How to pronounce“pfa”in English

But PFAS have also been linked to dozens of other conditions, and above 20 parts per billion, the risk is even greater.

Videos like PFAS or Monsanto might make big companies mad at us.

And now back to PFAS.

is likely PFAS-containing products.

- And get the PFAS juices going.

But Rachel Pfaff comes to particle physics from a totally different angle.

This map shows PFAS contamination across the US.

Which is why you might also know PFAS under a different name, forever chemicals.

- I've been doing blood testing on PFAS since 2007, and I've never seen a non-detect.

- Perhaps the most comprehensive document on PFAS toxicity was published in 2022 by the National Academies of Sciences, Engineering, and Medicine.

Although the exact mechanism by which PFAS cause harm isn't fully understood, exposure has most consistently been associated

- The combined sum of all the PFAS detected in my blood was 17.92 parts per billion, more than double the US median.

The same goes for most other PFAS-containing products.

So the bigger problem is how easily PFAS from these products can end up in the environment.

A lot of it comes packaged in PFAS-treated materials, like takeout boxes, microwave popcorn bags, and burger wrappers.

pasas P what what does that pfas so per and polyfloral alkalol substances it's a

Chemical companies like DuPont have been making PFAS since the 1930s.

If you look at the kinds of PFAS in that sample, you'll notice something else in the water.

But a larger effort to eliminate PFAS chemicals is still pending.

The generic term for all of these substances is PFAS, per- and polyfluoroalkyl substances, and like Teflon, they have almost magical qualities.

They repel liquids, so PFAS are used to make clothing waterproof.

The trouble is that the same carbon-fluorine bonds that make PFAS so stable and useful in consumer products also make them incredibly persistent in the environment.

- Has anyone ever come back with blood that has zero PFAS whatsoever?

- I wanna make a distinction because it turns out not all PFAS are equally dangerous.

- Yeah, really get that PFAS in that water, right.

And you can see similar results in some of the other PFAS species.

with two parts per billion of PFOA in it because PFAS accumulate in your body over time.

This is especially true if you live near a PFAS factory where the local water is often heavily contaminated.

Additionally, toxins such as PFAS can be found in certain compostable materials.

Forever chemicals, or “PFAS”, have strong molecular bonds that repel oil, water, and stains and can withstand extreme heat, making them almost indestructible.

But by then, PFAS contamination had cropped up elsewhere.

This spot in the Haw is directly impacted by the PFAS load that's coming directly from

Filters at the treatment facility are not designed to remove PFAS.

When DuPont agreed to stop making the Teflon PFAS “C8” by 2015, C8 blood levels dropped for the average American.

There is still no legal requirement to filter PFAS from tap water, so more than 100 million Americans are likely drinking water contaminated with PFAS.

huge chemical class of about 15,000 different chemicals and that includes things like PFA pfos and PTFE which are more

I'm just below the level where the National Academies recommend additional screenings for PFAS-related diseases.

- We actually did tests at the lab with stuff that usually contains PFAS.

A 2019 study found that eating fast food and microwave popcorn especially can increase your PFAS load while eating homecooked meals doesn't.

So these barriers, known as the PFAS chemicals, they're also hormonally active and have many impacts

So wastewater coming from nearby industries arrives and leaves containing similar levels of PFAS contamination.

I worked with Gregor to make the exposes on Teflon, and PFAS, and Monsanto, with Casper to make entropy, the principle of lease action series,

And I also want to shout out people in the comments of our previous video on PFAS suggesting that we should cover Monsanto.

Even the screen you're watching this on, likely has a PFAS anti-smudge coating.

Every continent, including Antarctica, has PFAS all over it.

- So I hear that 98% of the population has PFAS in their blood, but I'm looking for that 2% that doesn't

Now, there are more than just two groups of PFAS and even different definitions of what PFAS even are, but most of what we know really relates

Because usually you interact with these products when they're hot and then see if any of the PFAS leaches off and you potentially eat them or drink them.

But even something as simple as reheating your food on a plate instead of in the original packaging could prevent PFAS from migrating to your food.
