ClearMicroplastics as a contaminant in Indian riverine system: a review
This systematic review examines microplastic contamination across India's river systems, documenting the types, sources, and concentrations of plastic particles found in major waterways. The findings are concerning for human health because these rivers provide drinking water and irrigation for hundreds of millions of people, creating widespread potential exposure to microplastics.
Microplastics in Freshwater Environments – With Special Focus on the Indian Scenario
This review examines microplastic pollution in freshwater environments globally with a focus on the Indian context, finding that despite India being one of the world's largest contributors to marine plastic pollution, freshwater microplastic research in India remains almost entirely absent, and calling for systematic river catchment monitoring to quantify land-to-ocean plastic fluxes.
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.
The first report on the source-to-sink characterization of microplastic pollution from a riverine environment in tropical India
This first source-to-sink study of microplastic pollution in a tropical Indian river system tracked microplastics from urban sources through the river to estuarine and coastal deposition zones, characterizing polymer types and morphologies at each stage.
The processes and transport fluxes of land-based macroplastics and microplastics entering the ocean via rivers
This review traces the full journey of plastic waste from land to ocean via rivers, covering how plastics enter waterways and the methods scientists use to estimate how much reaches the sea. About 80% of marine plastic pollution comes from land-based sources, and better monitoring and modeling are needed to improve estimates. Understanding these transport pathways is essential for reducing the microplastic contamination that ultimately enters the seafood supply and affects human health.
Comprehensive Review on Microplastic Pollution in Inland Waters of India
This comprehensive review examines microplastic pollution in India's inland freshwater systems, including major rivers like the Ganga, Yamuna, and Brahmaputra. The study highlights that rapid industrialization, urbanization, and poor waste management have led to significant contamination from diverse sources including industrial effluents, untreated sewage, and agricultural runoff, with potential consequences for aquatic organisms and human health through bioaccumulation in food chains.
Microplastics in Rivers from Developing Countries
This review examines microplastic contamination of rivers in developing countries, identifying the major sources—including inadequate waste management and open burning—and reviewing evidence that these rivers serve as major conduits delivering plastic pollution to the ocean.
From pollution to solutions: Insights into the sources, transport and management of plastic debris in pristine and urban rivers
This review examines how river systems receive and transport plastic debris -- including both macroplastics and microplastics -- from land sources to the ocean, synthesizing evidence on pollution sources, fate, and management strategies across pristine and urban rivers.
River plastic transport and storage budget.
This global synthesis estimated the plastic transport and storage budget for rivers by measuring plastic in the water surface, water column, riverbanks, and floodplains — finding that far more plastic is stored within rivers than is transported to the ocean. The study challenges the assumption that rivers are primarily conduits and highlights them as major long-term plastic reservoirs.
A Comprehensive Review of MP Pollution in Global Rivers: Distribution Patterns and Fluvial Transport Dynamics
A global review of microplastic pollution in river sediments found the highest concentrations in Africa and Asia, with wastewater treatment plants, industrial discharges, and urban runoff as the primary sources, and rivers transporting an estimated 70–80% of land-based plastic waste to the oceans. This synthesis underscores that rivers are critical intervention points for reducing the flow of microplastics into marine ecosystems.
A Critical Review on the Characterization and Distribution of Microplastic Contaminants in Indian Water Environments: Pathways and Related Hazards
This systematic review examines microplastic contamination in India's freshwater environments, including rivers and lakes. While marine ecosystems have gotten the most attention, freshwater sources — which supply drinking water — are also heavily contaminated. The findings highlight how inadequate waste management and recycling infrastructure allow microplastics to spread through the water systems that communities depend on.
Baseline Study on Microplastics in Indian Rivers under Different Anthropogenic Influences
Researchers collected microplastic samples from Indian rivers under different levels of anthropogenic influence and found MPs in all sites, with concentrations correlating with population density and industrial activity, providing one of the first systematic field datasets for major Indian river systems.
A catchment‐scale perspective of plastic pollution
This review framed plastic pollution from a catchment-scale perspective, synthesizing evidence on plastic sources, transport dynamics, and effects across terrestrial, freshwater, and marine environments within river drainage basins. The authors find that rivers are hotspots for plastic pollution and pivotal conduits to the ocean, and call for integrated catchment-level management rather than environment-by-environment approaches.
Sources and Impact of Microplastic Pollution in Indian Aquatic Ecosystem: A Review
This review examines sources and impacts of microplastic pollution across Indian aquatic ecosystems, documenting widespread contamination in marine and freshwater environments and discussing risks to living organisms given projections that ocean plastic will outweigh fish by 2050.
Microplastics in Freshwater Ecosystems in India: A Comprehensive Review
This review examines the occurrence, sources, and ecological risks of microplastics across freshwater ecosystems in India, synthesizing current literature on contamination levels in rivers, lakes, and other inland water bodies.
Rivers as Plastic Reservoirs
Researchers introduce the concept of river systems as plastic reservoirs, arguing that most land-based plastic waste never reaches the ocean. They found that rivers retain the vast majority of plastics within their terrestrial and aquatic compartments, where they can persist for years to centuries. The study reframes rivers not just as transport pathways for marine plastic pollution, but as significant long-term storage environments for plastic waste.
Microplastics pollution in inland aquatic ecosystems of India with a global perspective on sources, composition, and spatial distribution
Researchers reviewed microplastic contamination in India's rivers, lakes, and wetlands, finding widespread pollution across water, sediment, and wildlife, with concentrations peaking during monsoon season due to runoff. The review highlights a critical gap: most studies don't account for how water flow and seasonal variation affect where microplastics go, making it hard to gauge the true health risk to people and ecosystems.
Microplastics in Indian aquatic systems and its effects on plants, aquatic organisms and humans, and its methods of remediation
This review summarizes microplastic pollution across India's rivers, coasts, and estuaries, finding contamination widespread in both water and sediment. The highest concentrations were found in estuaries and the Hooghly River, with most research focused on southern India's coastal areas. The study highlights that microplastics in Indian waterways pose health risks to the large populations that depend on these water sources for drinking, fishing, and irrigation.
River plastic transport and storage budget
This study provides the first systematic budget of how plastic moves through rivers and where it gets stored, finding that riverbanks and floodplains trap far more plastic than the surface water layer that is typically monitored. Rivers act not just as pipelines delivering plastic to the ocean but as large reservoirs that accumulate and slowly release plastic over time. Understanding this full storage picture is essential for estimating how much microplastic will eventually reach the ocean and for designing effective river cleanup strategies.
Impact Pollution Microplastics in Rivers in Indonesia
This Indonesian review examines the problem of microplastic pollution in rivers across Indonesia, describing the sources, distribution, and environmental impacts of plastic debris in river ecosystems. Plastic waste from poorly managed urban and rural areas enters rivers and fragments into microplastics that accumulate throughout the water column and sediments. The findings underscore the urgent need for improved waste management infrastructure across Indonesian communities.
Rivers as Conduits: A Comprehensive Model of Microplastic Fate and Transport
This study developed a comprehensive model of microplastic fate and transport in rivers, integrating processes of erosion, resuspension, sedimentation, and burial to simulate how microplastics move through river networks toward the ocean.
Microplastic Pathways: Investigating Vertical and Horizontal Movement from Riverine Environments to Oceans
Researchers investigated the vertical and horizontal movement of microplastics in riverine systems en route to the ocean, examining how physical MP characteristics and hydrodynamic conditions govern whether particles settle near riverbeds or float at the surface, and how both gravity-driven and flow-driven transport contribute to their ultimate fate.
