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.
Identification and Characterization of Micro and Mesoplastics Isolated from Commercially Important Marine Fishes of Pulicat Lake, Tamil Nadu, India
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.
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.
Identification and Quantification of Microplastics in Mackerel (Rastrelliger sp) at the Tual City Fish Market
Researchers identified and quantified microplastics in the digestive tracts of mackerel from the Tual City fish market in Indonesia using microscopy and FTIR analysis, confirming the presence of multiple polymer types in commercially sold fish.
Plastic in digestive tracts and gills of cod and herring from the Baltic Sea
Researchers found plastic particles in the digestive tracts and gills of Baltic Sea cod and herring, with ingestion rates and particle types differing between the two species, indicating widespread exposure of commercially important fish to plastic pollution.
Microplastics in eviscerated flesh and excised organs of dried fish
This study detected microplastics in both the eviscerated flesh and excised organs of four commonly consumed dried fish species, using Raman spectroscopy for polymer identification. The finding raises food safety concerns because it suggests microplastics can be present even in the edible portions of commercially sold fish.
Microplastics Determination in Gastrointestinal Tracts of European Sea Bass (Dicentrarchus labrax) and Gilt-Head Sea Bream (Sparus aurata) from Tenerife (Canary Islands, Spain)
Researchers examined microplastics in the gastrointestinal tracts of 86 farmed European sea bass and gilt-head sea bream from Tenerife, finding that most items were colorless and blue microfibers averaging around 2 mm in length. FTIR analysis revealed cellulosic fibers as the most common type, followed by polyester, polyacrylonitrile, and poly(ether-urethane).
Quantification and characterization of microplastics in commercial fish from southern New Zealand
Researchers quantified microplastic ingestion in ten commercially important fish species from southern New Zealand using microscopy and Raman spectroscopy. The study found that 75% of fish contained microplastics, with an average of 2.5 particles per fish, predominantly fibers in blue, black, and red colors, composed mainly of polyester and polyethylene terephthalate.
Microplastics in seawater and fish acquired from the corresponding fishing zones of the Baltic Sea
Microplastics were detected in 100% of seawater and 61% of fish samples collected from corresponding fishing zones of the Baltic Sea, with mean abundances of 19,984 items/m³ in seawater and 3.3 items per fish. The co-sampling design linking fish MP loads to their water column environment provided direct evidence of aquatic exposure driving tissue contamination.
Validation of an imaging FTIR spectroscopic method for analyzing microplastics ingestion by Finnish lake fish (Perca fluviatilis and Coregonus albula)
Researchers developed and validated an imaging FTIR spectroscopy method for identifying microplastics ingested by Finnish lake fish, including perch and vendace. The study confirmed that wild freshwater fish are ingesting microplastics and demonstrated that standardized analytical methods are needed to improve the reliability of microplastic detection in aquatic organisms.
Sources and fate of microplastics in marine and beach sediments of the Southern Baltic Sea—a preliminary study
Researchers investigated microplastic sources and distribution in marine and beach sediments of the southern Baltic Sea — one of the most polluted regional seas — using density extraction and FT-IR identification. The study found widespread contamination with significant variability tied to local sources and hydrodynamic transport patterns.
Microplastic ingestion by small coastal fish in the northern Baltic Sea, Finland
