Human activity has more than doubled the rate of creation of reactive nitrogen on the land surface of the earth over natural levels, with much of this change occurring in recent decades. Major drivers behind this increase are population growth, agricultural intensification, and emissions of nitrogen pollutants to the atmosphere from the combustion of fossil fuels. As a result, nitrogen is accumulating in the landscape and in water at unprecedented levels, and is connected to a host of environmental problems including effects on natural ecosystems and on human health. For example, eutrophication caused by excessive inputs of N from landscapes to the oceans is one of the greatest factors altering water quality in coastal ecosystems worldwide.

This synthesis is the final report from the International SCOPE Project on Nitrogen Transport and Transformations: A Regional and Global Analysis. SCOPE (the Scientific Committee on Problems of the Environment) authorized the Nitrogen Project because of the need to better understand how humans have altered nitrogen cycling globally and at the scale of large regions. The project has synthesized information through a series of workshops over the past 8 years, involving over 250 scientists from over 20 different nations. Papers in this volume explore the extent to which human activity has affected the nitrogen cycle in terrestrial regions and in the world's oceans, and discuss the implications of accelerated nitrogen cycling for nature and society.

Ecological assessments are a critical component of land management planning and regulatory decision-making. In the United States, for example, the National Environmental Policy Act of 1969 directs that the environmental consequences associated with proposed management of federal lands be fully disclosed to the general public through environmental impact assessments. In a similar manner, over 40 other countries have legislated the use of some type of ecological assessment as a prerequisite for effective environmental planning and land management. Although ecological assessments can be conducted at a variety of spatial scales and may address one or many issues, the main intent of this book is to describe topics with particular importance to strategic integrated ecological assessments at a regional or subregional scale. The chapters in this book range from overviews of basic ecological principles, to suggestions concerning ecosystem characterization and analysis, to systematic reviews of selected case studies. In this respect, the book provides both theoretical and practical advice for future ecological assessments given specific land use planning objectives. This book will be the reference standard for any person engaged in any ecological assessment exercise at any level, whether they work for national, state or regional authorities or in academia.

The field of endocrine disruption or endocrine active compounds (EACs), which is just emerging and still controversial, is comprehensively covered by leading experts in Volume 3, Subvolumes L (Part I) and M (the present volume, Part II). The major classes of endocrine active chemicals are discussed, as well as methods for their detection and their association with health disturbances in humans and wildlife. The etiology of several of the human diseases associated with endocrine disruptors, e.g. breast and prostate cancer, decreased fertility and malformations, is still poorly understood, and the current state of knowledge is presented. Since hormonally active agents appear to have the potential of both adverse and beneficial effects, the evidence of health benefits associated with endocrine active compounds in humans is also presented. Basic chapters on the mode of action of EACs and on the etiology of the associated diseases facilitate the understanding of this complex subject for non-medical readers.

This new volume on Environmental Photochemistry up-dates the previous edition with chapters on basic aspects including concepts of photochemical transformations and mechanistic photochemical processes in the atmosphere and water. In addition a range of applications are also detailed such as advanced photochemical oxidation processes for water and air treatment as well as applications of photocatalysis for surface treatment and nuclear fuel reprocessing. The new edition provides a critical up to date overview of the most important research in the field of environmental photochemistry.

In the modern world, industries and factories are rising exponentially. This has led to the mass cultivation of non-biodegradable products, like heavy metals, that have polluted the environment and become a major threat to plant growth, crop yield, and human health. Conventional remediation technologies are expensive and may not remove contaminates effectively. Therefore, it is important to develop economically practical and more effective methods to decontaminate soils. Nano-Phytoremediation Technologies for Groundwater Contaminates: Emerging Research and Opportunities is a collection of innovative research on the methods and applications of the use of plants for remediating metal-contaminated soil and water. While highlighting topics including molecular mechanisms, nutrient interference, and fluoride accumulation, this book is ideally designed for environmental scientists, environmental engineers, agriculturalists, farmers, policymakers, government officials, research scholars, professors, and students studying in the fields of environmental engineering, biotechnology, nano-technology, bioscience, and environmental science.

Humans rank with the powerful forces of nature transforming Earth. Since the mid-20th century, population growth, industrialization, and globalization have had such deep and wide-ranging impacts that our planet no longer functions as it did during the previous eleven millennia. So distinctive is this collective human intervention that a new geological interval has been proposed; it is called the Anthropocene. The Anthropocene is intriguing scientifically, fascinating intellectually, and deeply disturbing politically, socially, economically, and ethically. We must learn how to co-exist sustainably with the rest of nature in what is emerging as a new planetary state. To do so, we must first understand what "Anthropocene" means in all its dimensions. This book adopts a multidisciplinary approach, starting with an exploration of the Anthropocene as a geological concept: ranging across the physical changes to the landscape, to the rapidly heating climate, to a biosphere undergoing transformation. And what of the "anthropos" in the Anthropocene? While geoscience does not normally address political and ethical issues of justice and equity, or economics and culture, Anthropocene studies in the humanities and social sciences investigate the complexities of the human activity driving global change. Here the book looks at human history, both in the deep past and more recently, the politics and economics of growth spurring the Anthropocene, and potential ways of mitigating its cruel effects. Our fragile, still beautiful, planet is finite. The new realities of the Anthropocene will need our best efforts, across disciplinary divides, at effective hope and action.

Cosmogenic radionuclides are radioactive isotopes which are produced by natural processes and distributed within the Earth system. With a holistic view of the environment the authors show in this book how cosmogenic radionuclides can be used to trace and to reconstruct the history of a large variety of processes. They discuss the way in which cosmogenic radionuclides can assist in the quantification of complex processes in the present-day environment. The book aims to demonstrate to the reader the strength of analytic tools based on cosmogenic radionuclides, their contribution to almost any field of modern science, and how these tools may assist in the solution of many present and future problems that we face here on Earth. The book provides a comprehensive discussion of the basic principles behind the applications of cosmogenic (and other) radionuclides as environmental tracers and dating tools. The second section of the book discusses in some detail the production of radionuclides by cosmic radiation, their transport and distribution in the atmosphere and the hydrosphere, their storage in natural archives, and how they are measured. The third section of the book presents a number of examples selected to illustrate typical tracer and dating applications in a number of different spheres (atmosphere, hydrosphere, geosphere, biosphere, solar physics and astronomy). At the same time the authors have outlined the limitations of the use of cosmogenic radionuclides. Written on a level understandable by graduate students without specialist skills in physics or mathematics, the book addresses a wide audience, ranging from archaeology, biophysics, and geophysics, to atmospheric physics, hydrology, astrophysics and space science.

Should there be firmer restrictions on trade, with more policies aimed at protecting its environmental impacts, or would the environment benefit most from unrestricted free trade? Do importing countries have a responsibility only to their local ecosystems, or are they also responsible for environmental degradation caused by the production of traded goods in exporting countries? Trading the Environment examines both the dependence and the effects of international trade on the earth's life support systems and looks at ways in which trading regulations could be adapted to promote ecologically sustainable economic development. It addresses the issues from a fully integrated approach, focusing on the interrelations between ecosystems, economic development and trade. The authors provide a carefully constructed ecological and economic analysis of trade and the environment, examine the existing legal and institutional frameworks and set out 16 recommendations to achieve environment beneficial trade at both national and international levels. Trading with the environment was originally commissioned by the Swedish government and is already regarded thereon essential reference. It makes an excellent introduction as well as constructive analysis, both for students and for policy-makers and professional economics and other scientists working on the issues. Published in 1995

This handbook on power systems consists of a set of 4 volumes. These books are carefully planned and designed to provide the state of art material on major aspects of electrical power systems, short-circuit currents, load flow, harmonics and protective relaying. Many aspects of power systems are transparent between different types of studies and analyses; knowledge of short-circuit currents and symmetrical component is required for protective relaying, and fundamental frequency load flow is required for harmonic analysis. Currently, power systems, large or small, are analyzed on digital computers with appropriate software. However, it is necessary to understand the theory and basis of these calculations to debug and decipher the results. The material is organized with sound theoretical base, practical applications, and case studies based on the author's 45+ years of experience with real world problems.

This book discusses UV radiation, its effects on ecosystems and the likely evolutionary consequences of changed UV radiation environments, past, present and future. The first two chapters examine the history of the UV radiation climate of earth and the factors that determine organismal and ecosystem exposure. Their purpose is to give the reader a physical perspective on UV radiation and an understanding of the constantly changing UV environment that ecosystems are exposed to over time. Variations in the UV radiation environment occur at the local level (such as boundary layer and plant canopy effects) through to global-scale changes (such as alterations in the column abundance of UV-B protecting ozone). UV radiation regimes also vary over temporal scales. These alterations occur on time scales of seconds (the movement of clouds and plant canopies) to literally billions of years (gross long-term changes in the composition of the Earth's atmosphere). In the chapters that follow five specific biological and ecological topics in photobiology are considered. They are effects of UV radiation on amphibians, plants, corals, aquatic microbial ecosystems and Antarctic ecosystems that are exposed to the anthropogenically generated ozone 'hole'. These chapters consider UV radiation effects at a diversity of levels from the biochemical to the community. Their purpose is to provide the reader with our current understanding of the ecological effects of UV radiation, the areas where questions still remain and to provide a perspective from which the reader can better understand questions in evolutionary photobiology. The final chapter investigates the biological consequences of altered extraterrestrial ultraviolet fluxes, which are quite different from those experienced on the Earth. Our knowledge of the role of UV radiation in shaping ecologies and evolutionary change is still in its infancy. This book brings together a number of authors with the aim of helping to consolidate a better understanding of this interesting area of photobiology.

Have you ever had to provide accurate costs for a new supermarket or a pub "just an idea...a ballpark figure..." ? The earlier a pricing decision has to be made, the more difficult it is to estimate the cost and the more likely the design and the specs are to change. And yet a rough-and-ready estimate is more likely to get set in stone. Spon's First Stage Estimating Handbook is the only comprehensive and reliable source of first stage estimating costs. Covering the whole spectrum of building costs and a wide range of related MandE work and landscaping work, vital cost data is presented as: costs per square metre elemental cost analyses principal rates composite rates. Compact and clear, Spon's First Stage Estimating Handbook is ideal for those key early meetings with clients. And with additional sections on whole life costing and general information, this is an essential reference for all construction professionals and clients making early judgements on the viability of new projects.

The last two decades have witnessed an ever growing partisan divide in US politics over climate change and global warming. Significant elements in the Republican Party became openly hostile to the scientific evidence and, following the election of George W. Bush, legislative action at the federal level effectively ground to a halt. This opened up space at the state and local level to develop climate change policies with cities such as Chicago, San Francisco and New York implementing a number of initiatives that brought real and substantive developments. The election of Barack Obama in 2008 seemed to open new possibilities for federal and global leadership once more and whilst the Obama administration has been criticised for a somewhat contradictory approach to the issue at times, there were nonetheless a number of substantive policy developments. Through a substantive and detailed analysis of the politics of climate change, this book places the evolution of US climate policy within broader debates on the nature of politics in the US and argues that there exists a latent potential, often obscured by the complexities of its political system, for America to act as a world leader on the issue. This work will appeal particularly to students and scholars in American Politics, but will also prove useful to those in the fields of general Politics, climate change, sustainability, and environmental studies.
