Microplastics Found in Brain Just Hours After Ingestion

A new animal study has found that microplastics can cross the blood-brain barrier and enter the brain just two hours after ingestion via a previously unknown mechanism. The study suggests that microplastics could increase the risk of inflammation, neurological disorders, and neurodegenerative diseases such as Alzheimer's or Parkinson's. Microplastics are found almost everywhere and can enter the human body through drinking water from plastic bottles and food packaging. The researchers hope their new transport model can help improve our understanding of microplastics and their implications on health for future research.
