Environmental contamination in cold regions poses unique problems. It affects traditionally pristine areas and presents substantial operational difficulties. The extreme temperature range, soils and geology, the unique biological diversity, the freezing and thawing of pollutants, and the impact of human activities make environmental site assessment

The United States is an important food producer globally, in part because of its abundance of agriculturally productive soils. However, management practices that maximize yields have caused losses in soil organic matter, poor soil structure and water-holding capacity, and increased salinity on millions of acres of land - and have adversely affected the microbial communities that are the drivers of many soil processes. At the same time, recent scientific advances have spurred interest in how microbial communities can support soil health, food quality, and human health. It is in this context that the U.S. Department of Agriculture National Institute of Food and Agriculture asked the National Academies to explore the linkages between soil health and human health. The report finds that to improve soil health, federal agencies need to promote the importance of soil health, support translational research, and develop a coordinated national approach to monitor soil health over time and space. Given the potential that microbiomes have in modulating soil, plant, and human health, there is also a pressing need to determine which microbial features, if any, contribute to quantifying or fortifying health in both human and soil systems and to understand the direct and indirect roles of soil, alongside other environmental factors, in influencing human microbial colonization and subsequent health outcomes. Such investigation involves delving into the relatively sparse or disconnected research regarding the microbiome continuum that links soil and human systems.

Containing more than 300 entries and essays interspersed throughout, it uses the most current scientific data to explain the different types of pollutants including properties, production, uses, environmental release and fate, adverse health response to exposure, and environmental regulations on human exposure. It provides the scientific background on the water, soil, and air of environments where the pollutants are released. Coverage also includes pollution regulation, the function of federal regulatory agencies and environmental advocacy groups, and the technology and methods to reduce pollution and to remediate existing pollution problems. Numerous case studies explore the most infamous of pollution events such as the Exxon Valdez oil spill, the Gulf War oil well fires, the Chernobyl disaster, Hurricane Katrina, the World Trade Center disaster, and the Love Canal in New York, among many others—including those that had great impact on legislation or that were used in popular media such as the films Erin Brockovich and A Civil Action. Biographies are provided of some of the leaders and pioneers of pollution study and activism. Other useful features include a detailed glossary, a timeline, and tables.

Addresses all aspects of pollution and the global impact on the environment; contains numerous entries and essays using the most current scientific data to explain the different types of pollutants.

This updated edition of the 1992 reference work ('exhaustive...fascinating'--Library Journal) contains comprehensive information about United States military cemeteries, including how each cemetery was chosen, why it was established, and notable individuals buried therein. Covered are cemeteries operated by the Department of Veterans Affairs, the Department of the Army, the National Park Service, the American Battle Monuments Commission, and the various states, among others, along with smaller and'lost'cemeteries. Appendices provide lists of installations by state and by year of establishment, as well as information on headstones, markers and the Medal of Honor.

Taken from the pages of Science and supplemented by contributions from the magazine's editors, State of the Planet 2008-2009 offers contemporary science writing that is sometimes provocative, frequently enlightening, and always authoritative. Published by the American Association for the Advancement of Science (AAAS), Science is one of the most respected scientific magazines in the world. With a readership of more than one million people, it offers “hard science” from top scientists to both educated lay readers and scientists alike. The articles collected here are arranged thematically and each section is introduced by a prominent scientist or science writer. Donald Kennedy, who was Editor-in-Chief of Science when these articles appeared in the magazine, contributes a preface and several short essays. Focusing on issues of energy and sustainability, sections of the volume are devoted to the prospects of energy-sparing technologies and alternatives to fossil fuel use, including ethanol and cellulosic digestion. Other sections center on climate change, led by a comprehensive essay on the state of scientific knowledge today and followed by contributions about the Antarctic and Greenland ice sheets, as well as the effects of climate change that have been measured to date, including changes in migration and breeding cycles of birds and flowering in plants, changing patterns of hurricanes and extreme weather events, and alterations in forest fire frequency. Interspersed throughout the book are Science news pieces that highlight particular issues and cases relevant to the main scientific findings. A glossary of key terms and concepts helps students and nonspecialists better understand the terminology and the issues.
