Summary

Researchers found microplastic particles in the olfactory bulb, the part of the human brain responsible for the sense of smell. This suggests that microplastics may reach the brain through the nasal passage, bypassing the blood-brain barrier. The finding highlights a potential direct route for microplastics to enter the brain, raising concerns about neurotoxicity.

This case series provides evidence of MPs found in the human olfactory bulb, suggesting a potential pathway for the translocation of MPs to the brain. The findings underscore the need for further research on the health implications of MP exposure, particularly concerning neurotoxicity and the potential for MPs to bypass the blood-brain barrier.
