Scientists issue dire warning: Microplastic accumulation in human brains escalating
-
Regular boiling is pretty good! The micrplastics end up sticking to the calcium deposits left behind. Never been so happy for that stupid white buildup in my kettle!
"As reported in ACS’ Environmental Science & Technology Letters, boiling and filtering calcium-containing tap water could help remove nearly 90% of the nano- and microplastics present."

Fuck, that's good news.
Kinda funny that the tried and true 'works good enough' method of boiling water to cleanse it also works for micro plastics.

You have to remember that plastic containers aren't washed before they are filled with product. That's often where much of the micro/nano plastics come from.
Do you have a source on that? I find it hard to believe we put water into unsanitized bottles.

PVC fell out of use in the 2000s, most buildings use PEX now; but I don't know how that compares.
I believe I've heard that PEX actually breaks down and starts leeching chemicals into the water faster than PVC. It's also a cheaper material. Most of the houses I'm familiar with are still installing PVC.

On the contrary, who didn't?
Let me share with you unique kind of emotions:)
(I mean this in good faith)non-native English speakers. It's actually a distinct source of getting astonished: grow up with some English songs around, love them for their melody and whatnot, then learn some English, then actually listen to or read the lyrics, and... oh, damn. So many things come out in totally different light

It’s been no secret for years now that nanoplastics are lurking in bottled water and in products packaged or wrapped in other kinds of plastic. But new research has called attention to just how big an issue these particles may be.
A study published in January 2024 used new methods to analyze just how many nanoplastic particles really are floating around in the average plastic bottle of water. They found that a liter of bottled water can contain as many as 240,000 tiny plastic fragments. That number is 10 to 100 times more than previous estimates.

permenent? can't plastic get melted down and recycled again?
once i put some plastic container in the dishwasher and it got too hot, it kind of melted a bit. it didn't totally melt but the lid doesn't fit anymore.
i dunno if it was injection molded though
Not very well. Those long molecules break down into shorter segments every time they're recycled, which makes for an inferior and eventually useless product. Some plastics are also thermoset and can't ever be melted again, and some are just hard to recycle for other reasons and get picked out and landfilled. The whole idea of plastics recycling is basically greenwashing on a massive scale; the industry put a lot of money into promoting it to avoid scrutiny.
That being said, they're also permanent in the good way. Plastics don't biodegrade or erode. If you bury a plastic pipe in the ground, it may well still be there and intact in a million years. Anything natural will rot long before that, common metals will corrode, and concrete usually has metal rebar inside that pulls it apart as it corrodes. Plastic is also lightweight, which ceramics (stone-like materials) and metals are not, while still being strong under tension like metals.
Sunlight does slowly break down many plastics, but only into ever-smaller particles, which is where the microplastics in OP come from.

Were the Nazi rumors about them widespread back then?

oh wow, i didn't realize that, i thought it was infinitely reusable just by melting and re-forming it. thank you really much for the explanation.
what you wrote reminded me of silly putty, it's really stretchy and elastic to start with, but if you play with it for a while, it starts to be less elastic and breaks apart.
does metal also break down? i'm thinking about like aluminium cans that are used for soda and stuff like that

Nope, metals are elements as opposed to molecule compounds and literally can be melted and cast forever. They say most of the gold ever mined is still in use today, so your modern ring might have bits of a ring melted down in ancient Egypt in it. Glass is like this too. Paper is more like plastic, albeit somewhat biodegradable when it eventually has to be thrown out.
In practice, there's still a limit for many metals because they will get contaminated. Copper building up in scrap steel is a problem IIRC. It's not a big issue with aluminum, though, unless you're doing something like building an airplane where you need super high purity. Cans are almost all recycled into more cans.
There are ways to purify a metal melt, but they can be expensive and usually produce waste slag. I've never heard of glass being purified; it's probably too cheap to not just make more of, since it's derived from really common minerals.

A lot of metals are fairly easy to recycle. For others, being alloys (basically a mix of various metals in varying quantities), it's more tricky as you can't always really get a pure product out of recycling very easily, so it limits the types of things you can do with them. But all in all it's way better than with plastics.

thank you for the explanation, it was really interesting and in-depth! you should be a teacher!

Thanks! I'm not sure I have the same presence IRL, haha.

Not really. I found it quite ominous never the less

ah don't worry about that, lots of it is online now :3

As opposed to the alternative?
implying there are only two possible options that could ever be imagined is not interesting

The original paper about microplastics in the brain seems to have a serious methodological flaw that undermines the conclusion that our brains are swimming in microplastics.
“False positives of microplastics are common to almost all methods of detecting them,” Jones says. “This is quite a serious issue in microplastics work.”
Brain tissue contains a large amount of lipids, some of which have similar mass spectra as the plastic polyethylene, Wagner says. “Most of the presumed plastic they found is polyethylene, which to me really indicates that they didn’t really clean up their samples properly.” Jones says he shares these concerns.
This is from other microplastics researchers. See this article. So before we panic about this, let’s wait for some independent replication and more agreement in the scientific community.
Microplastics are a serious concern, and we need to deal with plastic pollution. Let’s just stick to high quality science while we do that.
Thank you for the nuance. Bad data and hyperbole doesn't help what I agreed is a serious issue.

So what? We all have to make a bit of sacrifice to maximize shareholder value. Stop whining about it!

I can feel it
plastic pilled micro-maxxer -
I am longing for plastic-eating bacteria to be released into the wild. There are other materials we can use.
There are plastic eating microorganisms, both fungi, and bacteria.
But, they take a long time to break down plastic. I've had a fungus that can digest plastic in a mushroom cultivation bag for nine months and only one specimen has made it through so far.
I imagine splicing the gene that allows for the production of this enzyme into an ocean bound microorganism would clean up a lot of it while not affecting most of our terristrial infrastructure.
Of course, folks put plastic tubing and what not in the ocean too, so I guess we'll all have to die instead.
