On Oct 17-21, Gan and Shizhen first attended the Annual Meeting on Environmental Analytical Chemistry held in 镇江Zhengjiang, then paid academic visits  to 江南大学宜兴校区Jiangnan-U@Yi Xin and 南京大学Nanjin-U. We met many ‘old’ friends on the meeting, and delivered lectures in the two universities. Professors 何锋He Feng of JNU and 钟寰 of NJU were our hosts, respectively.  Gan also met his senior brother 季俊峰Ji Junfeng during his BSc-MSc study in NJU, who showed us the School of Geosciences at the night.  It is a very memorable academic trip!

On September 9-20, Shizhen and Gan attend the International Symposium of Persistent Toxic Substances (ISTPS2026) at Bologna, and subsequently the Dioxin2026 at Riva del Garda in Italy, respectively. Shizhen delivered two talks on the ISTPS and one talk on the Dioxin2026; Gan delivered a keynote speech on the ISTPS and one oral speech on the Dioxin2026.  We met many ‘old’ friends on the meetings. After the two conferences, we paid a two-day short visit to Dr Xie Zhiyong of Helmholtz Centrum  Hereon  located at Geesthacht of Hamburg, Germany, where Gan visited 20 years ago (2007) and Guancai, Zhao Zhen studied.  It has been a nice and fruitful trip.
