    The researchers speculate that microplastics could contribute to neurological conditions by obstructing blood flow, interfering with neural connections, or triggering inflammation in the brain.

    A relative bright spot amidst a sea of bad news:

    "Bottled water alone can expose people to nearly as many microplastic particles annually as all ingested and inhaled sources combined,” said Brandon Luu, an Internal Medicine Resident at the University of Toronto. “Switching to tap water could reduce this exposure by almost 90%, making it one of the simplest ways to cut down on microplastic intake.”

    Dunno if anyone reading this is still drinking bottled water, but, uh, now you have another reason to not do that.

        If you can find a way to do an at home soda making process that doesn’t involve the soda flavor packets being … in plastic… than that would be ideal, I think.

        Similarly, time to go back to beans + grinder or grounds that come in a non plastic package for coffee… stop using keurigs and pods… thats all plastic.

        I just stopped drinking soda regularly and switched over to 99% water a long time ago.

        I treat soda as a dessert, like ice cream or a brownie, only have a few a week, or month.

        Soda and bottled water also have absurdly high margins, absurdly high costs to buy per what it cost the company to make.

        A fountain soda at a fast food place in America has about a 1125% markup / margin.

        If you paid 2 dollars for the soda, the actual soda cost 0.18 cents.

        Not 18 cents.

        0.18 cents.

        A fifth of a penny.

        Bottled water is around 900% to 1000% markup / profit margin.

        As far as I know, off the top if my head, there are not any affordable, attach to the tap in your sink type filters that actually filter out microplastics.

        I may be out of date on that, been about 2 years since I last looked at filters… but yeah, afaik, we have no idea how to effectively filter out microplastics from water at an end user standpoint, as we do for other, older, mkre commonly worried about water pollutants.

        … I guess if you fully boiled all your water to the point it is all steam, and then condenses back ti water, in a glass or metal recepticle, that might do something for reducing microplastics, but that is insanely energy and time intensive.

          That would seem to be the explanation on the face of it. Piping is made from heavier duty plastic. But I’ve heard that PVC can start leaking some nasty chemicals over the decades. Is that better or worse than microplastics?

            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.

        I started putting aluminum foil, folded a few times to the size of a typical card, in my wallet, in each flap… a year or two after credit and debit cards started getting RFID chips (the things that let you tap as oppose to swipe), and thus could be scanned and cloned by a guy walking around with a device in their backpack… and one of my cards was cloned this way.

        Everyone called me paranoid.

        Faraday cages block radio signals… RFID works via radio signals.

        Then, that form of cloning cards became more popular, and now, most wallets just feature a bit of metallic weave or layer in them somewhere to prevent that, or the ekster and ridge wallets that just are metal.

        Yes but to a much lesser extent. The act of merely breaking the seal on the cap injects a lot of plastic into the liquid, so skipping that has to count for something

            You’re right, I misremembered It’s not just about breaking the seal on the cap, the mere friction of the cap on the bottle adds the bulk of microplastics found within

            I was thinking of an article from years ago where they were talking about macro plastics nearly visible to the eye getting into the liquid from breaking the seal. Can’t seem to find it now though

        I was curious about this since a plastic bottle that held water for years doesn’t show any wear on the inside and found out it’s not the bottle that’s the likely source but the filters they use prior to bottling, which have a plastic mesh system. The bottle can stills leech BPA and is best avoided.

        Edit: and we need to keep in mind, the aluminium cans also have a plastic liner inside. So those probably aren’t better either…

        Shit thing, that glass is so heavy to move around.
        And pretty much everything is stored in large plastic containers during production, until it’s filled into whatever.

        Not sure how we can actually get around this.
        The best thing we can do, is probably just reducing the plastic intake, by avoiding plastic bottles, as they are much more prone to decay due to UV light and long term storage.

      I’m a microbiologist but my grad school work, research, and coursework was very chemistry heavy. There are no “probably does somethings” of significance here: the chemistry of plastic generation is extremely well researched.

      Plastic is made of polymerized hydrocarbons, linked up identical tiny units of carbon strands called monomers. Polymerization, the linkage of the monomers into a polymer, requires the use of a catalyst. This is often done with increased heat and pressure to increase the speed of polymerization. Maximum temperatures are around 350°C for certain plastics but are more commonly 140-160°C as higher temperatures can cause the material to break down. Once the desired size of linkage is created, the polymer is capped to keep it from growing further.

      Polymerized hydrocarbons degrade, not further polymerize somehow, at high temperatures like 600° C. Saying there’s some mysterious, high-heat-driven polymerization is like saying burning wood, which is largely a polymer of glucose called cellulose, somehow creates more cellulose as it burns. The burning is due to the release of the energy contained in the bonds in the wood as they break down and react with oxygen.

      Even if the process DID somehow create some plastic, a given mass of brain tissue would be expected to create predictable amounts of this mystery polymer, giving a background measurement that can be subtracted. Again, though, we know how this all works so it’s not really a concern.

        Brain tissue is not as simple as cellulose, but at 600 C with the molecules that make up the molecular soup, there would definitely be some lysing that would take place and form thing like free radicals, these have the potential to react forming longer chains of carbon, which could possibly create a false positive.

    I am longing for plastic-eating bacteria to be released into the wild. There are other materials we can use.

      Think of how many things around you are made of plastic. What about critical pieces of things like airplanes? What would you replace that with to prevent the bacteria from causing damage to them?

      I could probably pick a few things on my desk right now that would be much more difficult and much more costly to produce with other materials.

      The medical field would be categorically fuct. Just the loss of sterile packaging would have serious consequences. Minimally invasive surgeries, joint replacements, bandages that don’t adhere to wounds, stents…

      Then let’s consider cordage. Mountain climbing, arborists, rescue teams, sailboats (the most efficient way to cross oceans), ships, construction… the loss of just Dyneema/UHMWPE, which is a relatively new entrant to the cordage field would have seriously negative impacts.

      There is a lot of energy bound up in those long molecules, and there are no unexploited niches in balanced ecosystems. There are already bacteria that can consume certain polymers under narrow conditions. Humanity is gonna be so screwed for a long time if bacteria can slip those narrow parameters.

      Like what? If you’re building an airplane or a sewer main all substitutes are inferior. The problem is that we’re using the ultra-permanent wonder material for, like, candy wrappers.

      We first need a way to use them to consume plastic in a controlled manner. There are things that simply would not be possible without these polymers and that we do not want destroyed.

      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.

          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

      For real. And now I feel like people are either extremely stupid or just monsters for having kids.

        Despite having no desire to have kids, I’d much rather be born today than pretty much any time before the last few generations.

          That really depends on where you were born and what status you were born into. You could be born into a lot of places today that you would starve or live under miserable conditions.

    Scary. Is plastic more or less expensive than cardboard/paper? I’m not sure if it’s where I live, but I’ve noticed that during my childhood, (example) most takeout containers would be either foil or paper. Now, most of them are plastic, even the cups that contain sauces. I don’t get why plastic has been embraced so much when the alternatives were far easier to recycle.

      Plastic’s a product from the Oil and Gas industry - a crude oil byproduct, naptha into nurdles - and they make a fucktonne of cash from it. Obviously not talking about every type of plastic or the “bio-plastics.” Almost all plastic comes from O&G.

      I recall a moment maybe in the early 2000s when the industry lobby tried arguing they were actually being environmentalists and serving the public good by making plastic out of what would otherwise be toxic waste, like they’re responsibly using every part of the animal. So ridiculous they dropped the campaign within the week iirc.

      But I think about that every time a Premier or Mayor comes out weirdly, strongly opposed to this plastic bag or that plastic straw being banned - that they’re virtue signalling to the O&G lobby.

      So it’s not about what consumers or society embrace, or what’s logical or easier. O&G don’t care if we recycle it, huff the fumes melting it down, or feed it to the fishes. They don’t even really care how little their nurdle sells for, just as long as they can still sell it for something.

      I’m not so sure what cardboard/paper you mean? If you mean something like the paper cups that coffee comes in, they also contain plastic. Dirty paper/cardboard can also not be recycled, so your pizza carton ends up in a landfill or burned. And what do you mean by foil? Genuinely curious.

      In my area a lot of takeout places now offer reusable options for a deposit. Usually it is a cardboard with plastic lining container if it is one way. Except the Asian takeout places, they are all over the place from classic black plastic to aluminum containers to styropor to - circling back - the plastic carton stuff.

      Plastic also has the benefit that it’s really easy to make in whatever shape with injection molding, and is totally permanent, which if you don’t care about disposal is great.

      Meanwhile, making stuff out of a sheet of paper is a manufacturing challenge that has resulted in creative solutions like corrugation, and the container might seep through or soften or something.

      There’s a thing called extended producer responsibility which basically is the idea of making disposal not free anymore for the manufacturer.

        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.

            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

              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.

              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.

                My cast iron pan was made from recycled iron. And if I bought it a month later it would be in the batch that has a product recall because they also recycled some lead in it

                  Yep, that’ll do it. If you have a pile of scrapped iron things, you have to think it wouldn’t be hard to miss something that has a lead battery or weight in it somewhere. Although, I have to wonder why they didn’t test that batch before it was sold, if it’s for cooking in.

                  I seem to remember a story about a radiation source for probing gas wells getting into scrap and causing problems. They just look something like a metal cylinder, so would blend in easily with all the other oil and gas errata getting scrapped.
