Introduction. Pollen allergy prevalence, especially in the inhabitants
of big urban aglomerations, causes the increased interest in pollen
and fungal spores concentrations in the atmosphere.
Aim of study. The aim of the study was to present the concentrations
of twenty selected pollen taxons of aeroplankton in the atmosphere
of Lodz in 2009.
Material and methods. Pollen grains were counted weekly, with the
use of 7-day volumetric spore-trap located in the centre of Lodz.
Results. During the vegetation period of 2009 the mould spores Alternaria
and Cladosporium dominated, followed by tree pollen and
herbaceous plant taxons. During the analysed season, pollen grains
of the hazel taxon appeared in the air as the first ones on 3 March.
The season of birch pollen started on 2 April and ended on 22 May.
These pollen grains were present in the air for 50 days. The highest
total numbers of the analysed tree taxons were recorded for: pine
family (Pinaceae), birch (Betula), oak (Quercus), alder (Alnus). Among
the herbaceous plants, the nettle (Urtica) pollen grains dominated,
followed by grass pollen (Poaceae/Cerealia), mugwort (Artemisia)
and sorrel (Rumex). The grass pollen appeared at the begining of
May and was present in aeroplankton until the middle September.
The longest period of pollen presence in the air was recorded for
Platango pollen grains (noted for 144 days). Among the herbaceous
plants, the Ambrosia pollen was present in the air from 8 to 21 August.
The total yearly count of tree pollen was lower than in the same
season in 2008, but the total number of pollen grains of herbaceous
plants reached a higher level.
Conlusion: The test results obtained in Lodz in 2009 do not indicate
any significant increase of aeroplankton concentrations in 2009 or
enlengthened blossom season of the plants of allergenic importance
(observed in Western countries) that could indicate the effects of
climate warming in central Poland.
