This study identified micro- and mesoplastics in the digestive tracts of 15 commercially important fish species from an Indian coastal lake, using infrared spectroscopy to confirm plastic polymer types. The presence of plastics in food fish raises concerns about human dietary exposure through seafood consumption.
Concentration and Characterisation with Spectroscopic Technique of Microplastics in the Surface Sediment and Commercial Fish Species of Gemlik Bay (Marmara Sea)
Researchers surveyed microplastic contamination in sediment and commercial fish in Gemlik Bay in the Marmara Sea, Turkey, finding widespread contamination with fibres as the dominant type and higher concentrations near the harbour. Because several of the fish species sampled are commonly eaten, the results point to a direct route of microplastic exposure for people consuming seafood from this region.

Microplastics in Commercial Fishes and By-Catch from Selected FAO Major Fishing Areas of the Southern Baltic Sea
Researchers found microplastics in both edible and non-edible organs of five fish species from the southern Baltic Sea, with 1-12 particles per fish dominated by fibers, and polymers including cellophane, polyamide, polyethylene, and polypropylene identified by FTIR spectroscopy.
Determination of Microplastic Pollution in Commercial Fish in the Middle Black Sea (Samsun), Türkiye
Researchers detected microplastics in six commercially important fish species from the Middle Black Sea Region, including rainbow trout, sea bass, sea bream, red mullet, horse mackerel, and whiting. MPs were found in multiple species, with polymer type and shape varying by species and habitat, reflecting differences in feeding behavior and habitat exposure.
Screening of Microplastics in Aquaculture Systems (Fish, Mussel, and Water Samples) by FTIR, Scanning Electron Microscopy–Energy Dispersive Spectroscopy and Micro-Raman Spectroscopies
Researchers screened for microplastics in fish, mussels, and water from aquaculture farms using multiple detection methods. Microplastics were found in both farmed fish and mussels, which are widely sold for human consumption. This study highlights that aquaculture systems are not free from microplastic contamination, meaning farmed seafood, like wild-caught fish, is a potential source of microplastic exposure for people.
Microplastics Contamination of Mackerel and Red Snapper as Commercial Fish from the Takalar Fish Landing, Indonesia
Researchers identified and characterized microplastics from mackerel and red snapper tissues collected at the Takalar Fish Landing, Indonesia, using FTIR spectroscopy to confirm polymer types after counting particles by shape, size, and color, while implementing contamination-prevention protocols to ensure result accuracy.
Microplastic Contamination in Farmed Rainbow Trout (Oncorhynchus mykiss): First Evidence from Bulgarian Freshwater Aquaculture
Researchers present the first assessment of microplastic contamination in farmed rainbow trout muscle tissue from Bulgarian freshwater aquaculture. Using advanced infrared imaging spectroscopy, they detected microplastics in all examined fish, with multiple polymer types suggesting diverse contamination sources. The findings underscore the importance of monitoring microplastic levels in aquaculture species intended for human consumption.
Microplastic litter composition of the Turkish territorial waters of the Mediterranean Sea, and its occurrence in the gastrointestinal tract of fish
Researchers analyzed microplastic litter composition in Turkish territorial waters of the Mediterranean, documenting polymer types, shapes, and sizes and identifying textiles and packaging as dominant plastic sources.
Microplastics FTIR characterisation and distribution in the water column and digestive tracts of small pelagic fish in the Gulf of Lions
Researchers found microplastics in 93% of water column samples and in 12% of sardines and 11% of anchovies sampled from the Gulf of Lions in the NW Mediterranean Sea, characterizing plastic composition by FTIR and finding similar debris types in both water and fish digestive tracts.
Ingested Microplastics in 18 Local Fish Species from the Northwestern Mediterranean Sea
Researchers investigated microplastic occurrence and polymer composition in the digestive tracts of 18 coastal fish species from the northwestern Mediterranean Sea, using hydrogen peroxide digestion and FTIR spectrometry with rigorous blank controls, which led to removing 78% of initially suspected particles. Corrected microplastic concentrations ranged from 0.00 to 5.15 items per fish, consistent with other Mediterranean studies, with polymer type variation across species.
Comparative analysis of microplastic pollution in commercially relevant seafood across different geographical regions
This study compared microplastic contamination across commercially relevant seafood species commonly consumed in the European market, characterizing both the morphological and chemical properties of particles found in edible tissue. Results showed widespread but variable contamination across species, with polymer types and particle abundance differing by species and tissue type.
Abundance and characteristics of microplastics in commercial marine fish from Malaysia
Microplastics were found in the digestive tracts of eight commercially important marine fish species caught in Malaysian waters, with prevalence and particle types varying by species and location. The study raises food safety concerns for Malaysian seafood consumers and highlights the widespread occurrence of microplastic ingestion in wild-caught fish from Southeast Asian seas.
Microplastics’ Occurrence in Edible Fish Species (Mullus barbatus and M. surmuletus) from an Italian Marine Protected Area
Researchers assessed microplastic contamination in the gastrointestinal tracts and livers of red mullet species (Mullus barbatus and M. surmuletus) from a Marine Protected Area in the Ionian Sea, finding microplastics in over 60% of specimens at an average of three items per fish. ATR-FTIR and pyrolysis-GC/MS identified the dominant polymer types, with red mullets showing nearly twice the contamination levels of striped red mullets.
Screening for microplastics in marine fish of Thailand: the accumulation of microplastics in the gastrointestinal tract of different foraging preferences
Researchers investigated microplastic ingestion in 492 marine fish (361 demersal and 131 pelagic) from Thailand, finding no significant difference in uptake between the two foraging types, with polyamide fibers dominating in both groups. FT-IR analysis confirmed polyamide as the most common polymer and red-colored fibers as the most abundant morphology, providing the first such characterization for Thai marine fish.
Microplastic 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.
