OUR BRAINS ARE SOAKING UP MICROPLASTICS MORE THAN OTHER ORGANS

Summary from the TLDR newsletter

Microplastics have been detected in human brains at much higher concentrations than in other organs. Much of the plastic appears to be smaller than previously thought, with some pieces only about two to three times the size of a virus. People diagnosed with dementia had up to 10 times as much plastic in their brains as others, but there is not enough evidence to definitively conclude on cause or effect. It is unknown what effect microplastics have on human health, but the tiniest pieces can cross the blood-brain barrier.
