Watch the webinar video recording on Analytical and Monitoring Methods for PFASs

The OECD Per- and Polyfluoroalkyl Substances (PFAS) webinar series brings world experts together to share vital information and best practices regarding PFASs. These free webinars are open to the general public. Video recordings of our PFASs webinars are made available online afterwards. Register for an upcoming webinar or watch the video recordings of our past webinars below.


On 11 June 2020, the OECD hosted a webinar on the latest developments in analytical and monitoring methods for PFASs. It is important to understand the levels and trends of PFASs in the global environment, biota and in products so as to take relevant measures to reduce environmental and human exposure.

The webinar featured the following speakers:

    • Introduction by Eeva Leinala, Principal Administrator, Environment Directorate, OECD 
    • Shoji Nakayama, Centre for Health and Environmental Risk Research, National Institute for Environmental Studies, Japan presented work on worldwide trends in tracing PFAS in the environment | Presentation
