Levels of Microplastics in Human Brains May Be Rapidly Rising, Study Suggests
The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study. From a report: It found a rising trend in micro- and nanoplastics in brain tissue from dozens of postmortems carried out between 1997 and 2024...
The exponential rise in microplastic pollution over the past 50 years may be reflected in increasing contamination in human brains, according to a new study. However, the damage dementia causes in the brain would be expected to increase concentrations, the researchers said, meaning no causal link should be assumed. "Given the exponentially rising environmental presence of micro- and nanoplastics, this data compels a much larger effort to understand whether they have a role in neurological disorders or other human health effects," said the researchers, who were led by Prof Matthew Campen at the University of New Mexico in the US.
