Microplastics can block blood vessels in mice brains, researchers find

Scientists observe decreased motor function in rodents exposed to microplastics

Microplastics can move through mice brains and block blood vessels, essentially mimicking blood clots that could potentially be fatal or otherwise disrupt brain function.

The findings are detailed in a peer-reviewed paper for which researchers for the first time used real-time imaging to track bits of plastic as they moved through and accumulated in brain blood vessels. When one piece of plastic got stuck, others accumulated behind it, like a car crash", the authors reported.
