Micro(nano)plastics in the environment: an overview of potential effects on human health
Original title: Micro(nano)plásticos en el medio ambiente: una descripción de los efectos potenciales a la salud humana
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.
Los plásticos son materiales de enorme importancia en la sociedad actual con aplicaciones en diversos aspectos de la vida diaria, incluida la medicina, la tecnología, el transporte y la construcción. Se utilizan para fabricar una gran variedad de productos (juguetes, electrodomésticos, textiles, envases, etc.), muchos de los cuales son desechados por los consumidores después de un solo uso. Lo anterior, ha generado una gran acumulación de residuos plásticos en el medio ambiente. Una de las principales preocupaciones es su degradación y fragmentación para la formación de microplásticos (1 μm – 5 mm) y nanoplásticos (< 1 μm). Según los hallazgos de estudios in vivo e in vitro, los micro(nano)plásticos pueden acumularse en el cuerpo humano generando algunas respuestas negativas. En este trabajo, se explora la evidencia existente sobre las rutas de exposición humana a micro(nano)plásticos y los posibles efectos en la salud.

Microplastics in the aquatic environment: A look at kinetics, degradation mechanisms, environmental impact, and effects on human health
AI summary Read the abstract
This Spanish-language review examines how microplastics enter aquatic ecosystems, how they degrade over time, and what their environmental and human health effects may be. The authors report that microplastics have now reached even pristine environments like the polar regions, and that their ingestion by diverse organisms raises serious questions about long-term ecosystem health. The review highlights the urgent need for better understanding of microplastic toxicity and fate in water bodies.
