ClearMicroplastic distribution in different tissues of small pelagic fish of the Northeast Atlantic Ocean
Researchers analyzed microplastic contamination in three commercially important fish species from the Atlantic coast of the Iberian Peninsula, finding plastic particles in the gut, gills, and muscle tissue. Horse mackerel had the highest contamination rates, with 92 percent of individuals containing microplastics in their digestive tract and 63 percent in their muscle. Since these fish are widely consumed by people, the presence of microplastics in edible muscle tissue is a direct concern for human dietary exposure.

Microplastics in the stomach content of the commercial fish species Scomber colias in the Gulf of Cadiz, SW Europe
Scientists examined the stomachs of 104 Atlantic chub mackerel from the Gulf of Cadiz and found that over 90% contained microplastics, with an average of about 5 particles per fish. Fibers made up 91% of the microplastics found, and the most common polymer was polyamide (nylon). Since this mackerel species is widely consumed by people, the consistent presence of microplastics in their stomachs raises questions about how much plastic is transferred to humans through seafood.
Suspected microplastics in Atlantic horse mackerel fish (Trachurus trachurus) captured in Portugal

Microplastic ingestion by Atlantic chub mackerel (Scomber colias) in the Canary Islands coast
Researchers examined 120 Atlantic chub mackerel from the Canary Islands and found that 78.3 percent had microplastics in their digestive tracts. Fibers were the most common type of microplastic found, followed by plastic fragments and paint particles. The study represents the first investigation of microplastic contamination in fish from the Northwest African upwelling system, suggesting that this commercially important species could serve as an indicator for microplastic pollution in the region.
Occurrence of microplastics in the gastrointestinal tract of pelagic and demersal fish from the English Channel
Researchers examined the gastrointestinal tracts of both pelagic and demersal fish species and found microplastics in individuals from both groups, suggesting that microplastic ingestion occurs across fish species regardless of their position in the water column.
Microplastics occurrence in edible fish species (Mullus barbatus and Merluccius merluccius) collected in three different geographical sub-areas of the Mediterranean Sea
Researchers examined the gastrointestinal tracts of 229 demersal fish from two Mediterranean species across three geographic sub-areas, finding microplastics in a significant portion of individuals with fibers as the dominant type. The study contributes to growing evidence that microplastic ingestion is widespread in commercially fished Mediterranean species.
Occurrence of microplastics in fishes from two landing sites in Tuticorin, South east coast of India
Microplastics were found in the stomachs of two commercial fish species from markets in Tuticorin on India's southeast coast, with fibers and fragments as the dominant types. The study provides baseline data on microplastic ingestion by market fish in a major Indian fishing hub with implications for human dietary exposure.
Occurrence of microplastics in the gastrointestinal tracts of some edible fish species along the Turkish coast
Researchers examined the gastrointestinal tracts of 243 individual fish from five edible species along the Turkish coast, documenting the occurrence and characteristics of ingested microplastics. The study found microplastics present in multiple commercially important fish species, raising implications for seafood safety and human dietary exposure.
