Tiny plastic particles are being found everywhere, including in the human brain. But it is not yet clear which findings can be trusted and what they might mean.
The issue of whether plastics are entering human tissues and what impacts they might have on health is understandably of great interest to scientists, industry and society.
Indeed, for the past few years there have been news stories almost every month about peer-reviewed articles that have reported findings of plastic particles in all sorts of human tissues and bodily fluids — including the lungs, heart, penis, placenta and breast milk.
And in multiple countries, policymakers are being urged to implement measures to limit people’s exposure to nanoplastics and microplastics.
I mean regardless of the research and how bad this turns out to be. At a minimum, I don’t think its freaking great.
Oil based molecules that interrupt and modulate hormones can in no way simply be “neutral” for your health. Of course they are bad, how bad is the only real question.
I’m going to say that it is bad for your health, but microplastic lobbyists have paid our politicians to “question the science” so we can’t confirm that it’s bad for our health until it’s too late.
Instead politicians will encourage us to invent a pill that removes microplastics from the body so they can claim that capitalism works thanks to American innovation.
I’ve seen some people on Reddit believe that microplastics are as bad as lead and asbestos was when everyone was exposed to that in previous generations. We know for sure it’s far less toxic than those. More research is needed to determine if it’s toxic at all.
Is smoking cigarettes really bad for you?
*Spends decades doing “more rigorous science” *
Wow, turns out smoking is bad for you! Who knew.
Reminds me of similar industry sourced propaganda from big oil re climate change, cigarettes re cancer, tech companies re smartphones next to your brain and testicles, etc. They’re all bad, but they gotta keep us hooked with doubt.
Did microplastics wrote this article?
I mean, we do require more research but it’s kinda obvious that there is something there.

> The current evidence base (largely based upon animal and cell culture studies) suggests that MNP exposure can lead to adverse health impacts via oxidative stress, inflammation, immune dysfunction, altered biochemical/energy metabolism, impaired cell proliferation, abnormal organ development, disrupted metabolic pathways, and carcinogenicity. These can lead to direct or indirect consequences to various organ systems, including respiratory, gastrointestinal, cardiovascular, hepatic, renal, nervous, reproductive, immune, endocrine, and muscular. Particularly, a recent study in The New England Journal of Medicine found that people with a carotid artery plaque in which MNPs were detected had a higher risk of myocardial infarction, stroke, or all-cause mortality. Additionally, inflammatory bowel disease (IBD) patients’ stool contained about 1.5 times more microplastics than healthy controls, averaging 41.8 vs. 28.0 particles per gram of dry stool. However, the underlying mechanisms and whether long-term exposure to MNPs is associated with disease susceptibility is an area that requires further investigation.
> Due to the higher concentration in the brain, the 3–5 times higher amount in brains with dementia, specific attention should be given to the nanoparticles <200 nm, predominantly polyethylene, found in the brain. […] Is dementia weakening the blood-brain barrier, allowing more microplastics to enter? Or do microplastics, once inside, trigger microinflammation and make it harder for the brain to clear proteins, potentially worsening neurodegeneration?
Science has got a big problem here, you won’t find anyone without micro plastics in their bodies for a control group.
“is lead paint bad for your health? Maybe just a little isn’t so bad.” But yeah, more science is needed… ffs.
It’s more how bad are they? You can’t throw a bunch of oil based crap into your body and expect nothing bad to come of it.
