The article presents the analysis results of the grass pollen seasons from 1997 to 2006 in Sosnowiec. The research was carried out by means of the volumetric method with the use of a Burkard device. The duration of the pollen seasons was determined by means of the 98% method. The influence of meteorological conditions on the starting date and duration of the grass pollen seasons has been estimated in the article. The beginning of the pollen seasons was recorded between 23 April and 23 May. It has been demonstrated that the average duration of the pollen season amounted to 138 days. The period of maximum concentrations was recorded in June and the first half of July. The highest daily concentration was found in 2000 (495 grains in m<sup>3</sup>) and the highest annual sums in 2002 and 2000. The daily concentration distribution curve has shown three peaks. The highest values were recorded from 7 am until 11 am, from 13 pm until 17 pm and from 19 pm until 21 pm. It has been found that there is a significant influence of weather conditions (temperature, precipitation and relative humidity) on the beginning and duration of the pollen seasons and the period of maximum concentrations.

Pollen Seasons

The paper refers to the estimation of Poaceae pollen seasons in Poland in selected areas. The aim of the study was to present the long-term variability of the start, end and duration of grass pollen seasons and the seasonal pollen index (SPI) in Poland against a background of the meteorological conditions over pollen seasons. The study was performed in eight Polish cities in 1992–2014 (the common seasons were 2003–2012). Pollen season start was relatively stable in the studied period, the seasons began about the 10th of May, a bit earlier in the south part of Poland. Pollen season ends were more changeable in comparison to the season start and fluctuated from the middle of July to the middle of September. SPI clearly depended on temperature and precipitation in April–August. Daily maximum pollen concentrations were achieved between the end of May and the first decade of July and no evident relationship between this day and weather conditions was found, apart from 2004.

The Relationship

The parameters of the birch pollen seasons in Cracow in 1991-2008 were analysed in relation to some meteorological elements and synoptic situations (circulation types, air masses and atmospheric fronts). Two types of the pollen seasons were distinguished - highly dense and less dense. The first type of the season started on the 15<sup>th</sup> of April (on average), lasted 11-20 days and the maximum daily concentration exceeded 500 pgm<sup>-3</sup>. The less dense type started generally earlier (the first decade of April), lasted more than 20 days and the peak days were unstable. In this type of the pollen season, two peak days were often observed. The relationship between the type of the season and the meteorological conditions before the season was pointed out. Additionally, the influence of circulation types, types of air masses and atmospheric fronts over south-eastern Poland on a given day on the number of days with a daily concentration > 80 pgm<sup>-3</sup> was analysed. The relationship between the pollen season type and meteorological conditions before the season was found, among others, the influence of types of synoptic situations and air masses on the number of days with a concentration of over 80 pgm<sup>-3</sup> was established.

The paper includes the results of pollen season analysis of the selected plants (mugwort, nettle, plantain) regarded as the most allergenic in Wrocław in 2002-2004. The studies were carried out using volumetric method (Burkard trap). The results show strong variation in pollen seasons. The average duration of the pollen season of <i>Artemisia</i> was 82 days. The highest pollen concentration of mugwort was recorded in 2004 (156 grains × m<sup>-3</sup>). The start of nettle pollen seasons varied in studied period on average by 24 days, on average, but its end was almost the same. The pollen season of <i>Urtica</i> was the earliest in 2004. It started on 5<sup>th</sup> May and lasted 136 days. The annual pollen total of <i>Plantago</i> was relatively low, on average 0.2-0.4% in annual pollen totals.

Corylus produces allergenic pollen grains that appear in the air in early spring and cause pollen allergy in sensitive people. The aim of this study was to compare the Corylus pollen seasons in 2021 in the following 11 cities in Poland: Bialystok, Bydgoszcz, Cracow, Sosnowiec, Lublin, Olsztyn, Piotrkow Trybunalski, Szczecin, Warsaw, Wroclaw, and Zielona Gora. This research was conducted using the volumetric method and Burkard or Lanzoni pollen samplers. Pollen season duration was determined by the 95% method. The hazel pollen season in 2021 began relatively late, between February 20 and March 1. The season start was recorded earliest in Zielona Gora, while latest in Olsztyn. The highest values of maximum Corylus pollen concentration were recorded in Sosnowiec (230 P/m3) and Zielona Gora (213 P/m3), whereas the lowest ones in Bialystok (27 P/m3) and Bydgoszcz (54 P/m3). In most of these cities, the maximum daily concentration of Corylus pollen grains was recorded in the third 10 days of February or at the beginning of March and only in Lublin and Bialystok the peak value occurred later, on March 16 and March 26, respectively. The highest risk of allergy in people sensitive to the pollen of this taxon was found in Lublin, Olsztyn, and Zielona Gora. The highest values of the annual pollen integral were determined in Lublin, similarly to the previous years.

The aim of the study was to analyse the grass pollen season dynamics in Wrocław in 2003-2010. The studies were carried out using volumetric method (Burkard trap). Special attentions was paid to differences in pollen season duration and patterns. The pollen season started on average on the 130th day of the year (±10 days) and ended on the 240<sup>th</sup> (±11 days). Peak of pollen seasons occurred between 156<sup>th</sup> and 185<sup>th</sup> day of the year. The mean of SPI value was 2805 (±380). On average, 18 days (±4 days) with a grass pollen concentration of more than 50 grains × m<sup>-3</sup>, and 2 days (±1 day) with concentration of more than 120 grains × m<sup>-3</sup> were recorded during the seasons analysed. Three types of pollen seasons were distinguished on the basis of cluster analysis (the non-hierarchical method of multifeature clustering - the k-means method).

The aim of the study was to compare the dynamics of pollen seasons of selected tree and shrub taxa among measurement sites in Kraków and its neighbourhood. The study was performed in Kraków and Piotrkowice Małe in 2002, as well as in Kraków and Giebułtów in 2006. During the study the volumetric method was applied and pollen grains were counted along four horizontal lines. The lowest percentage of <i>Corylus</i> pollen and the highest percentage of <i>Betula</i> pollen were found in the analysed sites. The differences among start dates in various measurement sites in a given year were inconsiderable. Statistically signifi cant differences of SPI values for the majority of taxa were found between measurement sites and between seasons for Kraków. The pollen season dynamics showed one (<i>Betula</i>, <i>Pinaceae</i>) or more maximum values (<i>Corylus</i>, <i>Populus</i>, <i>Fraxinus</i>, <i>Salix</i>). The occurrence of many peaks could be explained by the appearance of several species within one genus in the studied area or by various weather conditions. In 2002 maximum pollen concentrations were recorded earlier than in 2006. The differences in these dates could be explained better by cumulative temperature >5℃ than >0℃.

An analysis of hazel pollen seasons in Sosnowiec was presented on the basis of data from the years 1997-2007. The research was conducted by means of the volumetric method using a Burkard-type spore trap. The duration of pollen seasons was determined by means of the 98% method. The research demonstrated statistically significant correlations between the average, maximum and minimum temperature, relative humidity as well as the number of days with sub-zero temperature and the beginning of the hazel pollen season. It was demonstrated that the duration of the pollen season depended on air relative humidity, insolation and precipitation during the season and the annual sum depended on the weather conditions of the year preceding pollen production and also the weather conditions two years earlier. Significant correlations were also found between weather conditions and the daily concentration of pollen grains. The daily concentration decreased when relative humidity was high and increased with high insolation and air temperature.

Introduction Allergic rhinitis concerns nearly 25% of the Polish population. Among pollen allergens, the most common reasons for allergic rhinitis are: grass, birch and mugwort. Knowledge of the characteristics of pollen seasons is necessary in diagnostics, monitoring of therapy and prevention of allergic rhinitis. Purpose This work aims to analyze the pollen seasons of the most commonly sensitizing plants in the Polish population; grass, birch and mugwort in the years 2003-2017 in Warsaw. Material and methods Measurements of pollen concentration were carried out using the Burkard volumetric apparatus operating in continuous volumetric mode. The analysis of pollen seasons was conducted based on the following characteristics: beginning, end, and length of season, annual sum of daily pollen concentrations, maximum daily concentration, number of days with maximum and threshold concentration. Linear regression together with the Pearson correlation coefficient were used in statistical analysis to study the relationship between variables; furthermore, descriptive characteristics of distributions studied were determined. Results The average date of the beginning of the birch pollen season in the analyzed period is April 10th, and it belongs to seasons of average length (47 days on average). Concentration above 75z/m3, when most allergic people expect allergic symptoms, was recorded for an average of 18 days. The highest daily concentration of birch pollen reaching 6321 grains/m3 (2006, 2012, 2016) exceeded the lowest value of the maximum concentration by almost 20 times (2015). Among the taxa analyzed, the highest values of daily concentration and annual sums were recorded for birch pollen. The average date for the beginning of grass pollination season is on May 13th. It is the longest pollen season (on average 134 days), and the period when concentration exceeded 50z/m3 covered an average of 26 days. The highest daily concentration of grass pollen reaching 496 grains/m3 (2005 and 2007) exceeded the lowest value of maximum concentration by 3.5 times (2016). The average date of the beginning of the brackish pollen season is July 16th. The season lasts 65 days on average, when concentration exceeding 30z/m3 was registered for an average of 12 days. The highest daily concentration of mugwort pollen reaching 154 grains/m3 (2007) exceeded the lowest value of maximum concentration by 4 times (2013). For all analyzed taxa, the strongest correlated variables are the annual sum of daily pollen concentrations (Seasonal Pollen Index) and daily maximum concentration (correlation for birch pollen = 0.92, for grass pollen = 0.88, and for mugwort pollen = 0.91) Conclusions Periods of pollen in the air show certain variation in the analyzed 15-year period. The maximum concentration in the pollen season for the analyzed taxa and the annual sum of daily concentrations of pollen show the highest variability, particularly strongly expressed in the case of birch pollen. There is a linear relationship between the annual sum of daily pollen concentrations and the maximum concentration value as well as the number of days with the threshold concentration for all analyzed taxa. Variability of parameters describing the dynamics of pollen seasons indicates the need to monitor, both by patients with hay fever and physicians, the current information about the concentration of pollen in the air during the pollen season.

Grasses' pollen produces allergens, which are the main cause of pollinosis in Poland and in many countries of Europe. In Poland the beginning of season falls in different days of May. Pollen monitoring was carried out in Lublin by volumetric method in years 2001-2004 by means of Lanzoni VPPS 2000 trap. Start of grass pollen season was marked by methods 98 % and ∑ 75 as well as by the Clot's method. Differences between them ranged from 1 to 7 days. The most approximate deadlines of beginning of pollen season were qualified according to methods 98 % and the Clot's one, except year 2002. It was defined the pollen season in Lublin begins between 5. and 21. of May. In that study impact of meteorological factors on the beginning dates of pollen seasons was estimated. It was stated statistically positive, essential correlation among the beginning of season and the daily mean, the minimum and maximum air temperature.

Aerosol Properties

Human behaviors probably represent the most important causes of the SARS-Cov-2 virus propagation. However, the role of virus transport by aerosols—and therefore the influence of atmospheric conditions (temperature, humidity, type and concentration of aerosols)—on the spread of the epidemic remains an open and still debated question. This work aims to study whether or not the meteorological conditions related to the different aerosol properties in continental and coastal urbanized areas might influence the atmospheric transport of the SARS-Cov-2 virus. Our analysis focuses on the lockdown period to reduce the differences in the social behavior and highlight those of the weather conditions. As an example, we investigated the contamination cases during March 2020 in two specific French areas located in both continental and coastal areas with regard to the meteorological conditions and the corresponding aerosol properties, the optical depth (AOD) and the Angstrom exponent provided by the AERONET network. The results show that the analysis of aerosol ground-based data can be of interest to assess a virus survey. We found that moderate to strong onshore winds occurring in coastal regions and inducing humid environment and large sea-spray production episodes coincides with smaller COVID-19 contamination rates. We assume that the coagulation of SARS-Cov-2 viral particles with hygroscopic salty sea-spray aerosols might tend to inhibit its viral infectivity via possible reaction with NaCl, especially in high relative humidity environments typical of maritime sites.
