MORE DIOXIN DELAYS.

The article reports on the move of U.S. Environmental Protection Agency (EPA) Administrator Lisa P. Jackson to direct her organization to complete is reassessment of the risks from the most potent form of dioxin by the end of 2010. However, the article notes that the agency may miss the deadline as a panel of scientific reviewers from outside the agency says more work should be done on the most recent draft version of the reassessment. It adds that 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) is the most toxic of the dioxins and carcinogenic to humans.
