Plastic in our brains: Study shows a 50% increase in just 8 years

There’s more plastic in our brains than in our liver or kidneys.

Plastic is everywhere, including in our brains. According to a preprint in the National Library of Medicine, samples from human brains collected in 2024 contain 50% more plastic than samples collected in 2016. On average, the researchers found that today 0.48% of the human brain is made up of micro and nano plastic particles.
