Abstract
External beam PIXE analysis with a protonbeam of 2.4 MeV was used to study trace element concentrations in human placentas. The aim was to check the suitability of PIXE analysis regarding soft tissue samples. Sample preparation was kept as simple as possible to avoid contamination or losses due to volatilization. The element of interest /Fe, Cu, Zn, Se, Br, Rb, and Sr/ were easily detected. A comparison was made with placental samples of alcoholics and abstinent controls to determine whether trace element concentrations in the placenta play a role in the pathogenesis of fetal alcohol syndrome.
