Search for a possible correlation between geographical area of domicile and trace element composition of human blood serum as determined by pixe

An investigation was undertaken to measure the trace elements in the blood samples by particle induced X-ray emission (PIXE). From the measured concentrations an attempt was made to group the blood specimens by pattern recognition methods as a first step in the search for a possible correlation between the geographical area of domicile and trace elemnt composition. The trend indicated that children with lower Fe and Br contents were similar in their trace element pattern, were predominantly from two district, had lower ferritin values and were breast fed longer than the remaining children in the survey.
