There have been several stories lately about the poisons of teflon and the down-right corruption from DuPont (influencing the EPA, among other agencies). There is currently a corporate lawyer battling it out with DuPont in order to get the many people affected by the manufacturing of teflon their settlement, but there’s a long way to go in terms of consumer awareness.
Starting around 1951, DuPont began using another laboratory-formed chemical known as Perfluorooctanoic (PFOA) acid, or C8 (so called because it contains eight carbon molecules), to smooth out the lumpiness of freshly manufactured Teflon. An unusually durable chemical, C8 first entered the world in 1947 and due to its nonstick and stain-resistant properties its use as a “surfactant” spread with extraordinary speed. The white, powdery compound, often said to look like Tide laundry detergent, would ultimately be used in hundreds of products including fast food wrappers, waterproof clothing, electrical cables, and pizza boxes. (DuPont used to purchase C8 from another chemical company called 3M until 2002, when the company phased it out. DuPont then started manufacturing C8 on its own at a factory in Fayetteville, North Carolina.)
The trouble was that the compound – which has since been linked to a variety of health risks including cancer, liver disease, developmental problems, and thyroid disease – escapes into the air easily. In fact, C8 was often shipped to factories pre-mixed with water to keep the dust from worker’s lungs.
Because it’s an extremely stable chemical, C8 does not biodegrade. Instead, it bioaccumulates, building up in people’s blood over time if they continue to drink water or breathe air laced with the substance. Due to its ubiquitous use, the chemical can now be found in trace amounts in the bloodstream of more than 98 percent of Americans, and even in umbilical cord blood and breast milk, according to the Centers for Disease Control. It’s also been found in the blood of seals, eagles, and dolphins around the world, including in animals living in a remote wildlife refuge in the middle of the North Pacific. The chemical is expected to stay in the environment for thousands of years.
