Li Jing’s new paper entitled ‘High-Resolution Mapping of Fossil Fuel CO2 using Plant Radiocarbon and Bayesian Inversion: towards a City Scale Emission Audit‘ has been accepted for publication in ES&T. Congratulations!
Wang Xiao publishes in ES&T
Wang Xiao’s 王晓 paper titled “Decadal Shifts in PAH Sources and Health Risks in China under Clean Air Actions” has been accepted for publication in Environmental Science & Technology (ES&T). The study integrates radiocarbon analysis of black carbon with positive matrix factorization to clarify long-term source-specific trends of polycyclic aromatic hydrocarbons (PAHs) across China. The findings reveal that while clean air actions significantly reduced coal combustion emissions, traffic-related PAHs have become an increasing contributor to toxicity and health risks, highlighting the need for further energy transition and vehicle electrification. Congratulations to Wang Xiao and the team on this important achievement!

Sun Yanmin retired
On September 29th, Mr. Sun Yanmin (孙彦敏) formerly retired from the position in our group. He has been working on radiocarbon measurement techniques for more than 30 years in the institute, and has been a senior technician since 1998. Mr Sun joined our group in 2021, contributed to the operation and QA/QC of the AMS laboratory, and helped to setup the methodology of tree-ring and plant 14C analysis. We hope Mr Sun all the best in his new life after retirement!
