Plastic waste is an environmental problematic, not only because of its own contamination, but also because it can act as a vector for other pollutants, particularly metals. In this work, taking advantage of the sensitivity of the LIBS technique, the presence of copper in plastics and microplastics present in a stream that receives effluents from a...

This study presents for the first time results about the microplastic concentration and their origin in a stream of the Pampas region in Argentina, receiving wastewater of an intermediate city. The most appropriate procedure to analyze and quantify the microplastics in the studied system is the use of an oxidative digestion process using a 30% H2O2...

Es indudable que el uso de polímeros en el desarrollo de materiales ha dado grandes beneficios a la sociedad. Sin embargo, el uso cotidiano de objetos como prendas de vestir, además de la disposición de millones de toneladas de residuos ha traído consigo la acumulación de microplásticos en diferentes cuerpos de agua (mares, lagos, ríos, arroyos, et...

The hydrodynamic patterns resulting from the combination of tide flow, riverine discharge and bathymetry and their effects on water circulation and sediment transport are studied to assess the impact of geomorphic changes in the Quequén Grande River estuary (Buenos Aires, Argentina). A depth step located at about 2 km from the sea, created by dredg...

Este trabajo tiene por objetivo el análisis de la calidad del agua del arroyo Langueyú para determinar el estado de situación y su relación con la gestión de los recursos hídricos superficiales a nivel local. Se tuvieron en cuenta antecedentes hidrológicos regionales. Se efectuaron recorridos siguiendo el cauce del arroyo desde la cuenca alta, al S...

The Quequén Harbour is located in the south-west of Buenos Aires Province, Argentina, and extends to both sides of the last 2 km of the Quequén Grande River estuary. To provide deep water conditions for navigation, the depth is kept by continuous dredging generating an abrupt step with respect to the thalweg bed further upstream and causing particu...

Quequén Grande River is one of the most important water courses of Buenos Aires Province due to the economic and strategic significance of its estuary, where the populous Quequén-Necochea area and Quequén Port are located. The minor Las Cascadas falls, at 15 km from the place where the river meets the sea is the point where the maximum tidal propag...
