As, and Cu. Cluster and Factor analysis with Varimax Rotation was applied to distinguish elements mainly of 20 anthropogenic origin from those predominantly originating from natural sources. Geographical distribution maps 21 of the elements over the sampled territory were constructed using GIS technology. The median values of the 22 elements in moss samples of Albania were high for Al, Cr, Ni, Fe and V and low for Cd, Cu and Zn compared to 23 the many other European countries, but generally were of a similar level as some of the neighbouring countries 24 such as Bulgaria, Croatia, Kosovo, Macedonia and Romania. This study was conducted in the framework of ICP 25Vegetation in order to provide a reliable assessment of air quality throughout Albania and to produce 26 information needed for better identification of contamination sources and improving the potential for assessing 27 environmental and health risks in Albania, associated with toxic metals. 28 29
