Environment Canada has published screening assessment results and final assessment decisions for thirteen of the fourteen substances in Batch 8 of the Industry Challenge. Four of the thirteen substances assessed have been proposed for inclusion on the List of Toxic Substances (“Schedule 1”). These substances are: Propane, 2-nitro-(2-Nitropropoane); Benzene, 1-methyl-2-nitro-(2-nitrotoluene); Phenol, 2,6-bis(1,1-dimethylethyl)-4-(1-methylproply); and Methylium, [4-(dimethylamino)phyenyl]bis[4-(ethylamino)-3-methylphenyl]-,acetate.

The other nine substances assessed did not meet the criteria to be listed as CEPA toxic. These substances are: Methane, nitro-; Glycine, N,N-bis(carboxymethyl)-; Phenol, (1,1-dimethylethyl)-4-methoxy or butylated hydroxyanisole; Benzene, 1, 3, 5,-tribromo-; Benzene, 1,2,3,4-tetrachloro-5,6,-dimethoxy-; Zinc, bis[O,O-bis(1,3-dimethylbutyl) phosphorodithioato-S,S’]-; Fatty acids, C6-19-branched, zinc salts; Benzenepropanoic acid, 3,5-bis(1,1-dimethylethyl)-4-hydroxy-,(1,2-dioxo1,2-ethanediyl)bis(imino-2,1-ethanedityl)ester; Phosphonium, triphenyl (phenylmethyl)-, salt with 4,4-[2,2,2,-trifluoro-1-(trifluoromethyl)ethylidene] bis[phenol] (1:1).
