The data set for constructing the forecasting model was obtained
using a Hirst volumetric spore-trap situated in the centre
of Poznan for 12 consecutive years (1996– 2007). Start date
of pollen seasons was determinated using several methods
(threshold values, cumulative sum of pollen and the 90, 95 and
95% method). The accuracy of the models was tested by comparing
the predicted values with the real values recorded during
two additional years not included in model (2008– 2009).
Meteorologic data collected during the months before flowering,
including 2-, 3-, 4-, 5-, 6-weeks mean maximum, minimum
and mean temperature and total sum of rainfall were
studied in order to determine their influence on Betula and
Quercus pollen seasons. Additionally, the phenological data,
information about dormancy and heat accumulation period
(heat units) and the role of photoperiod in incuding flowering,
were used during the modelling process. The most important
factor determining the start of the pollen season was mean daily
maximum temperature recorded one month before flowering.
Based on this factor, the prediction was accurate to within
a few days. Similar results were obtained using heat units. The
main factors responsible for the intensity of flowering were the
sum of the rain during summer one year before flowering, the
pollen production in the previous year and the amount of rain
in the weeks before flowering.

Aerobiological monitoring was performed in 10 cities in Poland
in 2009. The Corylus pollen seasons were clearly skew to
the right. A very quick increase in pollen concentration in the
air and a clearly slower decline were observed. In Poznań and
Olsztyn the pollen seasons were the shortest, somewhat over
1 month. In Sosnowiec pollen occurred in the air for over 100
days. In Cracow and Sosnowiec dynamics of the pollen seasons
were the most similar. In Rzeszów and Lublin the pollen seasons
were clearly different from seasons in other cities. The pollen
seasons started the earliest in Lublin and Rzeszów (7 Feb),
30 days later in Bydgoszcz. The last pollen grains in Olsztyn
were noted 29 March, in Łódź and Lublin 27 April. In Szczecin
maximum concentration value was noted on a day when
in Bydgoszcz the pollen season had just started. In Rzeszów
maximum concentration occurred on a day when in Olsztyn the
pollen season was already over. Such differences result, from
among other differences, from a climatic diversity along a NW-
SE transect in Poland. The strongest variability, referred to daily
pollen concentration values and annual totals. The highest num-
16
ber of pollen grains in a year was stated in Olsztyn, the lowest
in Gdańsk.

The mathematical model for the daily pollen concentration in
the pollen season was performed. The model was calculated
on the grounds that, the daily pollen concentration in the air is
a result of two opposite processes: the pollen concentration increase
caused by pollen release and the decrease caused by the
pollen disintegration. It was assumed that the pollen release
distribution is the normal distribution and the rate of disintegration
is the constant function (independent of time). The
model was tested during the birch pollen seasons in selected
cities (Cracow 1991– 2009, Szczecin 2003– 2009, Rzeszów
1997– 2005, Poznań 1996– 2009, Lublin 2001– 2009, Sosnowiec
1997– 2009). Four season parameters were tested: annual
pollen total, the day of the maximum concentration, standard
deviation of the pollen release distribution and the mean daily
rate of disintegration. Two types of models were presented:
one and two-peaked models depending on the number of
clearly distinguished peak days. In the case of the two-peaked
model it was assumed, that the pollen release is presented by
two normal distributions. For each city, there were more years
with one peak value. The strength of the model fitting data depends
on the outlier points and the daily pollen concentration
fluctuation (the frequency of their occurrence and absolute differences).

Birch pollen contains allergens showing strong allergenic activity
which are a frequent cause of pollen allergy in Europe.
The pattern of birch pollen seasons in Lublin in the period
2001– 2009 was analysed. Pollen monitoring was conducted by
the volumetric method using a Lanzoni VPPS 2000 sampler.
The start of the season, determined using the 98% method,
took place between 3 April and 22 April, while the end between
6 May and 21 May. The highest pollen counts over the
9-year study period were recorded in the second half of April.
Very large variations, related to maximum daily counts and
annual pollen sums in particular years. The shortest season
with intense dynamics was recorded in 2003. The value of the
maximum pollen count in this year was 25 times higher than
in 2009 in which the pollen count was the lowest. It was found
that mean air temperature and rainfall had the greatest effect
on the birch pollen season. The highest negative correlation
was noted between the start of the season and mean temperature
in February. Higher temperature in February promoted
the earlier onset of the season. Maximum pollen counts and
annual pollen sums were correlated with mean temperature in
May of the year preceding pollen release as well as in February
and April in the year of pollen release. Rainfall events in
April significantly delayed the occurrence of maximum birch
pollen counts.
