Examining 11 fish species and 6 benthic invertebrate species collected during 2019-2020, the study evaluated resident marine fauna as monitors of microplastic contamination.
Micro-and macro-plastics in marine species from Nordic waters
This study surveyed micro- and macro-plastic contamination in marine species collected from Nordic waters, finding plastic in fish, crustaceans, and seabirds from multiple locations. The results document the geographic extent of microplastic ingestion across commercially and ecologically important Nordic marine species.
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 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.
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 and spatial distribution of microplastics in the surface waters of the Baltic Sea and the Gulf of Riga
Microplastic abundance and composition were compared between the Gulf of Riga and the Eastern Gotland Basin of the Baltic Sea, with higher concentrations in the Gulf of Riga near river mouths and urban coasts, and polypropylene and polyethylene dominating the polymer composition at most sites.
Screening for microplastics in sediment, water, marine invertebrates and fish: Method development and microplastic accumulation
Researchers developed improved methods for extracting microplastics from biological samples and sediments, using enzymatic digestion that achieved 97% particle recovery without damaging the plastics. When applied to field samples from the North Sea and Swedish coast, they found microplastics in 8 of 9 invertebrate species tested and in 68% of brown trout. Mussel tissue contained roughly a thousand times more microplastic particles per kilogram than surrounding sediment or water.
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.
Microplastic contamination of sandy beaches of national parks, protected and recreational areas in southern parts of the Baltic Sea
Researchers found microplastic contamination in all 51 surface beach sand samples across seven sites along the southern Baltic Sea, including national park and protected areas, at a mean of 68 items/kg dry weight. Expanded polystyrene fragments were the most common type (~38%), and protected areas did not differ substantially from recreational beaches.
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.
Microplastics in Surface Waters of the Russian Arctic Seas: Distribution, Concentration, Identification, and Eco-Risks for Fish
Microplastics were detected across surface waters of the Russian Arctic seas, with concentrations and polymer types varying by region and season. The findings document that even high-latitude Arctic waters are not spared from microplastic contamination, likely transported by ocean currents and rivers.
Well-Being of the Baltic Herring and Bycatch Fish Species from FAO Major Fishing Areas 27 According to Microplastic Pollution
Researchers assessed the well-being of Baltic herring and bycatch species using condition factors and novel gill and gut indices, finding microplastics in all species examined, with contamination rates ranging from 21 to 79 percent. Fish from different basins showed varying condition scores and microplastic burdens, though no consistent negative correlation between microplastic presence and fish health was established. The study provides baseline data for monitoring how microplastic pollution may affect commercially important fish populations in the Baltic Sea.
