19th POPs Forum in Chongqing

On May 17–18,  Gan, Shizhen, and several members of the Air-Omics group attended the 19th Forum on Persistent Organic Pollutants (POPs), held in Chongqing.

Prof. Gan delivered two invited presentations in separate sessions. In the session on Environmental Behavior and Transformation of Organic Pollutants, chaired by Prof. Sun Hongwen, he presented on the observational study of the coupling between polycyclic aromatic hydrocarbons (PAHs), optical properties, and toxicity in atmospheric particles. In the session on Environmental Fate of Emerging Pollutants in the Atmosphere and Ocean, chaired by Shizhen, Prof. Gan gave a second talk on regional source–sink processes of emerging atmospheric pollutants.

Shizhen shared her latest work on the environmental fate of organophosphate esters (OPEs) in urban air. Lele presented on 6PPD-quinone as a robust marker for tire wear particles: validation and application using nationwide road air samples. Jianchu reported on pollution characteristics and sources of micro/nanoplastics and chlorinated paraffins in Chinese roadside airborne particles. Yifan discussed pollution characteristics, deposition fluxes, and influencing factors of micro/nanoplastics in urban snowfall. Meanwhile, Weiru presented a study on the potential sources and aquatic fate of trifluoroacetic acid (TFA) in typical Chinese salt lakes, in a session focused on short- and ultra-short-chain PFASs.

We were especially delighted to reconnect with several former group members, including Tian Lin, Zhen Zhao, and Ruijie Zhang—turning this academic forum into a warm reunion. For us, the  POPs Forum felt not only like a platform for scientific exchange but also a moment of shared memories and lasting bonds. We sincerely appreciated the heartfelt hospitality from Fengwen Wang and thoroughly enjoyed our time in Chongqing, both academically enriching and personally memorable.

Participation in the 10th Youth Geoscience Forum

From May 9 to 13, Gan, Shizhen, Zhineng, and several former group members attended the 10th Youth Geoscience Forum held in Hefei. Shizhen co-organized and chaired the session on “Emerging Contaminants in the Atmosphere and Ocean” together with Ma Yuxin, Tang Jianhui, and Zhu Ying.

Gan was invited as a special guest and gave a keynote talk titled “An Atmospheric Science Perspective on Emerging Contaminants.” Shizhen also invited Liu Qifan to speak on “Atmospheric Chemistry of Emerging Pollutants” and Xing Xinli to present on “Tire Wear Particles in Road Dust.” Other attendees also gave excellent presentations, contributing to a highly successful and engaging session.

In addition to chairing the session, Shizhen gave a separate presentation on atmospheric microplastics in another session focused on emerging contaminants, further showcasing the group’s research on airborne microplastic pollution.

After the session, the group enjoyed a traditional Anhui-style dinner, where they continued exchanging ideas and strengthening connections in a relaxed setting.

Tian Lele, Ma Jianchu PhD viva and Li Yifan postgraduate viva

On May 8th, Tian Lele (田乐乐) and Ma Jianchu (马建初) had their PhD viva,  also with Li Yifan (李一凡) had her postgraduate viva smoothly. They  are all members of Air Omic’s Squad(爱米小分队). The assessment panel, composed of An Taicheng (GDUT) Zou Shichun (SYSU), You Jing (JNU) ,Chen Duohong (GDEMC), Bi Xinhui (GIG), Ding Xiang (GIG), and, alternatively, Zhao Shizhen ,Li Jun and Zhang Gan. We celebrated with a dinner in honor of the graduates afterwards. We shared a joyful evening, congratulating Lele, Jianchu, and Yifan on their remarkable achievements and wishing them continued success in their future endeavors. Congratulations!
