History

Microplastic particles have been found in the stomachs of five species of small fish caught in coastal waters near Binh Dinh, Vietnam, with each fish containing between 5 and 24 particles on average.

How it works

These fish eat tiny plastic bits floating in the water along with their food, and since the plastic can't be digested or pushed out easily, it just stays inside their stomachs and intestines. That's why scientists find several pieces in each fish — it's not because they're special, but because the...

Most probable mechanism

In Simple Terms

Fish swallow tiny plastic pieces while eating in polluted water, and these plastics get stuck in their stomachs and intestines because they can't be broken down or passed out easily.

Causal chain
1

Microplastic particles in the surrounding water are ingested along with natural food particles during feeding behavior.

2

The physical properties of the microplastics — such as size, shape, and non-digestible composition — prevent their breakdown by digestive enzymes or mechanical processing in the gut.

which leads to
3

The particles accumulate in the digestive tract due to limited expulsion mechanisms, resulting in measurable retention over time.

Fish cured with salt and sea salt from India's east coast have a lot of tiny plastic bits in them—some types of plastic like PVC and polystyrene—and that could be a problem for our health and the environment.

Shellfish collected from sheltered coastal areas in Kenjeran, Indonesia, contain more microplastic particles per kilogram than those from more open coastal areas in Balekambang, likely due to differences in water flow and human pollution sources.
