On the afternoon of November 5, 2022, at the invitation of Professor Mou Cuicui and Associate Professor Lu Xia from the College of Earth and Environment Sciences of Lanzhou University, Researcher Zhang Qianggong from the Institute of Qinghai-Tibet Plateau Research, Chinese Academy of Sciences, taught a course on "Global Cycling of Persistent Toxics" to our 2022 class of Ph.D. students in Resources and Environment. The topic of this course is Environmental Processes and Historical Changes of Mercury in the Interaction of the Qinghai-Tibet Plateau Geosphere.

Researcher Zhang Qianggong first briefly introduced the characteristics of mercury and the environmental pollution problems it brings and clarified the important influence of the circle interaction in the Qinghai-Tibet Plateau region on the whole Asian region, which led to two scientific questions: (1) the processes of mercury deposition and transport transformation in the plateau cryosphere and related environmental media; (2) the history of mercury pollutants recorded in the plateau cryosphere environment. Around these two scientific questions, the main contents of the environmental processes and historical changes of mercury were developed in turn. Finally, researcher Zhang Qianggong summarized the development trend of climate change characteristics and mercury research in the Qinghai-Tibet Plateau region and gave an outlook, and the students benefited a lot from this course.

Rapporteur Profile:

Zhang Qianggong is a researcher at the Institute of Qinghai-Tibet Plateau Research, Chinese Academy of Sciences, and has been engaged in the research of cryosphere and climate environment for a long time. He has published more than 100 research papers and received the Shi Yafeng Young Scientist Award for Cryosphere and Environment from the Chinese Society of Cryosphere Science in 2017 and was selected as an outstanding member of the Young Innovation Promotion Association of the Chinese Academy of Sciences in 2020. He is now working on the environmental impact of alpine cryosphere change under the Outstanding Young Scientist Fund of the National Natural Science Foundation of China. Report title: Environmental processes and historical changes of mercury in the surface sphere interactions on the Qinghai-Tibet Plateau.
