A study published in 2020 by University of Notre Dame researcher Graham Peaslee and colleagues found that PFAS compounds on the gear’s outer shell eventually degrade into dust particles that can become unstable and shed.

Graham Peaslee, a University of Notre Dame physicist, first determined that firefighters’ equipment contained PFAS in 2018, after he studied 43 pieces of new and used turnout gear.

Graham Peaslee, a PFAS scientist at the University of Notre Dame, also testified against the bill at both hearings.

“Purely misleading testing that no reputable lab would do,” Graham Peaslee, a physicist at the University of Notre Dame, and a widely recognized expert on PFAS, wrote in an email to the newspaper.

It may take as long as 10 years for more definitive studies to be complete, said Graham Peaslee, a physicist at the University of Notre Dame who has spent years studying PFAS compounds, particularly in turf, cosmetics, food packaging and firefighters’ turnout gear.

University of Notre Dame professor Graham Peaslee said we’re discovering new toxic effects of PFAS all the time and these chemicals will far outlive us all.

More innovative methods like particle induced gamma-ray emission (PIGE) spectroscopy, pioneered by Dr. Graham Peaslee at the University of Notre Dame, is a rapid screening method for total fluorine, which is a marker for PFAS but includes non-PFAS too.”

“I got one of the 6,000 emails she sent,” recalled Graham Peaslee, a physics professor at the University of Notre Dame, who studies PFAS.

But many firefighters and experts argue the standard set by that test is unreasonable. Among them is Graham Peaslee, a University of Notre Dame professor, who has used applied nuclear physics to measure and study PFAS in clothing, firefighter gear and various other materials.

Researchers at the University of Notre Dame found PFAS, sometimes called "forever chemicals," in 52% of cosmetics.

Researchers at the University of Notre Dame tested additional samples of the Vet’s turf, and also found the chemicals.

March 09, 2023

Reporters purchased these turf samples from four individual sellers on eBay, and had two pieces tested at the Lancaster, Pa., laboratory of Eurofins Scientific, an international group of 900 labs in 50 countries, and two samples at a lab at the University of Notre Dame.

“Not only did we measure significant concentrations of PFAS in these containers, we can estimate the PFAS that were leaching off creating a direct path of exposure,” said Graham Peaslee, professor of physics in the Department of Physics and Astronomy at Notre Dame and an author of the study.

“Once PFAS gets into [a person’s] blood, they circulate through all the organs,” said Graham Peaslee, a physicist at the University of Notre Dame who has spent years studying PFAS compounds.

“One of the companies was using PFAS on the inner side of the underwear, which is really an odd place to use it,” said Graham Peaslee, professor and PFAS researcher at the University of Notre Dame, adding that it might be a water- or stain-resistant feature of the underwear.

While Thinx advertised its products were free of harmful chemicals, Sierra reporter Jessian Choy was able to prove otherwise back in 2020 with the help of Graham Peaslee, PhD, a physics professor at the University of Notre Dame.

Two nationally renowned scientists are testifying and available for interviews before or after the hearing: Dr. Graham Peaslee, a nuclear chemist and a professor at Notre Dame who has been working on PFAS since 2014 and is now considered one of the world’s top experts.

February 02, 2023

Choy decided to get the products tested herself. She sent samples of two brands to a lab at the University of Notre Dame in Indiana run by Graham Peaslee, PhD, a leading PFAS researcher.

January 17, 2023

Back in 2020, a journalist for Sierra magazine investigated the potential risks of period underwear, sending two brands, including Thinx, to an independent scientist at the University of Notre Dame.

“PFAS are a class of chemicals that are characterized by extremely long environmental persistence,” says Graham Peaslee, professor of physics at the University of Notre Dame who was not involved in the study.

“1.2 million firefighters are wearing this,” Dr. Graham Peaslee, a Notre Dame professor who conducted the study, said.

August 24, 2022

University of Notre Dame researchers, like professor of chemistry and biochemistry Graham Peaslee, have found PFAS chemicals in fast food packaging, firefighter turnout gear and cosmetics.

March 24, 2022

That’s because all PFAS contain organic fluorine, and there are few other sources of the compound, says Graham Peaslee, PhD, a professor of physics, chemistry, and biochemistry at the University of Notre Dame in Indiana, who has studied PFAS in food packaging.

Residents filled "milk jugs, their favorite aquarium tank and two-liter pop bottles" with tap water from their homes, explained Graham Peaslee, professor of chemistry and biochemistry at the University of Notre Dame.

“I'm afraid there are almost no consumer products that are entirely free of PFAS at this point,” Graham Peaslee, PhD, professor of physics at the University of Notre Dame, who is not affiliated with the report, told Verywell.

Graham Peaslee, senior author of the Notre Dame study and professor of physics at the University of Notre Dame, noted in a press release that regular lipstick wearers could ingest a few pounds of lipstick in their lifetime.

“We think that there’s intentional use of this that’s not being declared. We think that the consumer has the right to know what they’re buying,” said Graham Peaslee, Ph.D. a physics professor at the University of Notre Dame.

October 08, 2021

As a study published by researchers at the University of Notre Dame in mid-June found, the problem extends far beyond one palette.

“PFAS is insidious; it’s one of the most persistent chemicals ever made,” says Graham Peaslee, Ph.D., a professor at Notre Dame and one of the world’s leading PFAS researchers.
