This research presents the contents of K, Ca, Ti, Mn, Fe, Ni, Cu, Zn, Rb, Sr, and Pb in lichen and moss samples used as biomonitors of air pollution collected in Ulaanbaatar city. X‐ray fluorescence (XRF) methods were used, employing for excitation a Pd X‐ray tube with a molybdenum secondary target. Matrix effects were corrected by the use of normalization for the coherent and incoherent scattered peak, in this way the determination is more efficient. For quality control of the results, comparisons were made with results from other certified laboratories. No significant differences were found between the different techniques. The elemental distribution patterns obtained for each metal were associated with different pollution sources, thus contributing to the assessment of air pollution in Ulaanbaatar.
