Based on a symposium sponsored by the Environmental Division of the American Chemical Society, Perchlorate in the Environment is the first comprehensive book to address perchlorate as a potable water contaminant. The two main topics are: analytical chemistry (focusing on ion chromatography and electrospray ionization mass spectrometry), and treatment or remediation. Also included are topics such as ion exchange, phytoremediation, bacterial reduction of perchlorate, bioreactors, and in situ bioremediation. To provide complete coverage, background chapters on fundamental chemistry, toxicology, and reulatory issues are also included. The authors are environmental consultants, government researchers, industry experts, and university professors from a wide array of disciplines.

Each year more than 200 million people are affected by floods, tropical storms, droughts, earthquakes, and also operational failures, wars, terrorism, vandalism, and accidents involving hazardous materials. These are part of the wide variety of events that cause death, injury, and significant economic losses for the countries affected.

In an environment where natural hazards are present, local actions are decisive in all stages of risk management: in the work of prevention and mitigation, in rehabilitation and reconstruction, and above all in emergency response and the provision of basic services to the affected population. Commitment to systematic vulnerability reduction is crucial to ensure the resilience of communities and populations to the impact of natural and manmade hazards.

Current challenges for the water and sanitation sector require an increase in sustainable access to water and sanitation services in residential areas, where natural hazards pose the greatest risk. In settlements located on unstable and risk-prone land there is growing environmental degradation coupled with extreme conditions of poverty that increase vulnerability. The development of local capacity and risk management play vital roles in obtaining sustainability of water and sanitation systems as well as for the communities themselves.

Unfortunately water may also represent a potential target for terrorist activity or war conflict and a deliberate contamination of water is a potential public health threat. An approach which considers the needs of communities and institutions is particularly important in urban areas affected by armed conflict. Risk management for large rehabilitation projects has to deal with major changes caused by conflict: damaged or destroyed infrastructure, increased population, corrupt or inefficient water utilities, and impoverished communities.

Water supply and sanitation are amongst the first considerations in disaster response. The greatest water-borne risk to health in most emergencies is the transmission of faecal pathogens, due to inadequate sanitation, hygiene and protection of water sources. However, some disasters, including those involving damage to chemical and nuclear industrial installations, or involving volcanic activity, may create acute problems from chemical or radiological water pollution. Sanitation includes safe excreta disposal, drainage of wastewater and rainwater, solid waste disposal and vector control.

This book is based on the discussions and papers prepared for the NATO Advanced Research Workshop that took place in Ohrid, Macedonia under the auspices of the NATO Security Through Science Programme and addressed problems Risk management of water supply and sanitation systems impaired by operational failures, natural disasters and war conflicts.

The main purpose of the workshop was to critically assess the existing knowledge on Risk management of water supply and sanitation systems, with respect to diverse conditions in participating countries, and promote close co-operation among scientists with different professional experience from different countries.

The ARW technical program comprised papers on 4 topics: (a) Vulnerability of Wastewater and Sanitation Systems, (b) Vulnerability of Drinking Water Systems, (c) Emergency response plans, and (d) Case studies from regions affected by Drinking Water System, Wastewater and Sanitation System failures.

Since the 1950s, the pines native to the San Bernardino Mountains in Southern California have shown symptoms of decline that have proven to result from exposure to ozone, a major plant-damaging gas in photochemical oxidant air pollution. Because of their proximity to major urban areas, the San Bernardino Mountains have served as a natural laboratory for studying effects of oxidant and acidic air pollution on a mixed-conifer forest. This volume presents a body of research conducted over more than thirty years, including an intensive interdisciplinary five-year study begun in 1991. Chapters include studies of the relationships of biogeography and climate to the region's air pollution, the chemical and physiological mechanisms of ozone injury, as well as the impacts of nitrogen-containing pollutants and natural stresses on polluted forests. The synthesis of such long-term studies provides insights into the combined influences of pollutants on ecosystem function in forested regions with Mediterranean-type climates.

This richly illustrated edition of an established classic deals with the chemistry and biology of soil nutrient availability. Provides information regarding the elements present in soils and the extent to which these elements can be used by plants in order to grow. Nutrient uptake by plant roots, rhizosphere microorganisms and application of the mechanistic uptake model as well as such elements as phosphorus, potassium and water are among the topics discussed.

If the political and social benchmarks of sustainability and sustainable development are to be met, ignoring the role of the humanities and social, cultural and ethical values is highly problematic. People's worldviews, beliefs and principles have an immediate impact on how they act and should be studied as cultural dimensions of sustainability. Collating contributions from internationally renowned theoreticians of culture and leading researchers working in the humanities and social sciences, this volume presents an in-depth, interdisciplinary discussion of the concept of cultural sustainability and the public visibility of such research. Beginning with a discussion of the concept of cultural sustainability, it goes on to explore its interaction with philosophy, theology, sociology, economics, arts and literature. In doing so, the book develops a much needed concept of 'culture' that can be adapted to various disciplines and applied to research on sustainability. Addressing an important gap in sustainability research, this book will be of great interest to academics and students of sustainability and sustainable development, as well as those studying sustainability within the humanities and social sciences, such as cultural studies, ethics, theology, sociology, literature and history.

In line with COP21 agreements, state-led climate change mitigation and adaptation actions are being undertaken to transition to carbon-neutral, green economies. However, the capacity of many countries for action is limited and may result in a 'boomerang effect', defined as the unintended negative consequences of such policies and programmes on local communities and their negative feedbacks on the state. To avoid this effect, there is a need to understand the policy drivers, decision-making processes, and impacts of such action, in order to determine the ways and means of minimizing negative effects and maximizing mutually beneficial policy outcomes. This book directly engages the policy debates surrounding water resources and climate actions through both theoretical and comparative case studies. It develops the 'boomerang effect' concept and sets it in relation to other conceptual tools for understanding the mixed outcomes of state-led climate change action, for example 'backdraft' effect and 'maldevelopment'. It also presents case studies illustrative of the consequences of ill-considered state-led policy in the water sector from around the world. These include Africa, China, South Asia, South America, the Middle East, Turkey and Vietnam, and examples of groundwater, hydropower development and forest hydrology, where there are often transboundary consequences of a state's policies and actions. In this way, the book adds empirical and theoretical insights to a still developing debate regarding the appropriate ways and means of combating climate change without undermining state and social development.

This book explores the complex problem of how to measure the 'success' of social organisations, projects and activities. Whether improving a local situation, organizing a campaign around sustainability, or assessing the intangible effects of perceived social benefits, currently we have only have a very limited range of mechanisms for judging effectiveness. On the one hand, a market-driven logic demands that qualitative perceptions and experiences are quantified into simplified and numerically defined variables. On the other, community projects are left un-assessed, as one-off outcomes of local and situated processes that must somehow automatically 'make things better'. For academics, researchers and other professionals working in this field this has resulted in the deep frustration of not being able to assess the things that are most centrally important: higher human values such as integrity, trust, respect, equality and social justice. Measuring Intangible Values argues that we can make shared social values - and their measurement - central to decisions about improving civil society. But because these social values are intangible, we need to develop ways of eliciting and validating them at the local level that can capture people's shared meanings across multiple goals and perspectives. We need to develop mechanisms for evaluating whether these values are met that use rigorous but also relevant measures. And we need to develop ways of doing this that are scalable, transferable and comparable across different kinds of organisations and fields of activity. This book will be valuable for researchers in all social science disciplines which touch on human values, such as sociology, social psychology, human geography, social policy, architecture and planning, design and community studies.

This work delivers ideas, comments and projects on energy, communications, transport, management, human resources, and financial and legal issues which macroengineering can contribute towards the solution of the Earth's environmental problems. Some 20 engineers and scholars identify problems in the next century whose solutions call for international policy planning and a more collaborative, peaceful and prosperous world order.
Imaginative concepts employ forward thinking for applying technology in revolutionary projects. The book presents results of research on a triple helical turbine capable of extracting vast amounts of energy from slow-moving water, an invention which could harness rivers and ocean currents, rendering high dams (with their political, social and ecological implications) redundant. These turbines are already in mass production in the USA for use in the Gulf Stream to produce energy and hydrogen fuel, and can also be used to harness power from the wind.
Another project, for which the technology is already available, will harvest solar energy by satellites stationed beyond our atmosphere and beam it to the Earth; and yet another calls for planetary defence of Earth against asteroid collisions. The environmental section discusses large projects for changing our climate, planning and costing for a sub-Mediterranean aqueduct connecting the River Rhone in France with Algeria, and plans for intensive fish farming of the oceans. The role of satellites includes telemedicine, and there are Swiss plans for further tunnelling through the Alps. Project management sections include the formation of a military-civilian conservation corps, financial and legal issues, macro-projects in China, and a forecast of 21st century macro-problems.

The factors affecting water quality are many: The increasing buying power and health concerns of the world population contribute to the creation of new products whose production and disposal lead to the release of chemicals harmful to the environment; the ever-growing world population requires a steady food supply, which increases the pressure to use even more chemicals to control various crop pests; and due to climate change, head waters, rivers, and oceans are becoming increasingly warmer, acidic, and eutrophic as the result of carbod dioxide overload. Using specific examples, Water Quality and Resource Management will address the many challenges of providing clean water to the growing world population. It will also discuss the new technologies that are being developed, for example, to treat and reuse waste waters, and the innovative monitoring approaches that help scientists to assess water quality risks. Such risk assessments are urgently needed to help draft legislations and allow enforcement to ensure accessability to quality water for all. The structure of the book will be the following: Each chapter will provide information about a specific water environment and the challenges it faces. This will be followed by discussion of the pollution effects and actions taken to redress the situation. Finally, future trends will be discussed.

The field of environmental engineering is rapidly emerging into a mainstream engineering discipline. For a long time, environmental engineering has suffered from the lack of a well-defined identity. At times, the problems faced by environmental engineers require knowledge in many engineering fields, including chemical, civil, sanitary, and mechanical engineering. Increased demand for undergraduate training in environmental engineering has led to growth in the number of undergraduate programs offered. Fundamentals of Environmental Engineering provides an introductory approach that focuses on the basics of this growing field.
This informative reference provides an introduction to environmental pollutants, basic engineering principles, dimensional analysis, physical chemistry, mass, and energy and component balances. It also explains the applications of these ideas to the understanding of key problems in air, water, and soil pollution.

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 NATO Advanced Research Workshop "Role of Interfaces in Environmental Protection" has been held on May 27-30, 2002 in Miskolc, Hungary, under leadership of co-directors Prof Sandor Barany from the University ofMiskolc, Hungary, and Prof Nataliya Klymenko, National Academy of Sciences of Ukraine. The objective of the ARW was to highlight colloidal and biocolloidal aspects of environmental pollution and technologies to monitor, remediate, abate and prevent pollution. It is known that the solution of majority of environmental problems is closely connected with phenomena at the interfaces. The behaviour, transport of dispersed particles in the environment, the main phase separation methods in water treatment, purification of liquids, aerosols removal, many soil remediation processes as well as the methods of protection of human organisms from hazardous matters, are based on concepts of colloid chemistry, i.e. properties of interfaces and their behaviour in different media. Examples of these methods are: filtration, ultrafiltration, flotation, coagulation, hetero-coagulation and flocculation, adsorption, adhesion of micro-organisms to surfaces, membrane separation methods, etc. A very important and special aspect of the topic is the human protection using colloid-chemical approaches, i.e. the adsorption, aggregation and adagulation properties of differe t materials. Examples are: adsorption of hazardous organic materials, drugs, heavy. metals and radionuclides on activated carbon, silica, cellulose derivatives, etc."

This book uses narrative responses to the 2010 Haiti earthquake as a starting point for an analysis of notions of disaster, vulnerability, reconstruction and recovery. The turn to a wide range of literary works enables a composite comparative analysis, which encompasses the social, political and individual dimensions of the earthquake. This book focuses on a vision of an open-ended future, otherwise than as a threat or fear. Mika turns to concepts of hinged chronologies, slow healing and remnant dwelling. Weaving theory with attentive close-readings, the book offers an open-ended framework for conceptualising post-disaster recovery and healing. These processes happen at different times and must entail the elimination of compound vulnerabilities that created the disaster in the first place. Challenging characterisations of the region as a continuous catastrophe this book works towards a bold vision of Haiti's and the Caribbean's futures. The study shows how narratives can extend some of the key concepts within discipline-bound approaches to disasters, while making an important contribution to the interface between disaster studies, postcolonial ecocriticism and Haitian Studies.

The history of gears with asymmetric teeth is not sufficiently recorded in modern gear literature, with some gear researchers concluding that asymmetric tooth gears were discovered just several decades ago. This book sheds light upon the origins and state of asymmetric gearing, referencing technical articles from the 19th, 20th, and 21st centuries. As a practicing gear engineer with over 40 years' experience, author Alexander L. Kapelevich has successfully implemented asymmetric gears in a variety of custom gear transmissions. This book addresses all aspects of asymmetric gear development, including theoretical fundamentals; tooth geometry optimization; stress analysis and rating; design and production specifics; analytical and experimental comparison to the best symmetric gears; and application examples. Readers are encouraged to look beyond the status quo established by traditional gear design, and to apply principles of asymmetric gearing to actual gear design. Optimal solutions are presented for gear drives that will maximize technical performance and marketability. Features Presents a state-of the-art, comprehensive historical overview of asymmetric gearing Explains the Direct Gear Design (R) approach to asymmetric gear design Describes asymmetric tooth gear geometry optimization, areas of existence, and parameter selection limits Considers practical aspects of asymmetric gear fabrication and measurement Presents analytical and experimental comparison of asymmetric gears to advanced symmetric gears, showing the advantages of asymmetric designs Provides numerous real-world examples of asymmetric gear application

Environmental Chemistry is a relatively young science. Interest in this subject, however, is growing very rapidly and, although no agreement has been reached as yet about the exact content and limits of this interdisciplinary discipline, there appears to be increasing interest in seeing environmental topics which are based on chemistry embodied in this subject. One of the first objectives of Environ mental Chemistry must be the study of the environment and of natural chemical processes which occur in the environment. A major purpose of this series on Environmental Chemistry, therefore, is to present a reasonably uniform view of various aspects of the chemistry of the environment and chemical reactions occurring in the environment. The industrial activities of man have given a new dimension to Environ mental Chemistry. We have now synthesized and described over five million chemical compounds and chemical industry produces about hundred and fifty million tons of synthetic chemicals annually. We ship billions of tons of oil per year and through mining operations and other geophysical modifications, large quantities of inorganic and organic materials are released from their natural deposits. Cities and metropolitan areas of up to 15 million inhabitants produce large quantities of waste in relatively small and confined areas. Much of the chemical products and waste products of modern society are released into the environment either during production, storage, transport, use or ultimate disposal. These released materials participate in natural cycles and reactions and frequently lead to interference and disturbance of natural systems."

Energy is central to the fabric of society. This book revisits the classic notions of energy impacts by examining the social effects of resource extraction and energy projects which are often overlooked. Energy impacts are often reduced to the narrow configurations of greenhouse gas emissions, chemical spills or land use changes. However, this neglects the fact that the way we produce, distribute and consume energy shapes society, political institutions and culture. The authors trace the impacts of contemporary energy and resource extraction developments and explain their significance for the shaping of powerful social imaginaries and a reconfiguration of political and democratic systems. They analyse not only the complex histories and landscapes of industrial mining and energy development, including oil, coal, wind power, gas (fracking) and electrification, but also their significance for contested energy and social futures. Based on ethnographic and interdisciplinary research from around the world, including case studies from Australia, Germany, Kenya, the Netherlands, Nicaragua, Norway, Poland, Turkey, UK and USA, they document the effects on local communities and how these are often transformed into citizen engagement, protest and resistance. This sheds new light on the relationship between energy and power, reflecting a wide array of pertinent impacts beyond the usual considerations of economic efficiency and energy security. The volume is aimed at advanced students and researchers in anthropology, sociology, human geography, science and technology studies, environmental studies and sustainable development as well as professionals working in the field of impact assessments.
