    Celem pracy było porównanie wartości stężeń zarodników grzybów mikroskopowych z rodzaju Cladosporium w 2007 r. w powietrzu Szczecina, Warszawy, Sosnowca, Olsztyna i Krakowa. Pomiary stężenia zarodników prowadzono metodą objętościową z zastosowaniem aparatu Burkard oraz Lanzoni 2000. Sezon zarodnikowy wyznaczono jako okres, w którym w powietrzu występuje 90% rocznej sumy zarodników grzybów z rodzaju Cladosporium. Sezon zarodnikowy najwcześniej rozpoczął się w Krakowie, zaś w pozostałych miastach nastąpiło to w ciągu kilku następnych dni. Najwyższe wartości stężeń zanotowano w Szczecinie i Sosnowcu, a maksymalne stężenie (21 042 zarodniki × m-3) zaobserwowano w Szczecinie.The aim of the study was to compare the concentration of Cladosporium spores in the cities of Szczecin, Warsaw, Sosnowiec, Olsztyn and Cracow in 2007. Measurements were performed by the volumetric method (Burkard and Lanzoni pollen and spores sampler). Cladosporium season was defined as the period in which 90% of the annual total catch occurred. The Cladosporium season started first in Krakow on the 29th April and in the other cities it started during the next days. The highest airborne concentration of 21 042 Cladosporium spores × m-3 was noted in Szczecin on the 13nd of July

    During the spring period, Betula pollen is the main cause of inhalant allergies in Poland and therefore it is impor- tant to monitor and forecast airborne pollen concentrations of this taxon. This study conducted a comparative analysis of the basic characteristics of Betula pollen seasons at the regional scale. The study was carried out from 2001 to 2016 in fi ve cities in Poland: Lublin, Warsaw, Cracow, Sosnowiec, and Szczecin. To fi nd the attri- butes of birch pollen seasons that mostly differentiated the individual cities, a general discriminant analysis (GDA) was performed, while a principal component analysis (PCA) allowed us to reduce the data space and pres- ent a scatterplot of PCA scores in order to compare pollen seasons in the individual cities. The contingency table was also analyzed to check whether there was a signi fi cant relationship between pollen counts in the studied years and cities. At most of the sites, biennial cycles of low and high pollen concentrations can be observed. Due to the high variation in seasons in each of these cities, two data groups were distinguished: Group 1 was composed of seasons with high pollen deposition (2001, 2003, 2006, 2008, 2010, 2012, 2014, 2016), and Group 2 comprising the other seasons. Multivariate analyses were performed on both these groups as well as in the entire dataset. End98, Peak Value, and Annual Total had the highest discriminant power. In Group 1, Warsaw and Sosnowiec differed the most in the investigated parameters, while Cracow and Szczecin differed the least. In both groups, most seasons with the highest pollen birch concentration were observed in Lublin, followed by Warsaw, while in Cracow, the number of such seasons was the smallest

    This paper presents the course of alder pollination season in Poland in 2020. The measurements were performed in Bydgoszcz, Bialystok, Lublin, Olsztyn, Opole, Piotrkow Trybunalski, Sosnowiec, Szczecin, Warsaw, Wroclaw and Zielona Gora. Volumetric method with the use of Volumetric Spore Trap (Burkard, Lanzoni) was implemented. Pollen season was defined as the period in which 95% of the annual total catch occurred. The alder pollen season in 2020 started about 10–30 days earlier compared to 2017–2019. The pollen season started first in Szczecin, Opole and Zielona Gora (in the second half of January). In the other cities alder pollen season started in first half of February. The highest daily pollen count was recorded in Lublin (1211 P/m3). In other cities the maximum concentrations ranged from 160 P/m3 in Sosnowiec to 465 P/m3 in Piotrkow Trybunalski. The highest alder pollen concentrations were detected in the first decade of March (March 1st–3rd). Only in Zielona Gora, Wroclaw, Opole and Sosnowiec the maximum concentration was recorded in the third decade of February. The annual pollen sum of Alnus in 2020 was even 5–10 times lower than in years 2019

    Celem pracy było porównanie sezonu pyłkowego cisa i jałowca w 2008 r. w Szczecinie, Wrocławiu, Krakowie, Lublinie, Warszawie i Sosnowcu. Pomiary stężenia pyłku prowadzono metodą objętościową z zastosowaniem aparatu Burkard oraz Lanzoni 2000. Sezon pyłkowy wyznaczono jako okres, w którym w powietrzu występuje 95% rocznej sumy ziaren pyłku. Początek sezonu pyłkowego wyznaczono również metodą 30 ziaren. Indeks SPI obliczono jako sumę średnich dobowych stężeń pyłku w danym sezonie. Sezon pyłkowy cisa i jałowca rozpoczął się najwcześniej w Warszawie, 17 lutego, a w pozostałych miastach w ciągu dziesięciu kolejnych dni. Zanotowano znaczne różnice w czasie trwania sezonu. Najwyższe, rekordowe wartości stężeń zaobserwowano w Szczecinie, maksymalne stężenie wynoszące 256 ziaren × m-3 zarejestrowano 27 lutego.The aim of the study was to compare the pollen seasons of yew and juniper in the cities of Szczecin, Wroclaw, Krakow, Lublin, Warszawa and Sosnowiec in 2008. Measurements were performed by the volumetric method (Burkard and Lanzoni 2000 pollen sampler). Pollen season was defined as the period in which 95% of the total annual catch occurred. The start of the season was also determined by the 30 grains method. Seasonal Pollen Index (SPI) was estimated as the annual sum of daily average pollen concentrations. The pollen season of yew and juniper started first in Warsaw on the 17th of February and in the other cities it started during the next ten days. The differences of pollen seasons duration were considerable. The highest, record airborne concentration of 256 pollen grains × m-3 was noted in Szczecin on the 27th of February

    Forecasting model of Corylus, Alnus, and Betula pollen concentration levels using spatiotemporal correlation properties of pollen count

    Get PDF
    The aim of the study was to create and evaluate models for predicting high levels of daily pollen concentration of Corylus, Alnus, and Betula using a spatiotemporal correlation of pollen count. For each taxon, a high pollen count level was established according to the first allergy symptoms during exposure. The dataset was divided into a training set and a test set, using a stratified random split. For each taxon and city, the model was built using a random forest method. Corylus models performed poorly. However, the study revealed the possibility of predicting with substantial accuracy the occurrence of days with high pollen concentrations of Alnus and Betula using past pollen count data from monitoring sites. These results can be used for building (1) simpler models, which require data only from aerobiological monitoring sites, and (2) combined meteorological and aerobiological models for predicting high levels of pollen concentration
