Topic description

The RÉSILIENCE project aims at studying the mobility of metallic trace elements (MTE) and antibiotic pharmaceuticals (emerging contaminants) simultaneously present in soils amended with organic wastes (OW). Indeed, pharmaceuticals and MTE are co-present in OW applied onto soils (biosolids, digestates, manures…) and are likely to interact together by coordination complex formation. Their simultaneous presence can thus modify their respective behaviour in amended soils and therefore their mobility and (bio)availability towards the water and biota compartments. The studies carried out within the framework of the RÉSILIENCE project, via sorption experiments in batch and column will allow us to assess (i) the amendment impact on the contaminant retention and transfer in soils, depending on the OW nature and origin and on the composition of the receiving soil, (ii) the influence of antibiotics on MTE retention/transfer in amended soils, and reciprocally, the influence of MTE on antibiotic retention/transfer. To get a better insight into the sorption processes, molecular scale studies will be conducted notably using synchrotron-based techniques. The RÉSILIENCE project is related to the ecodynamics of contaminants present in amended soils in the context of multi-contamination (« cocktail effect »).

The thesis will take place at the Molecular Chemistry Institute of Reims (ICMR UMR CNRS 7312) in the Environmental Chemistry group at the University of Reims Champagne-Ardenne.
