UK and EU Seek Public Input on Draft Risk Profiles for Polybrominated Dioxins and Furans

The United Kingdom and the European Union have launched public consultations on draft risk profiles for polybrominated dibenzo-p-dioxins and dibenzofurans (PBDD/Fs), including mixed polybrominated/chlorinated dibenzo-p-dioxins and dibenzofurans (PBCDD/Fs). These consultations are part of the process under the Stockholm Convention on Persistent Organic Pollutants (POPs) to evaluate and possibly regulate these substances due to their persistence in the environment and potential health risks.

Background on PBDD/Fs and PBCDD/Fs

PBDD/Fs and PBCDD/Fs are unintentional by-products of various industrial processes, including the combustion of materials containing brominated flame retardants and certain metallurgical processes. Due to their persistence in the environment and their potential to bioaccumulate, these substances are of concern for both the environment and human health.

UK Consultation Details

The UK Department for Environment, Food & Rural Affairs (DEFRA) has published a draft risk profile for PBDD/Fs and PBCDD/Fs and is inviting stakeholders to comment. The consultation period is open from 17 March to 19 May 2025. Stakeholders are encouraged to review the draft risk profile and provide feedback by email to POPs@defra.gov.uk within the specified timeframe.

EU Consultation Details

The European Chemicals Agency (ECHA) has also published a draft risk profile for the same group of substances and is seeking input from interested parties. The EU consultation is open until 20 May 2025 and comments can be submitted here.

Next Steps in the Stockholm Convention Process

Feedback from these consultations will contribute to discussions at the upcoming 20th meeting of the Stockholm Convention POPs Review Committee (POPRC-20), scheduled for 29 September to 3 October 2025. The Committee will review the draft risk profiles and stakeholder comments to determine the need for global regulatory actions on these substances.
