Spatiо-Temporal Study of the Ecological State of Water Bodies Located within the Detached Objects of the Urbanized Territory of Ukraine
This paper examines how urbanization affects the ecological health of water bodies over time, finding that various types of human activity degrade water quality. Urban runoff is a major pathway by which microplastics and other pollutants enter aquatic ecosystems.
Analysis of the Influence of Anthropogenic Factors of the Urbanized Territory of Poltava Region (Ukraine) on the State of River Water
This study analyzed anthropogenic factors affecting river water quality in the Poltava region of Ukraine, examining how urban areas influence mineralization and other water parameters. The research provides insight into how human settlement patterns degrade freshwater quality in this region.

This Ukrainian-language study assessed the water quality and ecological status of the Saksahan River in the context of its suitability for drinking water supply and fisheries management, in a region affected by intensive iron ore mining and significant mine water discharge. The research characterized the specific hydrochemical conditions resulting from industrial exploitation of the Kryvbas ore deposits.
Environmental and Spatial Aspects of Pollution of the Territory of Ternopil Region with Microplastic Masses
Researchers assessed microplastic pollution across the Ternopil region of Ukraine, finding that environmental degradation of discarded plastic waste produces widespread invisible microparticle contamination with adverse implications for ecosystem and human health.
Environmental problem of microplastics in Southern Bessarabia
Researchers investigated microplastic pollution in the Southern Bessarabia region of Ukraine, examining drinking water extracted from 40-meter depth wells and finding microplastic contamination linked to inadequate municipal solid waste management practices in Danube Delta communities where waste is buried rather than processed.
Water Quality Analysis and Its Impact on Biodiversity in Freshwater Ecosystems
Researchers measured physicochemical water quality parameters and biological communities at five freshwater sites with varying degrees of anthropogenic disturbance, using correlation analysis, PCA, and cluster analysis to link water quality to aquatic biodiversity. They found strong positive correlations between dissolved oxygen and species richness, and significant negative associations between BOD, nitrate, heavy metals, and biodiversity, concluding that degraded water quality directly compromises freshwater ecosystem function.
Factors of Environmental Safety Reduction on Styr River in the City of Lutsk (Ukraine)
Researchers assessed environmental safety factors affecting the Styr River in Lutsk, Ukraine, documenting microplastic contamination at the microscale alongside other anthropogenic pressures as part of a landscape-level analysis of urban river health.
Analysis of the Sources of Microplastics in the Azov Sea
This study (in Russian) analyzed the sources of microplastics entering the Azov Sea, a shallow inland sea between Russia and Ukraine. Identifying input sources — including rivers, urban runoff, and industrial discharge — is essential for developing effective strategies to reduce microplastic contamination in this important fisheries region.
Evaluation of nitrate pollution sources in surface water across the typical rural-urban interface: a case study of Wen-Rui Tang River, China
Researchers identified the main sources of nitrate pollution in a rural-urban Chinese river, finding that human sewage and agricultural runoff were the primary contributors. While focused on nitrogen pollution, the study illustrates how mixed land use creates complex water quality challenges in rivers that also carry microplastics.
Study of microplastic content in fish in the Neva River and Lake Ladoga
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.
Evaluation of microplastic pollution in the Vilnelė River
Researchers conducted experimental measurements and numerical simulations of microplastic pollution in the Vilnelė River, finding average concentrations between 0.10 and 0.42 particles per litre at measurement points and up to 31.6 particles per litre at release sites, with synthetic polymer microplastics dominating.
First evidence of microplastics in a freshwater river and their relationship to water quality
Researchers measured microplastic concentrations in a freshwater river used for recreational purposes and found a significant relationship between microplastic abundance and water physicochemical quality parameters, along with the presence of three organic compounds, providing evidence that microplastic pollution and water quality are closely linked.
Integrated assessment of the surface source of water supply according to environmental-risk indicators
Researchers assessed surface water quality and environmental health risks in the Dnipro Reservoir watershed using a four-stage risk assessment framework, identifying wastewater discharge, uncontrolled runoff, and bank erosion as major pollution sources. The study quantified health risks from multiple contaminants to support water supply management.
Microplastics in lakes and rivers: an issue of emerging significance to limnology
Researchers found that microplastic concentrations in freshwater lakes and rivers can exceed those of living organisms like zooplankton, with sediment levels matching the most contaminated marine sites, establishing microplastics as a significant issue for limnology.
Investigation of Microplastics Presence in the Dambovita River
Researchers investigated the presence and distribution of microplastics in the Dambovita River, contributing to growing evidence of plastic pollution in freshwater systems across Romania.
Microplastics in Polish Inland Waters: CurrentKnowledge, Methodological Limitations,and Research Needs
Researchers reviewed 33 studies on microplastic contamination in Polish rivers, lakes, and groundwater, finding concentrations ranging from 0 to 280 particles per liter in water and up to 120,000 particles per kilogram in sediments. The review highlights that inconsistent sampling and identification methods make it nearly impossible to compare results across studies, calling for standardized national monitoring.
Microplastics in the Water of Transboundary Lake Khanka and Rivers of Its Basin
Researchers conducted a novel assessment of microplastic concentrations in the surface waters of transboundary Lake Khanka and its tributary rivers, collecting and analysing samples in 2021-2022 to characterise plastic pollution in this cross-border freshwater system.
Disturbances of MPs on nitrogen in surface water: A case study of Chinese water bodies in the past three years
This study investigated whether the presence of microplastics in Chinese rivers and lakes correlates with nitrogen pollution — specifically ammonia nitrogen and total nitrogen levels. Analyzing water quality data collected over three years, the researchers found statistical associations suggesting that microplastics disturb nitrogen cycling in surface waters, potentially by affecting the microbial communities that process nitrogen compounds. Understanding this interaction matters because both microplastics and excess nitrogen are major threats to freshwater ecosystem health.
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.
