ClearAssessing the Effects of Microplastics on Freshwater Fish
This review examines the growing body of research on how microplastics affect freshwater fish, documenting evidence of ingestion, tissue damage, immune system impairment, and gastrointestinal obstruction across multiple species. Researchers highlight that microplastics from personal care products and degraded plastic goods are accumulating in freshwater ecosystems at concerning rates. The study warns that combined with existing threats like overfishing and habitat loss, microplastic pollution could accelerate population declines in vulnerable fish species.
Impacts of microplastic accumulation in aquatic environment: Physiological, eco-toxicological, immunological, and neurotoxic effects
This review summarizes how microplastics build up in fish and other aquatic life, causing damage to their immune systems, nervous systems, and overall health. When fish eat microplastics, the particles move up the food chain and can eventually reach humans through seafood consumption. The authors also discuss strategies for removing microplastics from water and reducing plastic pollution.
Impacts of Microplastics as Contaminants in Freshwater Ecosystems and Human Food Chain
This review examines the impacts of microplastics on freshwater ecosystems and human food chains, tracing how plastic particles enter rivers and lakes, accumulate in fish and invertebrates, and transfer to humans through consumption of contaminated freshwater species.
Effects of microplastics in freshwater fishes health and the implications for human health
This review examines how microplastics affect the health of freshwater fish, which are a major protein source for billions of people. Fish ingest microplastics that accumulate in their guts, gills, and tissues, leading to inflammation, oxidative stress, and disrupted growth. Since microplastics in fish tissue can transfer to humans through the food chain, this is relevant to both ecosystem and human health.
Exploring the ecotoxicological impacts of microplastics on freshwater fish: A critical review
This review examines how microplastics affect freshwater fish, which often mistake the tiny particles for food. Once ingested, microplastics do not stay in the gut -- they enter the bloodstream and spread to the gills, liver, brain, heart, and reproductive organs, causing hormonal, immune, neurological, and reproductive problems. Because microplastics build up in the food chain, the contamination of fish has broader implications for other animals and for people who eat freshwater fish.
Toxic effects of polyethylene-microplastics on freshwater fish species: Implications for human health
This study reviews the toxic effects of polyethylene microplastics on freshwater fish species and the implications for human health, drawing on a body of existing literature on plastic pollution in aquatic ecosystems. The work synthesizes evidence of microplastic ingestion, bioaccumulation, and physiological effects in freshwater fish with relevance to human dietary exposure.

This review examines microplastic contamination of freshwater fish, covering ingestion evidence from over 150 species, the mechanisms of accumulation in gastrointestinal and other tissues, potential health impacts, and challenges in standardizing quantification methodologies.
The Impact of Microplastics on Fish Poses a Threat to Human Health
This review summarizes how microplastics ingested by fish accumulate through the food chain, posing a direct threat to human health via consumption of contaminated seafood.
Occurrence and Impacts of Microplastics in Freshwater Fish
This review summarizes research on microplastic occurrence in freshwater fish across multiple regions, examining ingestion rates, polymer types, and potential health effects. The authors highlight that freshwater fish are widely exposed to microplastics and call for more standardized monitoring to assess risks to fish and to people who eat them.
Microplastics in Aquatic Environments and Their Toxicological Implications for Fish
This review summarizes research on microplastic occurrence in freshwater and marine environments and the toxicological risks they pose to fish, examining both direct physical effects and the role of plastics as vectors for chemical pollutants. The authors highlight that freshwater fish are particularly vulnerable given the high loads of microplastics in rivers receiving wastewater.
The Challenge of Microplastics in Aquatic Ecosystem: A Review of Current Consensus and Future Trends of the Effect on the Fish
This review synthesizes research on how microplastics affect aquatic ecosystems, covering ingestion by marine animals, trophic transfer up the food chain, and the chemicals that microplastics carry. The findings highlight that microplastic contamination is now widespread enough to threaten marine biodiversity and food security for populations that rely on seafood.
Microplastics in freshwater fishes: Occurrence, impacts and future perspectives
This review synthesizes current knowledge about microplastic contamination in freshwater fish, which serve as important indicators of plastic pollution in rivers and lakes. Researchers found that microplastic ingestion patterns in fish are related to body size, feeding habits, and local urbanization levels, with controlled studies showing various effects on fish physiology and behavior. While fish can typically expel most microplastics quickly, certain particle shapes and sizes may remain in the body or cross into other organs through the intestinal wall.
Bioavailability and toxicity of microplastics to fish species: A review
This review summarizes current knowledge about microplastic ingestion and its toxic effects in fish species worldwide. Researchers found that microplastics have been detected in fish from nearly all types of aquatic habitats, and both field and laboratory studies confirm fish are highly susceptible to ingesting these particles. The study notes that microplastics alone or combined with other pollutants can cause various health problems in fish, raising concerns about implications for human seafood consumption.
Assessing and Managing Microplastic Risks in Freshwater Fisheries: Exposure Pathways and Toxicological Evidence
This review assessed microplastic exposure pathways and toxicological risks for freshwater fish in rivers, lakes, reservoirs, and aquaculture ponds, covering ingestion, trophic transfer, and chemical co-contaminant effects. The authors concluded that freshwater fish face substantial microplastic risk and outlined monitoring and risk management strategies for fisheries managers.
Microplastics in Freshwater Ecosystems: Sources, Transport and Ecotoxicological Impacts on Aquatic Life and Human Health
This review summarizes how microplastics enter freshwater ecosystems from sources like industrial runoff, urban waste, and agriculture, and how they accumulate in sediments where aquatic organisms ingest them. Researchers found that microplastics reduce feeding efficiency, inhibit growth, and harm reproduction in freshwater species, while also acting as carriers for toxic chemicals that build up through the food chain. The study highlights the need for better waste management and further research to understand the full scope of risks to both aquatic life and human health.
