Summary

Microplastics were found in beach sediments along the Río de la Plata near Buenos Aires in both winter and spring surveys, confirming urban plastic pollution has reached coastal environments close to one of South America's largest cities.

Debido a su bajo costo y amplio uso, los plásticos son hoy en día un consumible ineludible. Los efectos de los microplásticos en el medio ambiente es un campo de investigación reciente en Argentina. Durante el invierno y la primavera de 2019 se gestionaron dos campañas de estudio de presencia de microplásticos en sedimentos costeros del Rìo de la Plata: se seleccionaron playas de la Capital Federal y alrededores (AMBA), los sedimentos se muestrearon y caracterizaron. Se confirmó, clasificó y caracterizó la presencia de microplásticos según su morfología y color. Los microplásticos se separaron mediante técnicas de flotación y se identificaron visualmente mediante observación microscópica. La campaña de invierno reportó más ítems de microplástico (un total de 464 sobre los 280 de la campaña de primavera), siendo las fibras y microesferas las más representativas. Si bien este es un trabajo preliminar, los microplásticos encontrados son consistentes con las actividades económicas del área de estudio y la dinámica hidrogeológica de la cuenca del Río de la Plata. El monitoreo debe continuar para elaborar una línea de base ambiental, dilucidar el origen y el destino de los microplásticos e implementar acciones de control.

Assessment of meso- and microplastics distribution in coastal sediments and waters at the middle estuary of the Rio De La Plata, Argentina (SW Atlantic Ocean)

Researchers assessed the distribution of microplastics and mesoplastics in coastal waters and sediments of the Rio de la Plata estuary in Argentina. The study found average concentrations of about 14 microplastic particles per liter in water and nearly 548 particles per kilogram in sediments, representing one of the first surveys of plastic contamination in this ecologically significant South American estuary.
