HoB, excellent points. a. Just like paint there will be a type of "Solvent Bleed" from many substances. This will decrease over time. You are right that this is below the temperature of decomposition. b.Toxicology of a substance always gets its start from industrial exposure which is usually thousands of times more dangerous than consumer use. The main maxim of toxicology is " Everything is Poisonous, but it depends on the dosage." A worker will be exposed 5 days x 8 hours x X years. We then interpolate what the maximum exposure should be. There are so many chemicals that we are exposed too in the environment and in daily use that it is very hard to pin a health problem on one substance. Is it digested, absorbed through the skin or through the respirtory tract? I have not studied Teflon in detail. So be careful, use in a well ventilated area and use the proper mask. This is a very difficult subject.. The media also sensationalizes many of the problems. They are journalists not scientists. If one person in a million is poisoned by teflon and it incresases to two, that is a 100% increase. That makes the news and it scares the public. The headline reads "100% increase in Teflon poisoning" Then the lawyer vultures step in. Lead, mercury and aluminum are some of the common substances that have well documented side effects. I was brought up during the "lead paint" age and have never shown any side effects. I worked in the aluminum industry which boomed afer WWII. The use of aluminum cookware has been blamed for the increase in arthritis and now alzhiemers. Lead pipes have been blamed for the fall of the Roman empire. Will our ancestors blame teflon for the fall of the US? Who knows.
