Abstract：
Classical monitoring of air pollution provides information on environmental quality but involves high costs. An alternative to this method is the use of bioindicators. The purpose of our work was to evaluate atmospheric aerosol pollution by selected polycyclic aromatic hydrocarbons conducted as part of annual active biomonitoring (\"moss-bag\" technique) with the use of three moss species: Pleurozium schreberi, Sphagnum fallax, and Dicranum polysetum. The gas chromatography-mass spectrometry (GC-MS) was utilized to determine certain 13 polycyclic aromatic hydrocarbons (PAHs). Three seasonal variations in PAH concentrations have been observed as a result of the study. A fire on the toilet paper plant caused an increase of five new compounds: benzo(k)fluoranthene (BkF), benzo(a)pyrene (BaP), indeno(1.2.3)-cd_pyrene (IP), dibenzo(a.h)anthracene (Dah), and benzo(g.h.i)perylene (Bghi) in proximity after 8 months of exposure compared to previous months. The effect of meteorological conditions on the deposition of PAHs (mainly wind direction) in mosses was confirmed by principal component analysis (PCA). Dicranum polysetum moss accumulated on average 26.5% more PAHs than the other species, which allows considering its broader use in active biomonitoring. The \"moss-bag\" technique demonstrates its feasibility in assessing the source of PAH air pollution in a long-term study. It is recommended to use this biological method as a valuable tool in air quality monitoring.
摘要：
传统的空气污染监测提供了有关环境质量的信息，但成本很高。该方法的替代方案是使用生物指示剂。我们工作的目的是通过选择多环芳烃来评估大气气溶胶污染，这是年度活性生物监测（“苔藓袋”技术）的一部分，并使用三种苔藓物种：胸膜，Flax泥岩,和多夫根草。气相色谱-质谱（GC-MS）用于确定某些13种多环芳烃（PAHs）。作为研究的结果,已经观察到PAH浓度的三个季节性变化。卫生纸厂的火灾导致五种新化合物的增加：苯并（k）荧蒽（BkF），苯并(a)芘(BaP),茚诺(1.2.3)-cd_pyrene(IP)，二苯并(a.h)蒽(达),与前几个月相比，暴露8个月后，苯并（g.h.i）和苯并（Bghi）。主成分分析（PCA）证实了气象条件对苔藓中多环芳烃（主要是风向）沉积的影响。多结双株苔藓平均积累的多环芳烃比其他物种多26.5%，这允许考虑将其更广泛地用于主动生物监测。“苔藓袋”技术在长期研究中证明了其在评估PAH空气污染来源方面的可行性。建议将这种生物方法用作空气质量监测的有价值的工具。
