Abstract: A new micro analytical setup based on the scanning nuclear microprobe (MP) was constructed in the Institute of Nuclear Physics (INP) in Cracow, Poland in the framework of Polish-Ukrainian scientific and technical collaboration. The particle induced X-ray emission (PIXE) technique is installed on the MP. The PIXE spectra and corresponding two-dimensional distribution maps (250 × 250 μm²) of chemical elements in thin (80 - 150 μm) sections of the lichen Xanthoria parietina were obtained. Heterogeneity of several elements (trace elements, in particular) distributions is clearly visualized in the maps. The obtained results show that micro-PIXE method can be extremely useful in the investigations of physiological and biochemical processes in a tissue of biological sample as well as in biomonitoring of air quality. The potential possibilities of the Cracow MP are described in the paper.
