The first report on the occurrence of microplastics in commercial fish species and surrounding water from the Baltic Sea (Poland)
Researchers conducted the first comprehensive study of microplastic contamination in both seawater and commercial fish species from the Baltic Sea, collecting surface and water-column samples from multiple sub-regions and examining fish caught as bycatch of Baltic herring, finding microplastics were detected in 100% of fish examined.
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.
Plastic contamination of sandy beaches along the southern Baltic – a one season field survey results
Researchers surveyed microplastic and macroplastic contamination along the Polish Baltic Sea coast, finding microplastic concentrations of 118–1,382 pieces/kg in beach sand and 0.61–2.76 pieces/dm3 in coastal waters, with sub-1 mm blue fibers dominating across all sites and suggesting a common fibrous source throughout the Polish coastal zone.
Occurrence and characterization of microplastic content in the digestive system of riverine fishes
Researchers found microplastics in 93.8% of riverine fish examined, with polystyrene, polyethylene, and nylon being the most common polymer types concentrated near urban and industrial areas, and small particles (0.025-1 mm) predominating across species.
Worldwide contamination of fish with microplastics: A brief global overview
A literature review from March 2019 to March 2020 synthesized worldwide data on microplastic contamination in fish, finding that a median of 60% of fish from 198 species across 24 countries contained microplastics in their organs. Carnivorous species ingested more microplastics than herbivores, consistent with trophic transfer and bioaccumulation through food webs.
Characteristics and retention of microplastics in the digestive tracts of fish from the Yellow Sea
Researchers systematically characterized microplastics in 19 fish species from the Yellow Sea coast of China, finding plastic retention in 34% of individual fish sampled, with fibers dominating and significant variation in microplastic load by species and habitat.
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.
Microplastic ingestion by small coastal fish in the northern Baltic Sea, Finland
Researchers found microplastics in 9% of 424 small coastal fish examined in the northern Baltic Sea, with urban Helsinki sites showing the highest prevalence (27.5%), and no relationship found between fish size or species and microplastic ingestion, suggesting coastal urbanization as a key driver.
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.
Abundance, characteristics and variation of microplastics in different freshwater fish species from Bangladesh
Researchers examined 48 freshwater fish from 18 species in Bangladesh and found microplastics in the digestive tracts of over 73% of the fish studied. Fibers were the most common shape, and the plastics were primarily polyethylene and polypropylene-based polymers. Bottom-dwelling fish contained more microplastics than those living higher in the water column, suggesting that contaminated sediments are a significant source of exposure for freshwater species.
Microplastic Intake, Its Biotic Drivers, and Hydrophobic Organic Contaminant Levels in the Baltic Herring
Researchers investigated microplastic ingestion and hydrophobic organic contaminant levels in Baltic herring along the Swedish west coast, finding microplastics in 22.3% of fish with large geographic variability, though no significant correlation was found between microplastic burden and contaminant concentrations in muscle tissue.
Characterization and enumeration of microplastic pollution in three fish species of the Upper Mississippi River
Researchers found 891 microplastic particles across 281 fish from three species in the Upper Mississippi River, with fibers being the most common type and smaller fish containing proportionally more microplastics than larger ones. This confirms microplastic ingestion is widespread in freshwater fish — not just marine species — and the presence of styrene-isoprene, polyester, and ABS polymers highlights the diverse plastic sources contaminating major river systems.
Microplastics in freshwater fish from Central European lowland river (Widawa R., SW Poland)
More than half of gudgeon and roach fish collected from a small Polish river had ingested microplastic-like particles, with no significant difference by sex, feeding behavior, or location relative to a dam. The findings suggest microplastic ingestion by freshwater fish is widespread and not driven by a single local source.
Microplastics in Polish freshwater ecosystems: Current state of knowledge and research gaps
This review compiled and compared data on microplastic contamination in Polish freshwater ecosystems, analysing 65 aquatic systems (47 lakes, 13 rivers, and others) based on studies published up to 2024 to identify the current state of knowledge and research gaps.
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.
Occurrence of microplastics (MPs) in the gastrointestinal tract of fishes: A global systematic review and meta-analysis and meta-regression
Fish globally averaged 2.76 microplastic particles per gastrointestinal tract, with fish from enclosed water bodies (lakes, estuaries) containing 2-4x more than those from open oceans, and fish from low-income economies harboring 5.5x more microplastics than those from high-income economies.
Prevalence of Fibers as the Dominant Microplastic Fraction in the Digestive Tract of Three Commercially Important Fish Species (Sparus aurata Linneaeus 1758, Pagellus erythrinus Linneaeus 1758 and Chelon auratus Risso, 1810) from the Southeastern Coast of Istria, Northern Adriatic, Croatia
This study examined the digestive tracts of multiple marine organisms and found that synthetic fibers were the dominant microplastic type, making up the majority of particles found across species. The prevalence of fibers reflects the large contribution of textile washing to aquatic microplastic burdens.
Microplastics pollution in freshwater fishes in the South of Italy: Characterization, distribution, and correlation with environmental pollutants
Researchers investigated the presence, abundance, and polymer composition of microplastics in the gastrointestinal tracts of freshwater fish from rivers in southern Italy, and evaluated correlations between microplastic ingestion and environmental pollutant levels. They found microplastics in multiple fish species, with fiber morphologies predominating, and identified associations between microplastic burden and co-occurring chemical contaminants in the sampled environments.
Abundance, characteristics, and risk assessment of microplastics in indigenous freshwater fishes of India
Researchers examined microplastic contamination in five widely consumed freshwater fish species from India and found plastic particles in all specimens, with fibers being the most dominant type. Evidence of microplastics in edible fish tissue indicates translocation from the gut, suggesting a pathway for human exposure through consumption. Risk assessment showed that while microplastic abundance posed a low quantitative risk, the polymer types identified indicated a high hazard potential for the fish species studied.
Occurrence and potential effects of plastic ingestion by pelagic and demersal fish from the North Sea and Baltic Sea
Researchers examined the occurrence and potential effects of plastic ingestion in pelagic and bottom-dwelling fish from the North Sea and Baltic Sea, finding plastics in both groups. The study contributed to baseline knowledge of microplastic ingestion rates in commercially important fish species in European seas.
Microplastic prevalence in marine fish from onshore Beibu Gulf, South China Sea
Researchers examined 271 fish across 32 species from the Beibu Gulf and found microplastics in the majority of samples, with fibers being the most common type and abundance varying by species, feeding habits, and habitat.
Plastic ingestion by pelagic and demersal fish from the North Sea and Baltic Sea
Researchers examined gastrointestinal tracts of 290 North and Baltic Sea fish and detected plastic in 5.5% of individuals, with pelagic species like herring and mackerel ingesting plastic at three times the rate of bottom-dwelling cod and flounder, and polyethylene making up nearly 40% of identified polymer types.
A meta-analysis of the characterisations of plastic ingested by fish globally
This meta-analysis pools data from global studies to assess what types of plastic fish most commonly ingest, finding that microfibers and small fragments dominate across both freshwater and marine species. These findings are important for human health because widespread plastic ingestion by fish means that microplastics are likely present in much of the seafood consumed around the world.
