Mes activités de recherche se concentrent sur l’analyse des micropolluants organiques (pesticides, médicaments, etc.) dans l’environnement afin d’en renseigner la présence et en comprendre le devenir dans différents compartiments (eaux naturelles, effluents, matrices solides, matrices biologiques, etc.). Ces approches mettent en œuvre des méthodes basées sur la chromatographie (LC, GC) couplée la spectrométrie de masse (MS/MS ou HRMS), ainsi que le développement et l’utilisation d’échantillonneurs passifs. Au LEHNA, dans le cadre du projet PINTES 2, je vais notamment développer et valider des méthodes analytiques afin de caractériser la dynamique de plusieurs micropolluants organiques sur le site d’infiltration de Crépieux-Charmy. Ce site est une interface qui sert à l’infiltration d’eaux de surface dans la nappe alluviale du Rhône, et à ce titre il est important de caractériser transferts potentiels de micropolluants qui peuvent s’effectuer entre les différents compartiments (eau de surface, eau souterraine, sédiments), afin de mieux comprendre le fonctionnement de ce système très dynamique et essentiel à la production d’eau potable.
My research activities focus on the analysis of organic micropollutants (pesticides, pharmaceuticals, etc.) in the environment in order to determine their presence and understand their fate in various compartments (natural waters, effluents, solid matrices, biological matrices, etc.). These approaches involve methods based on chromatography (LC, GC) coupled with mass spectrometry (MS/MS or HRMS), as well as the development and use of passive samplers. Within the framework of the PINTES 2 project, I will specifically develop and validate analytical methods to characterize the dynamics of several organic micropollutants at the Crépieux-Charmy infiltration site. This site serves as an interface for the infiltration of surface water into the Rhône alluvial aquifer, and as such, it is important to characterize the potential transfers of micropollutants that may occur between the different compartments (surface water, groundwater, sediments), in order to better understand the functioning of this highly dynamic system, which is essential for drinking water production.
