Symposium

Announcement and Call for abstracts

4th EnvironChemTox (MCT) symposium

‘Environmental occurrence, hazard and risk of PFASs’

With keynote by Professor Hans Peter Arp
(Norwegian University of Science and Technology and Norwegian Geotechnical Institute)

When: Thursday 25th September 2025

Where: Vrije Universiteit Amsterdam

Following the successful editions in 2022, 2023 and 2024, we will organize a fourth PFAS symposium in 2025.

For this symposium, we would like to invite all colleagues interested in presenting their work on the environmental occurrence, fate and exposure, bioaccumulation, and the possible eco(toxico)logical risks of PFASs to submit an abstract.

The abstract should be no longer than 2500 characters (excluding title, name(s) and affiliation of presenters, and 4-5 keywords). Please send your abstract before 20th June 2025 to kees.van.gestel@vu.nl and please indicate:

  • If you are not interested in an oral presentation but only want to present a poster.
  • Which of the following topics best fits your abstract:

Symposium topics:

  1. PFAS environmental monitoring and analytical issues
  2. PFAS environmental fate and bioaccumulation, including uptake in food chain
  3. Ecotoxicological effects of PFAS
  4. PFAS environmental risk assessment

Abstracts will be evaluated by the organizing committee, which will prepare a final program to be published by 15th August 2025. Registration for the symposium will open end-August and close 18th September 2025.

Organizing committee:
Kees van Gestel (VU; NWO/TTW-project 187125)
Ayesha Siddiqa (WUR)
Thimo Groffen (University of Antwerp)
Stefan van Leeuwen (WFSR and KNCV-Section MCT)

Hans Peter H. Arp, NGI, is an environmental chemist interested in how fundamental aspects of physical chemistry can be utilized as applied tools for understanding and preventing pollution exposure. His projects focus on designing solutions through policy mechanisms, chemical properties, interdisciplinary collaboration, and sustainable technologies to enable the circular economy and help create a zero-pollution society. He holds a PhD from ETH Zürich (2008) and a professorship at the Norwegian University of Science and Technology (since 2018). He is an Associate Editor for the journal Environmental Science: Processes and Impacts (since 2024).
