Analysis of Lichen and Moss Samples by Using X-Ray Fluorescence Method

As a result of intensive research conducted in recent years in many countries of the world on the selection of advanced analytical methods for continuous monitoring of environmental air pollution, representatives of non-vascular plants such as moss and lichen have been found to be suitable as bioindicators. XRFA method has advantages over other methods in terms of simultaneous determination of many elements, simple sample preparation, and good sensitivity [1]. Research results from many countries show that the method of energy-dispersive X-ray fluorescence analysis (EDXRF) is suitable for elemental analysis of biological and geological samples [2-6]. This study presents the results of determining the contents of K, Ca, Ti, Mn, Fe, Cu, Zn, Rb, Sr, and Pb by EDXRF in moss and lichen samples, collected in the territory of the city of Ulaanbaatar, Mongolia.
