ClearMicroplastic 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 as an Emerging Threat to the Freshwater Fishes: a Review
This review examines microplastics as an emerging threat to freshwater fishes, covering their sources from cosmetics and plastic debris fragmentation, routes of entry including wastewater treatment plants, and documented toxic effects on fish physiology and behavior.
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.
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.
Microplastics in Fish: A Comprehensive Review
This review synthesizes research on microplastics in fish, covering contamination sources, detection methods, and impacts on wild and farmed populations globally — and examining how plastic particles in fish tissues may transfer to humans through seafood consumption.
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.
Microplastics exposures of fish: internalization and effects on behavior and growth
This study examined how microplastics affect fish behavior and growth, finding that fish can ingest them but particles pass through the gut relatively quickly with limited effects at tested concentrations. The research highlights challenges in detecting microplastics in aquatic organisms and suggests risk depends heavily on exposure level and particle type.
Effects Of Microplastics On Fish Physiology
