Abstract
Proton-induced X-ray emission (PIXE) spectroscopy allows simultaneous determination of the concentrations of all biologically essential trace elements and heavier toxic elements in variety of biological and environmental samples. In this report the applications of PIXE for trace element analysis of soils, waters and air particulates will be described. Elevated levels of trace elements in the environment are the result of human activities; very important is the use of fossil fuels and products. PIXE analysis allows the determination of “elemental fingerprint” which in turn helps the identification of pollution sources and pollutants movements. Measurement of trace elements levels in different biological tissues by PIXE reflects the exposure of living beings to elevated levels in the environment. Very useful are measurements of trace elements concentrations in blood, hair and some other tissues.
