Pardon the tangent, but is it true that these toxic metals do have valuable uses?  I don't know much about all the uses for lead and less about cadmium but I do know that we once assumed mercury also had numerous valuable uses but now know that every, (nearly every?) use of mercury can and should be substituted with a less toxic material.  Any substitutes may initially cost more but when we consider the total cost to society perhaps higher initial costs actually become cost savings.
