The aim of the study was to characterize vertical distribution of particulate matter, in an area well known by highest air pollution levels in Europe. A balloon filled with helium with measuring instrumentation was used for vertical observation of air pollution over the fugitive sources in Moravian-Silesian metropolitan area during spring and summer. Synchronously, selected meteorological parameters were recorded together with particulate matter for exploration its relationship with particulate matter. Concentrations of particulate matter in the vertical profile were significantly higher in the spring than in the summer. Significant effect of fugitive sources was observed up to the altitude ∼255 m (∼45 m above ground) in both seasons. The presence of inversion layer was observed at the altitude ∼350 m (120-135 m above ground) at locations with major source traffic load. Both particulate matter concentrations and number of particles for the selected particle sizes decreased with increasing height. Strong correlation of particulate matter with meteorological parameters was not observed. The study represents the first attempt to assess the vertical profile over the fugitive emission sources - old environmental burdens in industrial region.
本研究旨在描述颗粒物的垂直分布，该地区以欧洲最高的空气污染水平而闻名。在春季和夏季，使用充满氦气并配备测量仪器的气球对摩拉维亚-西里西亚大都市区逸散污染源上方的空气污染物进行垂直观测。同时，还记录了选定的气象参数以及颗粒物，以探究它们之间的关系。在春季，颗粒物在垂直剖面上的浓度明显高于夏季。在两个季节中，在约 255 m 的高度（地面以上约 45 m）都观察到逸散源的显著影响。在主要交通负荷源位置，在约 350 m 的高度（地面以上约 120-135 m）观察到逆温层的存在。随着高度的增加，所选粒径的颗粒物浓度和颗粒数量均呈下降趋势。颗粒物与气象参数之间未观察到强烈相关性。该研究首次尝试评估逸散排放源——工业区域旧环境负担的垂直分布。
