Bioaccumulation and Degree of Toxicity of Microplastics in Fish Fauna
Summary
This study (in Spanish) reviews and investigates the bioaccumulation of microplastics in fish fauna and the toxicological consequences, noting that marine microplastic contamination now spans all ocean zones including Antarctica. When plastics fragment in seawater they acquire the ability to adsorb and concentrate chemical pollutants, which then enter food chains and ultimately affect human health. The findings reinforce that microplastics in fish represent both an ecological and a food-safety concern.
La contaminación plástica es omnipresente siendo reportada desde residuos plásticos grandes que flotan en la superficie hasta microplásticos (<5 mm) degradados en las columnas de agua en todos los mares y zonas costeras del planeta (Eriksen et al., 2014), incluyendo la Antártida (Waller et al., 2017). Se ha convertido en una amenaza eminente no solo para todos los ambientes naturales y la vida marina (Cressey, 2016); sino que también por efectos de bioacumulación a través de las cadenas tróficas (Haward, 2018), en última instancia afecta de manera directa la salud humana (Alfaro-Núñez, Alonzo, 2019). Investigaciones recientes sugieren que cuando los compuestos plásticos se encuentran en el océano, presentan propiedades para absorber o liberar contaminantes presentes en el agua (Zarfl et al., 2011). En el momento que este material se fragmenta por la interacción de procesos físicos, químicos y biológicos (Christoph et al., 2016), genera en parte microplásticos, considerados como las partículas menores a cinco milímetros (Lusher et al., 2017; Barrows et al., 2018; Rochman, 2018). Estas micropartículas pueden introducir los contaminantes asociados a las cadenas alimenticias (Sussarellu et al., 2016; Hernández et al., 2018), o incluso circular u obstruir los tractos digestivos de copépodos (Cole et al., 2015), otros invertebrados (Mishra et al., 2019) y vertebrados marinos (Van Franeker y Law, 2015), afectando a esta biodiversidad acuática (Barraza Sandoval et al., 2021). Mediante esta investigación se busca describir el grado de toxicidad producido por la bioacumulación de microplásticos en la fauna íctica de aguas marinas, a través de la revisión de diferentes investigaciones realizadas.

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.
Addressing the current fettle of bioaccumulation of microplastics on the subsequent perspective of the aquatic ecosystem and health implications of commercial species: a review
This review examined evidence for microplastic bioaccumulation in aquatic animals globally, discussing risks to aquatic health, ecosystem function, and the blue economy from widespread plastic particle uptake. The review found bioaccumulation documented across multiple taxa and highlighted food safety implications for humans consuming aquatic species.
Toxic effects of polyethylene-microplastics on freshwater fish species: Implications for human health
This study reviews the toxic effects of polyethylene microplastics on freshwater fish species and the implications for human health, drawing on a body of existing literature on plastic pollution in aquatic ecosystems. The work synthesizes evidence of microplastic ingestion, bioaccumulation, and physiological effects in freshwater fish with relevance to human dietary exposure.
The impact of nano/micro-plastics toxicity on seafood quality and human health: facts and gaps
This review examines the impact of nano- and microplastic contamination on seafood quality and human health. Researchers note that while microplastic absorption in fish is generally considered low, bioavailability depends on the physical and chemical properties of the particles, and prolonged exposure to high levels may be hazardous. The study highlights significant knowledge gaps around long-term exposure effects and calls for policy action on microplastic limits in food.
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.
