Canada’s Environment Department has published for consultation draft screening assessments of ten flame retardants, proposing to conclude that three1 [ EBTBP (brominated), TCP (non-halogenated phosphorus ester) and melamine (nitrogen) ] do not pose risk and do not require further action.
Of the remaining seven substances (brominated or chlorinated), three2 are recommended for addition to the Canada List of Toxic Substances, or that they may be potential future concerns if exposure increases in the future. The draft screening assessments for the ten flame retardants are open to consultation to 7th December.
1: EBTBP = 1H-isoindole-1,3(2H)-dione, 2,2′-(1,2-ethanediyl)bis[4,5,6,7-tetrabromo CAS 32588-76-4. TCP = Phosphoric acid, tris(methylphenyl) ester CAS 1330-78-5. Melamine = 1,3,5-Triazine-2,4,6-triamine (Melamine), CAS 108-78-1.
2: TCPP = 2-Propanol, 1-chloro-, phosphate (3:1) (TCPP), CAS 13674-84-5. DP = Dodecane Plus = 1,4:7,10-Dimethanodibenzo[a,e]cyclooctene, 1,2,3,4,7,8,9,10,13,13,14,14-dodecachloro-1,4,4a,5,6,6a,7,10,10a,11,12,12a-dodecahydro- CAS 13560-89-9. DBDPE = Decabromodiphenyl ethane = Benzene, 1,1’-(1,2-ethanediyl)bis [2,3,4,5,6-pentabromo- CAS 84852-53-9
