Agent Orange was the nickname given to a powerful herbicide and defoliant used by the U.S. military in its Herbicidal Warfare program during the Vietnam War. Agent Orange was used from 1961 to 1971, and was by far the most used of the so-called "rainbow herbicides" used during the program. Agent Orange (as well as Agents Purple, Pink, Blue, White, and Green) contained dioxins which are alleged to have caused harm to the health of those exposed during the Vietnam War. Studies of populations highly exposed to dioxin indicate increased risk of various types of cancer; the effect of long term low level exposure has not been established. Since the 1980s, several lawsuits have been filed against the companies who produced Agent Orange, among them being Dow Chemical and Monsanto. U.S. veterans obtained $180 million in compensation in 1984, while Australian, Canadian and New Zealand veterans also obtained compensation in an out-of-court settlement the same year. In 1999, 20,000 South Koreans filed a lawsuit in Korea; in January 2006, the Korean Appeal Court ordered Monsanto and Dow to pay $62 million in compensation to about 6,800 people. However, no Vietnamese have obtained compensation, and on March 10, 2005 Judge Jack Weinstein of Brooklyn Federal Court dismissed the lawsuit filed by the Vietnamese victims of Agent Orange against the chemical companies that produced the defoliants/herbicides.
It was later learned that a dioxin, 2,3,7,8-tetrachlorodibenzo-para-dioxin (TCDD), is produced as a byproduct of the manufacture of 2,4,5-T, and was thus present in any of the herbicides that used it. The National Toxicology Program has classified TCDD to be a human carcinogen, frequently associated with soft-tissue sarcoma, Non-Hodgkin's lymphoma, Hodgkin's disease and chronic lymphocytic leukemia (CLL). 2,4,5-T has since been banned for use in the US and many other countries.
The herbicide 2,4-D does not contain dioxin, and remains one of the most used herbicides in the world today.
Diseases associated with dioxin exposure are chloracne, soft tissue sarcomas, Hodgkin's disease, and non-Hodgkin's disease. Diseases with limited evidence of an association with Agent Orange are respiratory cancers, prostate cancer, multiple myeloma, Porphyria cutanea tarda (a type of skin disease), acute and subacute transient peripheral neuropathy, spina bifida, Type 2 diabetes, and acute myelogenous leukemia found only in the second or third generation. Diseases with inadequate or insufficent evidence of an association are hepatobiliary cancers, nasal or nasophargyngeal cancers, bone cancer, female reproductive cancers, renal cancer, testicular cancer, leukemia, spontaneous abortion, birth defects, neonatal or infant death and stillbirths, low birth weight, childhood cancers, abnormal sperm parameters, cognitive neuropsychiatric disorders, ataxia, peripheral nervous system disorders, circulatory disorders, respiratory disorders, skin cancers, urinary and bladder cancer. Diseases with limited or suggestive evidence of no association are gastrointestinal tumors such as stomach cancer, pancreatic cancer, colon cancer, and rectal cancer, and brain tumors.
During the Vietnam War, the US instituted a massive herbicidal program that ran from 1961 through 1971. The aim of the program was two-fold, one to destroy the "cover" provided by the jungle-like forest, and another to deny food to the enemy. First named Operation Trail Dust, then Operation Hades, it was finally renamed Operation Ranch Hand.
A variety of chemicals, fifteen in total, were tested or used operationally during this program. The primary broad-leaf herbicides sprayed during the "testing" phase of the program between 1962 and 1964 were Agent Orange, Agent Purple and Agent White. The chemicals themselves had no color; the names refer to colored stripes painted on the 55 gallon barrels to identify their contents. Much smaller amounts of other herbicides were also tested, including Agent Pink, Agent Green, Dinoxol, Trinoxol, Bromacil, Diquat, Tandex, Monuron, Diuron and Dalapon. Agent Blue was an unrelated herbicide based primarily on arsenic used to kill rice plants which were not susceptible to the phenoxy-based agents. A variety of Paraquat-related chemicals were apparently also tested in this role. For spraying, the various agents were mixed with kerosene or diesel fuel.
By 1964 the testing phase had ended, and Agent Orange was selected as the most effective agent for "territory denial". Operational use started in January 1965, increasing in breadth as logistical problems were solved. Most of Agent Orange sprayed during the program was delivered from modified US Air Force C-123K Provider aircraft under a program known as Operation Ranch Hand. Other delivery methods included helicopters, truck and hand spraying, notably for the areas directly around US bases. From 1968 on, an improved version known as "Orange II" or "Super Orange" was used as well.
Spraying reached its maximum during the most intense period of the war, between 1967 and 1968. After that the program "drew down", and ended in 1971. By this point an estimated 19 million gallons of herbicide had been sprayed on Vietnam, Cambodia and Laos, somewhat more than half (55%) of that Agent Orange, between 1962 and 1971. Early estimates from 1974 had placed the amounts lower, between 12 and 14 million US gallons (45,000 and 53,000 m³). In total about 6 million acres (24,000 km²) were sprayed in Vietnam alone.
The National Academy of Sciences undertook a survey of the scientific literature on the health effects of dioxin exposure, listing a number of health effects associated with significant exposure. The study is updated every two years.
On March 10, 2005, the District Court judge Jack Weinstein - who had defended the US veterans victims of Agent Orange - dismissed the suit, ruling that there was no legal basis for the plaintiffs' claims. The judge concluded that Agent Orange was not considered a poison under international law at the time of its use by the US; that the US was not prohibited from using it as an herbicide; and that the companies which produced the substance were not liable for the method of its use by the government. The US government, is not a party in the lawsuit claiming sovereign immunity.
On September 30, 2005, the Vietnamese victims lodged an appeal in the Second Circuit Court of Appeals; it is expected that the Court of Appeals will hold an oral argument sometime in Fall 2006. At this point the appeal is focused on whether or not the case will be reinstated and go to trial.
In order to assist those who have been impacted by Agent Orange/Dioxin, the Vietnamese have established "Peace villages", which each host between 50 to 100 victims, giving them medical and psychological help. As of 2006, they were 11 such Peace villages, thus granting some social protection to fewer than a thousand victims. US veterans of the war in Vietnam, NGOs and individuals who are aware and symphathetic to the impacts of Agent Orange have also supported these programs in Vietnam. An international group of Veterans from the US and its allies during the Vietnam war working together with their former enemy - veterans from the Vietnam Veterans Association - established the Vietnam Friendship Village* located outside of Hanoi. The center provides medical care, rehabilitation and vocational training for children and veterans from Vietnam who have been impacted by Agent Orange.
The US Veterans Administration has listed prostate cancer, respiratory cancers, multiple myeloma, type II diabetes, Hodgkin’s disease, non-Hodgkin’s lymphoma, soft tissue sarcoma, chloracne, porphyria cutanea tarda, peripheral neuropathy, and spina bifida in children of veterans exposed to Agent Orange as side effects of the herbicide.
For example: the songs "Orange Crush" by R.E.M, Anti-Flag's "Die for your Government" and "Depleted Uranium is a War Crime", Rage Against the Machine's "Sleep Now In The Fire", Oysterhead's "Shadow of a Man"; the album Agent Orange from German thrash metal band Sodom; the punk band Agent Orange. A Filipino band named Slapshock also wrote a song entitled "Agent Orange," though the lyrics have no connection to the herbicide.
In a Season One episode of The X-Files entitled 'E.B.E', a group known as the Lone Gunmen refer to shells coated in Depleted Uranium as 'the Agent Orange of the 90s'.
In his stand-up routine, the British comedian Jack Dee has referred to an estate agent wearing excessive amounts of aftershave lotion as "Estate Agent Orange" because of the irritating effect on his eyes.
