Microplastics and Metabolism: Physiological Responses in Mice Following Ingestion.

The article discusses a study published in the issue which investigated how ingestion of environmentally relevant concentrations and mixtures of microplastics (MPs) affects the functioning of metabolic pathways within the colon, liver, kidney, and brain in rodents. Topics include the use of oral gastric gavage to expose mice to either polystyrene (PS) microspheres or a mixture of manufactured microspheres, observation on PS and mixed microspheres, and finding on metabolomics pathway analyses.
