Yes, such studies would be useful, informative, and scientific. Several small-scale versions have been done, with the conclusions I have outlined above, but the funding for such things is extremely limited. If only someone big--like, I don't know, the CDC--could be bothered to look into it.

Unfortunately it's nearly impossible to measure the daily intake of metal, and it's unethical to the extreme to deliberately dose someone with a known poison. However, it's easy to determine normal versus abnormal results: In a normal person, a certain amount of metals can be measured in the urine, and then following a challenge dose of chelation drugs, that baseline amount should stay the same. The drug does nothing because the body is already outputting everything that goes in. If, on the other hand, the drug causes a large increase in the amount excreted, one can assume there is a certain backlog of metals in the body, because you can generally be certain that the individual was not suddenly exposed to such high levels of anything in the previous six hours.
