Microplastics reached mouse brain tissue in just four weeks.
Mice showed metabolic differences in key organs after exposure.
Human exposure levels to microplastics are comparable to study.

Microplastics Invade Mouse Brains in Weeks

New research indicates that microplastics can travel from the gut to the brain in mice within a mere four weeks. Scientists observed these particles crossing the intestinal barrier and accumulating in various tissues, including brain matter. This rapid migration underscores potential health risks associated with microplastic ingestion.

Further analysis revealed metabolic differences in the colons, livers, and brains of the exposed mice. Given the short duration for these changes to appear, researchers are concerned about the long-term implications for human health, especially considering daily exposure levels are comparable to those used in the study.

While definitive human health impacts are still under investigation, microplastics have been tentatively linked to serious conditions. Scientists are exploring solutions, including plant-based molecules and hydrogels to remove microplastics from water, and encouraging the use of plastic-free alternatives in households.
