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.

Microplastics in freshwater fish from Central European lowland river (Widawa R., SW Poland)
AI summary Read the abstract
More than half of gudgeon and roach fish collected from a small Polish river had ingested microplastic-like particles, with no significant difference by sex, feeding behavior, or location relative to a dam. The findings suggest microplastic ingestion by freshwater fish is widespread and not driven by a single local source.
Microplastic contamination in gudgeons (Gobio gobio) from Flemish rivers (Belgium)
AI summary Read the abstract
Researchers found microplastic contamination in gudgeons (Gobio gobio) from Flemish rivers in Belgium, contributing early evidence of microplastic ingestion in European freshwater fish and highlighting the need for greater attention to plastic pollution in freshwater ecosystems.
Wild gudgeons (Gobio gobio) from French rivers are contaminated by microplastics: Preliminary study and first evidence
AI summary Read the abstract
Researchers found microplastics in the digestive tracts of wild gudgeons caught from multiple French rivers, with 12% of individuals contaminated. This field study confirms that freshwater fish in European rivers are exposed to real-world microplastic contamination through their natural foraging behavior.
Microlitter measurement in fish Rutilus rutilus from the Slovenian part of the Mura river basin
AI summary Read the abstract
Researchers examined the gastrointestinal tracts of 50 common roach caught from the Slovenian portion of the Mura River basin, conducting the first study of microlitter contamination in Slovenian freshwater fish and characterizing the abundance, morphology, and polymer types of ingested particles.
Microplastics in the Danube River and Its Main Tributaries—Ingestion by Freshwater Macroinvertebrates
AI summary Read the abstract
Researchers measured microplastic concentrations in the Danube River and its major tributaries and analyzed ingestion by freshwater fish species collected from multiple sites. Microplastics were detected in a significant proportion of fish, with ingestion rates correlating with local plastic contamination levels, documenting widespread plastic exposure across the Danube watershed's fish communities.
