From 13 to 16 November, Shizhen attended the International Conference on Atmospheric Environment, Extreme Weather, and Health, hosted by Hong Kong Baptist University and invited by Meng Gao. During the meeting, she chaired the session on “Causes and Mitigation of Air Pollution” and delivered an invited talk titled “Atmospheric Transformation of Organophosphate Esters: Evidence for Aqueous Secondary Formation in Aerosols.” 
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!
During September 18–19, several members of the Air-Omics group carried out a field sampling campaign at two industrial emission sites, focusing mainly on electronic circuit source (珠海紫翔&安捷利). The team systematically collected a wide range of environmental samples, including emission air, wastewater, soil, and tree bark, in order to investigate the release pathways and environmental impacts of industrial pollutants. This campaign also represents a key research task under their CAS pilot project, aiming to provide essential data support for understanding industrial sources of emerging contaminants and their environmental behaviors.
