Researchers at the University of New Mexico are studying the growing presence of microplastics in human bodies, including brain tissue. Findings, published in Nature Medicine, show that human brains now contain significant amounts of microplastics – about 7 grams or around five water bottle caps' worth per brain - with higher concentrations in those with dementia. While the health impacts remain unclear, the study highlights the increasing accumulation of microplastics in various organs. These particles, primarily from older plastic waste, raise concerns about potential long-term health risks, including neurodegenerative diseases. Researchers are also investigating how microplastics enter the body, with studies linking them to air, water, and food sources.
