Influence of Microplastics and Nanoplastics on the Environment and Human Health
Original title: Influência Dos Microplásticos E Nanoplásticos No Meio Ambiente E Na Saúde Humana
AI summary Read the abstract
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.
O plástico é essencial para a vida humana por sua durabilidade, flexibilidade e baixo custo. O microplásticos e nanoplásticos são a fragmentação do plástico, esse material em pequenas partículas pode causar grande impacto ao meio ambiente e a saúde humana, podendo absorver compostos altamente tóxicos como hidrocarbonetos e metais pesados. É comprovada a presença de microplásticos no leite materno, sendo de extrema preocupação, já que pode comprometer as gerações futuras. São encontrados no trato gastrointestinal de peixes, como as sardinhas que podem ser facilmente ingeridas por humanos. Os microplásticos e nanoplásticos são considerados onipresentes, sendo assim, encontrados em todo o mundo. Em síntese todo plástico lançado ao ambiente, principalmente os micros e nano têm grande potencial de causar prejuízos à saúde humana, ao meio ambiente, a ecologia e a economia.

Micro(nano)plastics in the environment: an overview of potential effects on human health
AI summary Read the abstract
This Spanish-language review summarizes in vitro and in vivo evidence on how micro- and nanoplastics (1 µm–5 mm and below 1 µm) accumulate in the human body and trigger adverse biological responses. It emphasizes the growing public health concern as plastic fragmentation accelerates and human internal exposure becomes increasingly documented.
Microplastics as Indicators of Environmental Pollution and Their Effects on Organisms
AI summary Read the abstract
This Portuguese-language review examines microplastics as indicators of environmental pollution and their effects on aquatic organisms. It highlights how improper disposal of plastic waste leads to microplastic accumulation in water bodies, threatening marine and freshwater life.
Exposição a Nano E Microplásticos E Seus Impactos Na Saúde Humana: Uma Revisão Da Literatura
AI summary Read the abstract
This Brazilian literature review (in Portuguese) synthesizes evidence that nano- and microplastic particles can enter the human body through air, water, and food, and migrate to organs including the lungs, liver, brain, and intestines. Health effects on the respiratory, immune, gastrointestinal, and hepatic systems have been documented in both humans and other mammals, with the severity depending on particle type, size, and dose. The review reinforces growing concern that microplastic exposure is a systemic human health issue rather than a localized or minor hazard.
