Researchers have issued a concerning warning that a plastic spoon’s worth of microplastics is accumulating inside the human brain. Published in Brain Medicine, the study reveals that the brains of humans contain significant levels of microplastics and nanoplastics (MNPs), with concentrations 3-5 times higher in individuals diagnosed with dementia.
Even more troubling, the study found that the brain’s microplastic levels are 7-30 times higher than those in other organs, such as the liver and kidneys.
