                You can interpret it that way, if you want. However, that wasn’t really what I had in mind. Just pointing out that Americans seem to love acronyms so much that it gets completely ridiculous at times. In highly technical contexts it makes sense when you’re writing documentation or articles for a very small audience.

                For instance, you can shorten Green House Gasses to GHGs if you’re audience consists of climate scientists, but don’t expect the general public to know that acronym. Go ahead and shorten Volatile Organic Compounds to VOCs if you’re writing to chemists. You can talk about CMB when talking to geologists and FFPs when talking to cosmologists, but people outside those fiels probably have never heard of these things let alone the acronyms.

                In normal every day situations it just doesn’t make sense, because you can’t realistically expect everyone to know all of these thousands of accornyms for thousands of more or less common items, situations and things in life.

        Yeah, I’m pessimistic about the huge shift we’d need to make, especially in America. But so much of that packaging is completely unnecessary. Glass jars instead of plastic tubs or bottles. If you visit some places in the UK, they don’t give you single use plastics in hotels and restaurants, though you can still buy that stuff in stores. Water is bottled in glass. Continental breakfast jams are in tiny glass jars. Some snack packages come in waxed paper bags, like what some tortilla chip brands are packaged in here in the US. Paperboard, cardboard, tins and foil. For toiletries, come countries have stores focused on sustainability where you bring your own reusable containers and they have dispensers for things like shampoo and liquid soap. Like a…soda fountain, but for cleaning products.

        People are just so opposed to it here. Like aggressively opposed it it. Like eating yogurt in a glass jar instead of plastic is offensive to them. I don’t get it.

        It’s actually not used everywhere: Cellophane is quite common as its permeable to water vapour but pretty much only that. Bio-sourced (cellulose) and compostable and you’re free to throw it in paper recycling as they’re used to fishing it out of the sludge (it’s what transparent letter windows are made of). And compostable here means in your own backyard, no industrial high-temperature composting needed.

        Many plastics can’t readily be replaced but cellulose and lignin based stuff is at a stage where it can fill many many roles.

        Also don’t forget metal, especially stainless steel. Glass if you want to look inside. All that will need regulation as currently producers are happily externalising costs.

        Now if someone would produce stailness containers that are on the same performance and general engineering level as lock&lock.

            Fun fact, when romans introduced lead pipes through aqueducts across the empire, the lead didn’t affect all populations equally because of this. Hard water regions were mostly spared. Turns out the layer of limescale that forms on pipes is also good at stopping the lead leaching.

        That’s true. I meant we stopped actively using them when building new houses. Though now that I think about it, even that is maybe not true everywhere. But at least it’s something you could change once you identify the problem. Microplastics have permeated everything, they can be found in the depths of the Mariana Trench. There is no getting rid of them (as far as we know).

              All atoms in the biosphere cycle regularly aside from some very longstanding ones.

              If you identify the chemical makeup of the monomer (corroded plastic, micro plastic, whatever you want to call it), there’s nothing stopping you from hypothetically finding or creating enzymes which can digest it. The only reason it hasn’t happened naturally yet is due to a lack of evolutionary pressure to digest the weird compounds we’ve been making up until now.

              Set up farms of modified mycelium or bacteria to scrub the plastics, and stop using many or set up required end of life treatment for plastic manufacturers, and you’ll very rapidly make a dent in plastic spread.

              Further, modify wild biota, such as mushrooms, bacteria, etc to have the ability to produce the same enzymes for assisting in cleanup.

              Big project, yes, but technically feasible. We’ve done more extreme things.

                I’d just point out that these microorganisms will definitely escape into the wild at some point and then durabilty for plastics will be similar (maybe?) to that for wood (there was also a period in time when trees evolved when microorganisms had to catch up to degrade it, presumably it was full of wood everywhere that just wasn’t rotting).

                Imagine a future where your PC screen or mobile phone has an expiry date and it’s not due to planned obsolescence. Maybe that’s not so bad after all, now that I think about it.

                  Meanwhile I’d easily wager 80% or more of plastics have a dwell time once deployed of a few days.

                  In reality, without being in relatively harsh conditions, it’s unlikely for plastics to degrade very quickly even with highly effective digestion.

      Lead is still everywhere. Many electrical cords, Christmas decorations, paint remaining in homes from the 60s and before, even the 70s and possibly 80s. Many tools still sold today, screwdrivers, drill bits, etc. Many fresh produce foods have the potential and often do contain unsafe levels of lead, yes, stuff you buy at the grocery store. Some spices. Stained glass windows. Paints on cheap Chinese or elsewhere toys and other goods. People get lead poisoning today just from living their life not realizing normal stuff around them is dangerous. For real.

      • You know what also has it? Cheap silverware. You can literally rub it off with a terry cloth if you rub the utensil for like a minute straight… a friend of mine showed me one day. It leaves a shimmering powder on the cloth…

        Interesting read, I guess testing on mice is all you can do the behavioral part. But the methods section doesn’t state any weaknesses, I know it’s nor required but you know.

        At the end of the 3-week-long exposure, behavioral testing began. During the open-field test, mice were allowed to explore a low-lit chamber for 90 min with spontaneous movements monitored in the x-, y-, and z-directions. Several parameters to measure behavioral performance were recorded, including distance traveled, rearing activity, and duration in the center. Surprisingly, we found that acute exposure to PS-MPs induced an increase in distance traveled, which was more pronounced in older animals (Figure 3A–D). Similarly, both young and old PS-MP-exposed mice reared significantly more in the open-field, as compared to age-matched controls (Figure 3E–H). Young PS-MP-exposed mice did not spend more time in the center of the chamber overall (Figure 3J), but both low- and high-dose groups spent more time in the center when analyzed as a function of time (Figure 3I). Low- and medium-dose older animals also showed an increased duration in the center (Figure 3K,L).

          I share your concerns regarding the domain name (alleviated by linked study) and methods.

          I’d just like to add that, at least for me, the alarming part is regarding the distribution of these, they seem to be not only lipophillic (which would be expected, considering the nature of them), but also able to cross the blood-brain barrier, something evolved in order to keep bad stuff out (sure, the lipophillic nature explains that part as well, but presumably the fact that they are undissolved but basically very small particles, there was probably some hope towards them not being able to cross).

          To me, this raises some questions regarding what else travels with them, and are they inadvertently becoming a vector for stuff that would normally be more easily disposed of? Thinking of things like the first pass effect here, in the liver where things like ‘naked’ pollutants would be processed/eliminated ‘on sight’; then, if something comes along adsorbed/absorbed into a 3D structure that hides it from the body long enough and then reaches the brain, that something could be potentially leached in a highly unfortunate place. Think targetted drug delivery - only random and with whatever happened to be around while the microplastic was forming.

          Add to this the fact that any and all studies lack a control group since the things are in everything and everyone. Would it even be possible to grow plastic-free lab animals to test them? How would you even isolate the area without using any sort of plastic?

          I predict that behavioral studies are more likely than not to show erratic results due to having different baselines of comparison for each subject because of the heterogeneity of contamination, so even spiking with the same agent in the same manner, you’d be either compounding an effect, potentially countering another or perhaps just eliciting a totally different response. How would one control for that? Maybe get as uniform a starting group as possible but how would you prove that uniformity?

      Don’t heat food in plastic in the microwave. Put in the effort to put it in glass or a plate or so, then heat.

      Don’t store hot leftovers in plastic.

      Don’t buy and drink plastic bottled water.

      If you can in the stores in general chose between food and drinks packaged in glass or cardboard vs anything else: chances are glass or cardboard packaging is the healthier choice. Aluminum cans should still be okayish too, tho they possibly layered it with plastic inside too depending on the pH of the contents to slow down reactions between can and product.

        Let me think. Ah: We could actually solve two problems at once, microplastics and rolling resistance, by using steel wheels on steel streets. Make a street lane two beams of steel, that saves on material, and the wheels conical so that they follow those beams automatically, replacing the car’s differential. In case we need more grip we can spray sand, though as the street is now steel we can also use magnets for breaking. I should patent that!

            Companies love to charge a premium for cotton here (Canada). I try to get Cotton, Linen and Hemp as much as possible, but I end up paying $80 for a t-shirt instead of $30.

      Many, many future generation’s leaded gasoline aswell. You’re welcome, future generations! We thought, we’d add a little something to the mix to take your mind of the climate disaster.

      It’s worse unfortunately. Even if we stopped using plastic materials today the effects from this will carry on for many generations. Fortunately, I’m confident we will also find ways to mitigate the issue over time as well, but it’s a far greater challenge than lead. Perhaps as a positive the symptoms might not be akin to the violent behavior lead caused around the world. We shall see.

    I’m imagining a world where humans live under the spell of microplastics like leaf cutter ants are hypnotized by fungus.

    Oh wait, we already needlessly dig up fossil fuels for the plastic overlords despite all better judgment

    Plastics are into everything. Good luck getting that dirt bag lobby out of Congress.

        Silicone is not actually plastic and definitely don’t break down into microplastics (if they break down at all). There’s varieties leeching suspicious stuff but for some applications the nice ones might actually be the solution of the future, say, for seals for glass jars and stuff. Rubber isn’t better just because it grows on trees, rubber tyres are one of the main sources of microplastics.

        Many of them pay to put macroplastics in their boobs, so not very likely.

    Previous studies have suggested that GFAP expression might decrease in early stages of some neurodegenerative diseases, such as Alzheimer’s disease, or in younger patients with depression disorders.

    So Alzheimer’s or depression, eh? So if I have chronic depression am I safe from Alzheimer’s or am I going to be depressed and constantly forgetting my medication?
