Grass pollen allergens are a frequent cause of pollen allergy in Poland and other European countries. The research on aeroplankton conducted in Lublin since 2001 allows characterization of the course of grass pollen seasons and estimation of the effect of maximum and minimum temperatures, relative air humidity, precipitation and maximum wind velocity on the taxon's pollen concentration. The gravimetric method was used in the study. During the eight-year research period, the pollen season usually started in the first or second decade of May and, as a rule, it lasted till the end of August, and quite exceptionally, in 2002 and 2008 till mid-August. The mean length of the pollen season was 107 days. The highest grass pollen risk was observed in the 26<sup>th</sup> and 27<sup>th</sup> week. The highest annual counts reaching over 3600 pollen grains × cm<sup>-2</sup> were noted in 2008, while in the other study years they ranged from 741 to 1909. The date of the pollen season onset and its course were highly dependent on weather conditions, which was confirmed by the statistical analysis. The greatest significant influence on the pollen season was exerted by maximum temperature, relative air humidity and the maximum wind.

The start and rate of florescence of <i>Alnus</i>, <i>Corylus</i> and <i>Betula</i> are dependent on meteorological conditions. In the present paper we have analysed the effect of mean, maximum and minimum temperature, relative air humidity and precipitation on the onset of the pollen season as well as on its length and annual count of pollen grains in alder, hazel and birch. The measurement of pollen fall was done by the gravimetric methods with the use of Durham sampler. Correlation coefficients were calculated between the determined characteristics of the pollen season and weather conditions. In the six-year research period 2001-2006 it was observed that low temperatures in January produced a delayed start of the pollen season in alder, hazel and birch. The beginning of flowering in these taxa was also influenced by thermal conditions prevailing directly before the season (ca. 10 days). The pollen season of the trees in question tended to be prolonged alongside with the increase in relative air humidity, but it was shortened due to higher temperatures. The volume of alder and hazel pollen release increased together with the rise in relative air humidity and precipitation. The annual counts of birch pollen increased along with rising temperature and decreasing relative air humidity and precipitation in the season.

The dynamics of flowering and pollen release in anemophilous plants and the length of the particular phases depend largely on the geobotanical features of a region, its climate, meteorological factors, biological characteristics of vegetation, and abundance of pollen resources. The aim of the study was to determine the relationship between the flowering phases in eight <i>Alnus</i> taxa and the dynamics of occurrence and abundance of airborne pollen grains as well as the meteorological factors (maximum and minimum temperature, relative air humidity, maximum wind speed, and precipitation). The flowering phenophases and pollen seasons were studied in 2008–2011. Phenological observations of flowering were conducted in the Maria Curie-Skłodowska University Botanical Garden in Lublin and they involved the following taxa: <i>Alnus crispa</i> var. <i>mollis</i>, <i>A. glutinosa</i>, <i>A. incana</i>, <i>A. incana</i> ‘Aurea’, <i>A. incana</i> ‘Pendula’, <i>A. maximowiczii</i>, <i>A. rubra</i> and <i>A. subcordata</i>. Spearman’s r correlation coefficients were calculated in order to determine the relationship between the dynamics of inflorescence development and meteorological conditions. Aerobiological monitoring using the gravimetric method was employed in the determination of <i>Alnus</i> pollen content in the air. The annual phenological cycles in 2008-2011 varied distinctly in terms of the time of onset of successive flowering phases in the <i>Alnus</i> taxa studied, which depended largely on the taxonomic rank and meteorological factors. The following flowering sequence was revealed in the 2008-2011 growing seasons: <i>A. subcordata</i> (December or January), <i>A. incana</i> ‘Pendula’, <i>A. incana</i>, <i>A. maximowiczii</i>, <i>A. rubra</i>, <i>A. glutinosa</i>, <i>A. incana</i> ‘Aurea’ (February or March), and <i>A. crispa</i> var. <i>mollis</i> (April). The study demonstrated that the pollen of the taxa persisted in the air, on average, from mid-December to early May. The mean length of the flowering period, which coincided with various phases of the pollen season, was 17 days. The <i>Alnus</i> pollen season in 2008 started at the end of January and lasted until mid-March. In 2009, 2010, and 2011, the beginning of the pollen season was recorded in the first week of March and the end in the first week of April. The maximum concentration of airborne <i>Alnus</i> pollen was found at the full bloom stage of mainly <i>A. glutinosa</i> and <i>A. rubra</i>. Inflorescence development was most closely related to temperature and relative air humidity; there was a weaker relationship with wind speed and precipitation.

In the years 2008-2011, phenological observations of flowering of male inflorescences were carried out in seven taxa from the genus <em>Corylus</em>: <em>C</em><em>. americana</em>, <em>C</em><em>. avellana</em>, <em>C</em><em>. avellana</em> &lsquo;Contorta&rsquo;, <em>C. avellana </em>&lsquo;Pendula&rsquo;, <em>C. </em>× <em>colurnoide</em><em>s</em>, <em>C</em><em>. cornuta</em>, <em>C. maxima</em>, grown in the Maria Curie-Skłodowska University Botanical Garden in Lublin. Simultaneously, the hazel pollen seasons in the atmosphere of Lublin were analysed using a Durham sampler. The aim of the work was to assess the flowering in seven <em>Corylu</em><em>s </em>taxa in relation to selected meteorological elements and to describe the pollen seasons in the years 2008-2011.<br /> During the study years, the annual phenological cycles in the studied <em>Corylus </em>taxa differed markedly in terms of timing of the onset of the successive flowering phases. During the four years of observations, the earliest beginning of hazel flowering was found at the end of January, whereas the latest – at the end of March. The earliest full bloom took place in the first decade of February, and the latest – in the first decade of April. The end of flowering was reported in February or in the first or second decade of April. Each year, <em>C. avellana </em>was the first to produce flowers and it was subsequently followed by <em>C. americana</em>, <em>C. </em>× <em>colurnoides</em>, <em>C. maxima</em>, <em>C. avellana </em>&lsquo;Pendula&rsquo;, <em>C. avellana</em> &lsquo;Contorta&rsquo;, and <em>C. cornuta</em>. The pollen seasons in the study period began at the end of January, in the second decade of February, or in the first decade of March. The end of the pollen seasons most frequently took place in the first or second decade of April. The length of the pollen seasons ranged from 38 to 49 days, while the length of the flowering periods in the individual taxa was 22 days on average. During the four study years, the onset of flowering in <em>C. avellana </em>and the beginning of the pollen season coincided on the same day, whereas the onset of flowering in the other taxa was usually reported after the beginning of the pollen seasons. The flowering period of <em>C</em>. <em>avellana </em>&lsquo;Contorta&rsquo; and <em>C. cornuta </em>lasted from 5 to 16 days after the pollen season. The development of inflorescences was most closely related to maximum temperature and relative air humidity.

Pollen grains are one of the most important groups of atmospheric biological particles that cause allergic processes. Meteorological factors affect the occurrence of pollen allergen release in the air. In order to shed light on this phenomenon this study compares the ash pollen seasons in Bialystok, Bydgoszcz, Sosnowiec, Piotrkow Trybunalski, Opole, Olsztyn, Szczecin, Warsaw and Lublin in 2019. The investigations were carried out using the volumetric method (Hirst type pollen sampler). Seasonal Pollen Index (SPI) was estimated as the sum of daily average pollen concentrations in the given season. The ash pollination is mainly observed in April. Diagnosis of ash pollen allergy is made difficult due to an overlapping pollination period with Betulaceae and some cross-reactivity with allergens from Betulaceae. It is not clear whether ash pollen is a primary cause of sensitization or whether it is implicated through cross-sensitization to other pollens. In 2019 the pollen season of ash started first in Opole, on the March 9th. At the latest, a pollen season ended in Bialystok, after mid may. The differences of pollen seasons duration were very considerable, from 28 to 50 days. The highest airborne concentration of 190 pollen grains/m3 was noted in Lublin on the April 21st. The maximum values of seasonal pollen count in Polish cities occurred between April 4th and 22nd, most often between April 18th–22nd. The highest ash pollen allergen hazard occurred in 2019 in Lublin, Warsaw, Piotrkow Trybunalski and Bydgoszcz, and was at least three times higher than in other cities. The highest variability in the analysed seasons was found in the peak value and annual total.

The measurements of pollen fall were carried out in Lublin in 1995 - 2000 years by the gravimetric method. The modified Durham sampler was applied, located at 9 m above ground level. On the base of results 6 year observations - the pollen calendar for Lublin was prepared. The following 15 plant taxa were taken under consideration: <i>Alnus</i>, <i>Corylus</i>, Cupressaceae, <i>Populus</i>, <i>Fraxinus</i>, <i>Betula</i>, <i>Quercus</i>, Pinaceae, Poaceae, <i>Rumex</i>, <i>Plantago</i>, <i>Urtica</i>, Chenopodiaceae, <i>Artemisia</i> and <i>Ambrosia</i>. The anemophilous plants' pollen season in Lublin began in half of February and lasted till half of September. First appeared pollen grains of decidous tress' and shrubs, then the coniferous. High values of pollen fall of these plants were noted till the end of May. Start of grass pollen season was recorded from the half of May, and at the latter part of this month, also other herbaceous plants. The highest concentrations of pollen were found in April and May when trees and shrubs pollinated. The highest annual totals were marked for plants of the following taxa: <i>Betula</i>, Poaceae, Pinaceae, <i>Alnus</i>, <i>Urtica</i>.

 Allergic diseases are considered as important human health issues as they substantially restrict many allergic people. Trees such as the plane tree can pose a certain threat to allergy sufferers. Due to the frequent planting of these trees in large cities, their pollen can affect the increase in the frequency of local allergy symptoms. This study compares the plane tree pollen seasons in Poland, in Bialystok, Bydgoszcz, Warsaw, Zielona Gora, Piotrkow Trybunalski, Opole, Olsztyn, Szczecin and in Hungary, in Budapest, Debrecen, Gyor, Kaposvar, Kecskemet, Miskolc, Nyiregyhaza and Pecs in 2019. The investigations were carried out using the volumetric method (Hirst type pollen sampler). Seasonal Pollen Index (SPI) was estimated as the sum of daily average pollen concentrations in the given season. The season ranges from March to May, depending on the geographical latitude. Diagnosis of plane tree pollen allergy is made difficult due to some cross-reactivity with birch, but also alder, hazel, hornbeam, oak, beech, sweet chestnut, and to some extent with grass pollen. In 2019 the pollen season of Platanus started first in Hungary, in Pecs on the April 1st; in Poland the pollen season started in Szczecin and Zielona Gora on the April 4th. At the latest, a pollen season ended in Poland, in Warsaw and Bydgoszcz until May 11th–12th, similarly in Hungary – until May 11th in Budapest and Kaposvar. The differences of pollen seasons duration were very considerable, from 15 to 40 days. Also the differences of the highest airborne concentration especially between both countries were extremely considerable (2105 pollen grains/m3 in Nyíregyháza and 3 pollen grains/m3 in Białystok. The maximum values of seasonal pollen count in Polish cities occurred between April 24th and May 1st, and in Hungarian cities between April 9th and 16th. The highest plane tree pollen allergen hazard occurred in 2019 undoubtedly in Hungary: in Pecs, Kaposvar and Nyiregyhaza, and was ten times higher than in Poland. The highest variability in the analysed seasons was found in the peak value and annual total.

AbstractThe study's main objective was to specify the extent to which weather conditions were related to the course of birch pollen seasons in the years 1997–2020. The impact of atmospheric conditions on the daily concentrations of birch pollen grains, the Annual pollen integral (APIn), and the length of pollen seasons were studied. The dependency between each meteorological condition and various features of the birch pollen season was determined using Spearman’s rho correlation, the Kruskal–Wallis test, and cluster analysis with the k-means method. It has been shown that the duration of sunshine and average air temperature occurring within 14 days preceding the season has the most significant influence on the beginning of a birch pollen season. The value of daily birch pollen concentrations in Sosnowiec showed a statistically significant positive correlation with the duration of sunlight and the average and maximum wind speed. The daily concentration also depended on the synoptic situation: the mass airflow direction, the type of air mass inflow, and the type of weather front. The near-ground temperature influenced the APIn of birch pollen grains during the period of 14 days before the beginning of the season and the meteorological conditions occurring in the summer of the preceding year such as the maximum temperature, duration of sunlight, the maximum and average wind speed, and the relative air humidity. It was concluded that the length of birch pollen seasons decreased year by year.

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.

Thunderstorm-triggered asthma (TA) can be defined as the occurrence of acute asthma attacks immediately following a thunderstorm during pollen seasons. Outbreaks have occurred across the world during pollen season with the capacity to rapidly inundate a health care service, resulting in potentially catastrophic outcomes for allergicpatients. TA occurs when specific meteorological and aerobiological factors combine to affect predisposed atopic patients with IgE-mediated sentitization to pollen allergens. Thunderstorm outflows can concentrate aeroallergens, most commonly grass pollen but also other pollens such as Parietaria and moulds in TA, at ground level to release respirable allergenic particles after rupture by osmotic shock related to humidity and rainfall. Inhalation of high concentrations of these aeroallergens by sensitized individuals can induce early asthmatic responses which can be followed by a late inflammatory phase. There is evidence that, during pollen season, thunderstorms can induce allergic asthma outbreaks, sometimes also severe asthma crisis and sometimes deaths in patients suffering from pollen allergy. It has been observed that changes in the weather such as rain or humidity may induce hydratation of pollen grains during pollen seasons and sometimes also their fragmentation which generates atmospheric biological aerosols carrying allergens. Asthma attacks are induced for the high concentration at ground level of pollen grains which may release allergenic particles of respirable size after rupture by osmotic shock. In other words, it is a global health problem observed in several cities and areas of the world that can strike without sufficient warning, inducing sometimes severe clinical consequences also with deaths of asthma patients. Due to constant climate change, future TA events are likely to become more common, more disastrous and more unpredictable, as a consequence it is important to have deep knowledge on this topic to prevent asthma attacks. Other environmental factors, such as rapid changes in temperature and agricultural practices, also contribute to causing TA.

In Poland hazel is one of the earliest flowering plants and in phenology it belongs to indicator plants that mark the beginning of early spring. Hazel pollen grains contain allergens that are a cause of pollen allergy during the early spring period. The aim of the present study was to compare Corylus pollen seasons in 2020 in the following 11 cities located in different regions of Poland: Szczecin, Bydgoszcz, Zielona Gora, Wroclaw, Opole, Sosnowiec, Piotrkow Trybunalski, Warsaw, Lublin, Olsztyn, and Bialystok. This research was conducted using the volumetric method and Burkard or Lanzoni pollen samplers. Pollen season duration was determined by the 95% method. This study analyzed the specific parameters of the pollen season (start, end, peak value, peak date, annual total) and also determined the number of days with a concentration exceeding the threshold values at which the first allergy symptoms in people sensitized to hazel pollen and symptoms in all allergic patients occur, respectively. The hazel pollen season in 2020 began relatively early, between January 11th and February 2nd. The season start was recorded earliest in Opole and latest in Olsztyn and Bialystok. The study found that the pollen season started earlier in the western part of Poland than in the eastern regions. The highest maximum Corylus pollen concentration was recorded in Lublin (388 P/m3), whereas the lowest one in Bydgoszcz (48 P/m3). The maximum daily concentration of Corylus pollen grains was recorded in different periods in the individual cities, while the peak concentration values occurred between January 31th and March 4th. The highest risk of allergy in people sensitive to the pollen of this taxon was found in Lublin since the most days with a pollen concentration exceeding the threshold value were observed in this city. Lublin was found to have the highest annual total values and they were 1.6–5.6 times higher than in the other cities. The highest annual pollen sums and peak values as well as the highest number of days with a concentration exceeding the threshold value had also been recorded in Lublin previously.
