This research is an aeropalinological study conducted in Trabzon, determining polinization period of the plants in designated locations, creating the pollen calendar of 2005 and assisting physicians in the diagnosis and treatment of allergic diseases caused by the pollen of these plants. Pollens in Trabzon atmosphere were collected daily between 01 February 2005 and 30 January 2006 using the Durham device, which is the application tool of the gravimetric method. In the study area, 22 565 (excluding unidentified pollen) pollen from 33 taxa, including 19 trees and shrubs and 14 herbaceous plants, were recorded. 30 taxa were detected in both stations. Total pollen percentages of 14 taxa with more than 1% total pollen count; Betulaceae (21,49), Poaceae (14,16), Corylus (8,16), Legüminosae (7,31), Alnus (7,17), Pinaceae (6,44), Cupressaceae (5,42), Oleaceae (5,37), Artemisia (4,23), Carpinus (3,83), Compositae (2,48), Ambrosia (2,27), Amaranthaceae (1,71), Urticaceae ( 1,32). Although the richest month in taxon diversity was 17 taxa in April, 31.13% of the total number of pollen was recorded during the month of February when woody pollen was dense. The increase in the temperature, wind speed and relative humidity rates have affected the amount of pollens positively and also effected the precipitation negatively.
