The Department for Environment, Food and Rural Affairs (Defra) is seeking comments on draft Stockholm Convention proposals for three chemical substances.

The UK is a Party to the Stockholm Convention on persistent organic pollutants (POPs), substances that persist in the environment, accumulate in living organisms and pose a risk to health and the environment. They can be transported by air, water or migratory species across international borders, reaching regions where they have never been produced or used. Substances listed in the Convention are generally prohibited from production, marketing or use unless exemptions apply or specific acceptable purposes have been agreed.

The POPs Review Committee (POPRC), the technical scientific committee of the Stockholm Convention, has requested information on three substances proposed for listing under the Convention as POPs, specifically on the Draft Risk Profiles (Annex E) for UV-328 (a UV absorber to used to protect surfaces from discolouration and degradation under sunlight) and Dechlorane Plus (a polychlorinated flame retardant) and on the draft Risk Management Evaluation (Annex F) for Methoxychlor (an organochlorine pesticide).

In terms of UV-328 and Dechlorane Plus, comments that support or challenge the evidence in the draft risk profiles that these substance meet the POP criteria are sought. For methoxychlor, comments on alternatives, impacts on society, efficiency and efficacy of proposed control measures, costs and waste disposal are sought.

Comments should be sent to by 18 June 2021.
