Risk Assessment of Climate Change Impacts on Urban Discharge Fraction and Eutrophication in Large European River Networks
Researchers assessed how climate change could worsen water quality in European rivers by increasing nutrient pollution from urban areas. While not focused on microplastics, this study highlights the broader environmental pressures on freshwater systems that also carry microplastic contamination.
The contamination of inland waters by microplastic fibres under different anthropogenic pressure: Preliminary study in Central Europe (Poland)
This Polish study measured microfiber contamination in a river and three lakes across central and northeastern Poland, finding significantly higher fiber counts in the river flowing through large cities than in lakes within a protected landscape park. Urban rivers carry substantially higher microplastic fiber loads than relatively undisturbed freshwater bodies, confirming that human activity drives contamination levels.
Screening of Мicroplastic Сontent in Surface Waters of Russian Rivers
Microplastics were detected in surface waters of multiple Russian rivers across different watersheds, with secondary plastic forms indicating fragmentation of larger plastic waste as the dominant source. Sampling covered rivers in the Ural, Siberian, and European Russia regions. The study establishes baseline data for microplastic contamination in understudied Russian freshwater systems.
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.
Biogenic pollution of the Unava River waterbody
Researchers assessed biogenic pollution in the Unava River in Ukraine by measuring nitrogen and phosphorus concentrations across sampling sites, finding that nitrite nitrogen concentrations affect water quality depending on intended use and aquatic ecosystem function, identifying whether nitrogen- or phosphorus-based contamination predominates.
Assessment of Micro-Plastic Contamination in Urban River Systems: A Case Study Using UK Catchment Data
This systematic review examines microplastic contamination in urban rivers across the UK, finding that wastewater treatment plants, stormwater runoff, and industrial discharge are the main sources. The research matters for human health because urban rivers supply drinking water and recreational areas, and microplastic pollution in these waterways increases the risk of human exposure.
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.
Water Quality Evaluation, Spatial Distribution Characteristics, and Source Analysis of Pollutants in Wanquan River, China
This paper is not about microplastics — it assesses water quality in a Chinese river basin, finding that agricultural runoff and domestic sewage are the main pollution sources, without examining plastic contamination.
From headwaters to receiving waters: river dynamics in an increasingly urban world
This paper is not about microplastics; it synthesizes research on river dynamics from headwaters to receiving waters in urban environments, covering hydrological, ecological, and restoration topics.
Rivers under stress: a comprehensive review on pollutant sources, human and ecological impacts, analytical, statistical, and geospatial methods and restoration strategies, for evaluating river water quality in India
This comprehensive review synthesizes evidence from 145 publications on river pollution across India, covering contamination sources, health impacts, and monitoring methods. Researchers found that untreated sewage is the largest contributor to river degradation, while emerging contaminants including microplastics contribute to bioaccumulation, antibiotic resistance, and health issues in communities living near affected waterways.
An Analytical Framework for Determining the Ecological Risks of Wastewater Discharges in River Networks Under Climate Change
Researchers developed an analytical framework to assess ecological risks from wastewater treatment plant discharges into river networks under climate change scenarios, finding that reduced river flows from climate change will amplify ecological risks from effluent contaminants including microplastics.
Microplastics in urban freshwater : a case study in the city of Amsterdam
This study measured microplastic concentrations in urban freshwater in Amsterdam, the Netherlands, finding widespread contamination across the city's canal network. Urban waterways receive microplastics from multiple sources including stormwater runoff, wastewater overflows, and direct littering.
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.
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.
Causes and side effects of changing water quality in Khassa-Chai river in Kirkuk, Iraq
This study assessed water quality changes in the Khassa-Chai River in Kirkuk, Iraq, across dry and wet seasons, finding that the river fails to meet safe drinking water standards largely due to urbanization and inadequate wastewater management. While focused on chemical and microbial water quality rather than microplastics, poor water management enables microplastic contamination in similar urban rivers.
Impact of the long-time armed conflicts on the ecological safety of industrial objects
This article analyzed the environmental consequences of armed conflict on industrial facilities in eastern Ukraine, including contamination of groundwater, surface water, and agricultural land from damaged mines and factories. Long-running conflicts can disable environmental safeguards and create lasting ecological damage. The case study highlights the environmental dimension of armed conflict as an underrecognized public health and ecological crisis.
Analysis of concentrations of biogenic compounds discharged into water bodies with municipal wastewater
