US veterans' groups and Vietnamese groups, including the Vietnamese government, have convened scientific studies to explore their belief that dioxins were responsible for a host of disorders, including tens of thousands of birth defects in children, amongst Vietnam veterans as well as an estimated one million Vietnamese, through their exposure to Agent Orange during the Vietnam War, which was found to be highly contaminated with TCDD. The most recent study, paid for by the National Academy of Sciences, was released in an April 2003 report.
The Center for Disease Control found that dioxin levels in Vietnam veterans [4] were in no way atypical when compared against the rest of the population. The only exception existed for those who directly handled Agent Orange. These were members of Operation Ranch Hand. Long term studies of the members of Ranch Hand have thus far uncovered a possibility of elevated risks of diabetes.
