Agent Orange was an herbicide used in Vietnam to kill plants and defoliate trees where enemy troops hid. The name is derived from the orange stripe on the drums in which it was stored. Herbicides were color-coded in Vietnam. Agent Orange was a mixture of chemicals containing 2,4-D and 2,4,5-T (which contained dioxin or TCDD). This defoliant was utilized in Vietnam between 1965-1970. Republic of Korea troops also used Agent Orange in 1968-1969.
Before 1965, Agents Purple (2,4-D and 2,4,5-T) and Pink (2,4,5-T) were sprayed in Vietnam. These highly contaminated herbicides were used in small amounts but may be responsible for a large amount of the total dioxin. By 1971 more than 3.5 million acres of South Vietnam were sprayed. About 2.5 million US veterans were exposed to Agent Orange.
Dioxin is associated with malignancies and other illnesses. Vietnam veterans who served between 1962-1975 and those who served in Korea in 1968 or 1969 were at risk for exposure to dioxin. There are tests to measure the level of dioxin in fat and blood but individual dioxin levels were determined not to be useful because of differences in metabolism, exposure to defoliants not containing TCDD, common exposures to TCDD, and measurement errors.
The Veterans’ Health Care Eligibility Reform Act of 1996,Section 102, Public Law 104-262 requires the VA to give hospital care, medical services, and nursing home care to veterans exposed to herbicides. VA pays disability compensation to Vietnam vets with disorders caused by Agent Orange.
Diseases associated with Agent Orange
The following conditions have been linked to Agent Orange and other herbicides:
- Chloracne - must occur within 1 year of exposure to Agent Orange
- Porphyria cutanea tarda -must occur within 1 year of exposure to Agent Orange
- Acute and subacute transient peripheral neuropathy -must occur within 1 year of exposure to Agent Orange and resolve within 2 years of date of onset
- Type 2 diabetes
- Cancers including chronic lymphocytic leukemia, soft tissue sarcoma (other than osteosarcoma,
chondrosarcoma, Kaposi's sarcoma, or mesothelioma) , non-Hodgkin’s lymphoma, Hodgkin’s disease, prostate cancer, multiple myeloma, and respiratory cancers affecting the larynx, bronchus, lung, and trachea.
Many of these illnesses may take 20-30 years to develop after exposure to Agent Orange.
Birth Defects
Spina bifida (excluding spina bifida occulta) , a birth defect, has also been linked to Agent Orange . Children of veterans who served in Vietnam and/or Korea may receive health care, vocational rehabilitation, and disability compensation through the VA.
Children of female veterans who have with other birth defects may also receive monetary benefits and health care.
Spina bifida and peripheral transient neuropathy continue to affect third generations.

Glossary
Chloracne: A skin condition that looks like common forms of acne seen in teenagers. The first sign may be excessive oiliness of the skin. This is accompanied or followed by numerous blackheads. In mild cases, the blackheads may be limited to the areas around the eyes extending to the temples. In more severe cases, blackheads may appear in many places, especially over the cheekbone and other facial areas, behind the ears, and along the arms.
Chronic lymphocytic leukemia: A disease that progresses slowly with increasing production of excessive numbers of white blood cells.
Diabetes mellitus: Often referred to as Type 2 diabetes; a condition characterized by high blood sugar levels resulting from the body's inability to respond properly to the hormone insulin.
Hodgkin 's disease: A malignant lymphoma characterized by progressive enlargement of the lymph nodes, liver, and spleen, and by progressive anemia.
Multiple myeloma: A cancer of specific bone marrow cells that is characterized by bone marrow tumors in various bones of the body.
Non-Hodgkin s lymphoma: A group of malignant tumors (cancers) that affect the lymph glands and other lymphatic tissue. These tumors are relatively rare compared to other types of cancer, and although survival rates have improved during the past two decades, these diseases tend to be fatal.
Peripheral neuropathy (transient acute or subacute):A nervous system condition that causes numbness, tingling, and muscle weakness. This condition affects only the peripheral nervous system, that is, only the nervous system outside the brain and spinal cord. Only the transient acute (short-term) and subacute forms of this condition (not the chronic persistent form) have been associated with herbicide exposure
Porphyria cutanea tarda: A disorder characterized by liver dysfunction and by thinning and blistering of the skin in sun-exposed areas.
Prostate cancer: Cancer of the prostate; one of the most common cancers among men.
Soft tissue sarcoma: A group of different types of malignant tumors (cancers) that arise from body tissues such as muscle, fat, blood and lymph vessels, and connective tissues (not in hard tissue such as bone or cartilage). These cancers are in the soft tissue that occurs within and between organs.
Spina bifida (in the children of Vietnam veterans): A neural tube birth defect that results from the failure of the bony portion of the spine to close properly in the developing fetus during early pregnancy.
