Papers presented by noted researchers consider the occurrence, flux, compartmentalization, and residence times of four elements recognized as significant environmental pollutants. Examines data available on these pollutants and pinpoints areas in which further research is needed. The presence of these elements in all ecological environments--oceans, freshwater systems, soils, the atmosphere, etc.--and their regional occurrence around the globe are examined in detail, as are their sources and effects on plants, animals, and humans. Particular attention is paid to lead, which is the most prevalent pollutant and poses the greatest risk to human health, especially the health of children.

This Special Issue aims to provide new insights into the issue of the mercury contamination of terrestrial and aquatic ecosystems. This ubiquitous contaminant has been used by humans for many years, resulting in global contamination. When this toxic contaminant is converted to methylmercury, it accumulates in trophic chains, which is a major issue for wildlife and human health. The nine articles contained within this Special Issue on ''Mercury and Methylmercury Contamination of Terrestrial and Aquatic Ecosystems'' endeavour to identify the historical evolution of Hg and MeHg levels in aquatic environments, and to evaluate the impact of current and historical human activities, such as mining, climate change, and soil erosion, on receptor ecosystems and food chains.

DDT is a pesticide that was once widely used to control insects. Both DDD and DDE are breakdown products of DDT. This profile includes: (1) The examination, summary, and interpretation of available toxicologic info. and epidemiologic evaluations on DDT/DDD/DDE to ascertain the levels of significant human exposure for the substance and the associated chronic health effects; (2) A determination of whether adequate info. on the health effects of DDT/DDD/DDE is available to determine levels of exposure that present a significant risk to human health of chronic health effects; and (3) Identification of toxicologic testing needed to identify the types or levels of exposure that may present significant risk of adverse health effects in humans.

This report provides a detailed snapshot of our nation's passion for wildlife and nature. It serves as a road map to guide efforts to reach more Americans to provide them with opportunities to hunt, fish, and enjoy America's wildlife and wild places. Bird/wildlife watching, hunting, fishing are not just favorite pastimes, but they share revenues from sale of licenses and tags, as well as excise taxes paid by hunters, anglers, and shooters to continue to support vital wildlife and habitat conservation efforts in every state. The report outlines the details for compilation of information and surveys to different populations and provides highlights along with statistical information represented in tables from the data collected.

As discussed in this book, a large body of evidence indicates that selenium is a cancer chemopreventive agent. Further evidence points to a role of this element in reducing viral expression, in preventing heart disease, and other cardiovascular and muscle disorders, and in delaying the progression of AIDS in HIV infected patients. Selenium may also have a role in mammalian development, in male fertility, in immune function and in slowing the aging process. The mechanism by which selenium exerts its beneficial effects on health may be through selenium-containing proteins. Selenium is incorporated into protein as the amino acid selenocysteine. Selenocysteine utilizes a specific tRNA, a specific elongation factor, a specific set of signals, and the codeword, UGA, for its cotranslational insertion into protein. It is indeed the 21st naturally occurring amino acid to be incorporated into protein and marks the first and only expansion of the genetic code since the code was deciphered in the mid 1960s.

This version of 'Shadows from the Walls of Death' is a tribute to Robert Clark Kedzie, who produced the originals of which there are now only two left in existence. They are located at the University of Michigan and Michigan State University. The originals are approximately 22 x 30 inches containing a title page and an 8 page preface followed by 86 samples cut from rolls of arsenic impregnated wallpaper. The book is sealed in a protective container and each individual page is encapsulated. This particular edition does not actually contain any arsenic. Further to that the content of this volume including both text and images are for entertainment purposes.

Having safe drinking water is important to all Americans. The Environmental Protection Agency's decision in the summer of 2001 to delay implementing a new, more stringent standard for the maximum allowable level for arsenic in drinking water generated a great deal of criticism and controversy. Ultimately at issue were newer data on arsenic beyond those that had been examined in a 1999 National Research Council report. EPA asked the National Research Council for an evaluation of the new data available. The committee's analyses and conclusions are presented in Arsenic in Drinking Water: 2001 Update. New epidemiological studies are critically evaluated, as are new experimental data that provide information on how and at what level arsenic in drinking water can lead to cancer. The report's findings are consistent with those of the 1999 report that found high risks of cancer at the previous federal standard of 50 parts per billion. In fact, the new report concludes that men and women who consume water containing 3 parts per billion of arsenic daily have about a 1 in 1,000 increased risk of developing bladder or lung cancer during their lifetime.

People are increasingly concerned about potential environmental health hazards and often ask their physicians questions such as: "Is the tap water safe to drink?" "Is it safe to live near power lines?" Unfortunately, physicians often lack the information and training related to environmental health risks needed to answer such questions. This book discusses six competency based learning objectives for all medical school students, discusses the relevance of environmental health to specific courses and clerkships, and demonstrates how to integrate environmental health into the curriculum through published case studies, some of which are included in one of the book's three appendices. Also included is a guide on where to obtain additional information for treatment, referral, and follow-up for diseases with possible environmental and/or occupational origins.
