In Semarang, some adolescents who eat a lot of seafood may ingest up to 427 microplastic particles per day, but these high numbers are based on estimates that go beyond what has been directly...
Mechanism
Synthesis from 1 study
Some teens eat way more shellfish than others, and since shellfish can have tiny plastic bits inside, those teens end up swallowing more plastic. The highest numbers we see are probably inflated because they’re calculated using math, not direct counts of plastic in their bodies.
Most probable mechanism
Some teenagers eat a lot more shellfish than others, and since shellfish can contain tiny plastic pieces, those who eat more get more plastic in their bodies. The highest amounts seen are from people who eat unusually large portions, but these numbers might be higher than what actually happens because they’re estimated using math models, not direct measurements.
Individuals consume varying quantities of seafood, particularly filter-feeding shellfish, which accumulate microplastics from surrounding marine environments.
Microplastics ingested with seafood pass through the gastrointestinal tract without being broken down or absorbed in significant amounts, remaining as particulate matter.
A small subset of individuals with exceptionally high seafood intake accumulate microplastic particles at rates that exceed population averages, leading to extreme daily exposure levels.
Estimated exposure values at the upper percentiles are derived from statistical models that extrapolate consumption patterns beyond directly observed data, potentially inflating peak estimates.
