In this study, airborne pollen grains of Trabzon were investigated using a volumetric trap VPSS 2000 (Lanzoni) from 01st January 2016 to 31st December 2016. During one-year study period, a total of 29150 polen m-3 belonging to 45 taxa were recorded. From identified taxa, 24 belong to arboreal (69.78%) and 21 taxa to non-arboreal (30.00%) and unidentified pollen grains (0.23%). In the investigated area, from arboreal plant taxa Alnus sp. (23.06%), Cupressaceae-Taxaceae (19.29%), Pinaceae (11.59%), Betula sp. (5.91%), Platanus sp. (3.38%), Quercus sp. (1.67%), Ulmus sp. (1.16%), Fraxinus sp. (1.05%) and from non-arboreal plant taxa Poaceae (13.56%), Urticaceae (7.10%), Boraginaceae (2.12%), Rumex sp. (1.92%), Mercurialis sp. (1.36%), and Artemisia sp. (1.25%) were responsible for the greatest amounts of pollen grains during the study period. The maximum pollen concentration of investigated area is recorded in February (38.39%), March (11.88%) and April (15.67%).
