ClearSpatiо-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.
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.
Analysis of the Influence of Anthropogenic Factors of the Urbanized Territory of Poltava Region (Ukraine) on the State of River Water

Researchers surveyed microplastic distribution in urban river environments and identified key drivers of accumulation hotspots, finding that land use, hydrology, and infrastructure factors concentrated microplastics at predictable locations that could inform targeted management interventions.
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.
Microplastic pollution differences in freshwater river according to stream order: Insights from spatial distribution, annual load, and ecological assessment
Researchers compared microplastic pollution levels in a freshwater river across different land-use zones, finding higher concentrations near urban and agricultural areas than in forested regions. Fiber-type microplastics were predominant across all sampling locations.
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.
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.
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.
Microplastic analysis in urban areas and their impact on quality of life
Researchers assessed microplastic contamination in urban water environments and evaluated its impact on community quality of life, arguing that a critical gap in standardized analytical methods is limiting progress in both research and environmental management of microplastic pollution.
Assessment of microplastic contamination in the Loire River (France) throughout analysis of different biotic and abiotic freshwater matrices
This study assessed microplastic contamination in the Loire River, France, across multiple environmental compartments, investigating how anthropogenic activities in a medium-sized city affect microplastic levels and transport in a major European freshwater system.
Microplastic analysis in urban areas and their impact on quality of life
Researchers reviewed the growing threat of microplastic pollution to biodiversity and human health, focusing on freshwater systems as a key exposure pathway. The study emphasizes the need for standardized identification methods for microplastics in freshwater environments.
Anthropogenic Litter in Urban Freshwater Ecosystems: Distribution and Microbial Interactions
Researchers quantified anthropogenic litter in urban rivers and streams and found that microplastics dominated by mass and particle count compared to macroplastic items. The study highlights urban freshwater systems as major conduits for plastic pollution moving toward marine environments and documents distinct microbial communities on plastic surfaces.
Characteristics, Contamination Levels, and Ecosystem Risk Assessment of Microplastics in Surface Water of a Highly Urbanized River from a Developing Country
Researchers characterized microplastic contamination in an urban river near a megacity in a developing country, finding concentrations of 350 to 660 particles per cubic meter of water. Polyethylene and polypropylene from household and municipal waste were the most common types, and a risk assessment found concerning contamination levels at several sampling sites. The study highlights how rivers in developing nations can serve as major pathways for microplastics to reach the ocean and enter the food chain.
Microplastic pollution in sophisticated urban river systems: Combined influence of land-use types and physicochemical characteristics
This study assessed microplastic pollution across an urban river network in China, finding that land-use type and water physicochemical properties jointly influence microplastic distribution, with industrial and residential areas contributing highest loads.
Analysis of the Status of Surface Waters in the Sącz Agglomeration Based on Physicochemical Parameter Studies
Not relevant to microplastics — this paper reports physicochemical water quality measurements (heavy metals, suspended solids, pesticides) in rivers near the Sącz agglomeration in Poland, with no focus on plastic pollution.
Microplastics Occurrence in Two Mountainous Rivers in the Lowland Area—A Case Study of the Central Pomeranian Region, Poland
Researchers conducted the first microplastic survey of two mountainous rivers flowing through landscape parks and urbanized zones in northern Poland, analyzing morphological types, sizes, and seasonal variation in microplastic occurrence. The study characterized microplastic contamination in rivers that serve as habitat for sea trout and salmon, connecting urban pollution to protected aquatic ecosystems.
