Microplásticos: Una amenaza creciente para el ambiente y la salud humana
AI summary Read the abstract
Researchers review how synthetic plastic polymers such as polyethylene, polypropylene, and PET fragment into microplastics under 5 mm that are transported through air and water, accumulate in terrestrial and aquatic environments, and pose health risks to animals, plants, and humans through ingestion and inhalation.
Los plásticos son materias primas con los que se desarrollan múltiples productos de uso diario, fundamentales para la producción actual en muchas áreas industriales. La mayoría de los productos plásticos están basados en polímeros sintéticos como el polietileno, polipropileno y PET, resistentes a la degradación por microorganismos, y que, en su lugar, se fragmentan en piezas más pequeñas. Cuando estos fragmentos alcanzan un tamaño menor a 5 mm se les denominan microplásticos (MP). Los MP son transportados por el agua y el viento, llegando a contaminar el ambiente terrestre y acuático. Pueden ser fácilmente inhalados e ingeridos por medio del consumo de agua y alimentos, tanto por animales, plantas y el ser humano. Por tanto, los MP son un riesgo potencial para la salud humana, así como de la flora y fauna, ya que se ha demostrado que pueden dar origen a bioacumulación, problemas de reproducción, crecimiento, metabólicos, entre otros.
