    (Springer, 2017) Bicakci, Adem; Tosunoglu, Aycan; Altunoglu, Mustafa Kemal; Saatcioglu, Gulsah; Keser, Ali Murat; Ozgokce, Fevzi
    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 FUNGAL SPORES OF NORTH-WEST ANATOLIA
    (Bangladesh Botanical Soc, 2016) Saatcioglu, Gulsaii; Tosunoglu, Aycan; Malyer, Hulusi; Bicakci, Adem
    Fungal spores of north-west Anatolia, Gemlik captured using Durham samplers were investigated. Accordingly 29.916 fungal spores per cm(2) area were counted and 32 taxa were determined in a year. The dominating taxa were; Cladosporium(27.97 %), Basidiomycetes (24.90%), Aspergillus/Penicillum (21.75%), Ustilaginales (10.03%) and Alternaria (3.95).

    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.

    Allergenic Betula (Birch) Pollen Concentrations in Turkey
    (Bilimsel Tip Yayinevi, 2017) Bicakci, Adem; Saatcioglu, Gulsah; Tosunoglu, Aycan
    Objective: Pollen grains belonging to some plants have an important place among aeroallergens that present in the air and cause allergies by entering the body via the respiratory tract. These include Betula (birch - birch tree) pollen belonging to the family of Betulaceae. Materials and Methods: In this study, we reviewed studies on the monthly variation and annual proportions of Betula pollen in 51 different regions in Turkey with the volumetric method using a Lanzoni/Burkard sampler or with the gravimetric method using a Durham sampler together with the daily distribution of Betula pollen in m(3) air in Bursa province in 2012. Furthermore, the authors reviewed studies on Betula pollen sensitivities in Europe and our country. Results: According to the atmospheric pollen studies, Birch tree pollen was found in the air for 3-5 months at many centers. It was most intensely observed in March-April. A total of 454 birch pollens were found in m(3) air in 2012 in Bursa. The birch tree main pollen season lasted 86 days and birch pollen grains were most intensely encountered in March. Conclusion: Symptoms can develop in people who are sensitive to birch tree pollen in the spring due to widespread planting for decorative purposes especially in parks and gardens and along the streets in recent years and the resultant production of large amounts of pollen, especially in April and May. In addition, it must not forgotten that some food allergies of vegetable origin (oral allergy syndrome) can be accompanied by pollen allergy in these individuals.

    Allergenic Platanus (plane tree) pollen concentrations in Turkey
    (Bilimsel Tip Yayinevi, 2015) Bicakci, Adem; Tosunoglu, Aycan; Saatcioglu, Gulsah
    Objective: Plane tree pollen grains has an important place among aeroallergens that present in the air and cause allergy by entering the body via respiratory track. Materials and Methods: In this study, monthly variation and annual proportions of Platanus pollen investigated for 72 atmospheric pollen studies in Turkey, which carried out by using Lanzoni/Burkard sampler with volumetric method or by using Durham sampler with gravimetric method. Furthermore, researches evaluated about Platanus pollen sensitivities, performed in Europe and our country. Results: According to the atmospheric pollen studies, plane tree pollen grains have been detected in a very short period and intensively in the air. In some regions, Platanus pollen found in very highlevels and placed in most dominated five taxa among the total. In Bursa city, main pollen season of plane tree pollen grains continued for 62 days in the year 2013. Conclusion: Due to carrying out widespread planting of Platanus for decorative purposes especially in parks, gardens and along the streets in recent years and producing large amounts of pollen in spring period especially in April and May; it should be considered that symptoms can occur in people who are sensitive to plane tree pollen. In addition it must not forgotten that, vegetable originated food allergy (oral allergy syndrome) can be accompanied with Platanus pollen allergy on these individuals.

    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.
