No, I don't think that's accurate. In the case of all the chemicals that we re-evaluate, we don't take a different approach. We aren't taking a different approach, really, with the imidacloprid or the neonics. We use the same formula, the same sort of paradigm, when we look at this chemical as when we look at any chemical. We look at all the available information, including some modelling data. If we have information on what's being found in the environment, we use all that information.
We do take—and in the legislation we are required to take—a fairly precautionary approach. We do factor into our decision-making an understanding of where there might be uncertainty. We put in safety factors to protect human health, for example. We don't have human data, only animal data, so we are required in our legislation—and it is good science—to understand that there can be some uncertainties in the data.
