ON October 31 to December 8, several of us (Shizhen, Jun, Gan, Jabir, Habib) attended the 45th International Symposium on Halogenated Persistent Organic Pollutants, also known as Dioxin2025, in Atalaya, Turkey. Shizhen, Gan and Jabir gave oral presentations and each chaired a session; Jun manned a nice poster. We met many ‘old’ friends and former group members, including: Paramita and her students from India, Tom Harner and Perihan who were previous PhD students of Kevin Jones, as Shizhen was, Roland Weber. We stayed in a nice hotel and enjoyed the 7 days symposium. We also took opportunity to visit Istanbul . Strong exotic experience and nice science and social events!
