Aeropalynological survey in the city center of Aydın (Turkey)

Abstract

Airborne pollen grains in Aydın, an important city for agriculture and tourism in the western part of Turkey, were studied for 2 years (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 (average 73.97%) belonged to arboreal plants and 17 (average 24.95%) to nonarboreal plants. The highest pollen concentrations belonged to Olea europaea (21.02%), Quercus (15.23%), Poaceae (11.89%), Pinaceae (11.47%), Cupressaceae/Taxaceae (11.11%), Platanus(4.12%), Morus (3.83%), and Urticaceae (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 (°C), daily precipitation (mm), mean average relative humidity (%), and mean average wind speed (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 (Olea europaea, Quercus, and Poaceae) in the atmosphere of Aydın generally had allergenic effects at high levels, and the highest pollen concentration during the study period was detected in May.

Zeytin Verim Tahmininde Kullanılan Sayısal Modellere İlişkin Bir Literatür Araştırması

“…Bishan et al (2020) published the pollen concentrations in Zhanjiang, South China, and reported the correlation among pollen measurements with several factors, including temperature and relative humidity. Similarly, there have been publications reporting pollen measurements in various regions of Turkey such as Aydın, Muğla, Manisa, (Ulaş and Güvensen, 2019;Güvensen et al, 2020), İstanbul (Celenk et al, 2010) and Antalya (Tosunoglu et al, 2015). Olea was among the species that were examined in those publications.…”

İzmir Polen Alerji Bülteni Karar Destek Sisteminin Kullanıcılar Üzerindeki Etkisinin Değerlendirilmesi

“…Polenler "Alerjik Bünyeli" insanlarda alerjik hastalıklara neden olabilmektedir (3). Polen alerjisinin görülme sıklığı ve etyolojisi bölgeler arasında değişmekte olup İzmir gibi polenden zengin Ege ve Akdeniz coğrafi bölgelerinde sıklığının %20'lere kadar yükseldiği tahmin edilmektedir (4,5).…”

Sinop (Türkiye) Atmosferine Yönelik İlk Aeropalinolojik Araştırma

“…If the types and concentration of the airborne pollen grain in the atmosphere are determined during periods when the symptoms of allergic diseases begin, intensify and end, better results may be obtained in diagnosis and treatment of pollen allergy. As in developed countries, the presence and concentration of allergen pollen grain in the atmosphere in many regions of Turkey has been analysed by using gravimetric and volumetric methods (Aytuğ et al, 1971;Potoğlu Erkara et al, 2007;Kızılpınar et al, 2012;Çeter et al, 2012;Öztürk et al, 2013;Çetin et al, 2015;Türkmen et al, 2018, Alan et al 2018aÖzler, 2019Özler, , Kılıç et al, 2019Alan et al, 2020;Güvensen et al, 2020, Çakır & Doğan, 2020.…”
