In 2022, the concentration of airborne Amaranthaceae pollen was investigated in 10 Polish cities: Bialystok, Bydgoszcz, Cracow, Lublin, Olsztyn, Opole, Piotrkow Trybunalski, Szczecin, Warsaw, and Wroclaw. The volumetric method based on the use of Hirst pollen samplers was employed. The pollen season was determined with the 98% method. It was found that the Amaranthaceae pollen season started between June 17th and June 28th and ended between September 8th and September 25th. The maximum daily concentrations of the pollen of this taxon in the air of the examined cities were recorded between July 3rd and August 31st, with the highest values detected in Opole and Piotrkow Trybunalski and the lowest values recorded in Bialystok and Olsztyn. The annual Amaranthaceae pollen sum had highest value in Bydgoszcz and Opole and an over six-fold lower value in Bialystok.
