报告题目：2019, the 100th anniversary of the discovery of Hg isotopes - challenges, surprises, opportunities
主讲嘉宾：Jeroen E. Sonke
报告摘要：In 1919 and 1920 Sir Francis Aston at Camebridge University worked his way through the periodic table of the elements. One by one he discovered the isotopes of the elements using an instrument called the mass spectrograph. Since 2001 we use modern mass spectrometers to explore the natural variations in the isotope abundances of Hg. In this talk I will look back at both the long and short history of Hg isotope biogeochemistry. Initially a curiosity among few, Hg isotope signatures are now transforming Hg science, providing insights into longstanding debates on atmospheric Hg deposition, aquatic Hg transformations, or volcanic Hg emissions in the Geological past.
