Earlier this spring I read news reports of studies that had been conducted by Environment Canada, I think by Dr. Liggio. I imagine there was collaboration external to government on the issue of secondary organic aerosols and air pollutants that were being found in heretofore unknown high levels emanating from the oil sands. In particular, they were measuring 45 to 84 tonnes per day of these secondary organic aerosols, which is the same range as what is produced by Toronto, which is around 67 tonnes per day. These chemicals cause lung cancer, heart disease, diabetes, etc.
I wonder if you had any involvement in that or if you know those studies. Can you speak to their relevance in the context of a CEPA review?
