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.
2016 The EPA "published a voluntary health advisory for PFOA and PFOS" which warned that "exposure to the chemicals at levels above 70 parts per trillion, total, could be dangerous." [71] 2016 The city of Lake Elmo, Minnesota, sued 3M a second time for polluting their drinking water with PFAS chemicals.
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]
That specific chemical compound is called perfluorooctanoic acid, or PFOA. Here's what you need to know. Sure, we've all said, "Eh, everything causes cancer," but the risks of PFOA are not over ...
The EPA estimates thousands of PFAS are already in the U.S. environment and can be found in drinking water, soil, food, household items such as carpets and cookware, and more.
The general population has been exposed to PFOA through massive dumping of C8 waste into the ocean and near the Ohio River Valley. [82] [83] [84] PFOA has been detected in industrial waste, stain-resistant carpets, carpet cleaning liquids, house dust, microwave popcorn bags, water, food and PTFE cookware.
A December 2024 study in the journal Chemosphere incorrectly calculated the amount of potentially toxic flame retardants that could be present in some black plastic household products such as ...
An "incident" of chemical food contamination may be defined as an episodic occurrence of adverse health effects in humans (or animals that might be consumed by humans) following high exposure to particular chemicals, or instances where episodically high concentrations of chemical hazards were detected in the food chain and traced back to a particular event.
