I don't deal at that level of the monitoring program. Certainly that is the direction I think most people would feel it should be going. What are the hazards associated with that? To deal with that you have to deal with the risks cumulatively, which is what I was trying to get at. I'm not offering any simple solution here.
The Europeans have started to look at this in a more constructive way. They have several documents from a few years ago when they realized they have to deal with these cocktails to assess these things in a more scientific way. It's not a simple solution; I'm aware of that. It's often multiplicative too.
