Ingesting microplastics-A person may ingest microplastics via drinking water or through eating contaminated seafood. At Tokyo Bay in 2016, scientists examined 64 anchovies for microplastic consumption — 77% had microplastics in their digestive systems.
People have also discovered them within salt, beer, and other food items.
Studies show microplastics may cause oxidative stress, inflammatory reactions, and metabolic disorders in humans. However, further research is needed to confirm these effects.
