Main Article Content
Abstract
The course of hazel, alder and birch pollen seasons in Warsaw in year 2014 is presented. Measurements were performed by the volumetric method (Lanzoni pollen sampler). Pollen season was defined as the period in which 98% of the annual total catch occurred. The peak of hazel pollen season was recorded in the 2nd decade of February. The peak of alder pollen season in 2014 in Warsaw was recorded in the 3rd decade of February and 1st decade of March. The presence of birch pollen was noted in Warsaw in the 1st decade of April, with the pollen count reaching 1200–2400 grains/m3. The highest daily birch pollen concentration amounting to 2437 birch grains per m3 of air was found April 8. Seasonal Pollen Index of birch reached 21 002.
