Through the Analytical Laboratories of the Subsidiary Management Center for Water Use Technology (SCTUA) of the INA, researchers Silvina Villemoure, Analia Lees, Marta Rimini, Gloria Ciuccio and Dora Vicente presented the work “” of the Water Quality Testing Laboratory. Characterization of waste “”, in turn graduates Valeria Rodríguez Salemi and Marisol Real from the Experimental Laboratory of Sustainable Technologies called “””Biodiality Models and Studies Kinetics. Metal Movement in Excavated Sediments”””.
The AA2023 conference will take place on May 3, 4 and 5 in Potrero de los Funes, San Luis Province. It was organized by the Argentine Environmental Science and Technology Association (SACyTA) and the National University of San Luis (UNSL).
In this edition of AA2023, in addition to the traditional topics that SACyTA addresses in Argentina and environmental meetings, it was necessary to emphasize and propose various technological solutions to address environmental challenges. Therefore, in this way, bring together the national and Ibero-American scientific community interested in environmental and absorption issues, to disseminate knowledge and strengthen collaborative relationships between research groups.
Along these lines, this type of meeting allows for the creation of space for exchange between students, researchers, professionals and related disciplines. Likewise, it promotes interaction with various social agents and socio-productive organization to promote national and regional sustainable development.
Regarding the presentations, the objective of the presentation by Rodríguez Salemi and Real was to study the bioavailability and mobility of heavy metals through sediment reclamation experiments at a site in the Matanza-Riachulo basin. .
In this sense, Real said that during excavations, “the reclamation of sediments, in which pollutants are usually retained, can cause changes in water quality” and “they can affect aquatic ecosystems and the health of people”.
“Study of the impact on water quality during excavation will allow us to know the processes involved in the release of contaminants and their potential bioavailability,” reflects Reale.
Finally, Rodriguez Salemi pointed out that with the information obtained as a result of the investigation, “management recommendations can be made to prevent the water quality from being affected during the purification work.”
About the work “Characterization of liquid wastes generated in the determination of metals by atomic absorption spectroscopy” exposed by INA through CTUA, Silvina Villemour explained “Qualitative and quantitative characterization of liquid wastes generated after a determination”. A group of nine metals in water samples.
Next, Sylvina Villemour stated that the objective of the project is “related to the improvement of liquid waste management” and clarified that “the values obtained must agree with the values allowed by the relevant law according to each jurisdiction”.
Finally, Villemur said that thanks to the development and research of the project it is possible to “propose strategies for the disposal of the hazardous liquid waste generated in this analytical process”.
The project “Bioavailability Models and Kinetic Studies to Assess Metal Mobility in Dredged Sediments” is part of the INA 2021-2023 Strategic Plan and Lic. Rodriguez Salemi’s doctoral thesis. The research is carried out in collaboration with the University of San Martín by the Environmental Research and Engineering Institute and the Hydraulics Department of the Faculty of Engineering of the University of Buenos Aires.
