I have a very quick question. I'd like, if I could, to ask the scientists on the panel a very simple question.
I spent years working on environmental issues, and people used to talk about cumulative assessment, cumulative effects assessment in an environmental context. It's a fledgling area, I think we would agree.
But when it comes to the important questions Mr. Cullen is asking here, when we talk about the need for a cumulative effects assessment on a human body or a child's body or an older person's body, do we know how to do that? Is there established scientific protocol that allows us? Or are we now at a phase where we're pushing out the envelope and we need to begin to understand better how to do that? Do we know how to do a cumulative effects assessment of the important issues that Mr. Cullen is raising here? Do we actually know how to do that? Is there a science-based department, ministry, organization that does cumulative effects assessment for these kinds of products?
