Yushchenko poisoning 'second highest ever'

New tests reveal the level of dioxin poison in the blood of Ukrainian presidential candidate Victor Yushchenko is more than 6,000 times higher than normal, according to the expert analysing the samples.

The concentration, about 100,000 units per gram of blood fat, is the second highest ever recorded in human history, 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.
