PFAS are causing significant harm to the environment, people, pets, and wildlife, but it's not clear that proposed solutions ...

“Given the widespread presence of microplastics in the air, the identification of microplastics in the nose and now in the ...

However, the new study suggests that there's "a potential pathway for the translocation of microplastics to the brain" via ...

A total of 16 different synthetic polymer particles and fibers were identified in olfactory bulbs. The olfactory pathway may ...

Researchers have identified microplastics in the human olfactory bulb, highlighting a potential pathway for these particles ...

Scientists in Brazil found microplastics in the brain tissue of cadavers, according to a new study published Monday in the journal JAMA Network Open. Mounting research over the last few years has ...

The new findings raise concerns among researchers that the olfactory pathway might allow microplastics to access the brain and potentially reach brain areas beyond the olfactory bulb.

Some researchers worry the olfactory pathway may also be an entry point for microplastics getting into the brain, beyond the olfactory bulb. “Previous studies in humans and animals have shown ...

The experts’ identification of microplastics in the nose as well as in the bulb suggests that the olfactory pathway is likely to be an entry site for external particles to the brain. Researchers ...
