Book Description
This is a unique compilation on the use of leaching/extraction methods in different fields. The use of leaching test methods is increasing in various areas including: waste treatment and disposal; incineration of waste; soil clean-up and reuse of cleaned soil; sludge treatment. This has led to (and may increasingly lead to) the development of a large number of very similar tests in these different fields. However, these developments are taking place with no clear understanding of their mutual relationships. In view of these developments, efforts are needed to harmonize the leaching procedures that could be adapted for different matrices, as well as validate the use of existing tests in other fields. The development of a wide variety of leaching/extraction tests for different matrices is undesirable from a regulatory point of view and undesirable for industry. Clarity in testing is crucial in producer-consumer relations. This collective document will assist in improving the understanding of leaching from a variety of sources and will, where appropriate, help to bring together the approaches used in different technical fields and in different countries.

Book Description
This book covers a broad group of wastes, from biowaste to hazardous waste, but primarily the largest (by mass and volume) group of wastes that are not hazardous, but also are not inert, and are problematic for three major reasons: (1) they are difficult to manage because of their volume: usually they are used in civil engineering as a common fill etc., where they are exposed to environmental conditions almost the same way as at disposal sites; (2) they are not geochemically stable and in the different periods of environmental exposure undergo transformations that might add hazardous properties to the material that are not displayed when it is freshly generated; (3) many designers and researchers in different countries involved in waste management are often not aware of time-delayed adverse environmental impact of some large-volume waste, and also do not consider some positive properties that may extend the area of their environmentally beneficial application.

Book Description
This book provides a unique source of reference on the chemical analysis of potentially contaminated land. It assists in specifying appropriate analyses, relevant strategies for carrying out analyses, and methods of interpreting results within the new risk-based legislative framework for contaminated land. It addresses all aspects of the analysis, from delivery of the samples to the laboratory to the presentation of the results to the clients. Emphasis is placed on concentrated, tabular data, wherever possible. Problems of analysis are highlighted and solutions are proposed. Asbestos is covered in detail in the chapter on inorganic parameters, and a chapter is included on the new techniques of ecotoxicity measurement. Directed equally at the analytical chemist and the environmental scientist or engineer responsible for commissioning analyses of potentially contaminated soil or water samples, the book is written in a way that will prove helpful to both new and experienced practitioners. As such, it is one of the first volumes to bridge the gap between the customer and the supplier.

Book Description
In 2000, the leaders of member states of the United Nations adopted the Millennium Declaration, which set out a series of clear commitments, goals and targets to achieve Human Development. These ambitious goals were subsequently refined into eight Millennium Development Goals (MDGs), designed to provide a framework for accountability, donor coordination and resource mobilization. The MDGs are: Eradicate extreme poverty and hunger; achieve universal primary education; promote gender equality and empower women; reduce child mortality; improve maternal health; combat HIV/AIDS, malaria and other diseases; ensure environmental sustainability; and develop a global partnership for development. The first seven of these Goals are concerned with outcomes, identifying the progress towards certain standards of human well-being and decent living which should be achieved globally and nationally by 2015. The eighth Goal is concerned with relationships, identifying various aspects of a “global partnership for development” which must be forged to support the realization of these poverty reduction, human development and environmental sustainability standards. The MDGs provide opportunities to start working from real-life development problems. Addressing these problems requires multidisciplinary approaches that combine the natural sciences, the life sciences and technical approaches with social-science approaches. The challenge is to integrate social, economic, political and institutional concerns into research strategy. To be able to achieve this, there is a need to establish a linking pin between research, policy and practice in Nigeria. The aim of such a linking pin would be to synthesize research outcomes on specific MDGrelated topics and to translate these into implications for policy – and decision – making through easily accessible gathering where individual stakeholders can air their views. The articles contained in this book address research outcomes from stakeholders (Sociologists, Economists, Agronomists, Agricultural Engineers, Civil Engineers, Environmental Scientists and Engineers, Geographers, Geologists, Microbiologists, Medical Practitioners, Policy Makers, Educationists, etc.) to confirm achievement of Millennium Development Goals in Nigeria and other neighboring countries.

Book Description
The chapters of this book were originally presented at the Fourth International Conference on the Biogeochemistry of Trace Elements, in June 1997 at Berkeley, California. The results of that symposium are now available to assist both specialists and those concerned with broader environmental issues. The first four chapters of Fate and Transport of Heavy Metals in the Vadose Zone are devoted to sorption-desorption processes. Subjects include the kinetics of trace metal sorption-desorption, adsorption of nickel and their isotherms, cadmium reactions, and retention mechanisms of both linear and nonlinear types. The next three sections describe complexation and speciation processes. The authors consider the effect of humic and fulvic acids, the binding of copper with organic matter, and the rate of dissolved selenium. Chapters eight through eleven scrutinize the bioavailability and retention of heavy metals and their mobility in the vadose zone. Twelve details plant-available concentration levels for heavy metals in the vadose zone. The last section relates case studies that are relevant to environmental affairs. Features

Book Description
This book presents a comprehensive and detailed description of remediation techniques for metal-contaminated soils derived from both natural processes and anthropogenic activities. Using a methodical, step-by-step presentation, the book starts by overviewing the origin of toxicants and the correlated comparative extent of contamination to the environment. The legal provisions as proposed or applied in different countries are then discussed to explain the global regulatory situation regarding soil contamination and the extent of consequent concern. The core part of this publication describes the major techniques for in situ or ex situ treatment of the contaminated soil to meet the regulatory limits. Finally, risk evaluation is incorporated, giving special attention to possible impacts during or after implementation of the remediation strategies. The intrusion of metals in soils mostly occurs from various anthropogenic activities, e.g., agricultural practices, industrial activities, and municipal waste disposal. The volumes of metal-contaminated soil are becoming greater than before and are ever-increasing due to rapid urbanization, intensified industrialization, and/or population booms in certain parts of the world. Hence, the options previously proposed, such as isolation of the contaminated site or movement of the contaminated mass to a secure disposal site after excavation, are becoming unsuitable from the economic point of view, and instead, decontamination alternatives are preferred. This book will help readers such as scientists and regulators to understand the details of the remediation techniques available to deal with the soils contaminated by toxic metals.

Book Description
This multidisciplinary book covers a wide range of topics addressing critical challenges for advancing the understanding and management of shale oil and shale gas resources. Both fundamental and practical issues are considered. By covering a variety of technical topics, we aim to contribute to building a more integrated perspective to meet major challenges faced by shale resources. Combining complementary techniques and examining multiple sources of data serve to advance our current knowledge about these unconventional reservoirs. The book is a result of interdisciplinary and collaborative work. The content includes contributions authored by active scientists with ample expertise in their fields. Each article was carefully peer-reviewed by researchers, and the editorial process was performed by an experienced team of Senior Editors, Guest Editors, Topic Editors, and Editorial Board Members. The first part is devoted to fundamental topics, mostly investigated on the laboratory scale. The second part elaborates on larger scales (at near-wellbore and field scales). Finally, two related technologies, which could be relevant for shale plays applications, are presented. With this Special Issue, we provide a channel for sharing information and lessons learned collected from different plays and from different disciplines.
