It is commonly referred to as the main harmful PFAS chemical and PFOA is responsible for many of the negative health effects commonly associated with PFAS. Per- and polyfluoroalkyl substances are a group of synthetic organofluorine chemical compounds that have multiple fluorine atoms attached to an alkyl chain. Different organizations use ...
1955 A study undertaken by Gordon I. Nordby and J. Murray Luck at Stanford University found that "PFAS binds to proteins in human blood." [21] 1960s DuPont "buried about 200 drums of C8 on the banks of the Ohio River near the plant." [10] 1963 The United States Navy scientists began to work with 3M to develop aqueous film-forming foams (AFFF ...
In 2024, a worldwide study of 45,000 groundwater samples found that 31% of samples contained levels of PFAS that were harmful to human health; these samples were taken from areas not near any obvious source of contamination. [52] Soil is also contaminated and the chemicals have been found in remote areas such as Antarctica. [53]
Let your doctor know you want a lab that measures both linear and branched isomers — and other tips to see the level of PFAS chemicals in your blood.
Within the same country, boys had a higher PFOS concentrations than girls. A typical PFOS blood concentration range in this study was 1,500–2,500 ppb. [29] Much higher levels of blood PFOS (12,830 ppb) have been reported in people with occupational exposure [30] —or possibly 1,656 parts per billion [31] —in a consumer. Occupationally ...
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.

Blood vessels transport blood cells, nutrients, and oxygen to most of the tissues of a body. They also take waste and carbon dioxide away from the tissues. [2] Some tissues such as cartilage, epithelium, and the lens and cornea of the eye are not supplied with blood vessels and are termed avascular.
