Microplastics Are Infiltrating Brain Tissue, Studies Show (theguardian.com) 118
A growing body of scientific evidence shows that microplastics are accumulating in critical human organs, including the brain, leading researchers to call for more urgent actions to rein in plastic pollution. From a report: Studies have detected tiny shards and specks of plastics in human lungs, placentas, reproductive organs, livers, kidneys, knee and elbow joints, blood vessels and bone marrow. Given the research findings, "it is now imperative to declare a global emergency" to deal with plastic pollution, said Sedat Gundogdu, who studies microplastics at Cukurova University in Turkey. Humans are exposed to microplastics -- defined as fragments smaller than 5mm in diameter -- and the chemicals used to make plastics from widespread plastic pollution in air, water and even food.
The health hazards of microplastics within the human body are not yet well-known. Recent studies are just beginning to suggest they could increase the risk of various conditions such as oxidative stress, which can lead to cell damage and inflammation, as well as cardiovascular disease. Animal studies have also linked microplastics to fertility issues, various cancers, a disrupted endocrine and immune system, and impaired learning and memory.

Concern != Emergency (Score:5, Informative)
This may be a new and definitely concerning discovery, but the article itself states, "the health hazards of microplastics within the human body are not yet well-known" then followed by lots of suspicion that they are bad but only suspicion. Given that, perhaps we'd better find out whether they do pose a serious health hazard before we panic and start calling it an emergency? This will also help us to determine how much effort we need to put in to preventing these microplastics.
Also, if you are going to call them "micro" plastics then perhaps the size definition should be tightened up a little since 5 mm is 5,000 "micro" metres, and I hope at least an order or two of magnitude larger than any piece they found in a brain, otherwise rather than pollution as the cause I suspect they were hit in the head by something large and plastic!

I recently got one of those UV flashlights for spotting urine from pets or vermin. I was surprised to find that all of the dusty surfaces in my house glowed brightly.
I guessed that it was because a large proportion of the dust is lint from clothing, and it glows because laundry detergents have UV brighteners. A quick internet search confirmed my theory.
Although we have a lot of 100% cotton clothes, there are plenty of synthetic blends and some 100% synthetic items, so a good proportion of this dust is microplastics. Looking at all the glowing residue highlights just how much plastic everyone is inhaling or ingesting every day.

It hasnt really be that long though. Bakelite and stuff have been around for several generations, but as far as most modern plastics go the boomers were teenagers before they really encountered them in everyday life, and even then they were not in a world completely with plastic waste that breaks down into micro plastics until some time much later.
