Contexte de travail
This work will be carried out within the framework of the ECLAT project funded by the French ANR (https://www.isterre.fr/french/recherche-observation/contrats-de-recherche/projets-anr/article/anr-eclat.html ). The postdoctoral researcher will be recruited at IPREM UMR5254 in Pau (hosting CNRS unit), where he/she will be a member of the Environmental Chemistry and Microbiology Cluster. The Postdoctoral Fellow will be hosted and will carry out his/her laboratory work on 2 sites: at IPREM (CNRS/UPPA, Pau - France) and at ISTerre (CNRS/IRD/UGA, Grenoble - France). To achieve the defined objectives, the project will rely on the research and instrumental facilities of the two host laboratories. These platform has, among other things, the cutting-edge instruments required for the postdoctoral project (clean room, sample preparation room, total and gaseous Hg analyzers, ICP/MS-AES, HPLC/GC-ICPMS, MC-ICP-MS).
