About this list

Persistent Organic Pollutants (POPs) listed under the Stockholm Convention, administered by the United Nations Environment Programme (UNEP). The Convention’s annexes target chemicals for elimination (Annex A), restriction (Annex B), or reduction of unintentional release (Annex C) because they persist in the environment, bioaccumulate and harm human health. New substances are added by the Conference of the Parties; this listing reflects amendments current through 2025.
