My first question is what kinds of tests were done?  Was there
atomic spectroscopy done, FAAS or FFAAS, etc.? or Gas
Chromatography?  You might contact my colleague, Dr. Pete Palmer at
the Biochemistry and Chemistry Dept. at San Francisco State
University. We have been working on a variety of samples for trace
elements, etc.  He might be able to give you some ideas.
