Catastrophes are part of Earth's real history. Its grim disasters, acting as a backdrop against which human dramas have been played out, have been recorded in many ancient writings. As Milne shows, doomsday catastrophism, once the prerogative of 18th-century geologists steeped in the Biblical memory of the Great Flood, has now regained respectability. Catastrophism applies to many disciplines such as planetary science, biology, climatology, and evolutionary theory. The universe itself, we now believe, is a product of a giant cosmic catastrophe. Indeed life itself may have arisen when the moon may have crystallized out of a crashing mini-planet that enabled organisms to emerge into tidal pools. Floods and natural disasters seem to be on the increase everywhere and are no longer just a Third World problem. The fear of climatic disturbances are the source of regular international conferences, and it is seriously suggested that the U.S. military shoot down plummeting comets before they destroy civilization, as they once destroyed the dinosaurs. Milne provides a contemporary look at catastrophism in its scientific and in its disastrous earth-shattering sense. Within one volume a wide range of up-to-date scientific facts and concepts are examined. Milne gives readers interested in scientific controversies, contemporary affairs and environmental issues an important document that chronicles the end of a turbulent and disturbing 2,000 years.

Emphasizing new science essential to the practice of environmental
chemistry at the beginning of the new millennium, this book
describes the atmosphere as a distinct sphere of the environment
and the practice of industrial ecology as it applies to chemical
science. It includes extensive coverage of nuclear chemistry,
covering both natural environmental sources and anthropogenic
sources, their impacts on health, and their role in energy
production, that goes well beyond the newspaper coverage to discuss
nuclear chemistry and disposal in a balanced and scientifically
rational way.
Fluids, play an important role in environmental systems, appearing as surface water in rivers, lakes, and coastal regions or in the subsurface as well as in the atmosphere. Mechanics of environmental fluids is concerned with fluid motion, associated mass and heat transport in addition to deformation processes in subsurface systems. In this textbook the fundamental modelling approaches based on continuum mechanics for fluids in the environment are described, including porous media and turbulence. Numerical methods for solving the process governing equations and its object-oriented computer implementation are discussed and illustrated with examples. Finally the application of computer models in civil and environmental engineering is demonstrated.
This book provides a concise, yet comprehensive overview of the many facets relating to human health risk assessments in relation to chemical exposure problems. It presents some very important tools and methodologies that can be used to address chemical exposure and public health risk management problems in a consistent, efficient, and cost-effective manner. On the whole, the book represents a collection and synthesis of the principal elements of the risk assessment process that may be used to more effectively address issues pertaining to human exposures to chemicals found in modern societies. This also includes an elaboration of pertinent risk assessment concepts and techniques/methodologies for performing human health risk assessments. Written for both the novice and the experienced, the subject matter of this book is an attempt at offering a simplified and systematic presentation of public health risk assessment methods and application tools - all these facilitated by a layout that will carefully navigate the user through the major processes involved. A number of illustrative example problems are interspersed throughout the book, in order to help present the book in an easy-to-follow, pragmatic manner.
An advanced exploration ofwater-rock interactions Based on the author's fifteen years of teaching and tried-and-tested experiences in the classroom, here is a comprehensive exploration of water-rock interactions. "Environmental Surfaces and Interfaces from the Nanoscale to the Global Scale" covers aspects ranging from the theory of charged particle surfaces to how minerals grow and dissolve to new frontiers in W-R interactions such as nanoparticles, geomicrobiology, and climate change. Providing basic conceptual understanding along with more complex subject matter, Professor Patricia Maurice encourages students to look beyond the text to ongoing research in the field. Designed to engage the learner, the book features: Numerous case studies to contextualize conceptsPractice and thought questions at the end of each chapterBroad coverage from basic theory to cutting-edge topics such as nanotechnologyBoth basic and applied science This text goes beyond W-R interactions to touch on a broad range of environmental disciplines. While written for advanced undergraduate and graduate students primarily in geochemistry and soil chemistry, "Environmental Surfaces and Interfaces from the Nanoscale to the Global Scale" will serve the needs of such diverse fields as environmental engineering, hydrogeology, physics, biology, and environmental chemistry.
Nowadays, environmental issues including air and water pollution, climate change, overexploitation of marine ecosystems, exhaustion of fossil resources, conservation of biodiversity are receiving major attention from the public, stakeholders and scholars from the local to the planetary scales. It is now clearly recognized that human activities yield major ecological and envir- mental stresses with irreversible loss of species, destruction of habitat or c- matecatastrophesasthemostdramaticexamplesoftheire?ects.Infact, these anthropogenic activities impact not only the states and dynamics of natural resources and ecosystems but also alter human health, well-being, welfare and economic wealth since these resources are support features for human life. The numerous outputs furnished by nature include direct goods such as food, drugs, energy along with indirect services such as the carbon cycle, the water cycle and pollination, to cite but a few. Hence, the various ecological changes our world is undergoing draw into question our ability to sustain economic production, wealth and the evolution of technology by taking natural systems into account. The concept of "sustainable development" covers such concerns, although no universal consensus exists about this notion. Sustainable development - phasizes the need to organize and control the dynamics and the complex - teractions between man, production activities, and natural resources in order to promote their coexistence and their common evolution. It points out the importance of studying the interfaces between society and nature, and es- ciallythecouplingbetweeneconomicsandecology.Itinducesinterdisciplinary scienti?c research for the assessment, the conservation and the management of natural resources.
This book is concerned with the causes and consequences of river and coastal floods and the ways in which people can respond to the flood hazard. Individual chapters address issues such as floods as natural hazards; impacts and interpretations of flood hazard; causes, spatial characteristics and form of river floods and coastal floods; flood estimation; flood defence; flood forecasting and warning; other responses including land use planning and insurance; and a concluding discussion of problems, policies and prospects. Floods has been written by two experienced and successful authors whose complementary skills are combined to give a broad, comprehensive and up-to-date treatment of the subject which can be used not only as a text book or learning manual but also as an authoritative reference source. This has been achieved by organising and structuring the material to demonstrate the continuity and linkages between the causes and impacts of flooding and the many possible responses to the flood hazard. At the same time the book ensures that discussion of each of the main themes and topics is, as far as is practicable, self-contained. The book is timely in several aspects. It addresses the topicality and universality of floods which are an increasing hazard at a time of global environmental change (climate, land use, population distribution etc.). It also offers the layman and practitioner alike a synthesis and clarification of many individual research efforts near the close of the International Decade for Natural Disaster Reduction.
Homer speaks of lightning bolts after which 'a grim reek of sulphur bursts forth' and the air was '?lled with reeking brimstone'. (Homer 3000 BC). The odour was not actually the smell of sulphur dioxide associated with burning sulphur, but rather was the ?rst recorded detection of the presence of another strong odour, that of ozone (O ) in Earth's atmosphere. These molecules were formed by the passage of 3 lightning through the air, created by splitting the abundant molecular oxygen (O ) 2 molecules into two, followed by the addition of each of the free O atoms to another O to form the triatomic product. In fact, most of the ozone molecules present 2 in the atmosphere at any time have been made by this same two-step splitti- plus-combination process, although the initiating cause usually begins with very energetic solar ultraviolet (UV) radiation rather than lightning. Many thousands of years later, the modern history of ozone began with its synthesis in the laboratory of H. F. Schonbein in 1840 (Nolte 1999), although the positive con?rmation of its three-oxygen atom chemical formula came along sometime later. Scienti?c interest in high-altitude stratospheric ozone dates back to 1881 when Hartley measured the spectrum of ozone in the laboratory and found that its ability to absorb UV light extended only to 293nm at the long wavelength end (Hartley 1881a).
Mercury (Hg) is one of the most toxic heavy metals, harmful to both the environment and human health. Hg is released into the atmosphere from natural and anthropogenic sources and its emission control has caused much concern. This book introduces readers to Hg pollution from natural and anthropogenic sources and systematically describes coal-fired flue gas mercury emission control in industry, especially from coal-fired power stations. Mercury emission control theory and experimental research are demonstrated, including how elemental mercury is oxidized into oxidized mercury and the effect of flue gas contents on the mercury speciation transformation process. Mercury emission control methods, such as existing APCDs (air pollution control devices) at power stations, sorbent injection, additives in coal combustion and photo-catalytic methods are introduced in detail. Lab-scale, pilot-scale and full-scale experimental studies of sorbent injection conducted by the authors are presented systematically, helping researchers and engineers to understand how this approach reduces the mercury emissions in flue gas and to apply the methods in mercury emission control at coal-fired power stations. Readers will arrive at a comprehensive understanding of various mercury emission control methods that are suitable for industrial applications. The book is intended for scientists, researchers, engineers and graduate students in the fields of energy science and technology, environmental science and technology and chemical engineering.
The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution - air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste production, the seemingly idealistic demand for "zero discharge" can be construed as an unrealistic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci c pollution problems has been a major contributing factor to the success of environmental engineering, and has accounted in large measure for the establishment of a "methodology of pollution control. " However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.
Covers the entire process of risk management by providing methodologies for determining the sources of engineering project risk, and once threats have been identified, managing them through: identification and assessment (probability, relative importance, variables, risk breakdown structure, etc.); implementation of measures for their prevention, reduction or mitigation; evaluation of impacts and quantification of risks and establishment of control measures. It also considers sensitivity analysis to determine the influence of uncertain parameters values on different project results, such as completion time, total costs, etc. Case studies and examples across a wide spectrum of engineering projects discuss such diverse factors as: safety; environmental impacts; societal reactions; time and cost overruns; quality control; legal issues; financial considerations; and political risk, making this suitable for undergraduates and graduates in grasping the fundamentals of risk management.
As a result of arms control efforts over the past 50 years, nuclear material is subject to strict national controls and tough international treaties. But there are still almost no controls, other than a voluntary International Atomic Energy Agency code of conduct, on the sorts of radiological sources used to make radiological dirty bombs. Radiological sources are used all over the world for a wide range of peaceful purposes, including smoke detectors, medical devices, meteorology, mining and thermoelectric generators. There are at least eight million identified radiological sources worldwide. Their small size, portability and high value make them vulnerable to misuse and theft: the IAEA reported 272 cases of illicit trafficking in sealed radioactive sources between 1993 and 2002. The IAEA estimates that 110 countries worldwide still fail to impose adequate controls. The time is ripe for an international convention and treaty on the safety and security of radiological sources. This book covers expert discussions designed to enhance cooperation and assistance between NATO and Partner countries in support of International Atomic Energy Agency (IAEA) efforts to secure radioactive sources against the threat of terrorism and also to support the security agenda at the International Radiation Protection Association Congress in Buenos Aires in 2008.
The interactions of biogeochemical cycles influence and maintain
our climate system. Land use and fossil fuel emissions are
currently impacting the biogeochemical cycles of carbon, nitrogen
and sulfur on land, in the atmosphere, and in the oceans.
This book explores the challenges that confront leaders in government and industry when making decisions in the areas of environmental health and safety. Today, decision making demands transparency, robustness, and resiliency. However thoughtfully they are devised, decisions made by governments and enterprises can often trigger immediate, passionate public response. Expertise Under Scrutiny shows how leaders can establish organizational decision making processes that yield valid, workable choices even in fast-changing and uncertain conditions. The first part of the book examines the organizational decision making process, describing the often-contentious environment in which important environmental health and safety decisions are made, and received. The authors review the roles of actors and experts in the decision making process. The book goes on to address such topics as: * The roles of actors and experts in the decision making process * Ethics and analytics as drivers of good decisions * Why managing problems in safety, security, environment, and health Part II offers an outline for adopting a formal decision support structure, including the use of decision support tools. It includes a chapter devoted to ELECTRE (ELimination and Choice Expressing Reality), a multi-criteria decision analysis system. The book concludes with an insightful appraisal and analysis of the expertise, structure and resources needed for navigating well-supported, risk-informed decisions in our 21st Century world. Expertise Under Scrutiny benefits a broad audience of students, academics, researchers, and working professionals in management and related disciplines, especially in the field of environmental health and safety.

Solutions are needed that represent practical alternatives to costly remedial strategies yet still yield benefits to site managers. This publication comprises the presentations made at the NATO Advanced Research Workshop held in Sinaia, Romania 9 a 11 October, 2006. The contributions represent a wide range of issues and challenges related to contaminated site management from low cost solutions to petroleum contaminated sites to advances in biological treatment methods. This publication is meant to foster links between groups facing challenges cleaning up contaminated sites through presentations that explore the problems currently being addressed and solutions that are emerging in the field.
This book focuses in the current situation of water resources, water supply and sanitation, and population movement in Latin America. It identifies new phenomena and challenges that will put more pressure on water resources in the near future and that will create important socioeconomic constraints in population and their governments. This volume offers an evaluation of water resources availability and consumption, water supply and sanitation shortages, management models and population growth and territory occupation trends in eighteen Latin American countries. Also a set of recommendations, policy proposals and projects is outlined.
The management of water supply and quality in lakes, rivers, and reservoirs has proceeded largely on the basis of local rather than global considerations. High-quality freshwater resources are now in critically short supply, not only because of local problems such as over-irrigation and eutrophication, but also as a result of large-scale impacts such as climate effects on the hydrosphere. This book explores the dichotomy of global strategies (international and generic) versus local strategies (site-specific) for lake, river, and reservoir management, and presents a series of contrasting perspectives on topics that include monitoring, modeling, water treatment, eutrophication, and restoration. The final chapter integrates these perspectives and identifies strengths, weaknesses, and complementary aspects of the two approaches to help refine future strategies for the sustainable use of the world's freshwater resources. |
