Inviter: Lizhi Zhang, Chengliang Mao

Abstract: 

The sources and transformation processes of atmospheric components have significant impacts on the Earth’s climate system and air quality. Isotopic tracing techniques, known for their high sensitivity and source apportionment capabilities, have become an important tool for studying atmospheric chemical processes. This report will focus on recent advances in the application of radioactive and stable isotopes in the study of atmospheric components containing carbon, nitrogen, oxygen, and sulfur, with an emphasis on source identification and transformation mechanisms of aerosols, greenhouse gases, and atmospheric deposition. By comparing the strengths and limitations of different isotopic systems, the report will explore the development trends of isotopic techniques in multi-component analysis and atmospheric pollution source tracing, providing scientific support for a deeper understanding of atmospheric environmental processes.
