Exposição a Nano E Microplásticos E Seus Impactos Na Saúde Humana: Uma Revisão Da Literatura
Summary
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.
Resíduos plásticos degradam-se em pequenas partículas ais quais podem ser transportadas pelo ar, água e alimentos. Tais partículas podem entrar e sair de nossos corpos e de se deslocarem para órgãos internos, como pulmões, fígado, cérebro, intestinos. Os efeitos negativos sobre a saúde nos sistemas respiratório, hepático, imunológico e gastrointestinal foram relatados em humanos e outros mamíferos em resposta a exposições elevadas a essas partículas, sendo dependentes do tipo, tamanho e quantidade dos plásticos expostos. Esta revisão integrativa da literatura teve como objetivo evidenciar os impactos negativos sobre à saúde decorrentes da absorção direta ou indireta a nano e ou micropartículas de plásticos pelo organismo. Foram realizadas buscas por artigos sobre o tema nas bases de dados PubMed, Medline e BVS (Biblioteca Virtual em Saúde), por meio dos descritores: Microplástico; Nanopartículas Plástica; Inflamação; Toxicidade; Risco de Vida; Avaliação de Impacto de Saúde, utilizando os operadores Booleanos “AND” e “OR” para o cruzamento desses entre si. Como critérios de inclusão, foram admitidos aqueles nas línguas portuguesa, inglesa ou espanhola, publicados entre 2011 a 2022, com texto completo e acesso aberto e gratuito, além de obedecerem à temática proposta. Concluiu-se que à exposição humana a esses detritos pode comprometer a homeostase do organismo. Verificou-se que o número de estudos de biomonitoramento ou aqueles envolvendo modelos in vivo é escasso, e a maioria da literatura se concentra-se em modelos experimentais de linhagens celulares in vitro para avaliar o risco potencial a essa exposição. Outros estudos são necessários para ampliação desse entendimento.

The Impact of Microplastics on Human Health: a Comprehensive Review
This comprehensive review summarizes how microplastics — found in air, water, and food — enter the human body through ingestion, inhalation, and skin contact, and have been detected in organs including the lungs, liver, kidneys, placenta, and brain. Microplastic exposure has been associated with respiratory disorders, gut inflammation, reproductive toxicity, immune dysfunction, and potential neurological effects.
Repercussões dos microplásticos e nanoplásticos nos sistemas gastrointestinal, circulatório e respiratório: Um novo potencial de exposição
This integrative review examined the effects of microplastics and nanoplastics on the gastrointestinal, circulatory, and respiratory systems, drawing on studies indexed in PubMed, SciELO, LILACS, and Cochrane databases. The review summarized the routes of contamination and health consequences of plastic particle exposure for these major organ systems.
A review of data for quantifying human exposures to micro and nanoplastics and potential health risks
This review synthesizes data on human exposure to micro- and nanoplastics through air, water, and food, and examines the potential health effects. Researchers found evidence of respiratory, liver, immune, and gastrointestinal impacts in humans and mammals exposed to elevated plastic particle levels, with toxicity varying by plastic type and size. The study highlights that while growing evidence links plastic particle exposure to health concerns, significant data gaps remain in quantifying actual human intake and long-term risks.
