I'd be happy to comment on that. When we spoke earlier about the various facets of a strategy, it is the assessment and the risk management, but it also is research and ongoing science, some of which we get internationally, but others of which we do actually here in Canada. The maternal-infant research on environmental chemicals is a study of that nature and we think it's very important.
I think we're all particularly thoughtful about the particular risks for pregnant women, for example, in terms of those risks from environmental exposure to heavy metals. This is a cohort study that has been established. We are in the midst of undertaking that study now. Through that, we believe that we'll be able to have additional information on pregnant women and babies in terms of their exposure to environmental chemicals. That will give us the kind of research that might then again inform future action.
