Microplastic could enter human brain just from breathing: Study
A study published in JAMA Network Open has found microplastics in olfactory bulb, the brain's smell centre, for the first time. Researchers discovered microplastics in 8 of 15 autopsied adults from Germany and Brazil. These particles, prevalent in the air, were likely breathed in by the deceased individuals over their lifetimes, suggesting a potential link to neurological disorders like dementia.
