Thanks, Egon. Excellent reference. That is the first half of the required information. The chemicals do migrate in extremely small quantities into people. Before there should be widespread excitement we need to get an additional scientifically derived result. This additional result is that there is a measured toxic effect of some sort attributed to the substance at the levels of contamination measured.
There are myriad man made substances turning up in humans. Some pose a clear and present risk and some don't. If the Teflon related substances are shown to cause human health problems, in the concentrations normally observed, I will abandon Teflon cookware, at least in high temp applications as I don't think Teflon at below or not much above body temperature will migrate into a persons body anywhere near like eating hot microwaved popcorn. OR doing high temp cooking with a Teflon skillet.
As a person with lots of electronics hands on experience with Teflon coated wiries I think the lead exposure through soldering was probably much more dangerous than the Teflon exposure.
I have a perfectly good set of stainless steel pots and pans with thick aluminum pads on the bottoms for even heat spreading so it isn't like I can't dodge Teflon in high temp cooking. My highest temp cooking is in a wok and of course it is not Teflon coated.
We'll have to monitor the "informed sources" and see what if any prelim results are found in toxicity studies that would quantify the risk.
