This book was released on 1978 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of herbicides in South Vietnam between 1962 and 1971 was reviewed, including the nature and quantities of herbicides used, their handling and application. Emphasis was placed on Herbicide Orange, a 50:50 mixture of 2,4-dichlorophenoxyacetic acid (2,4-D) and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T), with its associated contaminant 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD). The at-risk US military population in South Vietnam was defined to establish the potential for exposure in handling and application of Herbicide Orange. The environmental fate of the phenoxy herbicides and TCDD was reviewed to evaluate the potential for human risk associated with exposure to areas previously treated with Herbicide Orange. The occupational and environmental aspects of the project to incinerate at sea 2.22 million gallons of Herbicide Orange during the summer of 1977 were summarized to assess the potential for human exposure in handling large quantities of the material. Scientific data were reviewed on incidents and episodes involving suspected poisoning of humans or animals by phenoxy herbicides or TCDD. Literature dealing with animal toxicology and the effects of human exposure to 2,4-D, 2,4,5-T and TCDD was reviewed to correlate exposures with symptomatology. (Author).

This book was released on 2009-04-21 with total page 353 pages. Available in PDF, EPUB and Kindle. Book excerpt: For almost four decades, controversy has surrounded the tactical use of herbicides in Southeast Asia by the United States military. Few environmental or occupational health issues have received the sustained international attention that has been focused on Agent Orange, the major tactical herbicide deployed in Southern Vietnam. With the opening and establishment of normal relations between the United States and the Socialist Republic of Vietnam in 1995, the time has come for a thorough re-examination of the military use of Agent Orange and other "tactical herbicides" in Southern Vietnam, and the subsequent actions that have been taking place since their use in Vietnam. The United States Department of Defense has had the major role in all military operations involving the use of tactical herbicides, including that of Agent Orange. This included the Department's purchase, shipment and tactical use of herbicides in Vietnam, its role in the disposition of Agent Orange after Vietnam, its role in conducting long-term epidemiological investigations of the men of Operation RANCH HAND, and its sponsorship of ecological and environmental fate studies. This book was commissioned by The Office of the Deputy Under Secretary of Defense (Installations and Environment) with the intent of providing documentation of the knowledge on the history, use, disposition and environmental fate of Agent Orange and its associated dioxin.

Book excerpt: This book tells the story of Agent Orange, its usage and the policies that surround it. Agent Orange contains a contaminant known as TCDD. It was the most widely used defoliant from 1965 – 1970 and became one of three major tactical herbicides used in Vietnam. More than 45 major health studies were conducted with Vietnam veterans from the United States, Australia, New Zealand, and Korea seeking a relationship between veterans’ health and TCDD. Allegations of birth defects in the families of Vietnam veterans and the Vietnamese represented a case study in propaganda and deliberate misinformation by the government of Vietnam. The Policies of the US Government implemented by Congress and the Department of Veterans Affairs (DVA) identified 17 recognized associated presumptive diseases that failed the tests of “cause and effect” and common sense. This book tells the story of Agent Orange, its usage, the health studies and those policies from a diverse range of perspectives, delving into science, statistics, history, policy and ethics. It is of interest to scholars engaged in history, political and social philosophy and ethics.

This book was released on 1979 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extract: Since 1977 Vietnam veterans have been contacting the Veterans Administration about health problems which they believe were caused by exposure to herbicides in Vietnam. Problems in identifying personnel exposed to herbicides and determining the possible health consequences of such exposure have hampered VA efforts to resolve veterans' concerns. This report recommends that the Department of Defense, with the assistance and guidance of an appropriate interagency group, conduct a survey of any long-term medical effects on military personnel who were likely to have been expsoed to herbicides in South Vietnam. It also recommends several additional actions VA and DOD should take.
Download or read book Blue Water Navy Vietnam Veterans and Agent Orange Exposure written by Institute of Medicine and published by National Academies Press. This book was released on 2011-07-01 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: Over 3 million U.S. military personnel were sent to Southeast Asia to fight in the Vietnam War. Since the end of the Vietnam War, veterans have reported numerous health effects. Herbicides used in Vietnam, in particular Agent Orange have been associated with a variety of cancers and other long term health problems from Parkinson's disease and type 2 diabetes to heart disease. Prior to 1997 laws safeguarded all service men and women deployed to Vietnam including members of the Blue Navy. Since then, the Department of Veteran Affairs (VA) has established that Vietnam veterans are automatically eligible for disability benefits should they develop any disease associated with Agent Orange exposure, however, veterans who served on deep sea vessels in Vietnam are not included. These "Blue Water Navy" veterans must prove they were exposed to Agent Orange before they can claim benefits. At the request of the VA, the Institute of Medicine (IOM) examined whether Blue Water Navy veterans had similar exposures to Agent Orange as other Vietnam veterans. Blue Water Navy Vietnam Veterans and Agent Orange Exposure comprehensively examines whether Vietnam veterans in the Blue Water Navy experienced exposures to herbicides and their contaminants by reviewing historical reports, relevant legislation, key personnel insights, and chemical analysis to resolve current debate on this issue.

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 U.S. base camps and outlying fire-support bases. In response to concerns and continuing uncertainty about the long-term health effects of the sprayed herbicides on Vietnam veterans, Veterans and Agent Orange provides a comprehensive evaluation of scientific and medical information regarding the health effects of exposure to Agent Orange and other herbicides used in Vietnam. The 2008 report is the eighth volume in this series of biennial updates. It will be of interest to policy makers and physicians in the federal government, veterans and their families, veterans' organizations, researchers, and health professionals.

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.

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.

Available in PDF, EPUB and Kindle. Book excerpt: The Chemical Scythe is the first book in a projected series to be published by Plenum Press in association with the International Disaster Institute. The aim of the series, Disaster Research in Practice, is to provide scientific and readable accounts on the most urgent areas of disaster research. It is fitting, therefore, that Dr. Hay's investigation into the nature and effects of dioxins heralds the new series. The problem of chemical hazards is one that we will have to learn to live with in future decades. Dr. Hay's book is an authoritative account of the chemistry and proven and potential effects of dioxins, and of the impli cations for safety planning. He concludes with a cautious, yet optimistic note-that indeed we can learn to live with such hazards, providing that we are prepared to understand and plan for the unexpected. The accident at Seveso in 1976 alerted the world to an imperfectly un derstood but immensely alarming environmental hazard. Public debate and argument as to the implications of dioxins and, indeed, the use of herbicides as aggressive weapons in Vietnam, rage on. And yet it is only through the painstaking research exemplified in this book that it will eventually be pos sible to promote the vital accountability on the part of industrialists and governments.

Available in PDF, EPUB and Kindle. Book excerpt: Veterans and Agent Orange: Update 2000 examines the state of the scientific evidence regarding associations between diseases and exposure to dioxin and other chemical compounds in herbicides used in Vietnam. It is the fourth in a series of comprehensive reviews of epidemiologic and toxicologic studies of the agents used as defoliants during the Vietnam War. Over forty health outcomes in veterans and their children are addressed. Among the report's conclusions is that there is sufficient evidence of a link between exposure and the development of soft-tissue sarcoma, non-Hodgkin's lymphoma, Hodgkin's disease, and chloracne in veterans. Additionally, it found that scientific studies offer "limited or suggestive" evidence of an association with other diseases in veteransâ€"including Type 2 diabetes, respiratory cancers, prostate cancer, multiple myeloma and some forms of transient peripheral neuropathyâ€"as well as the congenital birth defect spina bifida in veterans' children.
