Agent
Orange: The Persistent Ghost from the Vietnam War
The Issue That Won't Go Away
The negative health effects, due to exposure to
Monsanto's Agent Orange, have been well documented over the past three
decades. The dioxin in Agent Orange has been accepted internationally as one
of the most toxic chemicals on the planet, causing everything from severe
birth defects, to cancer, to neurological disorders, to death. But Monsanto
has successfully blocked any major movement towards compensating veterans
and civilians who were exposed to the company's Agent Orange.
Long before Agent Orange was used as a herbicide in
the Vietnam war, Monsanto knew of its negative health impacts on humans.
Since then, Monsanto has been unsuccessful at covering its tracks and has
even been convicted of fabricating false research documentation that claims
Agent Orange has no negative health effects, other than a possible skin
rash. Thanks to Monsanto's influence, the Center for Disease Control also
released a report claiming veterans were never exposed to harmful levels of
Agent Orange.
As a note, from 1962 to 1970, the US military sprayed
72 million liters of herbicides, mostly Agent Orange, on over one million
Vietnamese civilians and over 100,000 U.S. troops. As a result, within ten
years of the close of the war, 9170 veterans had filed claims for
disabilities caused by Agent Orange. The VA denied compensation to 7709,
saying that a facial rash was the only disease associated with exposure.
In 2002, Vietnam requested assistance in dealing with
the tens of thousands of birth defects due to Agent Orange. In order to
avoid medical compensation expenses, Monsanto continues to claim this now
banned chemical is not toxic.

"TCDD (dioxin) has been shown to be extremely
toxic to a number of animal species. Mortality does not occur immediately.it
appears that the animals' environment suddenly becomes toxic to them."
Casarett and Doull's Toxicology, 1996
From 1962 to 1970, the US military sprayed 72 million
liters of herbicides, mostly Agent Orange, in Vietnam. Over one million
Vietnamese were exposed to the spraying, as well as over 100,000 Americans
and allied troops. Dr. James Clary, a scientist at the Chemical Weapons
Branch, Eglin Air Force Base, who designed the herbicide spray tank and
wrote a 1979 report on Operation Ranch Hand (the name of the spraying
program), told Senator Daschle in 1988,
"When we (military scientists) initiated the
herbicide program in the 1960s, we were aware of the potential for damage
due to dioxin contamination in the herbicide. We were even aware that the
'military' formulation had a higher dioxin concentration than the 'civilian'
version due to the lower cost and speed of manufacture. However, because the
material was to be used on the 'enemy,' none of us were overly concerned. We
never considered a scenario in which our own personnel would become
contaminated with the herbicide."
Quoted by Admiral Elmo R. Zumwalt, 1990
What Did We Know About Dioxin, and When Did We Know
It?
The first reported industrial dioxin poisoning
occurred in Nitro, West Virginia in 1949. The exposed workers complained of
rash, nausea, headaches, muscle aches, fatigue and emotional instability. A
1953 accident elsewhere resulted in peripheral neuropathies.
A 1969 report commissioned by the USDA found Agent
Orange showed a "significant potential to increase birth defects."
The same year, the NIH confirmed that it caused malformations and
stillbirths in mice. In 1970, the US Surgeon General warned it might be
hazardous to "our health." The same day, the Secretaries of the
Departments of Agriculture, the Interior, and HEW jointly announced the
suspension of its use around lakes, recreation areas, homes and crops
intended for human consumption. DOD simultaneously announced its suspension
of all uses of Agent Orange.
When dioxin contaminated material spread on a Missouri
farm in 1971, hundreds of birds, 11 cats, 4 dogs and 43 horses died.
In 1978 the EPA suspended spraying Agent Orange in
national forests, due to increases in miscarriages in women living near
forests that had been sprayed.
A 1979 study published in the JAMA by Bogen et al
looked at 78 Vietnam veterans who reported Agent Orange exposures. Eighty
percent reported extreme fatigue. Over 60% had peripheral neuropathies, 73%
had depression, and 8% had attempted suicide. Forty-five per cent reported
violent rages. Sudden lapses of memory were seen in 21%.
A 1981 study by Pazderova et al. found one half of 80
exposed workers had metabolic disturbances, 23% peripheral neuropathies, and
the majority, psychiatric changes, primarily depression and fatigue.
In 1979, 47 railroad workers were exposed to PCBs
including dioxin in Missouri when cleaning up a spillage from a damaged tank
car that had been filled with these chemicals. All were followed medically
for six years. Their initial complaints included fatigue and muscle aches.
Two committed suicide. Careful evaluations at Rush-Presbyterian Hospital, in
Chicago, confirmed peripheral neuropathies (in 96%), depression (69%),
tremors (78%), abnormal fatigue (91%), and muscle aches or cramp (51%). Half
had cognitive problems, including problems with attention and concentration
(50%) and slowed reaction times.
These studies are all consistent with each other, and
describe a very significant, multi-system illness affecting all parts of the
nervous system, and causing fatigue and muscle aches. Some of the studies
documented additional organ dysfunction. This syndrome could be very
disabling.
What Did It Take to Forget What We Knew?
By 1983, 9170 veterans had filed claims for
disabilities that they said were caused by Agent Orange. The VA denied
compensation to 7709, saying that a facial rash was the only disease
associated with exposure.
Congress passed the Veterans' Dioxin and Radiation
Exposure Compensation Standards Act of 1984 in response. It required the VA
to appoint a 'Veterans' Advisory Committee on Environmental Hazards' to
review the literature on dioxin and submit recommendations to the head of
the VA.
According to Admiral Elmo Zumwalt, "The
VA.directly contradicted its own established practice, promulgating instead
the more stringent requirement that compensation depends on establishing a
cause and effect relationship," improperly denying the bulk of the
claims.
Four groups of impartial scientists were asked by
Zumwalt to review the Advisory Committee transcripts. Their comments are
telling, and include the following:
"The work of the Advisory Committee.has little or
no scientific merit."
".an inadequate process is being used to evaluate
scientific publications for use in public policy."
".less than objective."
Unfortunately, the flawed scientific reviews didn't
end with the VA committee. The CDC was brought in to add weight to the bogus
analysis of dioxin's effects. After 4 years and $63 million in federal
funds, CDC concluded that an Agent Orange study could not be done based on
military records, and furthermore concluded, without data, that veterans
were never exposed to harmful doses of Agent Orange!
When the CDC's protocols were examined, however, it
was found that three changes had been made to its study in 1985, in an
apparent attempt to dilute any negative effect that might be found. Congress
learned in 1986 that administration officials, not scientists, had
forestalled CDC research on the effects of dioxin.
In 1990, Senator Daschle disclosed additional
political interference in the Air Force's Ranch Hand study of Agent Orange
effects. A 1984 draft report's conclusion was substantially altered, and the
study was described as "reassuring."
The Ranch Hand study is still ongoing, despite new
allegations of fraudulent methodologies coming to light every few years. It
will cost taxpayers over $100 million.
Monsanto, a manufacturer of Agent Orange, was happy to
duplicate the methods of federally funded studies. By omitting five deaths
in the exposed group and putting four exposed workers in the control group,
they were able to hide a 65% higher death rate in the workers exposed at the
Nitro plant. Another study of workers exposed in 1953 at a BASF plant was
also shown to be falsified, as all the data had been supplied by the BASF
company.
Thanks to the efforts of Admiral Zumwalt, who as the
commanding Navy Admiral in Vietnam was responsible for some of the spraying,
and whose son died from lymphoma, probably as a result of dioxin exposure,
many more illnesses were finally linked to Agent Orange, and have been made
service-connectable over the past decade.
But Zumwalt did not succeed at clearing the air
regarding dioxin's actual toxicity, nor did he stop further scientific
shenanigans carried out by government and industry to hide the toxic effects
of other products, especially those to which our servicemen and women are
exposed.
In April 2000, the National Institute for
Environmental Health Sciences tried to release a report listing dioxin as a
carcinogen, but it was blocked by a lawsuit filed by an industry group.
NIEHS had tried to list dioxin as a carcinogen in 1991, but was not allowed
to do so then. John Bucher, deputy director of the NIEHS, says, "Dioxin
tends to increase the likelihood of all types of cancers" while
industry representatives continue to claim there is insufficient evidence to
link dioxin to health problems.
Ellen Silbergeld, a University of Maryland
toxicologist, responded, "I think the public should be mad as hell
about the [dioxin review] process and the way it's been abused."
Agent Orange: 2002
US and Vietnamese government scientists and
international experts met last week in Hanoi to discuss the effects of the
"last significant ghost" of the Vietnam War: Agent Orange.
Vietnam wants US help performing research and
obtaining compensation. It blames Agent Orange for tens of thousands of
birth defects. The US and Vietnam did sign an agreement during the meeting
to carry out joint research studies. But US ambassador Raymond Burghardt
noted that developing research studies "that are definitive and address
the underlying causes of disease in Vietnam" will be a "difficult
task."
Reporting on the conference, Reuters pointed out,
"Observers say conclusive research could have far-reaching and
expensive consequences in terms of compensation claims for the US and Agent
Orange makers, Dow Chemical and Monsanto."
However, the US seems to think it has an ace in the
hole. The US embassy made clear, at the time of the conference, that
"US-Vietnam relations were normalized in 1995 after Vietnam dropped
claims of war reparations/compensation. At the time of normalization,
neither compensation nor reparations were granted or contemplated for the
future."
And, anyway, the US government has a fallback
position. "Washington argues there is no hard evidence showing the
defoliant caused specific illness," Reuters reported last week. And US
government scientists chimed in that any linkages to birth defects
"would take many more years to prove."
The well-documented story of dioxin and scientific
perfidy provide a guidepost for how to assess government-sponsored research,
advisory committees, and regulatory decisions that impact on the health
effects of toxic exposures, especially when the government may be liable for
damages.

Condemned to Repeat It"
