The present work was conducted to obtain and highlight the first comprehensive baseline data on atmospheric deposition of trace elements and to evaluate the air quality in Georgia. A total of 120 moss samples were collected over accessible territories in Georgia in the period from 2014 to 2017. Hylocomium splendens (Hedw.) Schimp., Hypnum cupressiforme (Hedw.), and Pleurozium schreberi (Brid.) Mitt. moss species were analyzed by two complementary analytical techniques: instrumental neutron activation analysis and atomic absorption spectrometry. Concentrations of 41 elements in mg/kg were determined. The concentrations were compared with the corresponding values in the literature and are in a good agreement, except for the concentration of Mg, Al, K, Ca, Ti, and Fe, which were higher than those reported for other countries. The principal component and discriminant analyses were implemented to extract information about the similar geochemical features and to decipher the provenance of the studied elements. The analysis showed that a considerable association of crustal elements and the provenance of elements can be considered as a mixture of geogenic and anthropogenic sources. In addition, the influence of different latitudinal climate zones on the distribution of elements in the atmospheric deposition was observed. The enrichment factor shows considerable values for Th and Zr. The spatial distribution of the pollution load index identifies four zones (#12, 38, 53, and 64). The potential ecological risk index and the risk index were calculated and it does not pose significant risk except As and Cd. The data obtained can be used as the first dataset of metal characterization of air pollution in Georgia.

进行本工作的目的是获得并强调有关大气中微量元素沉积的首个综合基准数据，并评估乔治亚州的空气质量。2014年至2017年期间，在格鲁吉亚的可及区域内共收集了120个苔藓样本。len草（Hywcomium splendens（Hedw。）Schimp）。，Hypnum cupressiforme（Hedw。）和Pleurozium schreberi（新娘）米特。通过两种互补的分析技术分析了苔藓物种：仪器中子活化分析和原子吸收光谱法。测定了41种元素的毫克/千克浓度。将该浓度与文献中的相应值进行了比较，并具有很好的一致性，但Mg，Al，K，Ca，Ti和Fe的浓度高于其他国家的报告。进行主成分和判别分析以提取有关相似地球化学特征的信息并破译所研究元素的来源。分析表明，地壳元素和元素物源之间有相当大的联系，可以认为是地源和人为来源的混合物。此外，观察了不同纬度气候带对大气沉积物中元素分布的影响。富集因子显示出相当大的Th和Zr值。污染负荷指数的空间分布确定了四个区域（＃12、38、53和64）。计算了潜在的生态风险指数和风险指数，除了砷和镉外，它没有构成重大风险。获得的数据可以用作佐治亚州空气污染金属表征的第一个数据集。计算了潜在的生态风险指数和风险指数，除了砷和镉外，它没有构成重大风险。获得的数据可以用作佐治亚州空气污染金属表征的第一个数据集。计算了潜在的生态风险指数和风险指数，除了砷和镉外，它没有构成重大风险。获得的数据可以用作佐治亚州空气污染金属表征的第一个数据集。
