Microplastic Pollution in Leuciscus baicalensis and Rutilus rutilus: An Impending Danger to Aquatic Biodiversity in Western Siberian Riverine Fishes
AI summary Read the abstract
Microplastic contamination was documented in two freshwater fish species -- Leuciscus baicalensis and Rutilus rutilus -- from rivers in Western Siberia, adding to evidence that microplastic pollution threatens aquatic biodiversity in remote regions.
Microplastic pollution is increasingly recognized as a significant threat to aquatic ecosystems and human health, prompting growing concern among environmental scientists [...]

Microplastic ingestion by fish with different feeding habits in the Ob and Yenisei Rivers
AI summary Read the abstract
Microplastic particles (0.15-5.0 mm) were found in 62% of 141 freshwater fish examined from the Ob and Yenisei rivers in Siberia, with prevalence ranging from 18.5% in Yenisei perch to 92.6% in Ob ruffe. Fibers accounted for up to 99.7% of all detected particles across the three fish species studied.
Microplastic Pollution in the Surface Waters from Plain and Mountainous Lakes in Siberia, Russia
AI summary Read the abstract
Researchers conducted the first analysis of microplastic pollution in six lakes across southern Siberia, including both mountainous and plain environments. Microplastics were detected in all lakes studied, even those in protected areas with no permanent population nearby. The findings indicate that microplastic contamination has reached remote freshwater environments in Siberia, highlighting the widespread nature of this pollution.
Microplastics in Surface Waters of the Russian Arctic Seas: Distribution, Concentration, Identification, and Eco-Risks for Fish
AI summary Read the abstract
Microplastics were detected across surface waters of the Russian Arctic seas, with concentrations and polymer types varying by region and season. The findings document that even high-latitude Arctic waters are not spared from microplastic contamination, likely transported by ocean currents and rivers.
Microplastics in fish gut, first records from the Tom River in West Siberia, Russia
AI summary Read the abstract
This preliminary study found an average of 204 microplastic particles per fish in the digestive tracts of 13 dace sampled from the Tom River in West Siberia, Russia — the first such record from this region. Most particles were irregular fragments, with sizes under 0.5mm, suggesting that microplastic contamination has reached remote Siberian river systems.
Evidence for Microplastics Contamination of the Remote Tributary of the Yenisei River, Siberia—The Pilot Study Results
AI summary Read the abstract
Researchers found microplastic concentrations of 1.20 to 4.53 items/m³ in surface water and up to 543 items/kg in bottom sediments of the Nizhnyaya Tunguska River, a remote Yenisei tributary in Siberia, with concentrations likely originating from local human activity and increasing downstream.
