Madam Chair, the member raises an excellent point with respect to mixtures. The reality is that the science on that is evolving. Dealing with the potential number of mixtures with literally hundreds of thousands of chemicals is new and evolving science. The tools to do that are really just being developed.
When we spoke earlier about how the science is evolving, we completely agree. We are watching and evaluating that, but those tools are not yet fully developed or robust enough to deal with all the potential scenarios. It is new science that we acknowledge needs to be dealt with, and we are working with international partners to develop those tools to deal with the literally billions and trillions of potential combinations that are possible.
