Pollen monitoring, Lodz 2012 – aerobiology in practice
Barbara Majkowska-Wojciechowska, Zofia Balwierz, Marek L. Kowalski

Introduction. Aeroallergens of pollen and mold can exacerbate symptoms
of allergic disease in already affected individuals thus local monitoring
of the pollen counts is helpful for allergy diagnosis and management.
This paper reports detailed results from determinations of airborne
pollen concentrations during a pollen season in Łódź.
Aims. The aim of the study was to analyze trends in the concentrations
for 22 taxa of pollens in 2012.
Methods. Concentrations of 20 pollen taxa (Alnus, Corylus, Carpinus,
Betula, Populus, Fagus, Fraxinus, Quercus, Pinus, Picea, Salix, Juniperus/
Taxus, Acer, Poaceae, Plantago, Rumex, Urtica, Artemisia, Ambrosia, Chenopodiaceae)
and two spores (Cladosporium and Alternaria) were determined
with a volumetric method from March to September 2012.
Results. Our study found very high concentrations of Cladosporium
spores, which persisted throughout all season and totally dominated in
the aeroplankton. The total yearly count of specified pollen and mould
taxa was 1035500. The sum of pollen grains reached 50461, so pollen
grains contributed only 5% of the total count whereas the contribution
of fungal spores was 95%. The total value of tree pollen taxa was about
three times higher than the herbaceous taxa. The highest pollen count of
all pollen tree types was recorded for Betula (2198), followed by Pinaceae
(7713) and Alnus (3961). The prevailing taxa among pollen of herbaceous
plants was Urtica (7672), Poacceae (2463), Artemisia (940). Total concentrations
of more than 10000 grains in 1m3 persisted during 30 days
of the season, and for 2 days the concentration was over 40000 in 1m3.
Grains of ambrosia pollen were present in the aeroplankton of Łódź in
numbers similar to those recorded in 2011 season. Information on pollen
levels in Lodz air, conducted in 10th season by Aeroallergens Monitoring
Centre (AmoC) in Lodz was offered to sensitized patients, physicians and
scientists in the region.
