P9 : Plateforme Mercure


The mercury (Hg) research group at the GET laboratory is a dynamic environment of researchers and students who study the biogeochemical cycle of Hg. Our main focus is the use of Hg stable isotopes as tracers for natural and anthropogenic Hg sources and Hg cycling. We explore the Hg cycle from emissions (volcanoes, industries) to atmospheric transformations (Pic du Midi) to the main exposure environments (Arctic, oceans) and exposed populations (children, indigenous people, gold-miners).
