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.

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 Impact

The course of the <i>Artemisia</i> pollen season was recorded in Lublin over a period of five years: 2001-2005. The volumetric method was applied in the studies, using a VPPS 2000 Lanzoni trap. The length of the season was determined by the 98% method. The impact of several meteorological factors on the start and course of the pollen season was analysed. It was found that in the five-year period studied the mugwort pollen season started in the second or third decade of July and lasted 59-90 days. Maximum concentrations in the range of 103-221 pollen grains in 1 m<sup>3</sup> of air were noted between 2 and 9 August. Annual totals of mugwort pollen grains ranged from 1496 to 2532. A significant positive correlation was demonstrated between the <i>Artemisia</i> pollen concentration and air temperature, and a negative correlation between the pollen concentration and air relative humidity and cloudiness. A significant impact of temperature on the start of the <i>Artemisia</i> pollen season was also found.

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 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℃.

Pollen Seasons

In Poland birch belongs to the most important taxa producing allergenic pollen, therefore information on the start dates, duration and severity of the pollen season is very important for allergists and their patients as well as for climatologists. Birch pollen monitoring was conducted in Lublin using the volumetric method during the period 2001-2010. A Lanzoni VPPS 2000 trap was placed at a height of 18 m in the city centre. The pollen season was determined using three methods: 98%, 95%, and 90%. The present study also investigated correlations between the birch pollen season parameters and meteorological factors. A comparison of the above-mentioned methods shows that, in the conditions prevailing in Lublin, the most appropriate method to determine the birch pollen season is the 98% method, since in the case of the two other methods too large quantities of pollen grains are eliminated. Based on a comparative analysis of the meteorological data from the study period and the long-term averages, it can be concluded that in the recent years a clear increase in air temperature has been recorded in Lublin. The study found a statistically significant negative correlation of seasonal pollen concentration with rainfall and air humidity. When the pre-peak and post-peak periods were separated, these correlations were larger and related to different meteorological factors. The start of the pollen season was negatively correlated with temperature in February and March. The season duration depended on temperature (a positive correlation). The date of the seasonal maximum was positively correlated with seasonal temperature and negatively with temperature in April.

AbstractThe goal of this study was to compare hazel pollen seasons in Sosnowiec in 1997–2019 and to analyse the impact of weather conditions on these seasons. The measurements were conducted using a volumetric method with a Burkard spore trap. The duration of pollen seasons was determined using the 98% method. SPI (Seasonal Pollen Index) was calculated as the sum of daily pollen concentrations in a given season. The measurements showed that high temperatures in January and February had an impact on the beginning of the hazel pollen season. They revealed that there are positive correlations with temperatures and sunshine hours long before the season, i.e. 210–180 days before. The daily hazel pollen concentration in Sosnowiec showed a positive and statistically significant correlation with air temperature, sunshine hours, and average and maximum wind speed. Negative correlation was demonstrated for snow cover depth and relative humidity of the air. Daily concentration levels depend also on the type of weather front as well as direction of air mass flow and its type. Variance analysis showed that the highest concentrations of hazel pollen grains were recorded when warm air moves from the south and south–western direction, whereas the lowest ones were noted for air moving from the east, south–east, north and north–east directions. Atmospheric precipitation, snow cover depth, and average, maximum, minimum and near-the-ground temperatures in the season also had an impact on the SPI of hazel pollen grains. High positive correlation coefficients were also observed in the case of thermal conditions, sunshine hours, relative humidity and precipitation from July to September in the year preceding a given pollen season. The duration of the hazel pollen season depends on precipitation, snow cover depth and temperature during a given season.

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.

  The Asteraceae family is one of the largest families, comprising 67 genera and 264 species in Poland. However, only a few genera, including Artemisia, are potential allergenic sources. The aim of the study was to compare the mugwort pollen seasons in Bialystok, Bydgoszcz, Sosnowiec, Lublin, Piotrkow Trybunalski, Opole, Olsztyn, Szczecin, Warsaw and Wroclaw in 2019. The investigations were carried out using the volumetric method. Seasonal Pollen Index was estimated as the sum of daily average pollen concentrations in the given season. The mugwort pollen season is mainly observed in June, July and at the beginning of September. In 2019 the pollen season of mugwort started first in Opole, on the June 26th. At the latest, a pollen season ended in Bydgoszcz and Warsaw, at the end of September. The differences of pollen seasons duration were extremely considerable, from 35 to 83 days. The highest airborne concentration of 97 pollen grains/m3 was noted in Lublin on the July 31st. The maximum values of seasonal pollen count in Polish cities occurred between July 28th and August 12th, most often between in late July and early August. The highest mugwort pollen allergen hazard occurred in 2019 in Lublin, Warsaw, Opole and Wroclaw, and was 2–3 times higher than in other cities. The highest variability in the analysed seasons was found in start date, while the lowest in the peak value and SPI value. In the pollen season in 2019, 2 peaks of Artemisia pollen concentrations were observed as a result of the order of flowering of A. vulgaris and A. campestris. Information on the pollination of various Artemisia species will be used to avoid excessive exposure to allergens of these pollen grains.

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 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.
