The concentration, about 100,000 units per gram of blood fat, is the second highest ever recorded, said Abraham Brouwer, professor of environmental toxicology at the Free University in Amsterdam, where blood samples taken last weekend in Vienna were sent for analysis.A normal level of dioxin is between 15 and 45 units. Almost everyone has some level of dioxins because the toxic chemical is widespread in the environment — mainly from its industrial usages — and accumulates in the food chain. In the case of Yushchenko, Brouwer's team has narrowed the search from more than 400 dioxins to about 29 and is confident they will identify the poison by week's end. That, in turn, could provide clues for the investigation of the alleged poisoning. "From a (chemical) fingerprint, at least you can deduce what kind of sources might have been involved," Brouwer told The Associated Press. "The labs will ... try to find out whether it matches any of the batches of dioxins that are around, so that maybe you can trace it back to where it was ordered or where it came from."
Experts say Yushchenko, whose face has been pockmarked and disfigured, has probably experienced the worst effects already and should gradually recover, with no impairment to his working ability. ...
