The short answer is yes. Certainly that's a program activity of our department. I'm sure Dr. Butler-Jones can elaborate a little bit on that.
Let me say that there is going to be a comprehensive review of the Environmental Protection Act. It is going to be jointly launched by Health Canada and Environment Canada. That will be a real opportunity for us to review the science on this.
There's a lot of evidence that we do have individual traces of chemicals in our bodies, but I'd like to know what the cumulative impact of that is. It's one thing to have 0.01% of chemical A, 0.05% of chemical B, and a trace of chemical C. We might know what A, B, and C do individually, but I think it's incumbent upon us to also worry about what they do collectively in our bodies. That's something that I worry about, and I would like to get some answers on that front.
Dr. Butler-Jones, is there anything else you'd like to add?
