Cementitious materials are being widely used as solidification/stabilisation and barrier materials for a variety of chemical and radioactive wastes, primarily due to their favourable retention properties for metals, radionuclides and other contaminants. The retention properties result from various mineral phases in hydrated cement that possess a high density and diversity of reactive sites for the fixation of contaminants through a variety of sorption and incorporation reactions. This book presents a state of the art review and critical evaluation of the type and magnitude of the various sorption and incorporation processes in hydrated cement systems for twenty-five elements relevant for a broad range of radioactive and industrial wastes. Effects of cement evolution or ageing on sorption/incorporation processes are explicitly evaluated and quantified. While the immobilisation of contaminants by mixing-in during hydration is not explicitly addressed, the underlying chemical processes are similar. A quantitative database on the solid/liquid distribution behaviour of radionuclides and other elements in hydrated cement systems is established on the basis of a consistent review and re-evaluation of literature data. In addition to recommended values, all underlying original experimental data and key experimental info rmation are provided, which allows users to trace the given recommendations or to develop their own set of key values. This database is closely tied to the safety analysis of near surface disposal of radioactive waste in Belgium. It focuses on radioelements, toxic stable elements and heavy metals, which makes it relevant for investigations involving the interaction of radioactive and conventional contaminants with cement-based barriers.

"Water and Health" strengthens the dynamic relationship between human health and water. The book has the potential to ignite our minds about several water-related diseases due to biological and chemical contamination, and to their high-end solutions. The contents are original, comprehensive and highly informative, and gradually take the reader around the component most important to his or her quality life, and not just existence. The book is set in social, scientific and economic dimensions, and is a must read for all those who cherish and celebrate human life and dignity.

This book, written by specialists from Canada, India, Italy, Palestine, Peru, Spain and the Netherlands, is a guide to establishing a city on a sustainable path. It addresses sustainable urban planning issues by breaking the city down to its components. A broad range of planning and sustainability considerations are discussed. Important concluding chapters provide a 'what to do and how to do it' practical roadmap for implementing a sustainability program.

This book focuses on the treatment and disposal technology used for solid waste in China, puts forward an optimal management scheme that takes into account the complete lifecycle, and introduces a new technical model that reflects the synergies of resource utilization and secondary pollution control. In addition, it provides a set of methods for professional on-site investigation, risk assessment, classification management and control to minimize the risk of groundwater contamination by solid waste at landfill. Given the extent and depth of knowledge and experience gathered in the book, it offers an important reference guide for government managers, environmental researchers, and all those involved in and concerned about solid waste disposal.

As prosperity levels rise, so too does the number of products and services being consumed. For policy makers in waste management facing a growing challenge, it is vital to understand the complex relationship between waste prevention policies and individual behaviour regarding waste generation. This book examines that interplay, taking a close look at the role of motivation, difficulties, values and constraints. The first part of the book explores the theoretical framework, policy, barriers and facilitators for waste prevention behaviour. The second part presents in-depth case studies from three cities (Sao Paulo, Sheffield and Tokyo) examining the contextual factors, behavioural variations among them and the role of motivation and constraints in their populations. The book provides a detailed picture of how waste prevention policies enter the private, domestic sphere, offering insights for generating behavioural change at the household level and thus moving larger communities towards sustainable waste management. The book will be of interest to students and researchers in the areas of environmental policy, management, sociology, psychology, geography, technology and waste studies.

This book proposes the use of coffee bagasse ash (CBA) waste as raw material to be used in ceramic formulations. The approach presented here is a solution to a current ambiental problem as CBA waste is discharged in high amounts in agriculture. The authors analyze the potencial of CBA as a material to substitute feldspar in tile production.

In India, you can still find the kabaadiwala, the rag-and-bone man. He wanders from house to house buying old newspapers, broken utensils, plastic bottles-anything for which he can get a little cash. This custom persists and recreates itself alongside the new economies and ecologies of consumer capitalism. Waste of a Nation offers an anthropological and historical account of India's complex relationship with garbage. Countries around the world struggle to achieve sustainable futures. Assa Doron and Robin Jeffrey argue that in India the removal of waste and efforts to reuse it also lay waste to the lives of human beings. At the bottom of the pyramid, people who work with waste are injured and stigmatized as they deal with sewage, toxic chemicals, and rotting garbage. Terrifying events, such as atmospheric pollution and childhood stunting, that touch even the wealthy and powerful may lead to substantial changes in practices and attitudes toward sanitation. And innovative technology along with more effective local government may bring about limited improvements. But if a clean new India is to emerge as a model for other parts of the world, a "binding morality" that reaches beyond the current environmental crisis will be required. Empathy for marginalized underclasses-Dalits, poor Muslims, landless migrants-who live, almost invisibly, amid waste produced predominantly for the comfort of the better-off will be the critical element in India's relationship with waste. Solutions will arise at the intersection of the traditional and the cutting edge, policy and practice, science and spirituality.

This brief gives a summary of the soluble bio-based substances (SBO) field. Urban bio-wastes of differing compositions and ageing conditions represent a promising source of soluble bio-based substances (SBO), potentially able to perform as chemical auxiliaries for applications in the chemical industry and in environmental remediation. In particular, SBO process development, characterization and scale-up is described and bioassay studies discussed. This brief also discusses the use of SBOs in wastewater treatment in the context of 'green' processes, their role as humic-like substances, and their potential use as photocatalysts for the degradation of pollutants present in aqueous solutions (dyes, pharmaceuticals, chlorophenols). Furthermore, the role of SBOs as complexing agents for iron ions in the implementation of the photo-Fenton processes under mild pH conditions is also explored. Finally, SBOs are showcased in their capacity as organic component alternatives to petrochemical products for the synthesis of new materials.

This book is not designed to be an exhaustive work on mine wastes. It aims to serve undergraduate students who wish to gain an overview and an understanding of wastes produced in the mineral industry. An introductory textbook addressing the science of such wastes is not available to students despite the importance of the mineral industry as a resource, wealth and job provider. Also, the growing imp- tance of the topics mine wastes, mine site pollution and mine site rehabilitation in universities, research organizations and industry requires a textbook suitable for undergraduate students. Until recently, undergraduate earth science courses tended to follow rather classical lines, focused on the teaching of palaeontology, cryst- lography, mineralogy, petrology, stratigraphy, sedimentology, structural geology, and ore deposit geology. However, today and in the future, earth science teachers and students also need to be familiar with other subject areas. In particular, earth science curriculums need to address land and water degradation as well as rehabili- tion issues. These topics are becoming more important to society, and an increasing number of earth science students are pursuing career paths in this sector. Mine site rehabilitation and mine waste science are examples of newly emerging disciplines. This book has arisen out of teaching mine waste science to undergraduate and graduate science students and the frustration at having no appropriate text which documents the scienti?c fundamentals of such wastes.

Systems for recycling and reusing precious metals and rare-earth minerals contained in used and discarded electronics are introduced in this book. The target audience is not academic researchers in the resource management and ecology fields but, rather, citizens who are concerned about our future environment and want to do something for the future.

This monograph on chemical treatment is one of a series of eight on innovative site and waste remediation technologies that are the culmination of a multi organization effort involving more than 100 experts over a two year period. It provides the experienced, practicing professional guidance on the application of innovative processes considered ready for full-scale application. Other monographs in this series address bioremediation, soil washing/soil flushing, solvent chemical extraction, stabilization/ solidifica tion, thermal desorption, thermal destruction, and vacuum vapor extraction. 7. 7 Chemical Treatment The term chemical treatment, as used in this monograph, refers to the use of reagents to destroy or chemically modify target contaminants by means other than pyrolysis or combustion. The monograph addresses processes that chemically treat contaminated soils, groundwaters, surface waters, and, to a limited extent, concentrated contaminants. Chemical treatment is a means of converting hazardous constituents into less environmentally ob jectionable forms in order to meet treatment objectives. This monograph addresses substitution, oxidation, and chemical precipi tation processes. It addresses processes within these classes that are suffi ciently advanced for full-scale application. There are a number of emerging technologies within these classes that are in the research or an early devel opment stage, not yet ready for full-scale application, that appear to be very promising technologically. Six such technologies are briefly addressed in Appendix A."

Among various industries releasing wastewater into the environment, printing, dyeing and textile industries are of great importance as they frequently contain high amounts of colorful compounds having high chemical and biological oxygen demands. Health related effects of colorants are extensively reported; which necessitates the seriousness of dye removal from water and wastewater. The utilization of advanced oxidation processes (AOPs) in dye degradation has gained considerable attention recently due to the release of high energetic radicals as oxidants that are capable of removing dye compounds. This Volume 1 presents versatile applications of AOPs in dye removal. Accordingly, processes such as Ozone-based AOPs, UV irradiation, catalytic AOPs, etc are discussed with the aim of dye removal under different operational parameters. The role of different nanoparticles is also investigated. By presenting the fundamentals of AOPs as well as recent advances, this book is useful for environmental engineers and chemists who are concerned with wastewater pollution and treatment.

Several long-term trends in technology evolution have become apparent since these symposia began in 1989. Earlier presenters more frequently discussed treatment methods involving harsh and extensive human intervention. As the symposia have continued, the number of presentations describing extremely harsh and expensive treatment technologies have gradually been supplanted by more subtle and gentler methods. Such methods include subsurface-engineered barriers, phytoremediation, and bioremediation. Nineteen manuscripts were selected for inclusion in this volume, based upon peer review, scientific merit, the editors' perceptions of lasting value or innovative features, and the general applicability of either the technology itself or the scientific methods and scholarly details provided by the authors. General topics include: soil treatment, groundwater treatment, and radioactive waste treatment.

During the past five years increased awareness of environmental contamination by nitroaromatic compounds has led to a dramatic increase in research on their biodegradation. The resulting discoveries have markedly extended our understanding of degradation mecha nisms and pathways in bacteria and fungi. Futhermore, this new basic knowledge promises the development of field applications of biodegradation systems for nitroaromatic com pounds. In May of 1994, an International Symposium on the Biodegradation of Nitro aromatic Compounds was held in Las Vegas, Nevada. This symposium brought together the scientists at the frontiers of research into the biodegradation of nitro aromatic compounds. The invited speakers were asked to review their area of expertise and write a critical, comprehensive synthesis of their work and related work by others. This book is the result of their efforts. The emphasis of the reviews is on basic research in biodegradation and biotransfor mation. Therefore, the reactions of nitroaromatic compounds in plants, animals, bacteria, fungi, soil, and even nonbiological systems are considered. The goal of the work is to provide the reader with an appreciation of the tremendous range of possibilities for metabolism of aromatic nitro compounds and the experimental approaches used to understand them. This volume should be of interest to biochemists, microbiologists, engineers, toxicologists, and anyone interested in the behavior of synthetic chemicals in the environment or in living systems. Furthermore, a variety of commercial applications can be envisioned for some of the reactions described here.

This volume, unlike the three preceding it, represents the collected papers from an experiment with an "electronic symposium." Co-participators in this symposium included The George Washington University, The Smithsonian Institution, Clark Atlanta University, the Agriculture Research Service of the United States Department of Agriculture, The University of Georgia, Morris Brown College, Spellman College, Morehouse College, North Carolina State University at Raleigh, The United States Food and Drug Administration, and the Forest Service of the United States Department of Agriculture among others. This unusual "electronic symposium" concept was developed by members of the Program, Planning and Organizing Committee as an alternative to the more costly convention-type symposium. As before, leading scientists in specific topic areas were invited to participate. Topic Session chairpersons were encouraged to arrange their own method of communication by telephone, electronic mail, or conference call, and report their findings back to the symposium center at The George Washington University. Additional papers were accepted from individuals and laboratories who are actively involved in relevant areas of research and study. Participation was also arranged for internationally established scientists. International authors are represented herein from Nigeria, Italy, Spain, Brazil and Argentina. Our goal was to present a research composite volume that reflected current developments, informed reviews, new and recently developing areas of the present state of knowledge as it relates to these proceeding topics. All of the reports included in this volume have undergone scientific, technical and editorial peer review.

This book has been a long time in preparation. Initially it grew out of our frustrating attempts over the past ten years to identify the filamentous bacteria seen in large numbers in most activated sludge plants, and the realization that we know very little about them and the other microbial populations in these systems. Unfortunately this book does not provide many answers to the problems these filamentous bacteria can cause, but we hope it might encourage microbiologists and engineers to communi cate more with each other and to spend some time trying to understand the tax onomy, ecology and physiology of activated sludge microbes. It is now very timely, for example, to try to provide these filamentous bacteria with proper taxonomically valid names and to determine their correct place in bacterial classifications. This book is not meant to compete directly with the books by Gray (1989, 1990) nor the excellent manual published by Jenkins and coworkers (1993b), which has been invaluable to us and others trying to identify filamentous bacteria. Wanner's book (1994a) also provides an excellent account of the problems of bulking and foaming caused by filamentous bacteria. These publications and others by Eikelboom's group have made an enormous contribution to the study of filamentous bacteria, and will con tinue to do so."

Over the past ten years, innovative technologies have shown that advanced oxidation processes are highly promising when applied to the remediation of polluted water or wastewater as they don t generate any sludge or solid material of hazardous nature.

"Advances in Ultrasound Technology for Environmental Remediation" reviews the fundamentals of ultrasound technology and the state of the art developments in ultrasound-based free radical generation in environmental remediation and pollution prevention. It also presents the challenges of introducing ultrasound technology into large-scale environmental remediation applications and examines the methods used to improve ultrasound technology. Indeed, ultrasonic systems are extremely sensitive and vulnerable to operational parameters which cannot be controlled without a good knowledge and understanding of physical and chemical phenomena.

"Advances in Ultrasound Technology for Environmental Remediation" features the theory and fundamentals of ultrasound technology and discusses its potential as an alternative method in environmental remediation."

This volume provides a current look at how development of intensive live stock production, particularly hogs, has affected human health with respect to zoonotic diseases primarily transmitted by food but also by water, air and oc cupational activity. While information presented focuses on the development of increasing livestock production in Canada, examples are given and compar isons are made with other countries (Denmark, Taiwan, the Netherlands and the United States) where the levels of livestock production are much more intense and where the industry is more mature. Canada is also searching for solutions to enable handling the growing volume of its livestock waste properly. Lessons learned from the experience of those who have gone before are invaluable and are drawn together in this volume to serve as useful guidance for others in plot ting the courses of action possible to avoid serious environmental setbacks and negative human health effects through foodborne illness. A significant portion of the text is devoted to a discussion of enteric illness in humans caused by zoonotic pathogens. The second chapter deals with sur vival of pathogens (which cause foodborne illness) in manure environments. An evaluation of the human health hazard likely to occur from the use of ma nure as fertilizer is important because of the recent trend toward an increase in foodborne illness from the consumption of minimally processed fruits and vegetables that may have been fertilized with animal-derived organic materials.

The research papers in this book present current knowledge of the sources, pathways, behavior, and effects of trace elements in soils, waters, plants, and animals. It is of interest to a variety of readers, including public health and environmental professionals, consultants, and academicians.

Twentyfour years have gone by since the publication of K. Lohner and H. MOiler's comprehen sive work "Gemischbildung und Verbrennung im Ottomotor" in 1967 1.1]. Naturally, the field of mixture formation and combustion in the spark-ignition engine has wit nessed great technological advances and many new findings in the intervening years, so that the time seemed ripe for presenting a summary of recent research and developments. There fore, I gladly took up the suggestion of the editors of this series of books, Professor Dr. H. List and Professor Dr. A. Pischinger, to write a book summarizing the present state of the art. A center of activity of the Institute of Internal-Combustion Engines and Automotive Engineering at the Vienna Technical University, which I am heading, is the field of mixture formation -there fore, many new results that have been achieved in this area in collaboration with the respective industry have been included in this volume. The basic principles of combustion are discussed only to that extent which seemed necessary for an understanding of the effects of mixture formation. The focal point of this volume is the mixture formation in spark-ignition engines, covering both the theory and actual design of the mixture formation units and appropriate intake manifolds. Also, the related measurement technology is explained in this work."
