Many experts at the time, including Arthur Galston, opposed herbicidal warfare due to concerns about the side effects to humans and the environment by indiscriminately spraying the chemical over a wide area. defeated most of the resolutions, arguing that Agent Orange was not a chemical or a biological weapon as it was considered a herbicide and a defoliant and it was used in effort to destroy plant crops and to deprive the enemy of concealment and not meant to target human beings. The most affected zones are the mountainous area along Truong Son (Long Mountains) and the border between Vietnam and Cambodia.
As early as 1966, resolutions were introduced to the United Nations charging that the U. was violating the 1925 Geneva Protocol, which regulated the use of chemical and biological weapons. The affected residents are living in substandard conditions with many genetic diseases.
With the exception of liver cancer, these are the same conditions the U. Veterans Administration has determined may be associated with exposure to Agent Orange/dioxin, and are on the list of conditions eligible for compensation and treatment.
If not bound chemically to a biological surface such as soil, leaves or grass, Agent Orange dries quickly after spraying and breaks down within hours to days when exposed to sunlight and is no longer harmful. Dioxin enters the body by attaching to a protein called the aryl hydrocarbon receptor (Ah R), a transcription factor.
Up to four million people in Vietnam were exposed to the defoliant.
The government of Vietnam says as many as 3 million people have suffered illnesses because of Agent Orange. government has documented higher cases of leukemia, Hodgkin's lymphoma, and various kinds of cancer in exposed veterans.
Several publications by the Public Health Service have shown that veterans have increased rates of cancer, and nerve, digestive, skin, and respiratory disorders.
The Center for Disease Control and Prevention notes that in particular, there are higher rates of acute/chronic leukemia, Hodgkin's lymphoma and non-Hodgkin's lymphoma, throat cancer, prostate cancer, lung cancer, colon cancer, Ischemic heart disease, soft tissue sarcoma and liver cancer.
