So for certain health hazards that are presented by certain classes of compounds, I would suggest they need to be defined by what the precautionary principle means. It means that for those classes of compounds, we shall take the following actions: A, B, C, D. The debate is about what those actions are going to be. Right now, we don't even have the requirement to take any action. So whether it's labelling or banning or restricting, which are the lists of possibilities, then we need to have a discussion about what the list should look like for certain classes of compounds.
