ClearMicroplastic occurrence in the gastrointestinal tract and gill of bioindicator fish species in the northeastern Mediterranean
Four commercial fish species from the northeastern Mediterranean were examined for microplastic presence in gastrointestinal tracts and gills, with plastics found in all species and fiber being the most common type. The results add to growing evidence that microplastic ingestion is routine for commercially harvested Mediterranean fish.
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.
Assessment of microplastic pollution in eleven commercial fish species in the Gulf of İzmir (Aegean Sea, eastern Mediterranean)
Researchers examined 152 fish from 11 commercially important species in the Gulf of Izmir, Turkey, and found microplastics in 42% of them. Polyethylene fragments and fibers were the most common types found in fish digestive tracts, with surface-dwelling fish species showing higher contamination than bottom-dwelling ones. Since these are species commonly sold and eaten by people in the region, the study highlights a direct pathway for microplastic exposure through seafood consumption.
Microplastics in commercial fish and their habitats in the important fishing ground of the Black Sea: Characteristic, concentration, and risk assessment
Researchers analyzed microplastic contamination in six commercial fish species from the Black Sea and found microplastics in all environmental areas studied, including surface water, the water column, sediments, and fish. Fibers were the most common type of microplastic found, and bottom-dwelling fish had higher contamination levels than fish living closer to the surface. Since these are commonly eaten fish species, the findings are relevant to human dietary exposure to microplastics.
Microplastic Concentration in Mediterranean Commercial Fish: A Systematic Review

Researchers analyzed fillets of several common Mediterranean seafood species for microplastic contamination and estimated the associated human dietary exposure. They detected microplastics in the edible tissue of all species tested, including sardines, sea bream, and mussels. The study provides risk estimates suggesting that regular seafood consumption represents a notable pathway for human microplastic ingestion.
Occurrence, distribution and characteristics of microplastics in gastrointestinal tract and gills of commercial marine fish from Malaysia
Researchers examined 158 commercial marine fish from 16 species in Malaysia and found microplastics in the gastrointestinal tracts and gills of all species studied. Fibers were the most common microplastic type, and the contamination levels varied between sampling locations. The findings add to growing evidence that microplastics are widespread in commercially important fish species, raising questions about the potential for human exposure through seafood consumption.
Abundance and distribution of environmental microplastic in edible fish and mussels from the south Mediterranean coasts
Scientists found microplastics in every fish and mussel sample examined from the Algerian Mediterranean coast, with six common plastic types identified including polypropylene and polyethylene. The contaminated species are widely consumed by local populations. This study adds to growing evidence that people eating seafood are regularly exposed to microplastics, and helps establish baseline pollution data for an understudied region.
Microplastic accumulation in commercial fish from the Adriatic Sea
Researchers assessed microplastic contamination in six commercial fish species from the Northern Adriatic Sea sold for human consumption. The study found that 47.8% of fish contained microplastics, primarily polyethylene and polypropylene fragments, which is particularly concerning because some of these species are consumed whole without being gutted.
Distribution, abundance, and composition of microplastics in market fishes from the Red and Mediterranean seas in Egypt
Researchers analyzed microplastic contamination in commercially sold fish from both the Mediterranean and Red seas in Egypt and found microplastics in 88 percent of the fish examined. Fibers were the most common particle type, and species that feed closer to the seafloor tended to have higher contamination levels. The study raises concerns about human dietary exposure to microplastics through regularly consumed market fish in the region.
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.
Detection of fibrous microplastics and natural microfibers in fish species (Engraulis encrasicolus, Mullus barbatus and Merluccius merluccius) for human consumption from the Tyrrhenian sea
Scientists examined the gut contents of three popular fish species from the Tyrrhenian Sea sold in markets and found microfibers in all of them. While natural and artificial fibers were the most common, synthetic plastic fibers including polyester were also present. Since these are fish people regularly eat, the study highlights seafood as a pathway for human microplastic exposure and calls for better standardized methods to assess the risk.
Microplastics in Morocco's most consumed fisheries: Chemical characterization, ecological traits, and implications for human health
Researchers analyzed 240 fish from 12 of Morocco's most commonly consumed species and found microplastics in 100% of samples, with particles detected in the gills, gonads, and digestive tracts. The most common plastics were polyethylene, PET, and polypropylene, predominantly appearing as fragments and fibers smaller than 1 mm. The findings raise concerns about human exposure to microplastics and associated heavy metals through everyday seafood consumption.
Occurrence of microplastics in the gastrointestinal tracts of four most consumed fish species in Giresun, the Southeastern Black Sea
Researchers examined four commonly eaten fish species from the Black Sea coast of Turkey and found microplastics in the digestive tracts of all four species. Bottom-dwelling fish had higher microplastic concentrations than surface-dwelling species, likely because microplastics settle and accumulate in sediments. Since these are popular commercial fish species, the findings underscore a direct route of microplastic exposure for seafood consumers in the region.
Microplastic contamination in thirty commercially important fish species: Distribution, polymer composition, pollution indices, and human health risks
Researchers examined microplastic contamination in 600 specimens across 30 commercially important fish species from the Indian coast, finding the highest accumulation in the gastrointestinal tract with carnivorous species carrying the greatest burden. Polyethylene and polypropylene fibers were the dominant particle types, and human health risk assessment showed measurable daily intake from consuming these fish, with pollution indices indicating considerable to medium hazard risk levels.
Relationship between biological, ecological parameters and microplastic concentration in Mediterranean fish species
