Dioxins have been called the most toxic of all man-made chemicals, based on animal studies that show effects at extremely low doses – in the parts per trillion.Nevertheless, the EPA said that people's exposures have declined so much in the past two decades that most people are safe. "Today’s findings show that generally, over a person’s lifetime, current exposure to dioxins does not pose a significant health risk," EPA officials said.
One scientist who studies dioxins, Arnold Schecter of University of Texas School of Public Health, questioned that statement, calling it "very odd," because some people are more highly exposed than average and some groups, such as fetuses and nursing babies, are more sensitive to the effects.
