Thank you very much. That's a great question.
The whole principle behind the chemical management plan and CEPA and the evaluation that's actively going on and has been going on for a number of years already is to look at both acute risk and, where we have scientific information, chronic risk. We're currently doing that. I'm not going to preclude that it's an easy thing to do. I think others that have testified today have also said that assessing chronic risk is a difficult thing to do. But within the context of the science that's out there, that is currently what Environment Canada and Health Canada are doing to the best of their ability.
