In his introduction, the Chair noted that pentabromodiphenyl ether had been recommended by the Committee for inclusion in Annex A of the Convention and would be discussed at the fourth meeting of the Conference of the Parties.
Brominated diphenylethers are mentioned as hazardous substances in the list of priority substances for water policy purposes, with the aim of progressively reducing pollution from these substances(European Union, 2000).
Commercially available decabromodiphenyl ether(c-decaBDE) is a polybrominated diphenyl ether(PBDE) formulation consisting of decabromodiphenyl ether(BDE-209,> =90%), with small amounts of nonabromodiphenyl ether and octabromodiphenyl ether.
It will therefore be more practical, rather than listing the commercial mixture C-PentaBDE under the Convention, to list brominated diphenylethers with 4 or 5 bromines.
Accordingly, the Committee agreed to recommend to the Conference of the Parties that tetrabromodiphenyl ether and pentabromodiphenyl ether, being components of pentabromodiphenyl ether commercial mixtures, should be listed in Annex III to the Convention.
In this Decision Guidance Document, typical pentabromodiphenyl ether commercial mixture will be abbreviated as c-PentaBDE and the name of the substance 2,2' ,4,4' ,5-pentabromodiphenyl ether will be abbreviated as PentaBDE.
Pentabromodiphenyl ether The representative of the Norwegian Government introduced the proposal for listing pentabromodiphenyl ether in Annex A to the Convention, and the documentation on the item, listed in annex VII to the present report.
Decides, in accordance with paragraph 6 of Article 5 of the Convention, to recommend to the Conference of the Parties that it should include octabromodiphenyl ether commercial mixtures in Annex III to the Convention as industrial chemicals".
