Linda FreemanHOST
More than 10,000 people were tested and researchers say that's likely an undercount since the testing only screened for 13 of the thousands of known PFAS compounds out there.
Linda FreemanHOST
One of the most common, PFHXS, is used in furniture, textiles, adhesives, and it turns up in nearly 98% of samples.
Linda FreemanHOST
That isn't a fringe exposure.
Linda FreemanHOST
This is baseline.

Narrowed to veterans ages 20 to 39, the picture changed.

That group showed PFOA levels 13% higher, PFOS 19% higher, and PFHXS 24% higher than civilians the same age, with a combined measure of seven clinically tracked PFAS running 17% higher overall.

Younger veterans were also 18% more likely than similarly-aged civilians to have combined PFAS concentrations at or above 20 nanograms per milliliter, the threshold at which the National Academies of Sciences, Engineering, and Medicine recommends additional clinical monitoring.

Lead author Christian Hoover, a pre-doctoral fellow in Brown's School of Public Health, said the finding comes with a direct recommendation attached—male veterans between 20 and 39 should consider asking a doctor about PFAS testing.

PFOA, PFOSs, the two old workhorses that were the backbone of the Teflon and Scotchgard chemicals, capped at four parts per trillion each.
Darin OlienHOST
And then there's of course many others, PFNA's, PFHxS's, the Gen X, the ones that keep being created.
Darin OlienHOST
But they also capped that at ten parts per trillion and created a hazardous index, which is a s- smart tool that says these chemicals show up together, so we're gonna regulate this mixture of craziness.
Darin OlienHOST
So four parts per trillion.

Deadline: April twenty twenty-nine.
Darin OlienHOST
Then the administration changed.
Darin OlienHOST
May fourteenth, two thousand and twenty-five, new EPA administrator Lee Zeldin announces the agency will keep the PFOA and PFOS limits but push the compliance deadline from twenty twenty-nine to twenty thirty-one and rescinded the limits on the other four, the PFHxS's, the PFNA's, the Gen X, all of these things.
Darin OlienHOST
And the hazard index mixtures completely changed.
