The aim of the study was to compare pollen season of mugwort in Bialystok, Bydgoszcz, Drawsko Pomorskie, Olsztyn, Piotrkow Trybunalski, Szczecin and Warsaw. Measurements of pollen concentrations were performed with the volumetric method; Burkard or Lanzoni pollen sampler. The pollen season of mugwort started first in Bialystok (on the 8th of July). Maximum pollen concentrations were observed in all measurement sites in the period between 7th August and 18th August. The highest concentration of mugwort pollen and the highest annual sum of pollen grains concentrations in the air were recorded in Bydgoszcz, Drawsko Pomorskie and Olsztyn.
