Missions
The main missions are participation in field sampling campaigns (French Guiana), implementation of analytical methods adapted for speciation analyses of mercury and other geochemical parameters, their application to water and sediment samples from French Guiana, interpretation of data in an interdisciplinary context and publication writing. All laboratory work will be done at IPREM (Pau) and ISTerre (Grenoble) research facilities.
Activities
• Setting analytical methods
• Sampling and analysis of environmental samples
• Data processing and interpretation
• Presentation of results at conferences
• Writing reports, manuscripts, and publications
Skills
• Doctoral degree less than 2 years before the starting date of the contract
• Environmental and analytical chemistry, Geochemistry

Work Context
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).
