ClearImpacts 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 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.
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 effects of microplastics on biota: a review
This review examines the ecological impact of microplastics on organisms across different levels of the food chain, from plankton to fish. Researchers found that microplastic exposure triggers a range of harmful effects including oxidative stress, immune disruption, reproductive problems, and altered feeding behavior. The evidence suggests that microplastics pose a widespread toxicological threat to wildlife, though more research is needed to understand the long-term population-level consequences.
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.
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.
Ecotoxicological and physiological risks of microplastics on fish and their possible mitigation measures
This review summarizes how microplastics affect fish health, including reduced feeding, impaired gill function, weakened immune systems, and reproductive problems. Researchers found that microplastics can transfer through the food chain from smaller organisms to top predators, raising concerns about broader ecosystem impacts. The study also highlights mitigation strategies such as reducing single-use plastics, recycling, and using bioplastics.
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.
A Review of the Sources, Distribution Characteristics and Toxic Effects of Marine Microplastics
This comprehensive review examined the sources, distribution characteristics, and toxic effects of marine microplastics on fish, noting that MPs have been detected in tissues across many marine fish species. The review covered both direct threats from physical damage and chemical toxicity, and indirect physiological and behavioral effects, calling for deeper investigation into long-term impacts.
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.
Effects of Microplastic Exposure on Different Speciesin Ecosystem
This review examines the ecotoxicological effects of microplastic exposure on organisms across aquatic and terrestrial ecosystems, covering bioaccumulation and trophic transfer in fish, mollusks, and other species. The authors emphasize that microplastics originating from industrial processes and plastic waste pose long-term ecosystem-wide threats.
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.
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.
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.
The Challenge of Microplastics in Aquatic Ecosystem: A Review of Current Consensus and Future Trends of the Effect on the Fish
