Dioxin, are we at risk?

70 minutes.  That's all it takes to listen to the EPA's concerns about the risks of dioxins to human health.   It's time well invested.  Recorded in 43, 1-3 minute segments.  If you do not have 70 minutes to spare, listen to a few segments a day. 

"Dioxin has been called one of the most dangerous chemicals ever known. Purging uncertainties and clarifying myths about dioxin, Dr. Birnbaum will discuss dioxin in generalwhere it comes from, how we interact with itand specifically, its staggering impact on human health. She will also talk about dioxin effects in the Great Lakes. "   Local Motion

Dr. Linda Birnbaum is a world renowned expert on the human health effects of dioxin.   The audio content presented below are excerpts from the LocalMotion video "Dioxin, are we at risk?" as presented by Dr. Birnbaum  during the " Toxic Chemicals in the Great Lakes Basin" seminar December 2001.    In 2001, Dr. Birnbaum was the EPA's Director of Human Studies Division, National Health & Environmental Effects Research Lab.
