Microplastic Contamination in Water Bodies: Sources, Fate, and Ecological Impacts in Native Rivers
AI summary Read the abstract
Tiny plastic bits are ending up in rivers, even remote ones far from cities, coming from trash breakdown, wastewater, and even air. This review of existing research shows these particles can harm river life by physically injuring them and releasing or carrying harmful chemicals, which matters because these same waterways often feed into our drinking water and food supply. Scientists still need better tools to measure the problem and stronger policies to stop plastic pollution at its source.
Microplastic (MP) contamination is a growing environmental challenge impacting freshwater and native river systems. This review synthesizes current knowledge on MP sources (primary and secondary fragmentation), their entry into rivers (e.g., wastewater, runoff, atmospheric deposition), and their complex fate influenced by hydrodynamics, particle characteristics, biofilms, and biotic interactions. Ecological impacts include physical harm (e.g., gut blockage) and chemical risks from leached additives and adsorbed contaminants, affecting organism health, food webs, and ecosystem functions. Detecting and quantifying MPs, especially in diverse and remote river matrices, faces significant methodological challenges. Even native rivers are susceptible, highlighting MP's pervasive nature. Effective mitigation requires a multi faceted approach: source reduction, improved waste/wastewater management, and ongoing research into long-term impacts, standardized methods, and remediation. Protecting riverine ecosystems, particularly sensitive native rivers, demands integrated management and global cooperation.

Microplastics in Aquatic Ecosystems: A Critical Review of Sources, Transport Mechanisms and Ecotoxicological Risks
AI summary Read the abstract
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 pollution in aquatic environments with special emphasis on riverine systems: Current understanding and way forward
AI summary Read the abstract
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 contamination, an emerging threat to the freshwater environment: a systematic review
AI summary Read the abstract
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.

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.
Microplastics in Indian Freshwater Systems: Current Status and Future Research Needs
AI summary Read the abstract
This review paper pulls together existing research on tiny plastic particles (microplastics) found in India's rivers and lakes, highlighting how widespread they've become in freshwater systems that many people rely on for drinking water and fishing. The authors point out that scientists still don't fully understand how much of these plastics end up in our food and water, or what health risks they might pose—meaning more research is urgently needed to answer these open questions. Since freshwater is a direct pathway for microplastics to enter our bodies, understanding this contamination matters for anyone drinking tap water or eating fish from affected areas.
