Scientists issue dire warning: Microplastic accumulation in human brains escalating
-
I am longing for plastic-eating bacteria to be released into the wild. There are other materials we can use.
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.

The researchers found surprisingly high levels of microplastics in the brain tissue. The concentration of plastics in the brain was much greater than that found in the liver or kidney samples. It was also higher than levels previously reported in placentas and testes. The median amount of total plastics for 2024 brain samples was 4917 micrograms per gram, and for 2016 samples, it was 3345 micrograms per gram. For comparison, the 2024 liver and kidney samples were 433 and 404 micrograms per gram, respectively.
Even more concerning was the finding that the amount of plastic in the brain was increasing over time. Brain tissue samples from 2024 had significantly higher levels of microplastics than samples from 2016, representing an approximate 50% increase in just eight years.
Isn't that the same information just repeated after each other?
To measure the microplastics, the researchers first chemically dissolved the tissue. This created a liquid mixture. They then spun this mixture at very high speeds in a machine called a centrifuge. This process separated out any undissolved materials, including plastics, into a small pellet. Next, they heated this pellet to a very high temperature (600 degrees Celsius), a process that breaks down the plastic.
Why does this sound like somebody explaining this to a 10 year old?

I would like for you to meet my friend, the oyster mushroom. I'm wondering what level of soil accumulation we need to support massive, city-wide oyster mushroom blooms

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.

He believes that food, especially meat, is the primary source of microplastics entering the body, as commercial meat production tends to accumulate plastic particles within the food chain.
“The way we irrigate fields with plastic-contaminated water, we postulate that the plastics build up there,” Campen said. “We feed those crops to our livestock. We take the manure and put it back on the field, so there may be a sort of feed-forward biomagnification.”
Go vegan, I guess?

Yes, and:
“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.”
Is this the case for all plastic bottles? Like for sodas and juices?

The plastic industry is why.

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.
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."

I think that's mostly an issue in America. Here in Europe you can always drink tap water.
We need to immediately research if people in maga areas are the ones who can't drink the tap water

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
Honestly, I'm not saying that you're lying but that's very hard to accept as truth. Would you have a good source for learning about all this?

Plastic sealed brain is better protected?
Brain has plasticity (changes). Just my little joke.

I don't think this is the kind of neuroplasticity we're supposed to be aiming for.

Attach your brain to a 3D printer. Make some use of all that plastic and print your thoughts. /j

Yes, it is. Probably a few phrases written by a human and then a summary of the article with AI.

Plastic is generally cheaper; for a while there was a misguided push against using paper/cardboard because sAvE tHe TrEeS

AI is actually known to not repeat itself. This is also why it tends to use rare/unusual words since it cannot use the same words repeatedly. Not saying this isn't AI, but repetitiveness is not really an AI trait
Known not to repeat itself? You should listen HFY stories.
Just recently listened to one that referred to the gas giant outside several times and the alien chick’s long ears giving away that she’s an alien many times. We get it! Don’t need to introduce her more than once. Jesus.
EDIT: If anyone is interested in the one I was referring to specifically, here you go:

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

Thanks that's very useful and good to know.

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.
