    Pollen concentrations in the atmosphere of Van city has been monitored for two consecutive years (2010-2011). This was the first detailed aeropalynological study for the elevated East Anatolia Region of Turkey. The sampling was performed by Hirst-type volumetric sampler, and pollen grains of 35 taxa were identified. The main pollen producers of the pollen flora were recorded as: Poaceae (20.94 %), Cupressaceae (10.53 %), Fraxinus (8.56 %), Chenopodiaceae/Amaranthaceae (7.77 %), Populus (7.75 %), Quercus (6.70 %), Platanus (6.68 %), Morus (5.57 %), Plantago (3.03 %). The pollen spectrum reflected the floristic diversity of the region, and the highest pollen concentration was recorded in April. There were a great percentage of allergenic taxa found in the city atmosphere, otherwise many of them scored under threshold values for risk of pollinosis. Statistical analyses were performed for correlating daily pollen concentrations of dominated pollen types concurrent with the data of meteorological parameters in MPS periods and number of significant correlations found. In addition, comparing 2-year data in terms of pollen concentrations and meteorological factors in MPS durations, many variables were found explanatory and concordant with the data. MPS starting dates of many plant taxa were found nearly a month later compared with western sites and lower altitudes of the country as well as Mediterranean countries; this case is mostly thought the ecological factors of the study area which directly affects the plant growth about the timing.

    Airborne Populus (poplar) and Salix (willow) pollen grains belonging to Salicaceae family in Turkey
    (Bilimsel Tip Yayinevi, 2014) Bicakci, Adem; Tosunoglu, Aycan; Altunoglu, Mustafa Kemal; Saatioglu, Gulsah
    Introduction: White hairy seeds (cottony tufts) which are spreading to the air from poplar and willow trees, are mostly supposed to be a pollen grain by many people and there is a misconception that consisting allergenic symptoms thought to be due to these seeds. Whereas the air dispersed fluffy structures occur on female poplar and willow trees that are not producing any pollen. In this term, when the seeds of poplar and willow trees matured and dispersed, there are not any pollen grains of these plants in the atmosphere. The pollen grains belonging to both taxa have especially seen in the spring term and they cause sensitization in varying proportions on many individuals suffering from seasonal rhinitis and/or asthma. Materials and Methods: In this study, monthly changes and frequencies of pollen grains belonging to Populus (poplar) and Salix (willow) genera, belonging to Salicaceae family, from 62 airborne pollen studies carried out in Turkey, which prepared both volumetric method by using Lanzoni/Burkard samplers and gravimetric method by using Durham samplers, and studies on pollen sensitivities for both taxa are evaluated. Also daily distributions of poplar and willow pollen grains were investigated in Bursa city in the year 2013. Results: In many regions that airborne studies performed, pollen grains of poplar tree found in the air especially in march-april term and the pollen grains of willow tree in april-may term. In Bursa city, main pollen season of poplar tree found between 27 February-26 April and for willow tree it was between 25 March-28 April. Conclusion: In many regions that atmospheric studies undertaken both of poplar and willow tree pollen grains founded in low levels. Also pollen amounts of both taxa determined in the air of Bursa were low as in the other regions.

    Atmospheric pollen concentrations in Antalya, South Turkey
    (Springer, 2015) Tosunoglu, Aycan; Altunoglu, Mustafa Kemal; Bicakci, Adem; Kilic, Ozkan; Gonca, Taner; Yilmazer, Ilkay; Saatcioglu, Gulsah
    Airborne pollen distribution in Antalya was measured volumetrically during 2 consecutive years, 2008 and 2009. A total of 30,497 pollen grains/m(3) belonging to 44 taxa were recorded annually during the study period. Among the taxa recorded, 27 belonged to arboreal (88.29 %) and 17 to non-arboreal taxa (11.53 %). Seven plant taxa taken as predominant pollen types with the greatest influence in the atmosphere, Cupressaceae/Taxaceae (38.33 %), Pinus (24.18 %), Olea europaea (6.86 %), Morus (5.17 %), Poaceae (4.88 %), Platanus (4.66 %) and Quercus (4.58 %), showed maximum pollen distribution in the atmosphere. The season of maximum pollen concentration was from February to May, with a high prevalence of arboreal pollen grains.
