Determination of the amount of microplastic found in Osmerus eperlanus caught in the Neva river
AI summary Read the abstract
This study measured the amount of microplastic in smelt (Osmerus eperlanus) caught from the Neva River near St. Petersburg, Russia, using validated extraction and identification methods. The research highlighted microplastic contamination in a commercially important freshwater fish species consumed by humans.
This study draws attention to the current problem of pollution of aquatic ecosystems with microplastics and its potential impact on humans through food products. The level of microplastics in smelt Osmerus eperlanus , caught from the Neva River in St. Petersburg, was assessed. The research methodology included collecting fish samples and examining their internal organs and muscle fibers for the presence of microplastics. The results showed that microplastic particles were present in all samples examined, especially in female smelt. The study also found the presence of microplastics in the muscles of the fish, indicating the possibility of their entry into the human body through fish consumption.

Presence of microplastic in the digestive tracts of European flounder, Platichthys flesus, and European smelt, Osmerus eperlanus, from the River Thames
AI summary Read the abstract
Researchers found microplastics in the digestive tracts of both European flounder and European smelt from the River Thames in London, with occurrence rates reflecting the fish's benthic versus pelagic feeding habits. The study demonstrates that fish in heavily urbanized river systems are exposed to microplastic contamination through their diet.

AI summary Read the abstract
Researchers examined microplastic contamination in fish from the Neva River and Lake Ladoga in Russia, situating the findings within the global context of widespread plastic pollution in aquatic ecosystems. The study highlighted the difficulty of natural plastic decomposition and the ongoing accumulation of microplastics in freshwater systems, with UNESCO estimates of 8-10 million tonnes entering seas annually.
The first observation of the presence of microplastics in wild common bleak (Alburnus alburnus L.) and standardization of extraction protocols
AI summary Read the abstract
Researchers studied microplastic contamination in the digestive tracts, muscle tissue, and whole bodies of common bleak fish from a Serbian reservoir, comparing different extraction protocols. The study provides first evidence of microplastics in this species while also developing cost-effective extraction methods.
Microplastic Content in the Gastrointestinal Tract of Some Fish Species of Lake Kubenskoe (Vologda Oblast)
AI summary Read the abstract
Researchers quantified microplastic content in the gastrointestinal tracts of perch, roach, and bream from Lake Kubenskoe in the Vologda region of Russia, representing the first evidence of microplastic contamination in fish from Vologda Oblast water bodies. MPs were detected in 60% of bream and 43% of perch individuals but not in roach, with average loads of 1.6 particles per bream and 4.2 particles per perch, predominantly in fiber form.
Microplastics in gudgeon (Gobio gobio) and roach (Rutilus rutilus) from a Central European small river
AI summary Read the abstract
Microplastics were investigated in gudgeon and roach fish species collected from a small Central European river, contributing data on freshwater fish exposure in inland waterways. The study adds to the growing evidence that microplastic ingestion by freshwater fish is widespread across European river systems.
