In this present study, airborne pollen in Çeşme was investigated between February 17, 2012 and February 17, 2014 using the volumetric method. Çeşme, one of Turkey's most important tourism centers, which attracts numerous local and foreign tourists each year, is a district of Izmir, a province in the western part of Turkey. During the 2-year study, 12,905 pollen grains belonging to 64 taxa (33 arboreal, 31 non-arboreal plants) were detected. However, the 2-year data results revealed that the taxa with the pollen concentration more than 4% in the atmosphere were Cupressaceae/Taxaceae (4268 pollen, 33.07%), Olea europaea (1614 pollen grains, 12.51%), Pinaceae (1085 pollen grains, 8.41%), Quercus spp. (1081 pollen grains, 8.38%), Pistacia spp. (743 pollen grains, 5.76%), and Poaceae (557 pollen grains, 4.32%), all of which comprised 72.44% of the total count. The relationship between the daily pollen counts belonging to these six taxa and the hourly average temperature (°C), daily precipitation (mm), relative humidity (%), and wind speed (km/h) was assessed using the Spearman correlation test, and significant results were determined. During the study, the intradiurnal distribution of the aforementioned pollen varied. The highest pollen concentration was detected between 11:00 a.m. and 6:00 p.m. (first year 30.3%; second year 30.1%).
IntroductionAllergic diseases affect 20%-30% of Turkish population and constitute an important disease group due to the labor and financial losses they cause (Bıçakçı et al., 2009). In some countries, the rates of diseases causing allergy in humans are as follows: 14% in Finland, 5.9%-
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.
Bu çalışmada zeytin ağaçlarının geniş yayılış gösterdiği Aydın, Manisa ve Muğla atmosferlerindeki Olea europaea L. polenlerinin dağılımları incelenmiştir. Volumetrik yöntem ile 2014-2016 yılları arasında gerçekleştirilen çalışmada bu taksona ait polenlerin yıllık değişimleri ve polen sezonu üzerinde meteorolojik faktörlerin etkisi incelendi. İki yıllık çalışma süresince zeytin polenlerine en fazla rastlanan ilin Aydın olduğu görüldü. Bu şehirde zeytin polenlerinin atmosferde kaydedilen tüm polenlerin %20.92'sini oluşturduğu ve baskın taksonlar içerisinde ilk sırada yer aldığı belirlendi. Bununla beraber, zeytin polenleri Manisa ve Muğla'da sırasıyla %15.55 ve %7.16 ile üçüncü sırada yer aldı. Bu bitkinin polenleri tüm bölgelerde en fazla Mayıs ayında kaydedildi, ancak esas polen dönemlerinin çalışılan iller ve yıllar arasındaki meteorolojik değişimlerin etkisiyle farklılıklar gösterdiği görüldü. Diğer taraftan bu taksona ait günlük polen sayıları, meteorolojik faktörlerle korale edildi ve günlük ortalama sıcaklık (o C), günlük toplam yağış (mm) ve günlük ortalama nisbi nem (%) ile günlük polen sayıları arasında Spearman korelasyon testine göre anlamlı sonuçlar bulundu (p<0.01, p<0.05).
