Fish caught in Binh Dinh, Vietnam contain tiny plastic particles called microfibers, made from materials like polyethylene and other synthetic polymers, which come from clothing and industrial waste.
Mechanism
Synthesis from 1 study
Fish eat tiny plastic threads floating in the water, and because these plastics don’t dissolve or get digested, they stay inside the fish’s body. The type of plastic found matches what’s used in clothes and factories, so the pollution comes from human-made sources.
Most probable mechanism
Fish swallow tiny plastic threads from the water, and these plastic pieces don’t break down in their bodies, so they get stuck in their guts and tissues over time.
Microfibers from synthetic textiles and industrial waste enter aquatic environments through runoff and wastewater discharge.
Small marine fish ingest these microfibers while feeding on plankton and organic particles in the water column.
The polymers in the microfibers — including polyethylene, polyvinyl ether, polymethacrylate, and polydichloroethylene — resist enzymatic degradation and physical breakdown in the fish digestive tract.
Undigested microfibers accumulate in the gastrointestinal tract and may translocate to internal tissues due to intestinal permeability or phagocytic uptake.
