On Aug 27th, Dr. Roland Weber, independent environmental  consultant for UN Organisations, gave a speech on three continuous topics of “1. International Conventions Relevant for Controlling PFASs and Related Monitoring; 2. PFAS contaminated sites -selected case studies regulatory actions and some lessons learned; 3.Some lessons learned from disposal of low volatile POPs waste and related contaminated sites and risks.”

The lecture mainly focused on the development history of the international conventions on fluorinated compounds and case studies of POPs-contaminated sites. Dr. Roland detailly introduced the production and use process of halogenated compounds (including PFAS, chlorinated compounds and bromine compounds) and recalled the experience and lessons of member states in the process of implementing international conventions. He also proposed more human-health-oriented  (specifically food safety) regulations should be implemented. In the evening, we had a fancy and authentic dinner together and spent a wonderful evening on the Pearl River. Professor Habib came back from Shanghai and joined the events in the afternoon and evening.

On September 28, three of us (Teacher Ma, Lele and He Kun) gave talks showing the recent progress of their work, and the AirOmics Squad members communicated with Roland on a bundle of topics related to POPs. Roland gave very helpful professional comments and advices. In the afternoon, Gan guided Roland and William to visit the Chan Clan’s Academy (陈家祠), and, after Shizhen’s joining in the evening, they climbed up to the top of Guangzhou Tower and enjoyed the splendid night view of Guangzhou.

On September 29, Roland, Shizhen, and Lele flew to Singapore together, to attend the 2024 Dioxin Meeting there.
