Updates: PFOA

Remember the post about Teflon?

Two 2007 studies in Food Additives and Contaminants analyzed the transference of material from non-stick cookware and containers with non-stick surfaces, such as popcorn bags. One of the studies subjected 26 different pieces of non-stick cookware to 30 minutes of 250 degrees Celsius (~450 Fahrenheit)  and found that no significant dose of materials were transferred. The studies were made to simulate regular use under the worse case scenario.

While I am glad to see these results my question still remains unanswered, what happens through the repeated heating and scratching of these surfaces over years? Does it start degrading or not? If any of you has an answer let me know!
