Rezumat

Air pollution is a serious global problem, closely related to the ecological situation, economy and human health. The moss biomonitoring technique was used to provide an assessment of the air quality throughout Georgia. Starting from 2014, Georgia participates in the Moss Surveys carried out in the framework of the UNECE ICP Vegetation (https://icpvegetation.ceh.ac.uk/) on air pollution in Europe. The first moss surveys in Georgia were undertaken in 2014-2017 [1-3] and the results are included in the Report on the European Moss survey 2015–2016 [4]. In the summers of 2019-2021 new moss surveys were undertaken in Georgia. Four moss species (Hylocomium splendens (Hedw.) Schimp. (n=6), Hypnum cupressiforme Hedw. (n=25), Pleurozium schreberi (Brid.) Mitt (n=7), and Abietinella abietina (Hedw.) M. Fleisch) (n=14)) were collected from 52 locations. Concentrations of 41elements (Na, Mg, Al, Cl, K, Ca, Sc, Ti, V, Cr, Mn, Fe, Co, Ni, Zn, As, Se, Br, Rb, Sr, Zr, Mo, Sb, I, Cs, Ba, La, Ce, Nd, Sm, Eu, Tb, Yb, Hf, Ta, W, Th, U, Cu, Cd, and Pb) were determined by two complementary analytical techniques, epithermal neutron activation analysis (ENAA) and inductively coupled plasma atomic emission spectroscopy (ICP-AES). Principal Component Analyses was applied to show the association between the elements in the study area. Geographic information system (GIS) technologies were used to construct distributions maps of factor scores over the investigated territory. The concentrations were compared with the previous surveys in Georgia and corresponding values in the literature. The obtained data may serve a baseline data for the deposition of air pollutants and follow up possible dynamics of the air quality in Georgia.
