[Comment] The Government of Canada has inappropriately relied on the weight of evidence based classification of C.I. Pigment Yellow 34 and C. I. Pigment Red 104 by the European Commission and other international agencies, which is not specific to, or appropriate for, an analysis of these two specific pigments [Response] 
The screening assessments for human health are prepared in light of the stated intents of the Challenge, to conduct screening assessments of high priority substances. For these high priorities it is considered appropriate to base information on health hazards principally on weight of evidence based assessments by other agencies. The European Commission classifications were specifically for C.I. Pigment Yellow 34 and C.I. Pigment Red 104. As well, Health Canada’s Priority Substances List assessment on chromium, included consideration of some of the toxicological information on lead chromate and its derived pigments in its evaluation of chromium. The PSL assessment concluded that chromium VI compounds, as a whole, were carcinogenic to humans.
