The study published on Monday in the journal JAMA Network Open revealed that eight out of 15 autopsied adults in Germany and Brazil had microplastic inside the brain's olfactory bulb. Researchers from the University of Sao Paulo in Brazil said the tiny plastic particles, now ubiquitous in the air, were likely breathed in by the deceased individuals over their lifetimes.
