Webinar: Why highly persistent chemicals are always a hazard

Scientists are demanding that high persistence be recognised as a hazard in its own right. Watch this webinar to find out why.

Published on 21 May 2026

If it’s not toxic, what’s the problem? It’s an easy assumption to make. But history has proven this view to be wrong on multiple occasions: highly persistent substances have built-in potential to cause harm.

Industry says everything’s okay. Policymakers can’t decide. But scientists are adamant.

Join us for this 45-minute webinar to hear from the experts about why highly persistent chemicals are such a serious a problem.

Highly persistent substances have built-in potential to cause harm.

You can expect to learn about:
✅ The importance of the known unknowns in chemical safety.
✅ What “persistence” means and how it is measured.
✅ The human cost of highly persistent chemicals that turned out to be toxic.

Speakers:
— Martin Scheringer, professor of environmental chemistry at Masaryk University, Czech Republic
— Oliver Loebel, secretary general of EurEau, the European water services association
— Dr. Jonatan Kleimark, director of programmes, ChemSec
