Occurrence and Impacts of Microplastics in Freshwater Fish
Summary
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.
Plastic production continues to increase as most developed and developing countries continue to adopt the use-and-dispose culture, while some try to implement regulations in the production and recycling of these materials. This high production associated with their durability, unsustainable use, and inappropriate waste management contributes to the introduction and extensive accumulation of plastic debris in natural habitats. Microplastics are of emerging concern, but the amount of research done in freshwater environments is nothing compared to that in marine environments. Following this reality, we seek to investigate the occurrence of these contaminants in freshwater fish and what are the possible impacts to these aquatic species and human beings, since we have a tight relation to this resource.

Microplasts in Freshwater Fish – Problems and Challenges
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.
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.
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.
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.
Global Review and Analysis of the Presence of Microplastics in Fish
This global review and meta-analysis compiled data on microplastic occurrence in fish from studies across dozens of countries, finding microplastics in fish from virtually all sampled regions with higher concentrations in coastal and urban-influenced waters. The analysis identified fibers and fragments as the most common forms, and raised concerns about human dietary exposure through fish consumption.
