The Race To Destroy PFAS, the Forever Chemicals (technologyreview.com) 36
An anonymous reader shares a report: PFAS stands for "per- and polyfluoroalkyl substances," a family of upwards of 15,000 or more human-made and incredibly durable chemical compounds that have been used in countless industrial and consumer applications for decades. Firefighting foams, waterproof hiking boots, raincoats, nonstick frying pans, dental floss, lipstick, and even the ink used to label packaging -- all can contain PFAS. The compounds are ubiquitous in drinking water and soil, even migrating to Arctic sea ice. PFAS are called forever chemicals because once present in the environment, they do not degrade or break down. They accumulate, are transferred throughout the watershed, and ultimately persist.
The quest to reduce the amount of PFAS in the environment is what led me to an industrial park in a southern suburb of Grand Rapids, Michigan. The jar of PFAS concentrate in my hand is part of a demonstration arranged by my hosts, Revive Environmental, during a tour of the company's PFAS destruction site, one of the first in the country to operate commercially and at scale. A few yards in front of me sits the company's PFAS "Annihilator" in a white shipping container.
The Annihilator represents just one of several technologies now vying to break down and destroy PFAS. These span the gamut from established processes like electrochemical oxidation and supercritical water oxidation to emerging techniques relying on ultraviolet light, plasma, ultrasound, or catalyst-driven thermal processes. Some are deployed in field tests. Other companies are actively running pilot programs, many with various divisions of the US Department of Defense and other government agencies. And many other technologies are still undergoing laboratory research. There's good reason for this. Not only are PFAS everywhere around us; they're also in us. Humans can't break down PFAS, and our bodies struggle to clear them from our systems. Studies suggest they're in my blood and yours -- the majority of Americans,' in fact -- and they have been linked to increased risks of kidney and testicular cancer, decreased infant birthweights, and high blood pressure. And that's only what we know about now: researchers continue to grapple with the full impacts of PFAS on human and environmental health.

Cancer is going to be looked at differently than heart disease because while cancer can be the result of lifestyle choices there are so many more cases where a person can do everything right and still be struck with the disease.
Even if PFAS has been shown to contribute some causative effect on heart disease it would have to be shown to be a stronger effect that what we already know are the main drivers of it (weight, diet, lifestyle).
Breast cancer does have a lot of money behind it for that reason, it strik

Now this is a consequence of imperfect language but colloquially "heart disease" is a moniker for "coronary artery disease (CAD)" which is the most common and often arrhythmia is correlated/caused by CAD.
As for the athletes as far as I am aware there isn't a known causative action for why they suffer from arrhythmia but we do know it is highly correlated to people who engage in high endurance sports, running, cycling, swimming etc, so while it does "just happen" we do know there is a high risk factor based

Also ever notice many of the football player collapsing stories are often more at practice than the actual games, maybe because they are doing drills, laps and calisthenics for hours a time. Go ask a football player if they don't consider it an endurance sport

What are you talking about? Breast cancer causes about 20 deaths/100k people, heart disease causes about 300 deaths/100k people, so all things equal, you'd expect to see ~7% of the funding towards breast cancer that you do heart disease.
In 2022, the US spent about $730M on breast cancer research, and $2750M on cardiovascular research [nih.gov]. So yes, the breast cancer funding rate is comparatively higher than you'd expect based purely on deaths, but hardly "going apeshit" in my opinion. Maybe this is because or adv

Coincidentally, I just watched Dark Waters, a documentary about the environmental lawyer that fought to hold a chemical company accountable for its actions after it made a clusterfuck with PFAS. Surprisingly it was a compelling suspense--it's the same sort of character-driven plot as Oppenheimer.
After reading a bit more [wikipedia.org] on wikipedia and discovering that fluoropolymers on those grease-proof food wrappers are likely to end up inside your body and stay there, I'm considering a personal ban. But that brings up the question of how much I'm willing to sacrifice. Am I willing to walk out of a restaurant if they serve the food in grease-proof takeaway box instead of a plate?
Anyway, it's great that we are cleaning up the environment, but we've got to stop using them for unimportant purposes. It feels like we are still living in the age when mercury and arsenic were used as an anti-inflammatories and antipyretics, but instead of elemental poisons we've switched to polymeric ones.

On the other hand, the technique in this post--supercritical water oxidation, which is what it sounds like but is described well in the article--sounds really cool, because we still do need to break down the PFAS that are leaching out of landfills. The article goes into a lot of other technologies too, but in less detail. Unfortunately it sounds like this is only good for water, since the oxygen will be consumed in reaction with any contaminant. Meaning these techniques can't remove PFAS from sludge (as in

This technique is also only good for point-source pollution, rendering it only useful for localized contamination
PFAS today are no longer point-source pollutants.

To add one more thought (sorry for the self reply), this is a case where polluting the world and its inhabitants is too cheap!
