, can be released into overlying waters. Thus, sediments may be an important source of contaminants to waters in which littoral and atmospheric contaminants have been reduced or eliminated. Often found in aquatic sediments, metals are exposed to many reactions, such as sorption and precipitation, and are greatly influenced by the redox conditions in the sediment. The reactions - usually over a period of time - reflect biotic processing as well as chemical transformations. This book describes these important processes. Metal Contaminated Aquatic Sediments outlines advances in environmental chemistry, effective new modeling techniques, applications for biological treatment, and cycling and transport of trace metals in sedimentary environments. Each chapter contains a detailed reference section that draws upon a stunning array of sources. The book includes many figures and tables that illustrate the process under discussion. Features

Practical and provocative, Bioavailability reviews prevalent understanding of the physical-chemical-biological mechanisms that control the bioavailability of both organic and inorganic contaminants in aquatic environments.
Discusses the complex issues that surround many regulatory issues
Emphasizes the need to identify and control that portion of the total concentration that is biologically available and can cause adverse effects, i.e., "active"
Examines the influence of dynamic factors, such as pH, alkalinity, and light on these mechanisms
Addresses the subject of speciation for both organic and inorganic contaminants
