“…However, comparing the recorded in Poland smog episodes with the classic London smog (year 1952), it is easy to notice the difference between the "Polish smog" and London one. It appears mainly in the high-atmospheric pressure weather, with negative temperatures [8], with the inflow of cold continental air masses from Russia, while acidic smog (the so-called London type) arises in foggy weather, at low-atmospheric pressure and temperatures a little above 0 °C. A common inversion of temperature that hinders the dispersion of pollutants in the atmosphere is a common feature.…”

“…after a period of frost and eastern circulation, the inflow of warmer polar-marine masses from the west, periods of high pressure, a lack of cloudiness and weak wind), it turns out that in many areas of the country excellent conditions for the formation of smog, especially "dusty", but sometimes acidic smog, are created as well. The most important characteristic feature of the "Polish smog" is formation under conditions of high pressure and negative air temperatures [8,13]. In winter, it is often associated with cloudless weather, which results in significant night drops in temperature and inversion.…”

In recent years, every winter we face the problem of excessive air pollution in the cities in Poland. This phenomenon is usually called smog and is associated with the concept of acidic smog of London type. However, there is a fundamental difference between the Great Smog of London known from the literature and winter smog episodes in Poland. While in 1952 in London the smog occurred at low atmospheric pressure, in foggy and windless weather conditions, in Poland smog episodes occur most often at the influx of cold, high-pressure air masses from the east in sunny weather. There are also various harmful components of smog - in London it was dust (suspended particulate matter), sulfur dioxide and carbon monoxide, while in Poland it is suspended particulate matter and polyaromatic hydrocarbons, especially benzo(a)pyrene. A common factor is the inversion of temperature in the ground level of the atmosphere. The chemical composition of the “Polish smog” is analyzed in the study justifying the need to distinguish the two types of smog described.

“…Therefore, the main anthropogenic sources of air pollution in Poland are, among others, power industry (SNAP1), non-industrial combustion (SNAP 2) and road transport (SNAP 7) (Table 1). As a consequence, the permissible levels of pollutants, especially dust, are often exceeded [19]. The aim of this analysis was to determine the average hourly variations in concentrations of selected air pollutants, compared to the activity profiles of main anthropogenic emission sources (SNAP1, SNAP2, SNAP7) in the given areas.…”

Concentration of air pollution in urbanized and agricultural areas is related to the activity of various economy sectors (the so-called SNAP categories). Therefore, the change in the emission of pollutants by an anthropogenic source should result in a change in the air pollution level in the selected area. To better understand the nature of changes in air pollution concentration in urban and agricultural areas, an analysis of data of five-year (2012-2016) air quality measurements, carried out at selected automatic air quality monitoring stations in Poland, Europe. The data came from stations located in 5 regions (Lower Silesia, Greater Poland, Lodz, Masovia and Lublin) in central Poland. The average hourly concentrations in selected areas in cities, towns and villages were compared with the hourly emission factors of power generation sector (SNAP1), residential and commercial combustion sector (SNAP2) and road transport sector (SNAP7). The hourly profiles of air pollution level were expressed by means of the “imission factor”, as analogous to the hourly profiles of the “emission factor” that is being used in the LOTOS-EUROS and the CHIMERE chemistry-transport models.

“…Urban areas generally have high density of buildings, which is associated with a high population density and small vegetation area. Large share in air pollution have areal and linear sources, and air quality is often considered to be low there, negatively affecting human health [11][12] and therefore requiring improvement [13][14]. At the same time, significant amounts of air pollutants are emitted from industrial boiler plants and power stations, as well as combined heat and power plants, located in the city [15].…”

The operation of large power plants, including power stations, and combined heat and power stations, causes the emission of significant amounts of gaseous pollutants into the environment. As a result, in the urban and agricultural areas occurs a pollution of undesirable gaseous substances, such as nitrogen and sulfur oxides. This is especially dangerous for living organisms, soil and water, because, in combination with water vapor, these pollutants are the cause of acid rain. In addition, nitrogen oxides participate in the formation of ground-level ozone, which affects both human health and the condition of existing vegetation. Therefore, the distribution of air pollutants (NO2, SO2 and O3) in the selected urban and rural areas, under the influence of power plants, located in the Lodz Voivodeship, in Poland, in Central-Eastern Europe, was analyzed for a 10-year period (2007–2016). As a result, it was possible to evaluate the impact of the entry into force of Directive 2008/50/EC of the European Parliament and of the Council of 21 May 2008 “on ambient air quality and cleaner air for Europe” on the changes in emissions and concentrations of pollutants in selected locations. As a result of the analysis, a significant decrease in the concentration of SO2 (by 75% in the urban area and by 59% in the rural area), and small changes (from - 8% to + 12%) in NO2 and O3 concentrations in ambient air were found. This indicates the effectiveness of actions aimed at reducing SO2 emissions, however the influence of the power plants on the concentration of air pollutants in these areas is not clear. At the same time, considering the criterion of permissible concentration of ozone and nitrogen dioxide, although the air quality did not improve, the air quality index can be considered as being in the category of "good".

Abstract: Abstract. In recent years, in the winter season we are alarmed about the poor air quality in Poland and significantly exceeded permissible concentrations of certain pollutants, especially PM10 and PM2.
