I am just going to throw out a suggestion that came to me a few minutes ago. It is much the same as the one my colleague Ben Lobb came up with.
As all the witnesses have said, and as we all agree, lead is first and foremost a public health problem. The public does not object to a certain number of reportable diseases being identified. That goes without saying; they affect everyone's health.
