Abstract :Airborne pollen grains in Aydin, an important city for agriculture and tourism in the western part of Turkey, were studied for 2 years insert ignore into journalissuearticles values(2014 and 2015); using the volumetric method. During a 2-year study conducted in the city center, an average of 19,226 pollen grains belonging to 46 taxa were detected. Among these detected taxa, 29 insert ignore into journalissuearticles values(average 73.97%); belonged to arboreal plants and 17 insert ignore into journalissuearticles values(average 24.95%); to nonarboreal plants. The highest pollen concentrations belonged to Olea europaea insert ignore into journalissuearticles values(21.02%);, Quercus insert ignore into journalissuearticles values(15.23%);, Poaceae insert ignore into journalissuearticles values(11.89%);, Pinaceae insert ignore into journalissuearticles values(11.47%);, Cupressaceae/Taxaceae insert ignore into journalissuearticles values(11.11%);, Platanusinsert ignore into journalissuearticles values(4.12%);, Morus insert ignore into journalissuearticles values(3.83%);, and Urticaceae insert ignore into journalissuearticles values(3.58%);, which were considered to be the dominant species. We used the Spearman correlation test to assess the relationship between the daily pollen concentrations belonging to these 8 taxa and the mean average temperature insert ignore into journalissuearticles values(degrees C);, daily precipitation insert ignore into journalissuearticles values(mm);, mean average relative humidity insert ignore into journalissuearticles values(%);, and mean average wind speed insert ignore into journalissuearticles values(m/sec);, which yielded significant results. A negative correlation was found between the average temperature and the pollen concentrations of Poaceae, Pinaceae, Cupressaceae/Taxaceae, Morus, and Urtica in both years. Furthermore, while the average wind speed only had a negative effect on the pollen concentrations of some taxa, the effects of relative humidity and precipitation on the pollen concentrations of dominant taxa varied from one taxon to another and between the 2 years. The results obtained in this study indicated that the top 3 dominant airborne pollen types insert ignore into journalissuearticles values(Olea europaea, Quercus, and Poaceae); in the atmosphere of Aydin generally had allergenic effects at high levels, and the highest pollen concentration during the study period was detected in May.
