Microplastic contamination in edible marine fishes from the upper Gulf of Thailand

Researchers examined microplastic contamination in edible fish from the upper Gulf of Thailand and found that nearly half the fish sampled contained microplastics in their digestive tracts, mostly polyester fibers. The estimated daily microplastic exposure for people eating these fish was relatively low at 0.03 to 0.1 particles per person. While the immediate risk appears small, the study recommends continued monitoring to ensure seafood safety as plastic pollution increases.

Low prevalence of microplastic contamination in planktivorous fish species from the southeast Pacific Ocean

Researchers examined the gut contents of 292 planktivorous fish from seven species along the southeast Pacific coast and found a very low prevalence of microplastic contamination, with only 2.1% of fish containing plastic particles. The microplastics found were degraded fragments and threads of various colors, suggesting the fish were not selectively targeting them. The study indicates that microplastic ingestion risk for planktivorous species in this region may currently be limited compared to other ocean areas.

Does the microplastics ingestion patterns and polymer composition vary across the oceanic zones? A case study from the Indian coast

Researchers examined microplastic ingestion in 27 species of deep-sea fish from the Central Indian Ocean and found contamination in 19 of them, with PET being the most common polymer. The study suggests that feeding behavior, rather than habitat depth or trophic level, is the primary factor influencing how much microplastic deep-sea fish ingest, and proposes these fish could serve as indicators for monitoring deep-sea plastic pollution.

Deposition characteristics of microplastics in coral reef fish with different feeding habits from the Xisha Islands Waters, South China Sea

Researchers examined microplastic contamination in the gills and gastrointestinal tracts of 96 coral reef fish from the South China Sea, finding that nearly 98% of sampled fish contained microplastics. Fibers were the most common shape, with most particles smaller than 1 mm, and the predominant polymers were PET, PE, and PP. The study found that herbivorous fish had higher microplastic content than omnivorous or carnivorous species, likely because they feed primarily on microplastic-polluted coral reefs.

Occurrence and accumulation of microplastics in commercial fish in the coastal waters of the Lvsi fishing ground in China

Researchers examined microplastics in the gills and guts of 11 commercial fish species from a Chinese coastal fishing ground, finding that over 85% of fish contained microplastics in these tissues at levels of roughly 2–3 pieces per fish. PET fibers with a blue color were most common, and microplastic abundance did not increase with trophic level, suggesting limited biomagnification in this food web. Because many of these fish species are consumed by humans, understanding their microplastic loads is directly relevant to assessing human dietary exposure.
