On March 5, 2022, China issued a notice to publicly solicit comments on the proposed amendment to the Stockholm Convention on Persistent Organic Pollutants (POPs) for PFHxS, its salts and PFHxS-related compounds. The deadline for comments is March 25, 2022.
Stockholm Convention on POPs is an international environmental treaty signed on May 22, 2001, and effective from November 11, 2004 in China. Initially, the Convention targeted on 12 key POPs, which were listed in Annex A (Elimination), Annex B (Restriction), and Annex C (Unintentional production). Later, the Conference of the Parties (COP), by its decisions, amended Annexes A, B and C to the Convention to include additional POPs. So far, there are 30 POPs listed in the Annexes to the Stockholm Convention.
At the tenth meeting to be held in June, 2022, the COP to the Stockholm Convention will consider listing PFHxS, its salts and PFHxS-related compounds in Annex A to the Convention without specific exemptions. An indicative list of PFHxS, its salts and PFHxS-related compounds will be prepared to facilitate the identification of substances.
