摘要

这项调查的目的是利用 Barbula Indica 苔藓的苔藓生物监测技术和因子分析来评估 Thua Thien Hue 省可能的大气污染源。在越南中部顺化省的 16 个地点采集了 Barbula Indica 苔藓样本。在俄罗斯联邦杜布纳联合核研究所(JINR)的 IBR-2 反应堆中,通过中子活化分析测定了所采集的 Barbula Indica 苔藓样本中 30 种元素的浓度。对获得的浓度进行了因子分析,以揭示可能的污染源。旋转因子载荷表明,有三个因子可以解释 84% 以上的变异性。此外,还计算了因子得分,证实了相应地点存在污染源。

Using Factor Analysis To Find Source Atmospheric Pollution By Moss Technique
The aim of this investigation was to apply the moss biomonitoring technique using Barbula Indica moss and factor analysis to evaluate the possible sources of atmospheric pollution in the Thua Thien Hue province. The Barbula Indica moss samples were collected at sixteen sites in the areas of Thua Thien Hue province, the central Vietnam. The concentrations of thirty elements in the collected Barbula Indica moss samples were determined by neutron activation analyses at the reactor IBR-2 at the Joint Institute for Nuclear Research (JINR) in Dubna, Russian Federation. Factor analysis has been applied to the obtained concentrations to reveal the possible pollution sources. Rotated factor loadings suggested three factors, that could explained more than 84% of variability. Additionally, factor scores were calculated, that confirmed the presence of pollution sources in the corresponding sites.
