The first report on the occurrence of microplastics in commercial fish species and surrounding water from the Baltic Sea (Poland)
Summary
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 (MP) are emerging pollutants that have been found in different environmental matrices of marine and coastal ecosystems, where they can generate harmful ecological impacts. However, the relationship between MP in organisms and their habitats remains relatively poorly understood. The Baltic Sea is a semi-enclosed intracontinental sea, particularly exposed to pollution by MP due to limited water exchange with the North Sea. A comprehensive study of the abundance and characteristics of MP in seawater and fish in the Baltic Sea was performed for the first time. Seawater samples (surface water and water column) were collected in the south Baltic Proper, Gulf of Gdańsk, and Gotland Basis. The fish were caught as bycatch of baltic herring by a commercial fishing vessel within area 27 FAO Major Fishing Area for statistical purposes, sub-area IIID. MP were detected in 100 Also see: https://micro2024.sciencesconf.org/556553/document

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 occurrence in commercial fish species and surrounding water from the Polish Baltic Sea, characterizing particle abundance and properties while examining the poorly understood relationship between microplastic concentrations in organisms and their surrounding habitat.
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.
Comparative study on microplastic abundance in fish organs from marine and freshwater ecosystems of the southern Baltic Sea region: influence of habitat zone and feeding preferences
Researchers found microplastics in 58% of 500 fish specimens examined across Baltic Sea and northern Polish freshwater ecosystems, with carnivorous and benthic species showing the highest contamination levels and blue fibers being the most common particle type across all habitats.
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 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.
