  • Our global environment now consists of numerous natural and artificial metals. Metals have played a critical role in industrial development and technological advances. Most metals are not destroyed; indeed, they are accumulating at an accelerated pace, due to the ever-growing demands of modern society. A fine balance must be maintained between metals in the environment and human health. It is with this view in mind that this book has been written to address diverse issues surrounding heavy metals in the environment.

  • Because of the potential public health implications, the importance of toxic air pollutants in ambient air has been recognized to some degree for many years. Efforts to “regulate” human activities resulting in the production of ambient air pollutants probably date back many centuries, even as the combustion of fossil fuels and air pollution from other organized human activities began having a noticeable impact on the environment.

  • The most significant issues facing mankind today are related to the quality of our environment. Past decisions did not always consider environmental factors as critical elements. However, current decisions made daily should reflect the importance of the environment. All environment-related issues are multidisciplinary, ranging from science and engineering to social, economic, and regulatory issues. Further, these issues are not related to any one region or country, but are global in nature, requiring multidisciplinary, multiorganizational, and multinational educational efforts....

  • The specific problems associated with concrete and concreting in hot environments have been recognised for some decades. This recognition has manifested itself over the years at a few symposia and in hundreds of papers where relevant research results and field observations were presented and discussed. In other publications the practical conclusions from these available data and experiences have been summarised in the form of guidelines for hot climate concreting.

  • Enzymes that function within plants, animals, and microorganisms are fundamental to life, and their contributions to metabolic pathways and processes have been studied extensively. For over 100 years there has been interest in what today is called ecological or environmental enzymology. This aspect of enzymology originates from the work of Woods, who, in 1899, wrote about the survival and function in soil of plant peroxidases following their release from decaying plant roots.

  • On average, one ton of hazardous waste per person is generated annually by industries in the United States. Before the Resource Conservation and Recovery Act of 1984, hazardous wastes were improperly disposed of into the environment without any regulation. As a result, remediation of these contaminated sites and management of the ongoing hazardous waste sources are two major tasks to be achieved by treatment technologies.

  • A large amount of information has accumulated on humic acids and related substances, which warrants the creation of an independent science of humic compounds. Two different concepts have emerged from the maze of data, one claiming humic compounds to be operational or fake compounds, produced by the analytical extraction procedures, and the other considering them to be natural compounds occurring in soils, rivers, lakes, oceans and their sediments.

  • Evidence grows daily of the rapid changes in climate due to human activities and their impact on plants and animals. Plant function is inextricably linked to climate and atmospheric carbon dioxide concentration. On the shortest and smallest scales the climate affects the plant’s immediate environment and thus directly influences physiological processes. On longer and larger time and space scales climate influ- ences species distribution and community composition and determines what crops can be viably produced in managed agricultural, horticultural and forestry ecosys- tems.

  • This volume aims at providing a coherent presentation of recent developments and understanding of heavy metal reactivity in soils. Such an understanding is necessary in addressing heavy metals concerns in the environment. The implicit framework of multiple reactivity acknowledges the widely known role played by the various colloidal surface functional groups in concomitant reactions. This overarching frame of reference allows unification between molecular structure-reactivity relationships at one scale and transport processes at the other....

  • When I began my professional career at the University of Nebraska–Lincoln in 1979, I intended to direct my research and outreach program at the emerging field of climate impact science. It was fortuitous that a large portion of the United States, including the Great Plains, Upper Midwest, and Pacific Northwest, had recently come out of an intense but somewhat short-lived drought during 1976-1977.

  • The idea for this book began over ten years ago through conversations with Clive Edwards, editor of an agroecosystems series of books. It was clear to both of us that the human intersect with the environment is mediated by social forces that are international, national, and local. But at that point there was little research to demonstrate the nature of the relationships between human institutions and ecosystems.

  • Several years ago the Open University in Heerlen and Maastricht University decided to launch a course on ‘Climate and the Environment’, with a diverse team of authors. Both natural and social scientists, from several regions of the world, contributed to this book. Initially, the book was intended as a textbook within this course for students of Environmental Sciences programmes at the Open University and Maastricht University. As the book developed it became clear that it would be an excellent source to anyone professionally engaged in the wide area of the enhance greenhouse effect....

  • Twenty years ago, world leaders gathered at the Earth Summit in Rio de Janeiro and signed the first global agreement to tackle climate change. At the time, the impacts of climate change on communities and economies were just beginning to be understood, and the role of the private sector in responding to these challenges was only just emerging. But two decades later, climate change is no longer a distant threat looming on the horizon; it has emerged as arguably the greatest global challenge of our time.

  • Carbon offsets are an innovative tool for allowing companies and individuals to reduce greenhouse gas emissions beyond what they can easily achieve on their own. In the past two years, interest in carbon offsets has grown dramatically as companies and concerned consumers have sought ways to help mitigate climate change. However, the global market for voluntary carbon offsets is currently unregulated, which has led to growing concerns about whether buyers are really getting what they are paying for.

  • In 1992, the first United Nations Conference on Sustainable Development, popularly known as the Rio Earth Summit, was convened in Rio de Janeiro, Brazil to address the state of the environment and sustainable development. The Earth Summit yielded several important agreements including “Agenda 21”, a plan of action adopted by over 178 governments to address human impacts on the environment at local, national and global levels, and key treaties on climate change, desertification and biodiversity.

  • Understanding the origins of humanity has long been one of our foremost intellectual pursuits, and one that greatly interests the general public as evidenced by museum attendance and by numerous media productions and general interest publications. Progress toward an improved understanding of our heritage is a continuing challenge for the scientific community, requiring advances in a range of disciplines that include archaeology, anthropology, geology, biology, oceanography, and genetics, and particularly research advances in areas where two or more of these fields intersect.
