A community for discussing events around the World
Rule 1: posts have the following requirements:
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.

Has anyone checked how much particles I produce when I wash my fleece jacket.
One thing to note with all these articles; so far, there are no major comprehensive studies that definitively show microplastics are a danger to the body, or show what levels are considered acceptable or not.
Considering the entire world population hasn't just collectively died in the last 50 years, I'm leaning towards the effects of microplastics being negligible, or at least a hell of a lot less dangerous than other established risks like processed meat or direct sunlight.
We tried that approach with leaded gasoline and paint, asbestos building materials, cigarettes, and a variety of other things over the past several generations. They didn't kill the entire world population, but things didn't turn out so well for the people who waited for definitive studies. Good luck with your gamble.

The potential health impacts of microplastics vary based on factors, such as their particle sizes, shape, exposure time, chemical composition (enriched with heavy metals, polycyclic aromatic hydrocarbons (PAHs), etc.), surface properties, and associated contaminants.[76][77]
Experimental and observational studies in mammals have shown that microplastics and nanoplastics exposure have the following adverse effects:
On the cellular level
Inflammation[78][79]
Oxidative stress[80][78][81][82][77]
Genotoxicity[83][82]
Cytotoxicity[81][77]
By systems
Cardiovascular[84][62]
Respiratory[59]
Inflammation in the lungs from inhalation[75]
Disruption of hypothalamic-pituitary axis (HPA), including the Hypothalamic-pituitary-thyroid, Hypothalamic-pituitary-adrenal, Hypothalamic-pituitary-testicular and Hypothalamic-pituitary-ovarian axis[85]
Reproductive toxicity,[85] decreased reproductive health, decreased sperm quality[85]
Developmental abnormalities[85]
Immunotoxicity[85][86][81][79]
Endocrine disruption[85][87]
Neurotoxicity[85]
Metabolic disturbances[78]
Disrupted gut-liver axis resulting in increased risk of insulin resistance[88]
disrupted hormone function, potentially contributing to weight gain.[89][90]
Epidemiological studies
Despite growing concern and evidence, most epidemiologic studies have focused on characterizing exposures. Epidemiological studies directly linking microplastics to adverse health effects in humans remain yet limited and research is ongoing to determine the full extent of potential harm caused by microplastics and their long-term impact on human health.[91][92]
There is plenty of reason to consider microplastics a major adverse health factor. The problem is that it is a relatively new field of research and making an epidemiological assessment is difficult as we are exposed to thousands of harmful substances, so knowing which effect comes from what is not a trivial thing to figure out.
This warning only applies to the pyramid tea bags and not the paper sachet.
It did list cellulose bags as one source, however I don't quite understand how. Additive to strengthen the material?
OMG. That's a good way to start the new year. Now my daily tea is going to be filled with guilt and worry.
You can switch to loose leaf. I thought loose leaf sucked because the tea bits always got in it. Then I found a metal filter that has like, 180nm holes in it. Extremely fine mesh.
I use it more than paper tea bags now!
Get a tea infuser. Loose tea tends to be 100x better quality anyway.
Just buy paper tea bags or loose leaf tea. The article is talking about those stupid nylon “pyramid” tea bags.
This is why I simply tear open the tea bags and dump them into a fine mesh stainless steel basket and set it in the cup.
I have yet to find loose leaf tea tasty enough to repeat buy but I do have 3-4 flavors of bagged tea I always keep stocked.
The biggest downside to doing my favorite bagged teas this way is it’s a pain to clean out the metal basket when I just want another cup the next day, but to me the trade off on sidestepping the microplastic issue is worthwhile
No it's not, because I use a stainless steel capsule and loose leaf tea, which is superior in every way (even if microplastics weren't an issue).
If you don't make your tea like this, do yourself a favor and upgrade to some quality loose leaf!
Edit: lol, I love that this is getting downvotes. Are there disposable teabag enthusiasts out there?
Your tea bag...
No, it's not, because I use something other than tea bags.
That's you. That's what you wrote.
Looks like the risk comes from boiling tea bags made of these materials. Cold steep chads keep winning
You're a monster. I just wanted you to know that.
So... Psychopaths?
These "materials" included cellulose, which is just plant fiber.
Are we really going to start calling plant fibers "bioplastics" now in an effort to scare people?
Polymerized cellulose is by definition a biobased polymer, this isn't anything new. The study doesn't make any claims that polymerized cellulose is harmful. Calling them "plant fibers" is incorrect as they aren't derived directly from a plant, like say, cotton. These are manufactured using cellulose.
Stand down brother, you're up against a cold steep chad
Cold steeping tea is exactly why we can't have nice things.
My arms just grew cold steep bumps!
