A study was conducted to investigate the air deposition and explore the distribution of potentially toxic elements in the Mariovo region, North Macedonia, using moss samples as biomonitors of air pollution. The distribution of 44 chemical elements was detected in 20 moss samples collected in the area. The moss samples were analyzed after microwave digestion using inductively coupled plasma - atomic emission spectrometry (ICP-AES) and inductively coupled plasma-mass spectrometry (ICP-MS). It was found that atmospheric deposition for some potentially toxic elements in the moss samples in the study area was influenced only by lithogenic origin. R-mode factor analysis was used to identify and characterize elemental associations. Three factors were separated from the group of macroelements determined by ICP-AES: Factor 1 (Cr, Fe, Ni, V, Al, Zn, Pb, and Li), F2 (Li, Sr, and Ba), and F3 (P, and K); and two associations were separated from the group of trace elements determined by ICP-MS: Factor 1 (Ga, Sc, Ti, Co, Zr, Rb, As, Cs, Ge, Y, Sn, Mo, and rare earth elements - REEs) and Factor 2 (Br, B, Cd, I, and Sb).
开展了一项研究，以调查北马其顿马里沃地区的大气沉降情况，并利用苔藓样本作为空气污染的生物监测器，探索该地区潜在有毒元素的分布。在该地区采集的20个苔藓样本中检测了44种化学元素的分布。苔藓样本经微波消解后，采用电感耦合等离子体原子发射光谱法（ICP-AES）和电感耦合等离子体质谱法（ICP-MS）进行分析。研究发现，研究区域苔藓样本中某些潜在有毒元素的大气沉降仅受岩石成因的影响。采用R型因子分析来识别和表征元素组合。从ICP-AES测定的大量元素组中分离出三个因子：因子1（铬、铁、镍、钒、铝、锌、铅和锂）、F2（锂、锶和钡）和F3（磷和钾）；从ICP-MS测定的微量元素组中分离出两个组合：因子1（镓、钪、钛、钴、锆、铷、砷、铯、锗、钇、锡、钼和稀土元素-REEs）和因子2（溴、硼、镉、碘和锑）。
