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.
Several strategies have been proposed as a way to protect those who are at greatest risk of occupational exposure to PFAS, including exposure monitoring, regular blood testing, and the use of PFAS-free alternatives such as fluorine-free firefighting foam and plant-based ski wax. [222]
Pearson and her team hired a chemist to test soil and water samples on the properties where 3M had dumped the chemicals. [52] Blood samples from the local population in the affected area were also tested for PFAS. Pearson said that the laboratory tests revealed that there was a "hotspot of contamination in the blood of the community." [52]
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.
The levels of "forever chemicals" known as PFAS in tested North Kent County residents' blood are higher than national averages — and the more unfiltered well water they drank contaminated with ...
Ludtke’s blood test showed a PFAS concentration of 15 nanograms per milliliter. Her children’s results ranged from 6 to 11 nanograms per milliliter. “I was startled when one of my kids ...
PFAS has been found in almost all human blood samples tested, one study found 97% of Americans has PFAS in their blood. [27] PFAS chemicals have been linked to high cholesterol, [28] altered kidney and thyroid function, [29] ulcerative colitis, [30] immunosuppression, [31] decreased effectiveness of vaccines, [32] low birth weight, [33 ...
Toxic chemicals called PFAS are in pesticides sprayed on food and included in pet flea treatments and home bug repellants, a new study found. ... Present in the blood of an estimated 98% of ...
