3M May Escape Toxic Chemical, PFAS Manufacturing Legacy (bloomberg.com)
starwatch 5 hours ago [-]
If you want more context on PFAS, I recommend this Veritasium video [0]. It expanded on my usual thought of "PFAS = bad," explaining why non-stick cookware is probably fine while other forms of PFAS are problematic. The video also covers the environmental damage caused by PFAS manufacturing.

skiers have been putting teflon wax on their skis for decades now

it's in the snow, ground, and water-supply

forever

horsawlarway 1 hours ago [-]
It's not like this is going unnoticed either, though.

The International Ski Federation (FIS) now bans fluorinated wax in all their competitions, and this wax is explicitly called out alongside cookware in much of the legislation that's going around in places like CA/CO for PFAS bans.

According to the linked Veritasium video, Teflon is not directly problematic, it’s the chemicals used to manufacture Teflon that are the problem.

Veritasium seems to be frequently wrong or at least incomplete. I empathise, it’s hard to make definitive statements like that, but maybe at some point it’s better not to if you’re not sure and more about entertainment than anything else.

"Teflon" ski wax (fluoro-wax) contains PFOA impurities, which is that same problematic chemical. It's expensive to remove so most manufacturers don't bother.

That article's only citation is a review paper, and it doesn't answer my question or substantiate your claim. It only covers how much PFAS is found in rainwater, and not how it got there.

The sources cited includes https://doi.org/10.1016/j.watres.2020.116685, which is paywalled, but the snippet of the conclusion that is shown indicates that a possible major cause is industrial emissions:

> As local sources were determined to be significant, the results imply that local action can have an impact on PFAS contamination in precipitation. A three-way ANOVA model determined that functional group, chain length, and location were significant predictors of PFAS concentrations

If you can get the full text I'd be very interested in reading about it.

> n Figure 1B, the levels of PFOS in rainwater are shown to often exceed the US EPA drinking water health advisory for PFOS, except for two studies conducted in remote regions (in Tibet and Antarctica).

I don't think there are a lot of industrial emissions in Antarctica.

But still a lot of things do, pesticides following the rain cycles is a good example. We're killing the biodiversity and ourselves with it. We already almost entirely rely on synthetically amending fields with petrol byproducts to feed ourselves, tomorrow we might have to manually pollinate crops when insects won't be enough to do the job.

PFAS are a problem, co2 is a problem, but we have dozens of other very big problems that are partially, if not entirely, obscured

That the way the parent comment is written evokes fear unnecessarily.

There are no definite provable effects of exposure of PFAS - in fact our current knowledge of them is so bad that if you use google and find a list of effects on the body from exposure of PFAS the list is endless and full of things that are unrelated, which is obviously impossible and nonsense.

I've been struggling to understand why people care more about Gaza, Ukraine, BLM, or trans bathrooms than issues like PFAS proliferation and ultimately came to the conclusion that people really just don't care about hypothetical future generations as much as the present. You can point and say "look, this action doesn't affect you much and just makes a 0.01% difference, but it will effect 100,000 future generations of life on this planet and can never be reversed" and people will still say "wow that's sad, but there are people starving in Country A" and be much more concerned.

I guess it's us that are the weird ones.

People care about things that there are campaigns about, that get media coverage. They also avoid thinking about things that they think cannot be changed. These are correlated: if there is a campaign to change something people think it cannot be changed.

Let's compare to Purdue and the Sacklers, shall we?

Purdue owns a huge piece of the responsibility for the opioid epidemic. They created OxyContin and lied about it's addictiveness. They are probably responsible for the deaths of hundreds of thousands of people at this point. The Sacklers were heavily involved in all aspects of this and became billionaires because of it.

Nobody has been criminally charged. The government tried to give them a Jeffrey Epstein level pass by essentially allowing them to pay a few billion dollars over 20 years, which essentially amounted to interest off their ill-gotten gains. Last I heard an appeals court said no, you can't do that and release liability. This really was a slap on the wrist.

Now compare this to what China does [1][2][3].

Remember how all those people went to jail for mortgage fraud after 2008? Oh wait... And now? We just sell pardons [4]. This sort of thing used to cause a scandal (eg [5]).

>Nobody has been criminally charged. The government tried to give them a Jeffrey Epstein level pass by essentially allowing them to pay a few billion dollars over 20 years

Doesn't that settlement only cover civil claims? It doesn't grant them immunity over any criminal claims. It's more correct to say that they didn't bother prosecuting them criminally (possibly because it's hard to do so), and got a civil settlement instead because the evidentiary standards are lower.

> which essentially amounted to interest off their ill-gotten gains.

They offered to pay $6B of $11B gains. Maybe you think they should have been fined $100 trillion or whatever for all the harm they caused, but that money doesn't exist, and moreover it's unclear whether a long drawn out legal battle would result in more money than the settlement they offered.

Paying $6B out of $11B earned from literally killing hundreds of thousands of people.

Meanwhile Alex Jones receives a $1.5B judgement (against ~$10 mil in assets) for just harassing people that were killed?

Even involuntary manslaughter comes with years of jail time. Recklessly killing a single human being. Willfully destroying thousands? Nah, just give us some of the money you earned and we're square.

How does this make sense? This is an extreme injustice no matter how you look at it. The Sacklers deserve far, far worse.

gruez 2 hours ago [-]
>Meanwhile Alex Jones receives a $1.5B judgement (against ~$10 mil in assets)

You answered your own question. $10M doesn't buy a lot of lawyering. $11B Does. Moreover Alex Jones was dumb and did his misdeeds in a way that makes it a slam dunk to sue him in court. The linked article above mentions why suing the Sacklers is much tougher:

>How are you going to get the Sacklers to give up all their money? You could sue them, sure, of course. The entity that is most obvious liable for the opioid crisis is Purdue, the company, which is very bankrupt, but you can probably find some causes of action to sue the Sacklers. For one thing, some Sacklers were executives or board members of Purdue, so you could sue them personally for their own actions running Purdue. (But not all of them were.) For another thing, there are arguments under the bankruptcy code that they should not have been able to extract $11 billion from the company while it was facing all this opioid liability, that the dividends they got were “fraudulent transfers” and can be clawed back by the company.

>There are problems with all of this. There are a lot of Sacklers. They can hire good lawyers. Some of them live abroad. Much of their money is in trusts that a US court might not be able to get access to. If you sued all of them, it would be expensive and time-consuming and you might not get much money. You might! And you might at least make life very unpleasant for them, which has its own virtues.

Finally, the supreme court votes show how divided the justices were. Contrary to the popular expectation that Republicans are pro-business, they were actually the ones voting against the settlement. The justices voting against the settlement were Trump, HW Bush, W Bush, Trump, and Biden appointees; justices voting for the settlement were Trump, W Bush, Obama, and Obama appointees.

3M knowingly poisoned every single person in the world for decades.

Let them burn, and salt the earth where they fall. These fuckers don’t deserve a second chance.

How could they have done it better? Acknowledge the science when the problem was discovered in the 70s, publish the findings, let the scientific community study the problem and let people make informed decisions about the dangers. Had they done that PFAs might still be in use in very controlled circumstances. They certainly wouldn’t be used as waterproofing on our paper plates.

doug_durham 3 hours ago [-]
Poisoned? You need to do more research. The regulations put in place since the early 2000's have already reduced exposure by 70 to 80%. The levels are subclinical. The chemicals persist in the environment indefinitely because they are chemically inert. The interactions with biological systems are more mechanical than chemical. It's not a great situation to be in, but it is unlikely to cause large amounts of long term harm.

A recent article in The Atlantic said that one scientist would know it's harmful to humans and another would know it's in all human blood and 3M made sure they'd never meet.

So the scientist who knew it was harmful didn't know it was everywhere and the scientist who knew it was everywhere didn't know it was harmful.

Point is that it's possible to silo scientists in this way so they can't see the big picture.

A small business, which practically is comprised of - in the US in most cases 1 employee, or maybe 1-3 employees, most likely related.

That person, who you say did a copyright issues, but maybe I say, accidentally used a chopsaw on someones hand... they're liable.

Counter-hypothesis: This is a systemic issue. Decisionmakers and shareholders that cause harm face very little consequences if their behavior does not violate the letter of the law.

> What have you done in your own home? I’d be curious to know.

I've gotten rid of anything in my kitchen that I can that contains PFAS or is produced with PFAS or PFOAs. I use cast iron or stainless steel cookware, glass and silicone only for things that cannot be made of stainless steel. I've more or less eliminated plastics as much as possible from the kitchen. Unfortunately, I can't necessarily do that with food packaging, but even there when I have an option I will change brands or stores to buy things without plastic packaging, or paper packaging coated in PFAS/Teflon. Similarly to avoid PFAS and other chemicals in the production of plastics, as well as microplastics, I almost exclusively buy clothing made entirely from natural fibers.

Beyond that, I have a whole home water filtration system, and after that whole home filtration system I additionally run an undersink 5-stage RO system, both of which are NSF/ANSI certified (53 for the filter system and 58 for the RO system) to remove PFAS and PFOAs. I also go out of my way to find and buy products that don't contain added PFAS, because unfortunately PFAS are in many basic everyday household products like dishwasher detergent, rinse aid, laundry detergent, fabric softener, and the like. If you dig into this you will be disturbed at how many things have PFAS intentionally added to them, and then you will be even more disturbed to find out how many things contain PFAS incidentally, mostly due to contaminated water supplies.

Even with all of this effort, and more I'm not detailing in this comment, I am exposed to PFAS in the food supply and water supply daily, and in a myriad of other ways. It's impossible to avoid, even with a major budget and being extremely conscious of this issue. There is no way to get away from it. The entire world is contaminated. I don't even know how much my mitigations have any helpful effect towards my health, because it's so difficult to mitigate.
