Microplastic fibers in the gut of highly consumed fish species from the southern Caspian Sea
AI summary Read the abstract
Researchers assessed microplastic contamination in the guts of three highly consumed fish species from the southern Caspian Sea. They found that fibers were the only shape of microplastics detected, with leaping mullet showing the highest frequency, and that black-colored polystyrene, polypropylene, and polyethylene terephthalate were the dominant polymer types across all species.
This study assesses the frequency, distribution, characteristics, and chemical composition of microplastics (MPs) in the gut of highly consumed fish species, namely leaping mullet (Chelon saliens), common carp (Cyprinus carpioi), and Caspian kutum (Rutilus caspicus), in the southern Caspian Sea biome. Fibers are found to be the only shape of MPs. Black MPs and polystyrene, polypropylene, and polyethylene terephthalate polymers are dominant. MP frequency is highest in leaping mullet's gut, while kutum specimens exhibited the lowest MP frequency, reflecting that leaping mullet is a neritic species and thus highly exposed to MP influx in shallow coastal water, while the other species are benthopelagic. The estimated condition index reflected a significant difference between the species, implying that MPs may pose adverse health impacts on leaping mullet and common carp, with no undesirable effect on Caspian kutum. No significant relationship exists between biological parameters and the MP frequency in the fish gut.

Microplastics in commercial fish and their habitats in the important fishing ground of the Black Sea: Characteristic, concentration, and risk assessment
AI summary Read the abstract
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.

Researchers examined plastic ingestion in seven commercial fish species from the Black Sea and found plastics in the gastrointestinal tracts of 29% of all individuals tested. Fibres were the most common type of plastic found, accounting for nearly 69% of all particles, with 93% being microplastics smaller than 5 mm. The study identified polypropylene, polyester, and acrylic as the most prevalent polymer types, indicating widespread microplastic contamination in Black Sea commercial fisheries.
