The Role of Rivers in Microplastics Spread and Pollution
AI summary Read the abstract
Rivers function as the primary transport corridors for microplastics from land-based sources to oceans, carrying particles downstream through complex hydrological and biological interactions. Targeting river pollution hotspots with intervention measures is one of the most impactful strategies available for reducing the total global flux of microplastics into marine environments.
Microplastics pollution in water has been observed since the early 1970s and continues to develop. The microplastics transport route has been studied in more detail by researchers from various regions. One of the essential pathways for microplastics pollution is...

Microplastics Pollution in Rivers
AI summary Read the abstract
Rivers serve as both reservoirs and transport highways for microplastic pollution, carrying particles from inland sources to lakes and marine environments while exposing freshwater organisms to contamination along the way. River-borne microplastics directly threaten drinking water quality and aquatic biodiversity worldwide.
Trailing the flow: source, fate and sink of microplastics in global rivers
AI summary Read the abstract
This review synthesized global research on microplastic pollution in rivers, covering sources, entry routes, and the key processes governing transport and transformation—including weathering, aggregation, sinking, and resuspension—along with ecotoxicological and socioeconomic impacts. Because rivers are the primary conduit transferring land-based microplastics to the ocean, understanding riverine dynamics is essential for designing effective interception strategies before contamination reaches marine food webs and human seafood supplies.
Impact and Fate of Microplastics in the Riverine Ecosystem
AI summary Read the abstract
Researchers reviewed the fate, transport, and ecological impacts of microplastics in riverine ecosystems, finding that rivers serve as major conduits for microplastic transfer from terrestrial sources to oceans and that riverine biota face significant exposure-related health risks.
Microplastics pollution in the rivers, its source, and impact on aquatic life: a review
AI summary Read the abstract
Researchers reviewed global evidence of microplastic contamination in rivers and lakes, finding that plastic particles serve as carriers for toxic chemicals, harm aquatic life through ingestion and entanglement, and enter human food and water supplies, while also exploring plant-based plastic alternatives that could reduce future pollution.
Beyond our oceans: Microplastics pollute rivers and lakes too
AI summary Read the abstract
Researchers and journalists highlighted that microplastic pollution extends well beyond the ocean, contaminating rivers, lakes, and terrestrial ecosystems — environments that supply much of the world's drinking water and food. This broader distribution suggests human exposure to microplastics may be more widespread than previously recognized.
