Abstract

The concentrations of suspended particulate matter PM10 in two-month winter period, i.e. December–January in years 2009–2015, were analyzed in relation to the values of wind speed in that time. It was possible to analyze results of air pollution measurements performed in the measuring station from the perspective of their higher levels in winter seasons (so-called smog episodes). Results from 3 stations of the Regional Inspectorate for Environmental Protection in Poznań (WIO? Poznań) served for better presentation of smog episodes in the region (black smog) and aimed at verification of correctness of the measurements of pollution immission in the monitoring station in Piotrkowice which is situated in vicinity of large combustion plant. The analysis confirmed that with low speeds of wind higher values of particulate matter PM10 were observed. The results of the analysis also show the displacement of pollutants according to the current wind direction or their local persistence for a longer time over one area.

冬季风速对大型燃烧厂附近大气颗粒物PM10浓度的影响

分析了2009-2015年冬季12 - 1月两个月的悬浮颗粒物PM10浓度与风速值的关系。可以从冬季(所谓的雾霾发作)空气污染水平较高的角度来分析监测站进行的空气污染测量结果。波兹纳瓦地区环境保护监察局(WIO?(波兹纳瓦)的作用是更好地呈现该地区的烟雾事件(黑色烟雾)，目的是验证位于大型燃烧厂附近的Piotrkowice监测站的污染排放测量的正确性。分析证实，风速较低时，观察到的颗粒物PM10值较高。分析结果还显示了污染物根据当前风向的位移或其在一个区域内较长时间的局部持久性。

期刊介绍： The Journal of Atmospheric Chemistry is devoted to the study of the chemistry of the Earth''s atmosphere, the emphasis being laid on the region below about 100 km. The strongly interdisciplinary nature of atmospheric chemistry means that it embraces a great variety of sciences, but the journal concentrates on the following topics: Observational, interpretative and modelling studies of the composition of air and precipitation and the physiochemical processes in the Earth''s atmosphere, excluding air pollution problems of local importance only. The role of the atmosphere in biogeochemical cycles; the chemical interaction of the oceans, land surface and biosphere with the atmosphere. Laboratory studies of the mechanics in homogeneous and heterogeneous transformation processes in the atmosphere. Descriptions of major advances in instrumentation developed for the measurement of atmospheric composition and chemical properties.
