Levels of Microplastics in Human Brains May Be Rapidly Rising, Study Suggests (theguardian.com) 29
The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study. From a report: It found a rising trend in micro- and nanoplastics in brain tissue from dozens of postmortems carried out between 1997 and 2024. The researchers also found the tiny particles in liver and kidney samples. The human body is widely contaminated by microplastics. They have also been found in blood, semen, breast milk, placentas and bone marrow. The impact on human health is largely unknown, but they have been linked to strokes and heart attacks.
The scientists also found that the concentration of microplastics was about six times higher in brain samples from people who had dementia. However, the damage dementia causes in the brain would be expected to increase concentrations, the researchers said, meaning no causal link should be assumed. "Given the exponentially rising environmental presence of micro- and nanoplastics, this data compels a much larger effort to understand whether they have a role in neurological disorders or other human health effects," said the researchers, who were led by Prof Matthew Campen at the University of New Mexico in the US.

The plastic doesn't disappear and it's still mass produced, we will be seeing higher levels.

Every time you use a plastic scrubbie on your pots and pans, you are creating microplastics.
Everytime you wash and dry clothes made from synthetic materials, you are creating microplastics.
Any time you break a piece of plastic, you are creating microplastics.
All of the above, and more, gets into our water sources which leads to the foods we eat, not to mention that which gets into the air we breathe.
As the other poster said, literally everything.

I believe most microplastics are released by people sanding boats and cars. Have you ever sanded Bondo/filler/fairing compound? It's polyester. Catalyzed polyester just like your poly pajamas, but it's used for shaping and fairing before painting. Most builders sand off about 3/4ths of what they mix up and apply.
For boat yards, which are near waterways, this is often done in the open air. Car shops generally (are supposed to use) filters to pick up sanding residue, but most of them just do it outside and le
Where it comes from (Score:1)
A lot of plastic waste ends up in waterways and the ocean, where the environment gradually breaks it down into smaller and smaller particles that wash around the world and into anything and everything we get from the ground. Some were even found on top of Everest, suggesting the particles are in wind and/or rain.

It's not that microplastics are the blame there, it's that stupid people reproduce at a much higher rate than intelligent people.

Is the differentiator intelligence, or education? And is there a verified statistic you can point to or is this mere supposition?
It does satisfy the wishes of some of the statement was shown to be true, but wishing does not make it so.

Strokes, heart attacks, and dementia sound like things correlated to age and poor health. People that are older would have had more time alive to accumulate micro-plastics in their body. People in poor health might be eating more food, lower quality food, have plastic hoses feeding them fluids by IV, air into their lungs, or whatever, or some combination of the above.

Microplastics are different. Elon Musk, Donald Trump and Xi Jinping probably have just as many microplastics in their brains as the guy who works the counter at the local gas station, and they can't escape it. This problem just might get addressed.
