ClearMicroplastic pollution in aquatic environments with special emphasis on riverine systems: Current understanding and way forward
This review examines microplastic pollution in freshwater riverine systems, which serve as a critical link between terrestrial and marine environments. Researchers found that rivers are significantly contaminated with microplastics of varying sizes and morphologies, and that these particles can exhibit variable toxicity to aquatic organisms, highlighting the need for more research on freshwater microplastic impacts.
Microplastic pollution in riverine ecosystems: threats posed on macroinvertebrates
This review examined microplastic abundance, distribution, and impacts on macroinvertebrates across riverine ecosystems globally, finding that ingestion of microplastics can physically harm and inhibit growth, reproduction, and feeding in riverine invertebrates, with fibres and fragments being the most common forms.
Microplastics in Aquatic Ecosystems: A Critical Review of Sources, Transport Mechanisms and Ecotoxicological Risks
This review provides a broad overview of microplastic pollution in rivers, oceans, and other aquatic environments, covering where these particles come from, how they move through water systems, and the harm they can cause. Evidence indicates that microplastics accumulate toxins and disrupt growth, feeding, and reproduction in aquatic species, with potential consequences for human health through seafood and drinking water. The authors stress the need for better global monitoring, stronger waste management systems, and development of eco-friendly plastic alternatives.

Microplastic contamination, an emerging threat to the freshwater environment: a systematic review
Researchers systematically reviewed the spread of microplastics in freshwater ecosystems — rivers, lakes, and streams — documenting their sources, how they move through water, the damage they cause to aquatic organisms, and the methods used to detect them. Their review serves as a baseline reference for future research and calls for improved waste management to protect freshwater environments from ongoing microplastic contamination.
Microplastics in the sediments of small-scale Japanese rivers: Abundance and distribution, characterization, sources-to-sink, and ecological risks
Researchers characterized microplastic pollution in sediments of four small-scale Japanese rivers, finding widespread contamination and identifying polymer types and potential sources, highlighting that even small river systems serve as microplastic transport pathways.
Plastic debris in rivers
This review synthesizes current knowledge on plastic debris in rivers, covering sources, transport mechanisms, ecological impacts, and the role of rivers in delivering plastic to the oceans. The authors highlight key knowledge gaps and emphasize that riverine ecosystems are directly harmed by plastic pollution, not merely transit corridors.
Microplastics in aquatic environments: a growing, unresolved concern
This review examines the origins, behavior, fate, and ecological effects of microplastics in aquatic environments. It synthesizes current research showing that microplastics are ubiquitous in rivers, lakes, and oceans, where they harm organisms and accumulate in food webs, raising ongoing concerns about ecosystem health and food safety.
Micro Plastic Pollution in Freshwater Ecosystems: Sources, Fate and Effects
This review addresses microplastic pollution in freshwater ecosystems, examining sources including synthetic textile washing microfibers and cosmetic microbeads, and the secondary fragmentation of larger plastic debris. The authors assess the fate of particles in rivers and lakes, their effects on aquatic organisms, and the adequacy of current management approaches.

Microplásticos en ecosistemas acuáticos: una revisión sobre su impacto y gestión
This literature review analyzes the ecological impact of microplastic pollution in aquatic ecosystems and available management strategies. Researchers found that microplastics affect aquatic organisms through ingestion and bioaccumulation, altering physiological functions and acting as vectors for toxic pollutants and pathogens. While filtration technologies, bioremediation, and regulatory measures have been developed, their effectiveness remains limited and a comprehensive approach combining prevention, mitigation, and stricter policies is needed.
A critical review of environmental factors influencing the transport dynamics of microplastics in riverine systems: implications for ecological studies
This review examines how environmental factors like river flow, channel shape, vegetation, and sediment influence where microplastics accumulate and how they travel through river systems. The authors found that microplastic transport is far more complex than previously assumed, with particles behaving differently based on their size, shape, and density. Understanding these dynamics is essential for predicting where microplastics end up and designing effective cleanup strategies.
