ANSWER: 30 Apr 2005
Dear Jeannette, I have never heard of any other way of testing a foetus in utero for lead exposure than by the indirect method of testing the mother's blood lead level - the level of lead in the foetal blood and the mother's blood are generally reckoned to be similar enough that the mother's blood, being quite safe to sample and easily collected, is a good surrogate for the foetal blood. As far as I am aware, x-ray fluorescence of lead in patients' bone is only available in the United States and Canada from: Prof David Chettle, Professor, Medical Physics & Applied Radiation Sciences, Department of Physics and Astronomy, McMaster University, Hamilton, Ontario, Canada, phone +1 905 525 9140 ext. 27340 http://www.science.mcmaster.ca/medphys/faculty/33-david-r-chettle.html Prof Howard Hu, Director and Professor of Public Health Sciences, Dalla Lana School of Public Health, University of Toronto, Toronto, Ontario, Canada, phone +1 416 978 8989 http://www.dlsph.utoronto.ca/faculty-profile/howard-hu
The only other XRF that I have heard of closer to Scotland was in a National
Geographic documentary showing the work of Liesbeth Smits, of Smits
