The Devil We Know is a 2018 investigative documentary film by director Stephanie Soechtig regarding allegations of health hazards from perfluorooctanoic acid (PFOA, also known as C8), a key ingredient used in manufacturing Teflon, and DuPont's potential responsibility.
Early clinical testing showed a high prevalence of respiratory health effects. Early symptoms of exposure often presented with persistent coughing and wheezing. PFOA and PFHxS levels were present in both smoke and dust exposure, but first responders exposed to smoke had higher concentrations of PFOA and PFHxS than those exposed to dust. [220]
Those surveyed had a range of PFOA levels from 0.2-22,412 μg/L, with a median exposure of 28.2 μg/L. [30] These levels were significantly higher than the levels detected in the general American population, which had a median exposure of 3.9μg/L. [30] Results from the study concluded that PFOA exposure was linked to pancreatic cancer and ...
