Previous research has suggested widespread PFAS contamination has been a problem for decades; some recent estimates suggest about 96% of Americans currently have some level of PFAS in their blood.
The observed probable serious effects for human health and the environment are thyroid hormonal disturbances and reproductive toxicity seen in rodents, and effects on liver, kidney and haematological system in rats, hormonal disturbances and effects on reproduction in marine medaka fish and effects on expression of hormone receptors in tadpoles.
Milne is one of hundreds of Hyannis residents who participated in a study funded by the Centers for Disease Control and Prevention probing the human health effects of exposure to PFAS, or per- and ...
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.
