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 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.
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 ...
In 1968, organofluorine compounds were detected in the blood serum of consumers, and in 1976, perfluorooctanoic acid (PFOA) or a related compound such as PFOS were suggested as components. [ 6 ] [ 7 ] [ 8 ] In 1997, 3M detected PFOS in blood from global blood banks, [ 9 ] although the company's internal documents indicate knowledge of this ...
There are so many potential health problems that can afflict the feet ? like ingrown toenails, bunions, blisters, and even gout.
[1] [2] C 8 fluorinated urethane constituent [3] that has later been replaced by a C 4 alternative. 3M reformulated Scotchgard and since June 2003 has replaced perfluorooctanesulfonic acid (PFOS) with perfluorobutanesulfonic acid (PFBS). [4] PFBS has a much shorter half-life in people than PFOS (a little over one month vs. 5.4 years).
Symptoms of carbon monoxide poisoning Carbon monoxide makes it difficult for you to breathe. It reduces the ability of blood to carry oxygen to your organs, which means your brain and blood won ...
The most expensive of these scenarios has an initial estimated cost of $1.2 billion, which is roughly $500 million more than the funding provided to affected communities by 3M. [ 9 ] Changes in practices
