I would just support what my colleague has said about the precautionary principle. It is something that infuses our work as we go through the risk management set of criteria and as we look to the range of what appropriate tools or measures we should take.
When we look at the impact on human health, we very much include all the possibilities, from banning to mitigating to some other possibilities along that spectrum, as we look at the balance that my colleague has spoken to. From the examples that you raised, we very much err on the side of the precautionary principle informing our thinking, but we do feel that we have a series of tools that can be appropriate and deal with the substances.
I'll pass this on--
