Yushchenko Poisoned by Most Toxic Form of Dioxin
Blood tests show that Ukrainian opposition presidential candidate Viktor Yushchenko was poisoned with the most toxic form of dioxin, known as TCDD, the scientist who performed the tests said Friday (see GSN, Dec. 13). Tests showed that Yushchenko was poisoned with pure TCDD, according to Abraham Brouwer, an environmental toxicology professor at the Free University in Amsterdam. “It is a single chemical, not a mix,” Brouwer said. “This tells us ... there is no way it occurred naturally, because it is so pure.” “There were some small signals in the test that may tell us something about where it was ... made,” Brouwer added. Testing also found that Yushchenko’s blood contained 100,000 units of dioxin — the second highest amount ever recorded, according to the Associated Press. Manufacturing processes that use chlorine, including paper and pulp bleaching, produce TCDD as a byproduct, according to the Associated Press. The purity of the poison indicates it could have only come from one of three sources — a government biological or chemical weapons facility, a research laboratory or a “clever chemist,” said dioxin expert Arnold Schecter, a professor of environmental sciences at the University of Texas School of Public Health in Dallas (Emma Ross, Associated Press/Yahoo!News, Dec. 17).
