PFOS, its salts and PFOSF:
In 2009, the Conference of the Parties listed PFOS, its salts and perfluorooctane sulfonyl fluoride (PFOSF) in Annex B to the Stockholm Convention (decision SC-4/17). To facilitate the implementation of the Stockholm Convention with regard to newly listed POPs, the Conference of the Parties adopted a work programme, including on PFOS, its salts and PFOSF (decisions SC-4/19, SC-5/3 and SC-6/7). In 2019, following the evaluation of the continued need for PFOS, its salts and PFOSF, the Conference of the Parties amended Annex B to remove several of the specific exemptions and acceptable purposes for PFOS, its salts and PFOSF (decision SC-9/4).
PFOA, its salts and PFOA-related compounds:
In 2019, the Conference of the Parties listed PFOA, its salts and PFOA-related compounds in Annex A to the Stockholm Convention (decision SC-9/12). The Secretariat, in consultation with the POPs Review Committee, developed an indicative list of substances covered by listing of PFOA, its salts and PFOA-related compounds. The list is to be updated periodically.
PFHxS, its salts and PFHxS-related compounds:
In 2022, the Conference of the Parties listed PFHxS, its salts and PFHxS-related compounds in Annex A to the Stockholm Convention (decision SC-10/13). The Secretariat, in consultation with the POPs Review Committee, will be preparing an indicative list of substances covered by listing of PFHxS, its salts and PFHxS-related compounds. The list is to be updated periodically.
Long-chain perfluorocarboxylic acids (PFCAs), their salts and related compounds:
The POPs Review Committee recommended listing long-chain PFCAs, their salts and related compounds in Annex A to the Convention. The recommendation will be considered by the Conference of the Parties at its twelfth meeting in May 2025.
- UNEP/POPS/POPRC.18/11/Add.4: Risk profile for long-chain PFCAs, their salts and related compounds
- UNEP/POPS/POPRC.19/9/Add.2: Risk management evaluation for long-chain PFCAs, their salts and related compounds
- UNEP/POPS/POPRC.20/10/Add.3: Addendum to the risk management evaluation for long-chain PFCAs, their salts and related compounds
- UNEP/POPS/POPRC.20/INF/17: Draft indicative list of long-chain PFCAs, their salts and related compounds
The registers for specific exemptions and acceptable purpose are maintained by the Secretariat on the Convention website.
