Perfluorooctanoic acid (PFOA) and its salts (perfluorooctanoate, PFO) are fluoropolymer synthesis and processing aids widely used in the field of fluorine chemical industry, and are also fluorinated waterproof/oil/fouling-proof fabrics The main impurities in finishing agents and consumer products. PFOA/PFO is persistent and difficult to degrade, can accumulate in the human body and organisms, and cause interference to the metabolism, reproduction and endocrine systems of the human body and other organisms. The "Special Report on Human Carcinogenic Risks" issued by the International Cancer Institute of the World Health Organization in June 2014 classified PFOA/PFO into category 2B (suspected human carcinogens). PFOA (C8) can be used to produce Teflon, not C8=Teflon, but consumers cannot accurately distinguish whether PFOA is used in the production process of the Teflon used in the purchased pots. When I inquired about the material description of the Supor IH rice cooker I used, I did not see the notice of PFOA exemption. But scientifically speaking, Teflon has a heat resistance of 260 degrees, and it is not safe to use it as an electric rice cooker.
However, it should be noted that the China Environmental News reported in July 2015 "PFOA/PFO Environmental Risk Management and Control Need to Speed Up the Process": At present, China has become the largest PFOA/PFO production, use and discharge country in the world. Environmental prevention and control must be paid more attention. This is very interesting.
