Perfluorooctanoic acid (PFOA; conjugate base perfluorooctanoate; also known colloquially as C8, for its 8-carbon chain structure) is a perfluorinated carboxylic acid produced and used worldwide as an industrial surfactant in chemical processes and as a material feedstock.
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 ...
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]
Wyre Council said ICI, and subsequent site owner AGC Chemicals, were permitted to use PFOA from the 1950s to 2012. The substance was used in everyday items like non-stick pans and waterproof clothing.
The state added PFOA to its Proposition 65 list of chemicals that are known to cause reproductive toxicity in 2017 and to the list known to cause cancer in 2022. But it's one of only around a ...
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.
More than 40 textile companies, chemical manufacturers and other industries have for years polluted Columbia’s municipal water supply with “forever chemicals,” a class of man-made compounds ...
January 2007 Dennis Paustenbach, who was the founder of ChemRisk, co-authored an article entitled "A methodology for estimating human exposure to perfluorooctanoic acid (PFOA): a retrospective exposure assessment of a community (1951-2003)" in the Journal of Toxicology and Environmental Health, in which the authors said that " The predicted ...
