Summary

Researchers found that chronic exposure to polystyrene microplastics in mice led to learning and memory problems along with signs of neurotoxicity. The study suggests that long-term microplastic exposure may impair brain function in mammals. These findings raise important questions about the potential neurological risks of microplastic exposure for the broader public.

Collectively, our results suggested that PS-MPs exposure can lead to learning and memory dysfunctions and induce neurotoxic effects in mice, findings which have wide-ranging implications for the public regarding the potential risks of MPs. https://doi.org/10.1289/EHP10255.
