ClearEffect of microplastics pollution in riverine ecosystem: A review
This review covers microplastic contamination in riverine ecosystems, discussing the diverse forms of microplastics -- including threads, fragments, films, and pellets -- their ingestion by aquatic organisms, long-distance transport, and accumulation in sediments.
Microplastic 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 accumulation in benthic macroinvertebrates is widespread, regardless of the river ecological status
A broad survey of freshwater benthic macroinvertebrates across multiple rivers found that microplastic accumulation was widespread regardless of local urban development levels, suggesting that factors beyond proximity to urban areas—such as river hydrology and upstream sources—drive MP exposure in freshwater invertebrates.
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.
Riverine microplastics and their interaction with freshwater fish
This paper reviews how microplastics enter river systems, how they move through waterways, and the risks they pose to freshwater fish. Researchers found that fish ingest microplastics that can accumulate in organs and carry toxic chemicals absorbed from the water. The review highlights that river fish, an important food source for many communities, face growing exposure to microplastics from urban runoff, wastewater, and agricultural sources.
The ecotoxicological impact of microplastics on freshwater invertebrates
This review summarizes the ecotoxicological effects of microplastics on freshwater invertebrates, finding evidence of harm including reduced feeding, growth, and reproduction across multiple species. Because invertebrates are key links in food webs, these effects could have broader consequences for freshwater ecosystems.
Microplastic loads within riverine fishes and macroinvertebrates are not predictable from ecological or morphological characteristics
Researchers measured microplastic loads in riverine fish and macroinvertebrates and found that particle counts were not reliably predicted by species ecology or morphology, suggesting that individual variation and local environmental factors play a larger role in microplastic ingestion than feeding guild or habitat alone.
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.
The Harmful Effects of Microplastic Pollution on Aquatic Organisms
This review summarized evidence on the harmful effects of microplastic pollution on aquatic organisms in both marine and freshwater environments, covering ingestion, entanglement, and chemical toxicity pathways. The paper highlighted how the lightweight, durable, and widespread nature of plastics makes them a pervasive threat to aquatic biodiversity.
Microplastics in freshwater ecosystems : effects and drivers
This thesis assessed how microplastic exposure affects freshwater microorganisms, macroinvertebrates, and other organisms in freshwater ecosystems, finding that microplastics are a pervasive contaminant of freshwater environments with unclear but potentially significant ecological impacts.
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.
The Invisible Threat: A Review of Microplastics in Freshwater Systems, Including Their Presence in Water, Sediment, and Aquatic Insects
This review examines the sources, spatial distributions, and ecological effects of microplastics in freshwater systems — including water, sediments, and aquatic insects — synthesizing evidence on their pervasive contamination and biological impacts across freshwater environments globally.
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.
Occurrence and characterization of microplastic content in the digestive system of riverine fishes
Researchers found microplastics in 93.8% of riverine fish examined, with polystyrene, polyethylene, and nylon being the most common polymer types concentrated near urban and industrial areas, and small particles (0.025-1 mm) predominating across species.
