2 In China, there are more than 2,759 lakes with surface area greater than 1km , and 2 the total lake area is 91,019km . One-third of these lakes are freshwater lakes, and the majority are situated in the middle and lower reaches of the Changjiang River or in eastern China’s coastal areas. These lakes function as drinking water supplies, ood control systems, aquaculture and tourism resources, navigation channels, etc. Recently, many shallow lakes in China have been subject to rapid eutrophication and suffer from algal blooms. This issue has resulted in a shortage of drinking water and in degradation of their ecosystems. The control of eutrophication of shallow lakes is one of the main issues with which the local people and Chinese governments are concerned today. Lake Taihu is the third largest freshwater lake in China, with an area of about 2 2338km and a mean depth of 1. 9m, a typical shallow lake located in the delta of Changjiang River, the most industrialized and urbanized area in China. Its main function is supplying drinking water for the surrounding cities, such as Wuxi, Suzhou, and Shanghai, but tourism, aquaculture, sheries, and navigation are imp- tant as well. However, with economic development and increased population in the lake basin, Lake Taihu has suffered increasingly from serious eutrophication. The environmental issue of Lake Taihu is now a very common one, as most lakes from eastern China are confronted with it.

Stability of underground excavations is of great importance to an operating mine because it ensures the safety of the working people and operating equipment, and successful ore production. Due to the complex geological conditions and mine constructions, and variability and uncertainty in estimating rock mass mechanical properties, the assessment of rock mass stability for an underground mine is extremely challenging and difficult. Tackling of this difficult problem is not covered in detail in any of the textbooks currently available in the rock mechanics literature. This monograph aims to cover this gap in the rock mechanics and rock engineering field. This monograph provides detailed procedures for the stability assessment and support design for an underground mine case study. It covers the background of the mine site including the monitored deformation data, the state-of-art methodologies for the stability analysis of rock masses around underground excavations, performed laboratory tests, estimation of the rock mass properties, a brief theory and background of the 3-D Distinct Element Code (3DEC), and numerical modeling of underground rock mass stability including investigation of the effectiveness of rock supports. The monograph is an excellent reference for the senior undergraduates, graduate students, researchers and practitioners who work in the Underground Rock Mechanics and Rock Engineering area in the Mining Engineering, Civil Geotechnical Engineering and DEM (Distinct Element Method) Numerical modeling.

Reviews of Environmental Contamination and Toxicology attempts to provide concise, critical reviews of timely advances, philosophy and significant areas of accomplished or needed endeavor in the total field of xenobiotics, in any segment of the environment, as well as toxicological implications.

The population of cities around the world is growing at an alarming rate, and as a result the landscapes of most cities are going through enormous changes. In particular, fertile agricultural lands at the periphery of cities are being developed without consideration of holistic planning. As such, peri-urban areas, zones of transition from rural to urban land uses located between the outer limits of the urban and the rural environment are experiencing significant losses of agricultural land, increased runoff, and water quality degradation. Concurrently, the demands for water, food and energy are increasing within cities, and unless a balance is struck the liveability of these cities will soon be compromised. The current water and land use changes have serious consequences on lifestyle, environment, health and overall well-being of urban communities. This book therefore helps readers to understand the current issues and challenges and examines suitable strategies and practices to cope with current and future pressures of urbanisation and peri-urban land-use changes. The book examines a number of critical aspects in relation to the future of cities and peri-urban regions, including the suitability of policies and institutions to sustain cities into the future; impact of current trends in land use change, population increase and water demand; long term planning needs and approaches to ensure the secured future for generations ahead; and strategies to adapt the cities and land uses so that they remain viable and liveable. The readership of the book will include policy makers, urban planners, researchers, post-graduate students in urban planning and environmental and water resources management and managers in municipal councils.

By the end of the 1970s, contaminated sites had emerged as one of the most complex and urgent environmental issues affecting industrialized countries. The authors show that small and prosperous Switzerland is no exception to the pervasive problem of sites contamination, the legacy of past practices in waste management having left some 38,000 contaminated sites throughout the country. This book outlines the problem, offering evidence that open and polycentric environmental decision-making that includes civil society actors is valuable. They propose an understanding of environmental management of contaminated sites as a political process in which institutions frame interactions between strategic actors pursuing sometimes conflicting interests. In the opening chapter, the authors describe the influences of politics and the power relationships between actors involved in decision-making in contaminated sites management, which they term a "wicked problem." Chapter Two offers a theoretical framework for understanding institutions and the environmental management of contaminated sites. The next five chapters present a detailed case study on environmental management and contaminated sites in Switzerland, focused on the Bonfol Chemical Landfill. The study and analysis covers the establishment of the landfill under the first generation of environmental regulations, its closure and early remediation efforts, and the gambling on the remediation objectives, methods and funding in the first decade of the 21st Century. The concluding chapter discusses the question of whether the strength of environmental regulations, and the type of interactions between public, private, and civil society actors can explain the environmental choices in contaminated sites management. Drawing lessons from research, the authors debate the value of institutional flexibility for dealing with environmental issues such as contaminated sites.

Unlike most books on the subject, which offer only formulaic solutions to particular problems, Biological Treatment of Hazardous Wastes provides professionals with a conceptual framework within which to develop effective treatments tailored to any hazardous waste scenario they may encounter.

It is useful for students, researchers and engineers interested in membrane technologies for water reuse.

Environmental Epidemiology and Risk Assessment Tim Aldrich and Jack Griffith Environmental Epidemiology and Risk Assessment addresses the historical development of environmental epidemiology, touching on recent sensationalized environmental tragedies such as Love Canal and Chernobyl. Understanding the importance that public opinion plays in the success or failure of any important regulatory decision involving human studies, the authors elaborate the issue of communicating scientific findings to the public. The authors have employed the material in this book while teaching graduate courses in epidemiology and in the application of field studies for environmentally related risk assessment. Environmental Epidemiology and Risk Assessment is convenient for students to use in independent study, while instructors can use it as a reference and background source for classroom lectures. Each chapter contains a list of specific learning objectives, a detailed narrative including illustrations and case histories, and instructive assignments. The authors have also provided a list of recommended reading which complements the extensive bibliography and selected glossaries. This comprehensive text provides state-of-the-art instruction in the methodologic considerations with the design and conduct of environmental epidemiologic studies. The authors discuss disease mechanisms, the study of disease clusters, and surveillance techniques as these topics relate to environmental epidemiology. Environmental Epidemiology and Risk Assessment is a compilation of over thirty years of practical experience, university and public agency instruction, federal agency experiences, and community investigations, bringing together disparate scientific disciplines and offering the most comprehensive compendium of information to be found on the subject. Although this book serves as a reference text for trained epidemiologists, it places considerably more emphasis than is commonly found in epidemiologic texts on exposure monitoring, the use of biomarkers in epidemiologic studies, laboratory practices for environmental sampling, risk assessment, risk management, and environmental law. This "how to" book is an invaluable source for public health professionals with limited didactic training in epidemiology, but with interests and professional responsibilities that require a working understanding of the discipline.

Global society in the 21st century is facing challenges of improving the quality of air, water, soil and the environment and maintaining the ecological balance. Environmental pollution, thus, has become a major global concern. The modern growth of industrialization, urbanization, modern agricultural development and energy generation has resulted in the indiscriminate exploitation of natural resources for fulfilling human desires and needs, which has contributed in disturbing the ecological balance on which the quality of our environment depends. Human beings, in the truest sense, are the product of their environment. The man-environment relationship indicates that pollution and deterioration of the environment have a social origin. The modern technological advancements in chemical processes/operations have generated new products, resulting in new pollutants in such abundant levels that they are above the self-cleaning capacity of the environment. One of the major issues in recent times is the threat tohuman lives due to the progressive deterioration of the environment from various sources. The impact of the pollutants on the environment will be significant when the accumulated pollutants load will exceed the carrying capacity of the receiving environment. Sustainable development envisages the use of natural resources, such as forests, land, water and fisheries, in a sustainable manner without causing changes in our natural world. The Rio de Janeiro-Earth Summit, held in Brazil in 1992, focused on sustainable development to encourage respect and concern for the use of natural resources in a sustainable manner for the protection of the environment. This book will be beneficial as a source of educational material to post-graduate research scholars, teachers and industrial personnel for maintaining the balance in the use of natural sources for sustainable development.

Provides a comprehensive review and evaluation of waste containment technologies presently practiced in remediation applications. Covers the state-of-knowledge, construction and performance of the three main barrier types - vertical (walls), bottom (floors) and surface (caps).

The disposal of radioactive waste is a central issue in the future of nuclear power and poses considerable technical, political and social issues. This book addresses these topics in an integrated fashion using performance assessment of the disposal concept as a unifying theme. Subjects addressed include: regulatory criteria; waste types, sources and characteristics; man-made or "engineered" barriers; the selection and evaluation of geological disposal media; the use of underground research laboratories; the movement of radionuclides in the biosphere; repository performance assessment tools and approaches; addressing uncertainty and spatial variability; assessing information from natural systems; and looking at radioactive waste in relation to other wastes. The book provides an up-to-date picture of radioactive waste disposal issues and will be of interest to scientists, engineers and consultants working in the nuclear industry and the environmental field.

Contaminated sites and facilities may pose significant risks to the local populations because of the potential health and environmental effects associated with environmental contamination problems. Also affected are property owners and financiers due to reduced property values and possible financial liabilities. The effective management of contaminated sites is therefore an important environmental issue, requiring careful planning. This book addresses the issues relevant to the investigation and management of contaminated sites, emphasising problem diagnosis/characterisation and the development of site restoration/corrective action programs. The book focuses on methodologies that will allow scientifically justifiable/defensible, technically feasible, and economically viable corrective action assessment and response decisions to be made. This includes methods for developing effectual site restoration tasks, methods for evaluating the progress of corrective action programs, and the application of risk assessment methods as a decision-making tool. The goal of the book is to synthesise technically sound principles and techniques that can be applied globally to contaminated sites in different regions of the world.

Former industrial and urban land is increasingly being recycled, a practice which follows current political policy and is appropriate in the more heavily populated areas of Europe. The contamination which soils and water below such land may have suffered due to past industrial activities could pose future risks to new occupiers, or to the environment as a whole, and therefore it is important that an assessment of the risk is undertaken before such land is re-used. This volume has been written specifically to assist developers, consultants and planners who are involved in the reclamation of contaminated land in ensuring that such recycling does not expose the public or the wider environment to unacceptable risks. It provides a clear rationale for why such risk assessments are needed, outlines the current legislation regulating such activities, and indicates where the responsibilities lie for control of this development. Inevitably, the assessment approach of this book draws mainly on UK experiences and regulations but the methodology and basic principles provided are universal, and would be applicable when the safe recycling of contaminated land becomes a more important issue of development in other countries. The risk assessment approach advocated in the book will be valuable to many developers of contaminated land, since it is affordable and logical, and adequately diagnostic to identify sites where re-use will not be hazardous. The book describes a comprehensive range of risks which have been given due consideration as potential problems when former industrial land is reused, whilst also dispelling many of the vague and often unjustified concerns over land contamination.

This volume provides a comprehensive method for optimizing solid waste management practices and procedures at college and university campuses through the use of cluster analysis to combine Life Cycle Assessment and Analytical Hierarchy Process. Author Pezhman Taherei uses Malaysia's University of Malaya as a case study and model, and through this method was able to assess which combination of waste disposal, management, and recycling techniques generate the least environmental impact while retaining the maximum cost savings for the university. A method for analysis of solid waste composition is also proposed. Higher education institutes generate thousands of tons of solid waste per year. Comprehensive solid waste management programs, which take integrated solid waste management systems into consideration, are one of the greatest challenges to achieving campus sustainability. This system can serve as a guide and blueprint for other universities that are taking steps toward sustainability through improved solid waste management.

A visionary approach to eliminating industrial waste streams . . .
Here is a revolutionary solution to problems of industrial waste management by creating a system of environmentally balanced "industrial complexes" in which groups of industrial plants consume each other's waste--not only benefiting the environment, but also significantly reducing production costs.
Providing a clear introduction to this novel approach, Zero Pollution for Industry goes right to the heart of what environmental scientists, engineers, and administrators grapple with these days. It takes pollution prevention to the next level, past current reduction and reuse methods, and anticipates government regulations and societal trends that would factor environmental damage into production costs.
Also suitable as a companion volume for traditional industrial waste management texts at the graduate level, this thought-provoking book:
* Covers hot new material under consideration by professionals and policymakers, including the EPA and the NSF
* Discusses the basics of waste minimization and waste reuse as well as zero-pollution industrial complexing
* Presents detailed examples of how complexes in different industries could be structured
* Describes how to change industrial plant design practices to prevent pollution
* Teaches innovative production techniques for environmental protection to future engineers and administrators
* Shows how to plan for a pollution-free environment from an administrative point of view

Concise and uncluttered, this book is an eye-opener for anyone who would like to work toward a world free of industrial pollution in our fragile environment.

Life Cycle Assessment (LCA) has become the recognized instrument to assess the ecological burdens and human health impacts connected with the complete life cycle (creation, use, end-of-life) of products, processes and activities, enabling the assessor to model the entire system from which products are derived or in which processes and activities operate. This volume introduces the major new book series LCA Compendium - The Complete World of Life Cycle Assessment. In this volume, the main drivers in the development of LCA are explored. The volume also discusses strengths and limitations in LCA as well as challenges and gaps, thus offering an unbiased picture of the state-of-the-art and future of LCA.

This book provides an overview of state-of-the-art technologies for energy conversion from waste, as well as a much-needed guide to new and advanced strategies to increase Waste-to-Energy (WTE) plant efficiency. Beginning with an overview of municipal solid waste production and disposal, basic concepts related to Waste-To-Energy conversion processes are described, highlighting the most relevant aspects impacting the thermodynamic efficiency of WTE power plants. The pervasive influences of main steam cycle parameters and plant configurations on WTE efficiency are detailed and quantified. Advanced hybrid technology applications, particularly the Hybrid Combined Cycle concept, are examined in detail, including an illuminating compare-and-contrast study of two basic types of hybrid dual-fuel combined cycle arrangements: steam/water side integrated HCC and windbox repowering.

This thesis uses neoclassical growth models to evaluate what effect the limited availability of nonrenewable resources has on the economy's (world's) growth potential. Markus Merz concludes that recycling may serve as a mid-term solution to continued growth, but technological progress is needed in the long-run. The theoretical analysis starts with the well-known Dasgupta-Heal model and considers the effect of recycling and technological progress on the resource constraints; resource-augmenting and backstop technology are analyzed. After a thorough analysis of the models it is concluded that the ultimate solution to long-term economic growth is a backstop technology.

The target audience comprises primarily researchers and experts in the field but the book may also be beneficial for graduate students.

The construction industry is the largest single waste producing industry in the UK. Ensuring a supply chain of recycled materials affords many potential gains, achieved through: reducing the material volume transported to already over-burdened landfill sites, possible cost reductions to the contractor/client when considering the landfill tax saved and the potential for lower cost material replacements, a reduction in the environmental impact of quarrying and the saving of depleting natural material resources. Reuse of Materials and Byproducts in Construction: Waste Minimization and Recycling addresses use of waste and by products in the construction industry. An over view of new "green" design guides to encourage best practice will be examined and current legislation that channels on site practices, such as site waste management plans. Fundamental individual construction materials are discussed and the process of reforming by products and waste products into new construction materials is investigated, examining the material performance, energy required to convert waste into new products and viability of recycling. The main range of constructional materials will be examined. Aimed at postgraduate students, lecturers and researchers in construction and civil engineering, the book will also be of interest to professional design practices.

Putting forward an up-to-date waste-to-energy approach that combines experience, sophisticated modeling and technical-economic analysis, this book examines the current need for the maximum utilization of energy from waste and the associated environmental impacts. It outlines step-by-step procedures for a complex and original waste-to-energy approach from the idea to its industrial application. With waste incinerators and industrial plants producing large amounts of pollutants, municipalities as well as smaller decentralized operations are beginning to focus on waste research. The principal advantage of utilizing research findings is the ability to apply a complex approach "from idea to industrial implementation" with respect to the needs of the market established by thorough market analysis. This book builds on this concept with an original approach that takes into consideration geographical aspects, the specifics of regions/micro-regions and technological units and/or equipment. Key areas discussed and analyzed in the text include: strategic planning of energy-source locations according to the nature of the respective region or microregion; types and amounts of wastes; logistics etc. using original mathematical models; consideration of on-site processing of various types of waste, taking into account the character of the region (agricultural, industrial etc.); tailor-made technologies for energy recovery from various types of wastes; implementation of individual technologies with original elements; and support for environmental protection based on advanced flue gas (i.e. off-gas in the case of incineration) cleaning methods.
