New study on Teflon: An environmental group asked the Consumer Product Safety Commission to require that cookware coated with Teflon and similar chemicals carry a label describing potential health risks of the non-stick coating.
The Environmental Working Group said in a study that cookware coated with Teflon-like coatings could reach 700 degrees Fahrenheit in 3-5 minutes, releasing 15 toxic gases and chemicals, including two carcinogens.
In its study, the advocacy group said that internal documents from DuPont (DUP.A), which produces Teflon, show that toxic particles that can kill birds are given off at temperatures as low as 464 degrees. Because of the threat to birds, and possibly humans, each pan should carry a label detailing the potential health risks, the advocacy group said.
Studies investigating the long-term impacts on humans have not been conducted. Still, Teflon and other non-stick chemicals can lead to flu-like systems such as fever or shortness of breath, a condition called polymer fume fever.
