1967 In the wake of the 1967 USS Forrestal fire, which happened off the coast of north Vietnam—"one of the worst disasters in U.S. naval history"—in which 134 people were killed and the U.S. Navy aircraft carrier was almost destroyed, the US Navy began to make it mandatory for its vessels to carry Aqueous Film Forming Foams (AFFF) on board ...
The highest PFOA levels in drinking water were found in the Little Hocking water system, with an average concentration of 3.55 parts per billion during 2002–2005. [15] Individuals who drank more tap water, ate locally grown fruits and vegetables, or ate local meat, were all associated with having higher PFOA levels.
Those surveyed had a range of PFOA levels from 0.2-22,412 μg/L, with a median exposure of 28.2 μg/L. [30] These levels were significantly higher than the levels detected in the general American population, which had a median exposure of 3.9μg/L. [30] Results from the study concluded that PFOA exposure was linked to pancreatic cancer and ...

Regulatory limits for PFOA and PFOS set by the US EPA (4 parts-per-trillion) are limited by the capability of methods to detect low level concentrations. [ 248 ] Non-targeted analyses include total organic fluorine (TOF, including variations, e.g., adsorbable organic fluorine, AOF; extractable organic fluorine, EOF), total oxidizable precursor ...
In contrast, PFOS blood levels appear to be rising in China [28] where PFOS production continues. A study of ca. 2000 teenagers from 9 European countries with most samples collected in years 2016-2018 found higher blood concentrations of several PFOS’s in those, who consumed more seafood, eggs or offal , as well as in those from North and ...
This classic fave makes us feel like a fancy extra in White Lotus. San Pellegrino's sparkling water is solidly in the safe zone when it comes to PFAS levels at .31 ppt ("safe" PFAS levels are seen ...
Fluorotelomer alcohols can biodegrade to perfluorinated carboxylic acids, which persist in the environment and are found in the blood serum of populations and wildlife, such as the toxic PFOA and PFNA. [8] [9] Aerobic biotransformation pathways of 8:2 FTOH in soil [10] The fluorotelomer alcohols 6:2 FTOH and 8:2 FTOH have been found to be ...
