Microplásticos en ecosistemas acuáticos: una revisión sobre su impacto y gestión
This literature review analyzes the ecological impact of microplastic pollution in aquatic ecosystems and available management strategies. Researchers found that microplastics affect aquatic organisms through ingestion and bioaccumulation, altering physiological functions and acting as vectors for toxic pollutants and pathogens. While filtration technologies, bioremediation, and regulatory measures have been developed, their effectiveness remains limited and a comprehensive approach combining prevention, mitigation, and stricter policies is needed.
Unraveling the ecotoxicological effects of micro and nano-plastics on aquatic organisms and human health
This review summarizes the growing body of evidence on how micro- and nanoplastics affect aquatic organisms and, through the food chain, potentially human health. The tiny plastic particles absorb toxic pollutants and pathogens from the water, acting as carriers that deliver these harmful substances into the bodies of fish, shellfish, and other organisms. The review highlights that both direct plastic toxicity and indirect chemical exposure through contaminated seafood pose risks to human consumers.
Influência Dos Microplásticos E Nanoplásticos No Meio Ambiente E Na Saúde Humana
This Portuguese-language review summarizes evidence that microplastics and nanoplastics are now ubiquitous in the environment and in the human body — found in breast milk, fish digestive tracts, and elsewhere — and can carry toxic compounds like hydrocarbons and heavy metals that amplify their harm. The authors highlight particular concern for infant exposure through breast milk and for human ingestion via commonly eaten fish like sardines. The paper reinforces the urgent need for regulatory action to reduce plastic pollution given its demonstrated reach into human biology.
Toxicity of microplastics in the marine environment.
This review chapter provides a broad and updated overview of microplastic ecotoxicology in marine environments, covering effects from the biochemical level through population and ecosystem scales. Evidence reviewed demonstrates that microplastics can act as physical hazards and chemical vectors affecting marine biodiversity across multiple trophic levels.
Effects of micro- and nanoplastics on aquatic ecosystems: Current research trends and perspectives
This review covers 83 studies on the distribution and toxic effects of micro- and nanoplastics in both marine and freshwater ecosystems worldwide. Researchers found that these tiny particles affected the growth, development, behavior, reproduction, and survival of a wide range of aquatic organisms. The paper identifies key research gaps and suggests future directions for understanding the full ecological impact of plastic pollution in aquatic environments.
Microplastics in Aquatic Ecosystems: A Review of Ecotoxicological Effects, Exposure Pathways and Trophic Transfer Risks
This review synthesises evidence on the ecotoxicological effects of microplastics in marine, freshwater, and estuarine environments, covering ingestion, bioaccumulation, trophic transfer, and physiological harms across aquatic fauna. It identifies chemical co-contamination and particle size as key modulators of toxicity.
A review of microplastics in the aquatic environmental: distribution, transport, ecotoxicology, and toxicological mechanisms
This review examines how microplastics are distributed, transported, and accumulate throughout aquatic environments, and the toxicological effects they have on aquatic organisms. The study suggests that microplastics can affect human health through the food chain, but notes that understanding of combined toxicity mechanisms remains very limited. The authors identify significant knowledge gaps and call for more systematic environmental risk assessments across multiple species.
The ecotoxicological impact of microplastics on freshwater invertebrates
This review summarizes the ecotoxicological effects of microplastics on freshwater invertebrates, finding evidence of harm including reduced feeding, growth, and reproduction across multiple species. Because invertebrates are key links in food webs, these effects could have broader consequences for freshwater ecosystems.
Micro Plastics in The Marine Environment: A Review of Their Effects on Marine Organisms and Ecosystems
This review examines the effects of microplastics on marine organisms and ecosystems, summarizing evidence for MP ingestion across trophic levels, physical and chemical harm to marine life, and the pathways through which marine MP pollution threatens biodiversity and fisheries.
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.
A Comprehensive Review on Microplastic Pollution in Aquatic Ecosystems and Their Effects on Aquatic Biota
This comprehensive review examines microplastic pollution across freshwater and marine ecosystems and its effects on aquatic organisms. Researchers found that microplastics are abundant in both environments and that nearly all studies reviewed documented uptake by organisms along with alterations in biochemical parameters. The evidence indicates that microplastic contamination is becoming an increasingly serious environmental and health concern for aquatic life.

Presença e efeitos da poluição plástica em peixes marinhos e de água doce
This thesis (in Portuguese) investigates plastic contamination in freshwater and marine fish, examining physiological, functional, and ecological effects across multiple levels of biological organization, including food safety implications for human consumption.
