摘要：Introduction and objective. The timings of Fraxinus and Betula flowering and pollen release overlap, which may cause
increased allergic reactions in sensitive people. The aim of the present study was to characterize Fraxinus pollen seasons
in Lublin (central-eastern Poland) and to identify meteorological factors that most determine the occurrence of airborne
pollen of this taxon, as well as obtain forecast models for the basic characteristics of the pollen season.
Materials and method. The study was conducted in Lublin during the period 2001–2016, employing the volumetric method.
The seasons were compared by PCA (Principal Component Analysis). To determine relationships between meteorological
conditions and the pattern of pollen seasons, regression analysis was used. Data for the period 2001–2015 were used to
create forecast models by applying regression analysis, while the 2016 data served to verify these models.
Results. Season end date and seasonal peak date were characterized by the lowest variation. The biggest differences were
found for peak value and total annual pollen sum. The average dates of occurrence of ash pollen grains in the air of Lublin
were between 13 April 13 – 3 May 3, whereas, on average, the pollen peak date occurred on 23 April. The factor loading
values for the PC1 variable indicate that it is most strongly correlated with peak value and total pollen sum, while the PC2
variable correlated with the pollen season start date and season duration (a negative correlation). Regression models were
developed for the following pollen season characteristics: season start, end and duration, seasonal peak date, and total
annual pollen sum.
Conclusions. The fit of the forecast models was at the level of 62–94%. Analysis of the data showed that weather conditions
mainly in February were important factors controlling the Fraxinus pollen season.
