This paper presents the course of goosefoot pollination in selected cities of Poland in 2018. The measurements were performed in Bialystok, Bydgoszcz, Cracow, Drawsko Pomorskie, Lublin, Olsztyn, Opole, Piotrkow Trybunalski, Sosnowiec, Szczecin, Warsaw, Wroclaw, and Zielona Gora. Volumetric method with the use of Volumetric Spore Trap (Burkard, Lanzoni) was implemented. In the studied cities in 2018, pollen season of goosefoot started in the third decade of May and ended in the third decade of September. Goosefoot pollen stayed in the air for more than 100 days – 142 days in Sosnowiec and 109 days in Bialystok. Maximum daily concentration (26 P/m3) was noticed in Bialystok, although the lowest – in Cracow (7 P/m3). In the majority of the measuring points the highest moment of pollen season was in August. The highest number of pollen grains in 2018 was found in Lublin (478 grains), the lowest – in Cracow (149 grains). The concentration above 10 P/m3 was very rare, only in Lublin it was this high for 12 days and in Warsaw for 8 days.
