On May 24, 2022, ECHA conducted a public consultation on 5 chemical substance expected to be or have been proposed to include in the list of Persistent Organic Pollutants (POPs). Comments can be made before July 19, 2022.

Once these substances are officially listed in the Stockholm Convention, the European Commission will make amendments to the POPs Regulation according to the Stockholm Convention. The implementation of the POPs Regulation is expected to exert an influence on the manufacture, use and export of products containing these substances. Therefore, enterprises shall take appropriate measures as early as possible.

Detailed information of the 5 substances and their major uses are as follows:

Substance Name

CAS Number

Major Uses

2-(2H-benzotriazol-2-yl)-4, 6-ditertpentylphenol


Often used as UV absorbents in surface coatings, plastic and ink addictive and personal care products; it is also used as UV stabilizers in plastic shrink films, outdoor furniture, and automotive clear coat.

Chlorinated paraffins with carbon chain lengths in the range C14-17 and chlorination levels at or exceeding 45 percent chlorine by weight


Often used as plasticizers in electrical and electronic products; it is also used in cables, wire sheaths, insulating materials, chlorinated rubber resin coatings or copolymer coatings for paints and varnishes, and adhesives and sealants.




Dechlorane Plus and its syn- and anti-isomers




Used as a non-plasticized flame retardant in adhesives, sealants and adhesives.

Long-chain perfluorocarboxylic acids, their salts and related compounds


Used as lubricants, wetting agents, plasticizers and corrosion inhibitors in surface treatment, fireproof and waterproof materials such as textiles, leather, paper, and other special fields.

Proposals for New PoPs

Q: What is the new POPs Proposal?

A: For a new substance to be listed in the POPs Proposal, it shall be listed in the Stockholm Convention or the POPs Protocol.

Q: Who can propose new POPs?

A: Any party to the Stockholm Convention, including the EU, can submit a proposal to add a new persistent organic pollutant to the annexes of the Convention. EU Member States can submit their proposals to the European Commission. Their proposals must enable the substance’s properties to be assessed against screening criteria listed in Annex D of the Convention.
