The Stockholm Convention’s POPs Review Committee (POPRC) has asked for comments on the latest version of the indicative list of substances covered by the listings of:
- Perfluorooctanoic acid (PFOA), its salts and PFOA-related compounds under the Stockholm Convention
- Perfluorohexane sulfonic acid (PFHxS), its salts and PFHxS-related compounds under the Stockholm Convention
- Long-chain perfluorocarboxylic acids (LC-PFCAs), their salts and related compounds under the Stockholm Convention
We published a call for comments on this topic in 2025. The list has since been updated and we invite you to provide comments on the latest version.

Background
The UK is a party to the United Nations’ Stockholm Convention on persistent organic pollutants (POPs).
POPs are substances that persist in the environment, accumulate in living organisms and pose a risk to our health and the environment. They can be transported by air, water, or migratory species across international borders, reaching regions where they have never been produced or used.
