Chinese researchers find microplastics in nearly all human brain samples.
Chinese researchers have found microplastics and nanoplastics in nearly all human brain samples analyzed, including healthy and diseased tissues.
The study suggests these particles may enter the brain when barriers are weakened by disease, linking factors like age and plastic exposure to higher concentrations.
However, the researchers emphasize that while they identified associations, the study does not prove these particles cause brain tumors.
