Bioaccumulation of Microplastics in Decedent Human Brains
Increasing Brain Accumulation Over Time, with Fivefold Higher Levels in Dementia Patients
The study titled Bioaccumulation of microplastics in decedent human brains was just published in Nature Medicine:
Abstract
Rising global concentrations of environmental microplastics and nanoplastics (MNPs) drive concerns for human exposure and health outcomes. Complementary methods for the robust detection of tissue MNPs, including pyrolysis gas chromatography–mass spectrometry, attenuated total reflectance–Fourier transform infrared spectroscopy and electron microscopy with energy-dispersive spectroscopy, confirm the presence of MNPs in human kidney, liver and brain. MNPs in these organs primarily consist of polyethylene, with lesser but significant concentrations of other polymers. Brain tissues harbor higher proportions of polyethylene compared to the composition of the plastics in liver or kidney, and electron microscopy verified the nature of the isolated brain MNPs, which present largely as nanoscale shard-like fragments. Plastic concentrations in these decedent tissues were not influenced by age, sex, race/ethnicity or cause of death; the time of death (2016 versus 2024) was a significant factor, with increasing MNP concentrations over time in both liver and brain samples (P = 0.01). Finally, even greater accumulation of MNPs was observed in a cohort of decedent brains with documented dementia diagnosis, with notable deposition in cerebrovascular walls and immune cells. These results highlight a critical need to better understand the routes of exposure, uptake and clearance pathways and potential health consequences of plastics in human tissues, particularly in the brain.

Blood cells are made in the bone marrow. The bone marrow is the soft, spongy material in the center of the bones. It produces about 95% of the body's blood cells. Most of the adult body's bone marrow is in the pelvic bones, breast bone, and the bones of the spine.
So then how is micro plastics getting in your blood stream? Oh I see through digestion.
Nearly all the water is absorbed into the bloodstream from the small intestine. The small intestine is actually the longest segment of the gastrointestinal tract — the long, continuous pathway that food travels through your digestive system. In the small intestine, food is broken down into liquid and most of its nutrients are absorbed. The excess fluid absorbed in the blood is filtered by the kidneys, which produce the urine that is transported to the bladder. The waste is passed on to the large intestine.
The body will only breakdown and metabolize nutrients it can use. Not to say it wont digest any nutrients that can be harmful but those toxins are proteins and other building block minerals, or of the same type as non toxic molecules. Your body rejects things it can't digest and breakdown like polymer carbon chains, plastics, silica, cellulosic fibers. Plaque and fat gets in your blood, because it was once something your body could break down.
It is not going to breakdown plastics.
So if Microplastics were as big of an issue or threat that they say it is. Then it would only stand to reason, that people would be having plastic kidney stones, possibly creating new kinds of bladder and kidney cancers. Colon issues, gut issues, but that is not the case. I remember seeing an online article once about microplastics found in fish, with microscopic images of tiny perfect square particles. But in reality oxidized plastic particles are jagged and irregular. So the images and the study were probably hype and fake. If it were so with the fish, then surely it would be true with humans. This study should have concluded we're getting microplastics in our muscles, but that's impossible. As food does not go down our throats to our muscles directly. No more than consuming glass, wood, paper or corn pericarp.
So why the sudden Heart risk deflection? Are they trying to readily explain away the uncanny coincidental unexplained deaths?
Here they go from listing a litany of ill-health effects, to lamenting that they don't know the health ramification. But they do list a confident inspiring list of organizations, that will make you rest assure that they are on it.

Anytime these assholes use "Holistic Research" what they mean is the science is settled. They need everyone else to research what they are telling them, citing their sources.
Pretty much the sites pushing this nonsense are the usual suspects. WaPo, UN, WHO, NPR they all make up their own AI story and study, nobody ever cites anything. Or explains how micro beads gets absorbed into the bloodstream and gets into fish. How is it that we may be drinking microbeads in liquids or other foods, but the Scientists are only concerned that somehow we will absorb the microplastics through consuming fish meat, that has somehow miraculously converted microplastic particles into its flesh? Why would our body digest that plastic bit but not a sparkly thing from a soda?
Oh and we do get Alex Jones and Co weighing in though.
