The Stockholm Convention on Persistent Organic Pollutants (POPs) is an international environmental treaty, signed in 2001 and effective from May 2004, which aims to eliminate or restrict the production and use of POPs. Since the adoption of the Convention, the Conference of the Parties has adopted a series of decisions to amend it and to list additional POPs.
The 2019 revised text of the Convention includes the amendments adopted by the ninth meeting of the Conference of the Parties to Annexes A and C, to list dicofol and Perfluorooctanoic acid (PFOA), its salts and PFOA-related compounds to the Convention; and to amend the listing in Annex B to the Convention of perfluorooctane sulfonic acid (PFOS), its salts and perfluorooctane sulfonyl fluoride (PFOSF). Further information on all the chemicals listed in the Annexes to the Stockholm Convention is available here.
