Focus on field campaigns associated with GMOStral-1028 IPEV program from 2012 in Amsterdam Island district, in French Southern and Antarctic lands (framework of international GMOS network)

Mercury (Hg) is a major neurotoxic compound that is dispersed globally in the atmosphere. The human population is mainly exposed to mercury through food (mainly seafood). In 2017, the international Minamata Convention came into force. It aims to limit the use, emissions and health effects of mercury on a global scale. The effectiveness of the Convention in reducing (i) mercury emissions, (ii) mercury concentrations in the environment and, ultimately, (iii) human exposure to mercury will need to be assessed over time. How can the scientific community contribute to assessing the effectiveness of the Convention and the government policies implemented ?

The Global Mercury Observing System (GMOS) is a unique global observing system that aims to provide comparable monitoring data on mercury levels in air and marine ecosystems in both hemispheres to support and meet the needs of the Minamata Convention. This international network provides long-term, high-precision observations from more than thirty ground-based monitoring stations around the world. The GMOStral-1028 IPEV program, which has been running since 2012, proposes to work on improving knowledge of processes and decision-support tools such as models through continuous monitoring (field observations) of atmospheric mercury in several regions of the southern hemisphere, including the sub-Antarctic Amsterdam island station.
