Book Description
The Vietnam war of 1961-1975 is, among other things, notable for the massive employment of anti-plant chemical warfare agents (herbicides or plant defoliating and killing chemicals). Primarily during the mid to late 1960's the USA sprayed approximately 72 million liters of these herbicides over some 1.7 million hectares of rural South Vietnam; that is about one hectare in every ten. At least 12% of the forests of South Vietnam were sprayed one or more times as were 5% or more of the agricultural land.The "International Symposium on Herbicides and Defoliants in War: The Long-term Effects of Man and Nature" was convened in Ho Chi Minh City from January 14 to 19, 1983 in order to examine the aftermath of this chemical assault on South Vietnam, after about a decade had elapsed since the spraying. More than 70 ecological and medical scientists from some 20 countries, both East and West, came together in order to meet with about an equal number of their Vietnamese counterparts. The international participants included some of the top experts in the world in their respective fields of ecological and medical science. It was strictly a working conference open only to qualified scientists.This is the final summary report of the symposium and the seven final summary reports of the various working groups, plus an article compiled from papers presented by participating Vietnamese scientists.

Book Description
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.

Book Description
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.

Book Description
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.

Book Description
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 Description
As the public increasingly questioned the war in Vietnam, a group of American scientists deeply concerned about the use of Agent Orange and other herbicides started a movement to ban what they called “ecocide.” David Zierler traces this movement, starting in the 1940s, when weed killer was developed in agricultural circles and theories of counterinsurgency were studied by the military. These two trajectories converged in 1961 with Operation Ranch Hand, the joint U.S.-South Vietnamese mission to use herbicidal warfare as a means to defoliate large areas of enemy territory. Driven by the idea that humans were altering the world's ecology for the worse, a group of scientists relentlessly challenged Pentagon assurances of safety, citing possible long-term environmental and health effects. It wasn't until 1970 that the scientists gained access to sprayed zones confirming that a major ecological disaster had occurred. Their findings convinced the U.S. government to renounce first use of herbicides in future wars and, Zierler argues, fundamentally reoriented thinking about warfare and environmental security in the next forty years. Incorporating in-depth interviews, unique archival collections, and recently declassified national security documents, Zierler examines the movement to ban ecocide as it played out amid the rise of a global environmental consciousness and growing disillusionment with the containment policies of the cold war era.
