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.
The September 11 attacks and resulting fires caused the release of toxic chemicals used in materials such as stain-resistant coatings. [220] First responders to this incident were exposed to PFOA, PFNA, and PFHxS through inhalation of dust and smoke released during and after the collapse of the World Trade Center. [220]
It was not until the early 1990s that the toxic effects of PFOA became a public concern. Wilbur Tennant, a farmer who lives on his own private land near the DuPont plant in Parkersburg, West Virginia, videotaped the calamitous effects of PFOA on his cattle and local wildlife. Calves were born with black teeth and opaque eyes.
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.
Early 2018 Department of Health & Human Services's Agency for Toxic Substances and Disease Registry (ATSDR) was about to publish its assessment of PFAS chemicals, with a focus on two specific chemicals from the PFAS class—PFOA and PFOS—that have "contaminated water supplies near military bases, chemical plants and other sites from New York ...
The limit for two of the most common types of forever chemicals, known as PFOA and PFOS, is 4 parts per trillion, with a handful of others now limited to 10 parts per trillion.
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, and were replaced by the similarly toxic GenX in Teflon products. PFOA and PFOS are found in every American person’s blood stream in the parts per billion range ...
The plant’s sap is poisonous and is present throughout all parts of the plant. If any part of the plan is ingested it can be fatal, and any contact with eyes can be extremely damaging.
