As a protonated species, the acid form of PFOA was the most widely used perfluorocarboxylic acid used as a reactive intermediate in the production of fluoroacrylic esters.  The compound is also used in "insulators for electric wires, planar etching of fused silica", fire fighting foam, and outdoor clothing. So while the American Cancer Society confidently states that “non-stick cookware is not a significant source of PFOA exposure,” the manufacturing of Teflon has contributed to the world’s contamination of this forever chemical. All rights reserved. 5”, 11” frying pans, 2QT & 3QT saucepans with lids, 3QT skillet with a lid, and 5QT casserole with lid. Cuisinart is not about just food processors anymore and is a full-service culinary resource with a wide array of products, including kitchen appliances, bakeware, flatware, outdoor grilles, tools, and gadgets. , A proportional hazards regression model was used for each cancer type with the cancer as the outcome and PFOA serum level included as a time-varying covariate.  Municipal wastewater and landfill leachates are considered as important sources of PFOA to the environment,, Most industrialized nations have average PFOA blood serum levels ranging from 2 to 8 parts per billion; the highest consumer sub-population identified was in Korea—with about 60 parts per billion. , In 2010, the three members of the C8 Science Panel published a review of the epidemiological evidence on PFOA exposure in Environmental Health Perspectives.

After media accounts of the effort surfaced, the regional EPA administrator for Colorado denied that EPA had anything to do with suppressing the report. Increased exposure to PFOA and PTFE has been proven to potentially cause flu-like symptoms, kidney damage, liver damage, increased blood pressure, thyroid damage, coronary artery disease, and more (see studies at the end of the post).  Residents were found to have a 6–8 factor increase of PFOA serum levels over unexposed Germans, with average PFOA concentrations in the 22–27 parts per billion range. For example, the estimate for the DuPont Washington Works facility is a total PFOA emissions of 80,000 pounds (lbs) in 2000 and 1,700 pounds in 2004. PFOA serum concentrations were measured at baseline and three to six year follow-up meetings. PFOA can form as a breakdown product from a variety of precursor molecules. When considering its polymer properties, PTFE is a thermoplastic polymer. Children have higher exposures to PFOA through dust compared to adults. PFOA has been manufactured since the 1940s in industrial quantities. Better, but still not technically “non-stick.” I’m trying to save my butter and watch my cholesterol.  As part of the settlement, DuPont has paid for blood tests and health surveys of residents believed to be affected. Your email address will not be published. PTFE is a polymer material containing a large number of repeating units. ", "Wide-scope target analysis of emerging contaminants in landfill leachates and risk assessment using RQ methodology", "Polyfluoroalkyl chemicals in the U.S. population: data from the National Health and Nutrition Examination Survey (NHANES) 2003–2004 and comparisons with NHANES 1999–2000", "Study finds high levels of stain-resistance ingredient in Conasauga River", "Emissions of perfluorinated alkylated substances (PFAS) from point sources—identification of relevant branches", "Substance flow analysis for Switzerland: Perfluorinated surfactants perfluorooctanesulfonate (PFOS) and perfluorooctanoic acid (PFOA)", "Fluorochemical mass flows in a municipal wastewater treatment facility", "Do perfluoropolymers biodegrade into PFOA? Non-stick cookware is not a significant source of PFOA … – Selfmade with ChemDraw (Public Domain) via Commons Wikimedia.  However, a provisional German assessment notes that a 2005 study found PFOA to be genotoxic via a peroxisome proliferation pathway that produced oxygen radicals in HepG2 cells, and a 2006 study demonstrated the induction and suppression of a broad range of genes; therefore, it states that the indirect genotoxic (and thus carcinogenic) potential of PFOA cannot be dismissed. For his work in the exposure of the contamination, lawyer Rob Bilott has received several awards including The Right Livelihood Award in 2017. , An attempt to regulate PFOA in food packaging occurred in the US state of California in 2008.  Along with other related compounds, PFOA exposure was associated with an increased risk of attention deficit hyperactivity disorder (ADHD) in a study of US children aged 12–15.  In a paper presented at the 2009 annual meeting of the International Society of Environmental Epidemiology, PFOA appeared to act as an endocrine disruptor by a potential mechanism on breast maturation in young girls. Since this material is highly unreactive, the chemical species that can make a significant effect on it includes highly reactive chemical species such as alkali metals. The density of this material is about 2200 kg/m3. How general populations are exposed to PFOA is not completely understood. A considerable number of adverse health effects associated with PFOA exposure in humans have been reported.  PFOA has been detected in the central Pacific Ocean at low parts per quadrillion ranges, and at low parts per trillion (ppt) levels in coastal waters.  Two of the most common types (PFOS and PFOA) were phased out of production in the United States (US) in 2002 and 2015 respectively, but are still present in some imported products. There are several applications of PFOA such as carpeting, upholstery, apparel, floor wax, textile, fire-fighting foam and sealants production.  Due to the surfactant nature of PFOA, it has been found to concentrate in the top layers of ocean water. Apart from that, we can use this material as a lubricant as well – PTFE can reduce friction and the energy consumption of machinery. One study that followed a Danish pregnancy cohort suggests that in utero exposure to PFOA could be associated with lower levels of sperm concentration and total sperm count in adult males, reduced testicular size, and higher adjusted levels of luteinizing hormone and follicle-stimulating hormone. , In 2018 the New York State Department of Health adopted drinking water standards of 10 ppt for PFOA and 10 ppt for PFOS, effective in 2019 after a public comment period. , PFOA is released directly from industrial sites. It’s used to make Teflon, and other such water-resistant things, but PFOA is burned off in the process. We have several new patented technologies promising a PFOA-free supply chain. , In 2008 as news stories began to raise concerns about PFOA in microwaved popcorn, Dan Turner, DuPont's global public relations chief, said, "I serve microwave popcorn to my three-year-old."  In the 1980s and 1990s, researchers investigated the toxicity of PFOA.. 3M says they managed their own wastes, but Daikin America "discharged process wastewater to the municipal waste treatment plant".  Overall, PTFE cookware is considered an insignificant exposure pathway to PFOA.  PFOA can be measured in water from industrial sites other than fluorochemical plants. What about new replacement chemicals like GenX? 100% Ceramic cookware and stainless steel sets are probably the best alternatives to Teflon. PTFE is another man-made chemical, most commonly known as Teflon, and has been in commercial use since the 1940s. Although convenient, these highly fluorinated chemicals are associated with some serious health problems. All rights reserved. Another top brand that focuses on ceramic cookware is Cuisinart, founded by the late Carl Sontheimer, who introduced the food processor to America in 1973.  PFOA exposure in the Danish general population was not associated with an increased risk of prostate, bladder, pancreatic, or liver cancer. PFOA (perfluorooctanoic acid) is a synthetic chemical compound that is used, along with PTFE, to manufacture certain fluoropolymer and telomer-based products, including nonstick pan coatings like Teflon.  The water treatment plant received process wastewater from a nearby perfluorochemical manufacturing plant. People can also be exposed to PFOA from ski wax or from fabrics and carpeting that have been treated to be stain resistant.
