To what degree do frying pans have a role in this, if any?
Many frying pans are coated with perfluorinated compounds. You would also see these on many other non-stick coatings like goretex product for example. Exposure from frying pans and jackets will be much lower than people near industrial sources. However, these compounds are extremely persistent and will accumulate in your body throughout your whole lifetime. This is definitely something people should be concerned about.
