Hexabromocyclododecane as a possible global POP

The objective of this report is to review the relevant information on a brominated flame retardant hexabromocyclododecane (HBCDD) in relation to the screening criteria of the Stockholm Convention on Persistent Organic Pollutants (POPs) and of the Protocol on Persistent Organic Pollutants of the UNECE Convention on Long-Range Transboundary Air Pollution for adding new substances to these instruments. Some additional information needed in the consideration of the possible nomination of the substance as a new POP is also provided. This joint Nordic project has been prepared by consultant Johanna Peltola-Thies and supervised by a project group under Bjørg Fjeld from the Norwegian Pollution Control Authority. The project was financed by the Nordic Council of Ministers through the Nordic Chemicals Group and the Nordic Sea and Air Quality Group.




Hexabromocyclododecane (HBCDD) is the third most used brominated flame retardant globally, whereas the main share of the market volume is used in Europe. Although HBCDD has not yet been studied by the scientists to the same extent as polybrominated diphenylethers (a group of brominated flame retardants consumed in a larger global volume than HBCDD), the knowledge of the substance properties and of its abundance in the environment has increased during the last decade to such an extent, that some alarming consequences of the production and use have become visible. As a result, the substance was under the Existing Substances Regulation (93/793/EEC) of the European Union already concluded to be of very high concern due to its persistent, bioaccumulative and toxic (PBT-)properties. PBT-substances are foreseen in Europe to be subject to minimisation of emissions.
