As detailed in a yet-to-be-peer-reviewed paper, scientists found that all 91 brain samples they examined, taken from autopsied bodies earlier this year, contained microplastics.
The samples contained ten to 20 times more microplastics than liver and kidney samples collected from the same bodies, suggesting human grey matter is a major dumping ground for the tiny particulates.
The human brain can now be added to an already lengthy list of body parts that have been found to be riddled with plastics, raising significant health concerns.
Previous studies have linked the presence of microplastics with fertility issues, disrupted immune systems, impaired memory, and even a wave of cancer in young people.
