Session 8.7 Biogeochemical cycling of contaminants in the Arctic
Organizers: Lars-Eric Heimburger (GET, Toulouse, France) and Aurélien Dommergue (LGGE, Grenoble, France)

In the past fifteen years, a new instrumentation has opened the door to the analysis of stable isotopes of light elements such as non-traditional Li, Mg or Ca, but also and mainly transition elements such as Fe, Cu, Zn or other heavier elements. Biogeochemical processes are responsible for some of the most important isotopic composition variations among those identified so far for these elements. The ability to unravel processes controlling the mobility, bioavailability and biogeochemical cycling of essential and potentially toxic elements in the terrestrial environment has become a hot scientific topic. This session is an opportunity to make an updated inventory on the use of the isotopic composition of these elements and to show the latest developments, especially in the biogeochemical field.


Session 8.5: Advances in mercury biogeochemistry
Organizers: Jeroen Sonke (GET, Toulouse) and David Amouroux (LCABIE, IPREM, Pau)

Half a century of mercury research has provided scientists and policy makers with detailed understanding of mercury toxicology, biogeochemical cycling and past and future impacts on human exposure. The complexity of the global biogeochemical mercury cycle has led to repeated and ongoing paradigm shifts in numerous mercury related disciplines and outstanding questions remain. In this session we invite contributions that target those outstanding questions on the biogeochemical cycling of mercury.
