I'm a new subscriber and was hoping someone could help answer a question.
I'm a doctoral student in physical anthropology, and my dissertation topic
will involve stable isotope analysis and the human skeleton. I am
considering examining the variation in isotopic signatures at different
locations within the skeleton, or possibly analyzing bone/teeth/hair/nails
for isotopic signatures as indicators of geographic origin or most recent
area of residence. One of the preliminary questions I am trying to answer is
how does the isotope, once consumed in the form of food/drinking water,
eventually become deposited in bone? I have reviewed biology textbooks,
isotope textbooks, several articles, and performed numerous online searches,
but have been unable to find specific information on the mechanism/pathway
responsible for the incorporation of these isotopes into bone. I'd like to
be able to describe, in detail, what happens to these isotopes once they
enter the body and how they make it into bone. Do you have any suggestions
on where I might look to find the answer? Thanks so much!
