DEFOLIANT
USED BY U.S. MILITARY 1961-1971 in Vietnam war
MIXTURE 1:1 OF TWO HERBICIDES 2,4,5-T AND 2,4D
Manufactured for the U.S. Department of Defense
primarily by MOSANTO CORPORATION and DOW
CHEMICAL
The 2,4,5-T used to produce Agent Orange was
contaminated with 2,3,7,8-tetrachlorodibenzodioxin
(TCDD) , an extremely toxic dioxin compound
 1:1 MIXTURE OF TWO PHENOXYL HERBICIDES
 2,4-Dichlorophenoxyacetic acid(2,4-D)
 2,4,5-Trichlorophenoxyacetic acid (also known as
2,4,5-T)
 2,4,5-T was contaminated with a dioxin, 2,3,7,8-
Tetrachlorodibenzodioxin (TCDD)
 TCDD has been described as "perhaps the most toxic
molecule ever synthesized by man".
 The National Toxicology Program has classified TCDD
as "known to be a human CARCINORGEN”
 The half-life of dioxins in soil is more than 10 years,
and TCDD in human fat tissue is about 7 years.
 the United States military sprayed nearly 20,000,000
U.S. gallons (75,700,000 l)
 the goal was to defoliate rural/forested land
 12 percent of the total area of South Vietnam had been
sprayed
 TCDD concentrations in soil and water were hundreds
of times greater than the levels considered safe by the
U.S. Environmental Protection Agency
 4 million citizens were exposed, about 3 million have
suffered illnesses
 Children in the areas have multiple health problems:
including cleft palate, mental disabilities, hernias, and
extra fingers and toes,
 High levels of dioxin were found in the breast milk of
South Vietnamese women
 The contaminated soil and sediment poisoning food
chain and causing illnesses, serious skin diseases and a
variety of cancers in the lungs, larynx, and prostate
 the veterans were told not to worry, and were
persuaded the chemical was harmless.
 high levels of dioxin in the blood of U.S. military
 rates of cancer, and nerve, digestive, skin, and
respiratory disorders have increased.
 had higher rates of throat cancer, acute/chronic
leukemia, Hodgkin's lymphoma and non-Hodgkin's
lymphoma, prostate cancer, lung cancer, colon cancer,
soft tissue sarcoma and liver cancer.
 Use Veterans began to file claims in 1977 to the
Department of Veterans Affairs => claims were denied
 From 1978, several lawsuits have been filed against the
companies which produced Agent Orange
 Vietnam Association for Victims of Agent
Orange/dioxin (VAVA), filed a lawsuit judges
dismissed the case
