A new study identified the tiny pollutants in the olfactory bulbs of eight cadavers, suggesting microplastics can travel through the nose to the brain

Scientists in Brazil found microplastics in the brain tissue of cadavers, according to a new study published Monday in the journal JAMA Network Open.
