Abraham Brouwer, professor of environmental toxicology at the Free University in Amsterdam, told the AP news agency that TCDD is a key ingredient of Agent Orange, a herbicide sprayed by the U.S. military during the war in Vietnam.
The tests, conducted by Brouwer, also confirmed that Yushchenko's blood contained 100,000 units of dioxin, the second-highest concentration ever recorded of TCDD in a human being.
Yushchenko became violently ill during the campaign for the presidency back in September, with his face later breaking out in severe acne and lesions that are a trademark feature of dioxin poisoning.
Yushchenko faces Kremlin-backed Viktor Yanukovych in a repeat of the second round of the presidential election on 26 December.
Today, the candidates are conducting overlapping campaign trips to the eastern industrial city of Kharkiv.
