Why eating oysters near busy coasts might mean eating more plastic

Scientists checked shellfish from two beaches in Indonesia to see how much tiny plastic bits they had inside, and how much people might eat by having seafood.
No biological mechanisms were identified in this study. This may be an epidemiological, observational, or survey-based study that reports associations rather than proposing causal biological pathways.

There is no reliable scientific method that consistently measures how much plastic people consume each week, so the claim that it equals a credit card's weight is not proven.
People who eat shellfish in Kenjeran ingest more microplastics per day than people who eat shellfish in Balekambang, due to differences in how contaminated the shellfish are and how much people eat.
Microplastics found in shellfish from two locations are mostly smaller than 40 micrometers, a size that bivalves can easily filter from water. These particles are likely fragments of plastic waste that broke down after entering waterways through urban runoff and wastewater.
Oysters contain more microplastics than two other shellfish species studied, because they filter more water and have more tissue, which means people eating them may ingest more microplastics.
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.
