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 Freshwater Systems: A Review on Its Accumulation and Effects on Fishes
This review covers the accumulation and effects of microplastics in freshwater fish, including how fish ingest them through feeding and the physical and chemical harm they can cause. Since many freshwater fish species are consumed by humans, the findings are relevant to food safety.
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.
Threats of Microplastic Pollution on Fishes and its Implications on Human Health (Review Article)
This review summarizes research from 2010 to 2023 on microplastic contamination in fish and its potential implications for human health. Researchers found that microplastics are ingested by fish across diverse aquatic environments, with particles accumulating in the gastrointestinal tract and other tissues. The study highlights concerns that microplastic-contaminated seafood may represent a pathway for human exposure to both the plastic particles and associated chemical pollutants.
Assessing 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.
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.
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.
Microplastics in Fish and Shellfish – A Threat to Seafood Safety?
This review evaluated the current knowledge on microplastic contamination in fish and shellfish in relation to seafood safety. Researchers found that while microplastics are commonly detected in the gastrointestinal tracts of fish (which are typically not consumed), bivalves and small fish eaten whole may present a more direct route of human exposure, though the overall health risk from microplastics in seafood remains uncertain.
Plastic Particle Ingestion by Wild Freshwater Fish: A Critical Review
This critical review synthesized data from studies of plastic particle ingestion by wild freshwater fish globally, examining methodological differences and drawing conclusions about the scale and consistency of the problem. The review found ingestion to be widespread across species and geographies but highlighted significant methodological inconsistencies that complicate cross-study comparisons.
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.
Exposure pathway derived accumulation of microplastics in freshwater fish: A critical review
This systematic review of 78 field and laboratory studies synthesized how microplastics accumulate in different freshwater fish tissues depending on exposure pathway, finding that gill-filtered and orally ingested particles follow distinct tissue distribution patterns.
Microplastics in Fish and Fishery Products and Risks for Human Health: A Review
This review summarizes existing research on microplastic contamination in fish and seafood products and the associated human health risks. Microplastics found in fish can carry harmful chemicals and pathogens, and once eaten by humans, they may cause oxidative stress and move from the gut to other tissues. The review highlights seafood as a major dietary source of microplastic exposure and calls for better monitoring and risk assessment.
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.
Microplastic Distribution Patterns in Fish and Implications for Safe Consumption
Researchers examined over 1,000 fish from 37 species and found microplastics in the gills and guts of about 36-40% of fish, but none in muscle tissue. Fish from shallower waters and smaller fish had more microplastics. The study recommends that people eat only the muscle portion of fish and choose larger fish from deeper waters to reduce their microplastic intake, estimating that global per capita exposure from fish is about 56,000 particles per year.
Microplastics in Fish and Seafood Species
This chapter reviews microplastic contamination in fish and seafood species, including how plastics enter seafood through wild capture and aquaculture pathways. Because seafood is widely consumed globally, microplastics in fish and shellfish represent a direct route of human dietary exposure.
Sampling, isolating and identifying microplastics ingested by fish and invertebrates
This study reviewed sampling and identification methods for microplastics ingested by fish and invertebrates, evaluating each approach for accuracy, reproducibility, and applicability to different species and sample types.
Microplastic contamination in wild freshwater fish: Global trends, challenges and perspectives
This global review analyzed 144 studies on microplastic contamination in wild freshwater fish across 45 countries and found that 450 fish species were contaminated, including 35 species on the conservation Red List. Microplastics were most commonly found in the gastrointestinal tract, with fibers and fragments being the dominant shapes. The evidence indicates that freshwater fish worldwide are widely exposed to microplastic pollution, with potential implications for both aquatic ecosystems and human seafood consumption.
Systematic Review of Microplastic Characterization Methods and Associated Toxicological Outcomes in Fish
This systematic review evaluated methods used to identify microplastics and their health effects in fish. The findings showed that microplastic exposure causes liver and gill damage, behavioral changes, and oxidative stress in fish, which matters for human health because contaminated fish is a common part of our diet.
