摘要：Pollen monitoring was carried out in Lublin in 2001–2012 by the volumetric method using a Hirst-type spore trap (LanzoniVPPS 2000). Daily pollen concentrations considerably differed in the particular years. The pollen counts with the biggestvariability were observed in the first half of a year when woody plants flowering. The highest annual pollen index werenoted for the following taxa: Betula, Urtica, Pinaceae, Poaceae and Alnus. Betula annual total showed the greatest diversityin the study years. The number of days on which the pollen concentration exceeded the threshold values, thereby inducingallergies, was determined for the taxa producing the most allergenic pollen. The above-mentioned taxa primarily includedthe following: Poaceae, in the case of which the highest number of days with the risk of occurrence of pollen allergy wasfound (35), Betula (18), and Artemisia (10). The following taxa: Alnus (14 days), Populus (11 days), Fraxinus (10 days), and Quercus(8 days), were also characterized by a large number of days on which their pollen concentrations exceeded the thresholdvalues. The occurrence of periods of high concentration of particular pollen types were also noted. Risk of pollen allergyappeared the earliest at the beginning of February during Alnus and Corylus blooming. High concentrations of other woodyplants were recorded from the last ten days of March to about 20 May, and of herbaceous plants from the first/last half ofMay – beginning of October
