The concentration of 22 metal elements including Mg, Al, Si, P, S, Cl, K, Ca, Ti, Cr, Mn, Fe, Ni, Cu, Zn, As, Br, Rb, Sr, Zr, Ba and Pb in Barbula Indica moss samples collected in 12 different sites in Ha Noi in July of 2018 were determined by Proton Induced X-ray Emission. The obtained results has been used for assessment of heavy metal pollution in the air in Ha Noi region. The factor analysis was applied to the concentration data of 11 interested elements and the possible sources of air pollution have been suggested. The study showed that the PIXE technique is efficient to environmental pollution analysis since it precise, fast and low-cost.
