Evaluación del potencial de retención de microplásticos en SUDS maduros
AI summary Read the abstract
A feeding trial with juvenile red swamp crayfish determined that 37,818 IU/kg dietary vitamin A was optimal, maximizing growth, antioxidant enzyme activity, intestinal morphology, and digestive enzyme function while minimizing liver stress markers. Understanding nutritional requirements of aquatic crustaceans is relevant to microplastic research as crayfish are exposed to microplastics in their environment and dietary interactions may modulate their physiological vulnerability to plastic-associated contaminants.
Este estudio investiga el rendimiento a largo plazo de los sistemas urbanos de drenaje sostenible (SUDS) en la retención de microplásticos (MPs). Se realizaron muestreos de agua y suelo en cunetas vegetadas en Xàtiva, Valencia. Los resultados preliminares muestran la presencia de MPs tanto en muestras de agua como en suelo, siendo las fibras y partículas las formas más comunes de MPs encontrados. Los SUDS han demostrado cierta eficacia en la retención de MPs, aunque los resultados iniciales muestran una reducción del 28.6%. Se requieren más análisis para determinar la eficiencia promedio de esta tecnología en la retención de MPs. En conclusión, este estudio destaca la importancia de abordar la contaminación por MPs en las aguas pluviales urbanas y evaluar el potencial de los SUDS para retener y degradar estos contaminantes.

The role of different sustainable urban drainage systems in removing microplastics from urban runoff: A review
AI summary Read the abstract
Researchers reviewed how nature-based drainage systems like wetlands, bioretention gardens, and permeable pavements can filter microplastics from urban stormwater runoff. These systems capture a significant portion of plastic particles, though smaller fibers remain the hardest to remove, and standardizing detection methods is still needed to compare results globally.
