The 100th Anniversary of the Discovery of Hg Isotopes – Exploration, Application and Opportunities

2019-08-08 153

Dr. Jeroen E. Sonke from CNRS & University of Toulouse, France was invited by Dr. Ruoyu Sun to ISESS for academic exchange and cooperation.

(1) Short course on scientific writing

On July 23, 2019, Dr. Snoke gave a short course about scientific paper writing for students and early-career scientists.

In the morning, he instructed the writing methods, precautions, vocabulary and grammar selection on each part of the scientific paper. He first focused on the title of a paper, which should include the key words and discovery in a science story. Then, he pointed out that the “introduction” needs to present the basic knowledge of research area, the scientific problems and discoveries, and “Materials and Methods” should deal with the problem-solving methods. The data analysis and their intepretation should be included in the “Results and discussion” section. In the afternoon, the abstract of students who are writing scientific papers were analyzed and revised. The importance of the abstract in a paper was emphasized. The abstract contains the background introduction, the basic problems of the research, discovery and conclusions of the scientific problem.

At the end of the course, some writing tips were discussed in detail.

(2) Academic lecture

On 26th July, Dr. Jeroen E. Sonke gave an academic lecture titled “The 100th Anniversary of the Discovery of Hg Isotopes – Exploration, Application and Opportunities”.

Firstly, Dr. Sonke introduced the exploration history of Hg isotopes from the discovery of isotopes, including basic concepts, principles and the measuring technology. This year, 2019, is the 100th anniversary of the discovery of Hg isotopes.

Dr. Sonke then shared the application of Hg isotopes in many environmental and geochemical fields, such as coal-fired plant Hg emissions, anthropogenic Hg isotope emission inventory and atmospheric Hg deposition. The Hg isotopes were also applied to source tracing of biota exposure and food chain Hg dynamics. Now, the scientist started to use the GC-MC- ICPMS to measure Hg isotopes of different Hg compounds in different biota tissues. Dr. Sonke finally pointed out the future potential application of coupled carbon and mercury isotopes of methylmercury.

Dr. Jeroen E. Sonke: CNRS research director (DR2 level) in laboratoire Géosciences Environnement Toulouse (GET), 《Stable Isotope Geochemistry》group leader. He has done many pioneering work on metal (Copper, Zinc, Mercury) stable isotope geochemistry. Currently, he mainly applies mercury isotopes to trace Hg cycling across different earth’s reservoirs. He has published many high quality papers in journals like Nature, Nature Geosci., Nature Commun., PNAS.
