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!

Buqing and Yifan’s paper accepted by JHM

On September 28, Buqing and Yifan’s mew paper  entitled ‘ Elevated Wet Deposition of Micro- and Nano-plastics in Remote Mountains Driven by Free Tropospheric Transport‘ was accepted for publication in JHM. It has been a strong team work led by Shizhen. Bolong collected the samples; Yifan did the sample analysis and primary data curation, while  Jianchu and He Kun helped with analytic practice; Buqing managed to write the manuscript, with Li Jing and Lingxiao helped with drawings and back trajectory analysis, etc. Congratulations!
