Microdistribution of lead in bone: a new approach.
A knowledge of the microdistribution of lead in bone is important in order to understand the mechanisms for accumulation and release of lead. The availability of the synchrotron x-ray microscope for sensitive measurements of bone content and distribution of lead provides a valuable tool which, when combined with kinetic, balance, and tissue measurements, can lead to better evaluation of lead toxicity. It may also provide the basis for the development of a suitable model of how lead behaves in the human body. An outline of an experimental protocol for exploitation of the x-ray microscope is given, along with synchrotron x-ray microscope measurements of the distribution of gallium in rat bone that demonstrate the feasibility of the experimental approach.
