In this study we conducted air pollution monitoring using three different methods: active monitoring with the use of high volume aerosol sampler and biomonitoring with the use of lichens and spider webs. All of these monitoring tools were exposed to air pollution in Legnica city, a region of Cu-smelting in the SW Poland, which is well known for exceeding the environmental guidelines. Quantitative analysis was carried out for the particles collected by the three selected methods and concentrations of seven selected elements (Zn, Pb, Cu, Cd, Ni, As, Fe) were obtained. Concentrations found in lichens and in spider webs were directly compared and indicated significant differences between them, with higher amounts noted for spider webs. Then, in order to recognize the main pollution sources the principal component analysis was conducted and obtained results were compared. It resulted that spider webs and aerosol sampler, despite different mechanisms of accumulation, show similar sources of pollution - in this case - copper smelter. Additionally, the HYSPLIT trajectories and the correlations between metals in the aerosol samples also confirmed that this is the most probable source of pollution. This study can be considered innovative as these three air pollution monitoring methods were compared, which has never been conducted before, and their comparison gave satisfying results.
在这项研究中，我们使用三种不同的方法进行了空气污染监测：使用大容量气溶胶采样器进行主动监测，以及使用地衣和蜘蛛网进行生物监测。所有这些监测工具都暴露在波兰西南部铜冶炼地区莱格尼察市的空气污染中，该地区因超标环境指南而广为人知。对三种选定方法收集的颗粒进行了定量分析，获得了七种选定元素（锌、铅、铜、镉、镍、砷、铁）的浓度。地衣和蜘蛛网中的浓度直接进行了比较，并显示出它们之间的显著差异，蜘蛛网中的含量更高。然后，为了识别主要污染源，进行了主成分分析，并对结果进行了比较。结果表明，尽管蜘蛛webs 和气溶胶采样器的积累机制不同，但它们显示出相似的污染来源——在这种情况下是铜冶炼厂。此外，HYSPLIT 轨迹和气溶胶样本中金属之间的相关性也证实了这是最有可能的污染源。这项研究可以被认为是创新的，因为以前从未比较过这三种空气污染监测方法，它们的比较结果令人满意。
