The analysis of birch pollen count in selected Polish cities in 2009
Journal Title: Alergoprofil - Year 2009, Vol 5, Issue 2
Abstract
In the present study, birch pollen season patterns in Poland in 2009 have been compared. Airborne pollen counts were made in Białystok, Bydgoszcz, Kraków, Lublin, Olsztyn, Sosnowiec, Szczecin, Warsaw and Wrocław. The investigations were performed using the volumetric method as well as the Burkard and Lanzoni traps. The pollen season duration was determined using the method of 98%. It has been shown that the birch pollen season started in 2009 in the first decade of April, similarly to the years 2007 and 2008. Significant differences were found in pollen season duration between particular cities and in diurnal pollen grain counts. The highest diurnal birch pollen count was recorded in Wrocław (1317 grains/m3) and Szczecin (1166 grains/m3). In all the cities, a large number of days was recorded with a concentration exceeding the threshold concentration for birch (17–29 days).
