World News
A community for discussing events around the World
Rules:
-
Rule 1: posts have the following requirements:
- Post news articles only
- Video links are NOT articles and will be removed.
- Title must match the article headline
- Not United States Internal News
- Recent (Past 30 Days)
- Screenshots/links to other social media sites (Twitter/X/Facebook/Youtube/reddit, etc.) are explicitly forbidden, as are link shorteners.
-
Rule 2: Do not copy the entire article into your post. The key points in 1-2 paragraphs is allowed (even encouraged!), but large segments of articles posted in the body will result in the post being removed. If you have to stop and think "Is this fair use?", it probably isn't. Archive links, especially the ones created on link submission, are absolutely allowed but those that avoid paywalls are not.
-
Rule 3: Opinions articles, or Articles based on misinformation/propaganda may be removed. Sources that have a Low or Very Low factual reporting rating or MBFC Credibility Rating may be removed.
-
Rule 4: Posts or comments that are homophobic, transphobic, racist, sexist, anti-religious, or ableist will be removed. “Ironic” prejudice is just prejudiced.
-
Posts and comments must abide by the lemmy.world terms of service UPDATED AS OF 10/19
-
Rule 5: Keep it civil. It's OK to say the subject of an article is behaving like a (pejorative, pejorative). It's NOT OK to say another USER is (pejorative). Strong language is fine, just not directed at other members. Engage in good-faith and with respect! This includes accusing another user of being a bot or paid actor. Trolling is uncivil and is grounds for removal and/or a community ban.
Similarly, if you see posts along these lines, do not engage. Report them, block them, and live a happier life than they do. We see too many slapfights that boil down to "Mom! He's bugging me!" and "I'm not touching you!" Going forward, slapfights will result in removed comments and temp bans to cool off.
-
Rule 6: Memes, spam, other low effort posting, reposts, misinformation, advocating violence, off-topic, trolling, offensive, regarding the moderators or meta in content may be removed at any time.
-
Rule 7: We didn't USED to need a rule about how many posts one could make in a day, then someone posted NINETEEN articles in a single day. Not comments, FULL ARTICLES. If you're posting more than say, 10 or so, consider going outside and touching grass. We reserve the right to limit over-posting so a single user does not dominate the front page.
We ask that the users report any comment or post that violate the rules, to use critical thinking when reading, posting or commenting. Users that post off-topic spam, advocate violence, have multiple comments or posts removed, weaponize reports or violate the code of conduct will be banned.
All posts and comments will be reviewed on a case-by-case basis. This means that some content that violates the rules may be allowed, while other content that does not violate the rules may be removed. The moderators retain the right to remove any content and ban users.

Eh... does it?

I still use my non-sticks, but like you said, I'm gonna buy non-PFAS cookware the next time I need to. I'm in no panic about my pans. What people probably should pay more attention to is PFAS in clothing. This might be a tad sensationalist as The Guardian often is, but eh, with a grain of salt: https://www.theguardian.com/fashion/2023/jul/02/fashion-chemicals-pfas-bpa-toxic
Yes, the final product comes back out. The final product is PTFE, not PFAS. PTFE is harmless unless degraded or overheated (which is why you shouldn’t do that with non-stick cookware).
To produce PTFE, PFAS are used (or are intermediaries in the process), which is why the production is dangerous, but the product isn’t.
#Some of the PFAS that have been studied — PFOA, PFOS, and PFHS — can take over seven years to reduce by half in your bloodstream. It's no wonder they're called "forever chemicals."
There’s no PTFE in that list.
So?
We're not talking excretion, we're talking blood half-life.
Too complex a distinction for a corporate shill?
Hey, it’s me, your friendly neighbourhood corporate shill, telling you to not buy any more nonstick cookware because I love Tefal so much. More for me!
But seriously, I’m not disputing that the chemicals you listed are bad, just that the coating itself doesn’t affect you.
PFAS bad, but only there during production. PTFE fine, and that’s what’s on your pan. PTFE does not get into your blood. Any PTFE you consume comes back out, because it is not PFAS.
TL;DR: use pan until pan bad, then buy pan with no PTFE.
Do you understand the difference between excretion and half-life?
Do you understand that anything that has a half-life of SEVERAL YEARS in the blood and is fairly novel and hasn't been studied for long term effects of exposure on humans, should be something which you avoid having in your blood?
It's like when tobacco companies put asbestos in cigarettes to "filter" them.

But yeah, tldr I can agree with
You haven’t shown the half-life of PTFE lol
PFAS is a group of substances, not a substance.
PTFE is Teflon. Weird how someone would shill for DuPont, right?

People like you fucking disgust me. Either you're willfully ignorant or maliciously so. Both are equally pathetic.
Wait up, I just checked and you’re technically right - PTFE is definitely a PFAS. Dunno if it’s dangerous or frequently breaks down into dangerous PFAS, but FWIW I’ve long suspected that nonstick pans can’t be good for you. I’ve never seen a nonstick pan that doesn’t have a single scratch in anyone’s kitchen before.
You could probably stand to improve the clarity of your arguments though haha
Not gonna get very far talking to people like that. Lucky for you I empathize with your intentions,
I hate to step in here, because I fear you're not interested in a discussion, but chemistry is very sensitive to small changes. You can't just notice that two chemicals are related or similar and assume they behave similarly in all situations. It literally takes a degree in chemistry to look at a molecule and start making guesses about its properties.
Then we throw in the fact that we're interested in how these chemicals behave inside your body and it becomes a whole other level of complex. Guessing is practically out the window, as far as I'm concerned, unless you've got some key functional group that stays consistent and exposed whose interactions you already understand. Your body has so many different chemical systems you just plain can't assume similar chemicals will have similar behavior.
Hate to step in here, but you both think PFAS is a substance. It's a group of substances that INCLUDES PTFE.
You'd have better luck of "uhm actuallying" a ~~sixth~~ third grade lesson.
Yeah that's a good point, that's my bad. Polymers isn't my specialty.
