Available in PDF, EPUB and Kindle. Book excerpt: This book originated in a series of cross-disciplinary conversations in the years 1984-1990 between the editor, who is a physician-researcher involved in clinical and laboratory research, and a dioxin toxicologist. During the years in which the conversations took place, an extraordinary amount of new scientific literature was published related to dioxins, defined for purposes of this text as the chlorinated dibenzo-p-dioxins, dibenzofurans, polychlorinated biphe nyls (PCB's) and other compounds that are structurally and toxicologically similar to 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7 ,8-TCDD), the most extensively studied and most toxic of this group of chemicals. Dioxins also began to interest not only chemists and toxicologists, but also specialists from diverse disciplines such as wildlife and environmental science, immunology, neuroscience,public health, epidemiology, med icine, government, law, sociology, and journalism. Specialists from such varied disciplines, while familiar with their own literature, frequently did not have time to follow the dioxin literature outside their specialty area. In addition, each specialty had unique knowledge, methods, and perspectives. Cross disciplinary conversation was necessary, but all too frequently, specialists from the various disciplines did not speak the same language, resulting in misunderstanding.

This book was released on 1995-05-12 with total page 988 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.
Download or read book Post Vietnam Dioxin Exposure in Agent Orange Contaminated C 123 Aircraft written by Institute of Medicine and published by National Academies Press. This book was released on 2015-05-20 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 1972 to 1982, approximately 1,500-2,100 US Air Force Reserve personnel trained and worked on C-123 aircraft that had formerly been used to spray herbicides in Vietnam as part of Operation Ranch Hand. After becoming aware that some of the aircraft on which they had worked had previously served this purpose, some of these AF Reservists applied to the US Department of Veterans Affairs (VA) for compensatory coverage under the Agent Orange Act of 1991. The Act provides health care and disability coverage for health conditions that have been deemed presumptively service-related for herbicide exposure during the Vietnam War. The VA denied the applications on the basis that these veterans were ineligible because as non-Vietnam-era veterans or as Vietnam-era veterans without "boots on the ground" service in Vietnam, they were not covered. However, with the knowledge that some air and wipe samples taken between 1979 and 2009 from some of the C-123s used in Operation Ranch Hand showed the presence of agent orange residues, representatives of the C-123 Veterans Association began a concerted effort to reverse VA's position and obtain coverage. At the request of the VA, Post-Vietnam Dioxin Exposure in Agent Orange-Contaminated C-123 Aircraft evaluates whether or not service in these C-123s could have plausibly resulted in exposures detrimental to the health of these Air Force Reservists. The Institute of Medicine assembled an expert committee to address this question qualitatively, but in a scientific and evidence-based fashion. This report evaluates the reliability of the available information for establishing exposure and addresses and places in context whether any documented residues represent potentially harmful exposure by characterizing the amounts available and the degree to which absorption might be expected. Post-Vietnam Dioxin Exposure rejects the idea that the dioxin residues detected on interior surfaces of the C-123s were immobile and effectively inaccessible to the Reservists as a source of exposure. Accordingly, this report states with confidence that the Air Force Reservists were exposed when working in the Operation Ranch Hand C-123s and so experienced some increase in their risk of a variety of adverse responses.

This book was released on 1994-01-15 with total page 791 pages. Available in PDF, EPUB and Kindle. Book excerpt: Have U.S. military personnel experienced health problems from being exposed to Agent Orange, its dioxin contaminants, and other herbicides used in Vietnam? This definitive volume summarizes the strength of the evidence associating exposure during Vietnam service with cancer and other health effects and presents conclusions from an expert panel. Veterans and Agent Orange provides a historical review of the issue, examines studies of populations, in addition to Vietnam veterans, environmentally and occupationally exposed to herbicides and dioxin, and discusses problems in study methodology. The core of the book presents What is known about the toxicology of the herbicides used in greatest quantities in Vietnam. What is known about assessing exposure to herbicides and dioxin. What can be determined from the wide range of epidemiological studies conducted by different authorities. What is known about the relationship between exposure to herbicides and dioxin, and cancer, reproductive effects, neurobehavioral disorders, and other health effects. The book describes research areas of continuing concern and offers recommendations for further research on the health effects of Agent Orange exposure among Vietnam veterans. This volume will be critically important to both policymakers and physicians in the federal government, Vietnam veterans and their families, veterans organizations, researchers, and health professionals.
Download or read book Long Term Health Consequences of Exposure to Burn Pits in Iraq and Afghanistan written by Institute of Medicine and published by National Academies Press. This book was released on 2011-10-31 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many veterans returning from the conflicts in Iraq and Afghanistan have health problems they believe are related to their exposure to the smoke from the burning of waste in open-air "burn pits" on military bases. Particular controversy surrounds the burn pit used to dispose of solid waste at Joint Base Balad in Iraq, which burned up to 200 tons of waste per day in 2007. The Department of Veterans Affairs asked the IOM to form a committee to determine the long-term health effects from exposure to these burn pits. Insufficient evidence prevented the IOM committee from developing firm conclusions. This report, therefore, recommends that, along with more efficient data-gathering methods, a study be conducted that would evaluate the health status of service members from their time of deployment over many years to determine their incidence of chronic diseases.
Download or read book Veterans and Agent Orange written by National Academies of Sciences, Engineering, and Medicine and published by National Academies Press. This book was released on 2019-01-20 with total page 739 pages. Available in PDF, EPUB and Kindle. Book excerpt: From 1962 to 1971, the U.S. military sprayed herbicides over Vietnam to strip the thick jungle canopy that could conceal opposition forces, to destroy crops that those forces might depend on, and to clear tall grasses and bushes from the perimeters of US base camps and outlying fire-support bases. Mixtures of 2,4-dichlorophenoxyacetic acid (2,4-D), 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), picloram, and cacodylic acid made up the bulk of the herbicides sprayed. The main chemical mixture sprayed was Agent Orange, a 50:50 mixture of 2,4-D and 2,4,5-T. At the time of the spraying, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD), the most toxic form of dioxin, was an unintended contaminant generated during the production of 2,4,5-T and so was present in Agent Orange and some other formulations sprayed in Vietnam. Because of complaints from returning Vietnam veterans about their own health and that of their children combined with emerging toxicologic evidence of adverse effects of phenoxy herbicides and TCDD, the National Academies of Sciences, Engineering, and Medicine was asked to perform a comprehensive evaluation of scientific and medical information regarding the health effects of exposure to Agent Orange, other herbicides used in Vietnam, and the various components of those herbicides, including TCDD. Updated evaluations were conducted every two years to review newly available literature and draw conclusions from the overall evidence. Veterans and Agent Orange: Update 11 (2018) examines peer-reviewed scientific reports concerning associations between various health outcomes and exposure to TCDD and other chemicals in the herbicides used in Vietnam that were published between September 30, 2014, and December 31, 2017, and integrates this information with the previously established evidence database.

Download or read book Handbook of Eggs in Human Function written by Ronald Ross Watson and published by Brill Wageningen Academic. This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Eggs have been used as key part of the human diet for millennia. They contain a great variety of nutrients and material to sustain life and growth. The role of the egg as natural source of vitamins, proteins, fats, and other nutrients, continues to develop. Some nutrients have a controversy in benefits and risks. This controversy is the subject of several chapters in this book. Eggs have been used for decades by pharmaceutical companies as vehicles to grow viruses for vaccines. Currently, eggs are being developed to make antibodies for human use, so-called designer eggs. Eggs can also be used as vehicle to transport vitamins and minerals to humans via nutrient supplemented laying hens. These benefits are subject to commercial expansion, as well as being an active research area. This book, with summary points for each chapter, helps you to understand the role of eggs (including designer eggs) in general nutrition, health promotion and disease. It is aimed at health scientists, nutritionists, dieticians, and food industry groups.
Download or read book Decades of Dioxin written by Warren B. Crummett and published by Xlibris Corporation. This book was released on 2002 with total page 345 pages. Available in PDF, EPUB and Kindle. Book excerpt: By 1971 analytical scientists at Dow had good reason to believe that questions about "dioxin" (2,3,7,8-dibenzo-p-dioxin) had been appropriately addressed. This molecule had been identified as an unwanted trace contaminant in 2,4,5-trichlorophenol and its derivatives; synthesized and analytical standards prepared; characterized by all the known measurement techniques; and controlled in Dow products by newly developed analytical methods of confirmed integrity at levels 10 times lower than deemed necessary by Dow toxicologists. Thus we had not only fulfilled all the requirements of government agencies, we had gone the extra mile. No other product contaminant had been treated so rigorously. There was no doubt that Dow products were safe when used as directed. Once again we had proven that molecules could be successfully managed. Although there was already some noise decrying this conclusion, we were totally unprepared to weather the brouhaha which developed. "Dioxin" appeared to be a molecule that created fear and caused people to do strange (unscientific) things. Was it more than just a molecule? We now turned our attention to measuring the amount of "dioxin" in the environment. We were well prepared to develop methodology to do this. We had state-of-the-art equipment and some of the best chromatographers and mass spectroscopists in the world. We were confident we could find and measure "dioxin" (if present) in any matrix of interest at appropriate detection levels. Then we could determine how the dioxin got there and discover ways to completely control and manage the presence and movement of this molecule in the environment. This was our perception! This perception was reinforced by the merger of Dow analytical laboratories. For the first time powerful measurement tools would be under the same management as the separation systems. This created many opportunities for spectroscopists, chromatographers and instrument development folks to do extraordinary things together. The resulting laboratory, consisting of almost 200 technical people, was managed by a technical director and a technical manager. I was named technical manager, a position without a job description. We were not, however, positioned to communicate effectively with the world outside Dow. Those of us working in trace analysis had neither published much nor attended many scientific meetings outside the company. We had not honed either our writing or speaking skills. So our papers were rejected and we were seldom heard speaking. This took some years to correct as we didn't immediately recognize that we needed to have credibility with our peers in academia, government and other industry. In spite of this naivety on my part, I soon found myself serving on committees, task forces and study groups both within Dow and with government agencies in the United States and Canada. Immediately it became apparent to me that the integrity of analytical data at trace levels was a major problem. Different laboratories used different principles in the interpretation of signals. Consensus on data interpretation needed to be reached. But of even greater importance was the need to communicate with journalists. Each encounter with peers and others interested in "dioxin" became a great adventure filled with fun. Often these meetings were humorous, always challenging, sometimes testy scientists from industry always were portrayed as biased and even incompetent. So, "dioxin" appeared to cause people to do strange things. By means of anecdotal stories and essays this book attempts to convey the principal scientific and philosophical lessons learned, as well as reveal the astonishing behavior of those contributing to the frustration, agony and elation experienced by this industrial analytical chemist. Among the surprising lessons learned are: 1. Fear can create big business. 2. In a "crisis" situation, even
