Are our government’s assumptions about the dangers of dioxin all wrong?  Maybe so, after an international team of researchers concluded that humans eliminate traces of dioxin from their bodies much faster than previously thought.  The researchers from Montreal, Milan, and the CDC studied blood samples from a select group of workers who had very high dioxin exposure decades ago.  They found that their actual exposure may have been underestimated by a factor of 10 times or more.  Since this means dioxin’s cancer potency was overestimated by a similar amount, and is the cornerstone of the EPA’s current assessment, this could have far reaching impacts on dioxin’s regulation.
