The European Commission has adopted the delegated acts for listing two additional groups of substances in the Annex I of the Persistent Organic Pollutants (POPs) Regulation:

• Long-chain perfluorocarboxylic acids (C9-21 PFCAs), their salts and related compounds (7 September 2026); and
• Medium-chain chlorinated paraffins (MCCPs) (11 September 2026).

The European Parliament and the Council of the European Union have two months to formulate any objections before the acts are published in the Official Journal.

The delegated act for listing Chlorpyrifos in the Annex I of the POPs Regulation was published in the Official Journal on 10 September 2026.
