"Industries Fight EPA Study Linking Dioxin to Cancer" (April 12) highlights the Bush administration's new attitude toward public health. The report, compiled at the behest of the chemical industry, attempts to quantify dangers associated with dioxin. But when evidence mounted that extremely low doses of dioxin have been known to cause cancer and reproductive and developmental effects in animals, industry became displeased. In fact, one form of dioxin, TCDD, was found to be among the world's most potent toxins.

New tests reveal that Ukrainian presidential candidate Viktor Yushchenko's blood contains the second-highest level of dioxin poisoning ever recorded in a human -- more than 6,000 times the normal concentration, the expert analyzing the samples said. Abraham Brouwer, professor of environmental toxicology at the Free University in Amsterdam, where the blood samples were sent for analysis, said they contained about 100,000 units of dioxin per gram of blood fat.

Conveniently, these novel approaches to the evaluation of health risk just happen to change the numbers enough so that the EPA feels justified in not taking the protective actions that would otherwise be required by law.
