Microplastics bioaccumulation in fish: Its potential toxic effects on hematology, immune response, neurotoxicity, oxidative stress, growth, and reproductive dysfunction
This review finds that microplastics accumulate primarily in the guts and gills of fish before spreading to other tissues through the bloodstream, causing a cascade of harmful effects including blood changes, immune suppression, nerve damage, and reproductive problems. The severity of harm depends on the size and dose of particles and how long the fish are exposed, with implications for the safety of fish consumed by humans.

The study also highlights mitigation strategies such as reducing single-use plastics, recycling, and using bioplastics.
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.
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.
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.
Microplastics induce toxic effects in fish: Bioaccumulation, hematological parameters and antioxidant responses
Researchers exposed juvenile fish to polyamide microplastics and found the particles accumulated primarily in the intestine, gills, and liver, causing reduced blood oxygen-carrying capacity, liver stress, and disrupted antioxidant defenses. These findings matter because fish are an important food source for humans, and microplastic accumulation in fish tissues could transfer these contaminants to people through their diet.
Environmental toxicology of microplastic particles on fish: A review
This review summarizes how microplastics harm fish through physical damage, inflammation, oxidative stress, immune suppression, genetic damage, and reproductive disruption. These effects matter for human health because toxic substances accumulate and concentrate as they move up the food chain from fish to the people who eat them.
Ecotoxicological impacts of Microplastic (MP) Pollution in Fish
This review synthesizes evidence on microplastic bioaccumulation and ecotoxicological impacts in fish, examining tissue distribution patterns, immune disruption, reproductive harm, and behavioral effects. The authors conclude that microplastics cause multi-system health effects in fish with implications for aquatic ecosystem stability and food safety.
A review of the neurobehavioural, physiological, and reproductive toxicity of microplastics in fishes
This review summarizes how microplastics cause a range of harmful effects in fish, including behavioral changes, brain and immune system damage, oxidative stress, and reproductive disruption through interference with hormone signaling. These findings are relevant to human health because many of the same biological pathways affected in fish also exist in humans, and people consume fish that have accumulated microplastics.
Toxic effects on bioaccumulation, hematological parameters, oxidative stress, immune responses and neurotoxicity in fish exposed to microplastics: A review
This review summarizes how microplastics affect fish health, covering toxic effects on blood, immune system, nervous system, and the buildup of plastics in fish tissues. Microplastics that accumulate in fish can trigger oxidative damage, weaken immune responses, and impair brain-related enzyme activity. Since fish are a major protein source for humans, understanding how microplastics harm fish health is directly relevant to the safety of our food supply.
Microplastic toxicity in fish: A potential review on sources, impacts, and solution
This review summarizes research on how microplastics affect fish health, covering sources of contamination, physical damage, hormonal disruption, and behavioral changes. Microplastics accumulate in fish tissues and can concentrate up the food chain, with potential toxic effects passing on to humans who eat contaminated seafood. The authors discuss possible solutions including better waste management, biodegradable alternatives, and advanced water treatment.
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.
Ecological Toxicity, Oxidative Stress and Impacts of Microplastics on Fish Gills
This review summarizes research on how microplastic exposure damages fish gills, a critical organ for breathing, waste removal, and maintaining body chemistry. Researchers found that microplastics cause oxidative stress, DNA damage, and structural changes to gill tissue, which can impair blood parameters and overall fish health. The findings highlight that gill damage from microplastics may be a widespread concern for freshwater and marine fish populations.
Meta-analysis of the effects of microplastic on fish: Insights into growth, survival, reproduction, oxidative stress, and gut microbiota diversity
A meta-analysis of 3,757 biological endpoints from 85 studies found that microplastic exposure significantly inhibits fish growth, survival, and reproduction while increasing oxidative damage, but does not significantly alter gut microbiota diversity. The severity of toxic effects depends on microplastic type, size, concentration, exposure pathway, and the fish's life stage.
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.
Water Quality and Fish Health: Interaction with Toxic Substances
This review examines how various toxic substances in water, including microplastics, affect fish health through physiological, behavioral, and biochemical pathways. Researchers summarized evidence that pollutants can accumulate in fish tissues and impair their immune systems, reproduction, and organ function. The study emphasizes that declining water quality from emerging contaminants poses growing risks to aquatic ecosystems and the species that depend on them.
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.
