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 ...
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.
In humans, PFHxS binds to blood albumin, [8] and relatively little PFHxS is found in the liver compared to longer chain PFASs such as PFOS. [9] The half-life of PFHxS in adult blood serum is 5.3 years (4.7 years for women and 7.4 years for men). [10] The half-life of PFASs in human blood generally decreases with decreasing backbone (CF 2) length.
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]
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 ...
The blood tests checks for per- and polyfluoroalkyl substances — PFAS, a family of over 10,000 long-lasting human-made chemicals used in commercial and industrial products.

Contaminants of emerging concern (CECs) is a term used by water quality professionals to describe pollutants that have been detected in environmental monitoring samples, that may cause ecological or human health impacts, and typically are not regulated under current environmental laws.
