Active biomonitoring with wet and dry moss bags was used to examine trace element atmospheric deposition in the urban area of Belgrade. The element accumulation capability of Sphagnum girgensohnii Russow was tested in relation to atmospheric bulk deposition. Moss bags were mounted for five 3-month periods (July 2005-October 2006) at three representative urban sites. For the same period monthly bulk atmospheric deposition samples were collected. The concentrations of Al, V, Cr, Mn, Fe, Ni, Cu, Zn, As, Cd, and Pb were determined by instrumental neutron activation analyses and atomic absorption spectrometry. Significant accumulation of most elements occurred in the exposed moss bags compared with the initial moss content. High correlations between the elements in moss and bulk deposits were found for V, Cu, As, and Ni. The enrichment factors of the elements for both types of monitor followed the same pattern at the corresponding sites.
采用干湿苔藓袋进行主动生物监测，以研究贝尔格莱德市区的痕量元素大气沉降。测试了泥炭藓对大气总沉降中元素的积累能力。在三个具有代表性的城市地点，将苔藓袋放置五个为期3个月的时间段（2005年7月至2006年10月）。在同一时期，每月采集大气总沉降样品。通过仪器中子活化分析和原子吸收光谱法测定铝、钒、铬、锰、铁、镍、铜、锌、砷、镉和铅的浓度。与初始苔藓含量相比，暴露的苔藓袋中大多数元素有显著积累。在苔藓和总沉降物中的元素之间，钒、铜、砷和镍存在高度相关性。两种监测器中元素的富集因子在相应地点遵循相同模式。
