People in Binh Dinh, Vietnam who eat small fish may ingest a small amount of microplastics each week, estimated to be about one five-hundredth the size of a single rice grain, based on microplastic...
Mechanism
Synthesis from 1 study
When people eat small fish that have swallowed tiny plastic bits, those plastics go through their stomach and intestines without being absorbed or broken down, and come out in poop. The amount is very small — about one five-hundredth the size of a grain of rice — but no one has measured the plastic...
Most probable mechanism
When people eat small fish that have swallowed tiny plastic pieces, those plastics pass through the digestive system without being broken down or absorbed, and are eventually removed from the body in feces.
Microplastic particles present in the tissues of small fish are ingested by humans during consumption of these fish.
The ingested microplastic particles remain intact as they move through the gastrointestinal tract due to their physical resistance to enzymatic and mechanical degradation.
The particles are not absorbed across the intestinal lining into the bloodstream or tissues, and are excreted unchanged in feces.
