I think the capacity has to increase, and obviously the announcement on Friday will increase it. We have to recognize that we're dealing with 50 years' worth of backlog from the 20th century, and that's going to take some time and some work and some resources.
Look at the way pesticides are regulated, and even just the capacity in the Pest Management Regulatory Agency, where there are over 300 scientists dealing with 500 active ingredients, which translates into thousands of end-use products. Compare that with what we have now, a short list of 500 and a slightly longer short list of 4,000, out of a pool of 23,000. It's understandable that there's a need for increase in capacity to deal with this.
The other thing to remember in what has been suggested with this notion of materials use, and what I would really like to support in what Paul just said about a class approach, is that there are two very important efficiency measures to deal with these large numbers.
The notion of materials use is an efficiency measure. Instead of having to go after each product, it's going from the basis of the toxicity and saying, don't use it in a whole lot of products; just use it where you really need it, or not at all.
And then, in classes of chemicals it's to reduce the volume of assessments you need to do. We can increasingly draw conclusions about whole classes of chemicals from what we know about the toxicity of a few of them, when we know that they are chemically and toxicologically similar, even if we don't have all the information about each and every one of them—and we never will.
