I'm interested in finding a 'compartment/kinetic' model or models for =
heavy metal toxicity that is in the vein of pharmacokinetic models for drugs.
Might you be able to point me to one/some?

Lead appers to be the most studied metal ion, and several models have been
suggested to describe its pharmacokinetics. Pharmacokinetic models have been
suggested also for aluminum, polonium, etc. Several relevant references are
listed below (the references on O'Flaherty model for lead and other metals
have been already sent to the PharmPK, and are not listed here):

I just wrote a basic chapter on Pharmacokinetic Approach and
Mathematical Modeling of Metals for a section "Modeling of trace
element species in health and disease" which soon will be published
in the "Handbook of Elemental Speciation" (edit. Rita Cornelis) by
John Wiley & Sons. Since it is copyrighted and in press, I cannot
send you the manuscript, but here are the synopsis and references
with some Internet sites that you may find useful before the book
hits the shelves.
