Occurrence and Detection Problems of Micro- and Nanoplastics in the Water Environment of Russia
This review analyzes micro- and nanoplastic contamination in natural waters across Russia, mapping occurrence in rivers, lakes, groundwater, and Arctic regions, and evaluating current detection challenges and methodological limitations for characterizing plastic particles smaller than 5 mm and 100 nm respectively in freshwater and marine environments.
Microplastics Pollution in Water is a Threat for Human Health and the Environment (literature Review)
This Russian literature review synthesizes evidence that microplastics are widespread in water bodies and drinking water, threatening human health through physical irritation, toxic chemical leaching, and microbial attachment. It notes that microplastics have been documented in aquatic organisms — including fish in Russian rivers — and that contaminated seafood is a key pathway for human exposure. The paper identifies critical gaps: there are no standardized sampling methods or regulatory limits for microplastics in drinking water in Russia.
Micro- and Nanoplastics pollution in the aquatic environments in Russia and detection problems
This Russian review examines micro- and nanoplastic pollution in aquatic environments in Russia and discusses the challenges of detecting these particles accurately. The authors highlight gaps in monitoring coverage and call for standardized detection methods to better understand the extent of plastic contamination in Russian freshwater and marine systems.
Microplastics in Surface Waters of the Russian Arctic Seas: Distribution, Concentration, Identification, and Eco-Risks for Fish
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.
Microplastic Distribution Patterns and Water Quality in the Water Area of the Tsimlyanskoye Reservoir in the Modern Period
Researchers investigated microplastic distribution patterns and water quality in Tsimlyanskoye Reservoir in Russia, characterizing spatial variation in particle abundance and composition across the reservoir's water area in the current period.
Microplastics in freshwater ecosystems: sources, research methods and environmental consequences. Experience of russian researchers and prospects for pollution control in khanty-mansiysk autonomous okrug – yugra
This review analyzes Russian-language and international research on microplastic pollution in freshwater bodies across Russia, focusing on sources including wastewater, urban runoff, and plastic waste decomposition. The authors identify gaps in monitoring coverage for Khanty-Mansiysk Autonomous Okrug and similar remote regions and recommend standardized sampling and analysis protocols.
Microplastic contamination of the setun river
This study documented microplastic contamination in the Setun River in Moscow, Russia, characterizing the types, shapes, and abundance of particles present. Urban rivers like the Setun act as conduits carrying plastic pollution from cities into larger waterways and ultimately to oceans, making their contamination levels important reference points for understanding plastic transport.

Microplastic Pollution in the Surface Waters from Plain and Mountainous Lakes in Siberia, Russia
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.
Occurrence, potential sources, and ecological risk assessment of microplastics in the inland river basins in Northern China
Researchers surveyed microplastic pollution in a typical urban river system in Northern China, examining both surface water and sediment samples. They found that river sediments contained dramatically more microplastics than surface water, acting as a sink for this pollution, with polypropylene and polyethylene being the most common types. The study suggests that small fiber and fragment-shaped particles under 0.5 mm dominate these environments, likely originating from everyday plastic products and wastewater discharge.

Assessment of the sources and inflow processes of microplastics in the river environments of Japan
Researchers mapped microplastic concentrations across 29 Japanese rivers and found plastic particles present at 31 of 36 sampling sites. The concentrations were strongly linked to urbanization and population density, confirming that human activities in river basins are a major driver of freshwater microplastic pollution. The findings demonstrate that significant plastic fragmentation occurs before debris reaches the ocean, making rivers an important area for pollution monitoring.
