Theo Colborn, an environmental health analyst, has published and lectured extensively on the effects of chemicals known as endocrine disruptors and their implications for human and wildlife health. Her work has led to major changes in health policy not only in the US but also abroad. She has served as an advisor to the US Environmental Protection Agency, the US State Department’s International Joint Commission, Environment Canada, Health Canada, the US Department of the Interior, the Agency for Toxic Substances and Disease Registry, and similar government agencies in Europe and Japan. She directed World Wildlife Fund’s Wildlife and Contaminants Program before returning to her home in Colorado, in 2002. In 2003 she established TEDX (The Endocrine Disruption Exchange), a non-profit group in Paonia, CO, whose mission is to provide objective, technical information about toxic chemicals to scientists, policy makers, grass-roots and support groups, the media, and the public. In 1985, Dr. Colborn was awarded a Fellowship from the Office of Technology Assessment, US Congress. She held a Chair for three years, starting in 1990, with the W. Alton Jones Foundation, and in 1993 was given a three-year Pew Fellows Award. Among her awards are the 1997 Chatham College Rachel Carson Award, the 1999 Norwegian International Rachel Carson Prize, the 2000 International Blue Planet Prize, the 2003 Society of Toxicology and Environmental Chemistry’s Rachel Carson Award, the 2004 Center for Science in the Public Interest’s Rachel Carson Award, the 2006 Beyond Pesticides Dragonfly Award, the 2007 Lifetime Achievement Award from the National Council for Science and the Environment, TIME magazine’s 2007 Environmental Heroes Award, and the 2008 Swedish Goteborg Award.
