Abstract: The study of microplastic content in water, sediments, gills and gastrointestinal tract of bream (Abramis brama) at the mouth of the Mesha River, the right tributary of the Kama River, was conducted. The content of microplastics in water was found at the level of 20.5 ± 22.3 units/m3, in bottom sediments 44.7 ± 41.8 units/kg, in fish gills 12.3 ± 8.4 units/example, in the gastrointestinal tract 14.5 ± 11.5 units/example. Fibers dominated in water samples, in the gills and gastrointestinal tract of fish, fragments dominated in the sediment. Correlation analysis showed the presence of a negative relationship between the content of microplastics in the gills, gastrointestinal tract and biologic indicators of studied fish. In terms of the frequency of occurrence and content of microplastics in the gills and gastrointestinal tract, the contamination of the studied fish is at a high level compared to literature data, which is associated with the feeding behavior of bream.
