🛈 Synopsis : Air Force reservists who worked after Vietnam War in C-123 aircraft that sprayed Agent Orange could have experienced health effects from exposure to the herbicide.

Main Digest

Air Force reservists based in the U.S. who worked after the Vietnam War in C-123 aircraft that sprayed Agent Orange during the war could have experienced adverse health effects from exposure to the herbicide, says a new report from the Institute of Medicine. The reservists who served in the contaminated C-123s experienced some degree of exposure to the toxic chemical component of Agent Orange known as TCDD (2,3,7,8-tetrachlorodibenzo-p-dioxin), and it is plausible, in some cases, that the reservists exceeded TCDD exposure guidelines for workers in enclosed settings.

After their use in Vietnam, 24 C-123 aircraft were added to the fleets of four U.S. Air Force reserve units for use in military airlifts and medical and cargo transport. From 1972 to 1982, approximately 1,500 to 2,100 U.S. Air Force Reserve personnel trained and worked aboard these C-123 aircraft.

After becoming aware that these aircraft had previously sprayed Agent Orange, some Air Force Reservists applied to the U.S. Department of Veterans Affairs for compensatory coverage under the Agent Orange Act of 1991 (AO Act), which provides health care and disability coverage for health conditions that have been deemed presumptively service-related and due to herbicide exposure during the Vietnam War. The VA denied the applications on the basis that these reservists were ineligible, because without "boots on the ground" service in Vietnam, they were not covered under the AO Act. However, with knowledge that some air and surface samples from the C-123s taken between 1979 and 2009 showed the presence of Agent Orange residues, representatives of the C-123 Veterans Association began an effort to reverse the VA's position and obtain coverage. The VA asked the IOM to evaluate whether working in the C-123s could have plausibly resulted in exposures detrimental to the health of the Air Force reservists. The IOM was not directed to make any policy determinations concerning the applicability of the AO Act to the group.

The committee that carried out the study and wrote the report examined the results of air and surface sampling for TCDD and herbicides conducted between 1979 and 2009 in three C-123 aircraft and only herbicide results from an additional 10 C-123s. The committee determined that the length of time between the spraying in Vietnam and the TCDD sampling, few sampling data, and minimal information about the reservists' activities on the airplanes made it impossible to accurately estimate the level of TCDD exposure the reservists had experienced. However, because TCDD residues had been detected on interior surfaces of the aircraft, the committee stated with confidence that the reservists were exposed to TCDD to some extent when working in the C-123s. All the relevant samples, which were collected many years after the reservists worked in the planes, fall in or above the range specified as meriting cautionary consideration by international exposure guidelines. Therefore, the committee found it plausible that some of the reservists had problematic increases in their risks of experiencing a variety of adverse health outcomes.

"Detection of TCDD so long after the Air Force reservists worked in the aircraft means that the levels at the time of their exposure would have been at least as high as the taken measurements, and quite possibly, considerably higher," said committee chair Robert Herrick, a senior lecturer on occupational hygiene at the Harvard School of Public Health in Cambridge, Mass.

The committee noted that efforts to recover work records concerning the reservists' use of C-123s have been unsuccessful. Therefore, it is unlikely that any additional information will be become available to establish more definitively the magnitude of exposures experienced by the reservists.

The study was sponsored by the U.S. Department of Veterans Affairs.

Update: VA Continues to Deny Justice To C-123 Crews Exposed to Dioxin - by Vietnam Veterans of America (March 23, 2015)

"It is an outrage that the VA, in effect, is continuing to deny these veterans justice," said John Rowan, National President of Vietnam Veterans of America. "These VA bureaucrats attempting to delay justice ought to be relieved of their duties so that they can no longer abuse veterans with their tactic of 'delay, deny, until they die.' There is no excuse for why these worthy veterans are still not being treated with the appreciation and the respect their service warrants." Rowan praised Wes Carter, the leader of the C-123 Veterans Association, for his spunk and spirit: "You've got to keep on keeping on," Rowan urged, "and VVA will be at your side to convince the VA hierarchy that to continue to delay justice is to deny justice."

For over five years, retired Air Force Reserve Major Wes Carter has led the fight of his life: to get the Department of Veterans Affairs to acknowledge that the C-123 Provider military cargo planes which transported Agent Orange to and from Vietnam had, in fact, been contaminated with dioxin. A number of reputable scientists and epidemiologists at federal agencies have gone on record, endorsing Carter's stance that these craft remained hazardous to the health of the 2,100 crew members, flight nurses, and maintenance workers who serviced them between 1972 and 1982. "Yet the VA, in all its wisdom, maintained that these men and women who had been exposed to Agent Orange ought not be eligible to receive the same healthcare and disability compensation benefits that boots-on-the-ground veterans of Vietnam receive," Rowan noted.

"VVA has long supported Major Carter in his quest for justice," Rowan said. "When the Institute of Medicine (IOM) concluded, in a study funded by the VA, that the planes were actively contaminated when Air Force Reservists flew them, we were as pleased as Wes Carter, who exulted, 'We won!' The IOM report was released in January 2015, yet Major Carter and those who have been sickened with maladies the VA concedes are associated with exposure to Agent Orange have still not received the justice they deserve. Why? Because a few bad actors in the office of Public Health & Environmental Hazards at the VA continue their attempts to delay justice despite the conclusive report by the IOM."
