Microplastics and Metabolism: Physiological Responses in Mice Following Ingestion

Summary

Researchers found that mice orally exposed to microplastic microspheres showed changes in lipid metabolism and other metabolic pathways, with particles detected in tissues throughout the body. The effects were more pronounced when mice were exposed to mixed microplastic types compared to polystyrene alone, suggesting that real-world mixtures of microplastics may have broader physiological impacts.
