“…They found no significant IgE level change between unpolluted and polluted pollen immunized animals. When comparing Pinus eldarica pollen material exposed in polluted Tehran zones versus fresh gathered unpolluted pollen, the same team found higher eosinophilia (14% more) for guinea pigs injected with polluted material [ 219 ]. On pollen from herbs, results of Madj's team on Tagetes patula and Spartium junceum pollen material showed higher values of eosinophils, neutrophils, and IgE for animals injected with extracts prepared from polluted pollen [ 218 ].…”

This review summarizes the available data related to the effects of air pollution on pollen grains from different plant species. Several studies carried out either on in situ harvested pollen or on pollen exposed in different places more or less polluted are presented and discussed. The different experimental procedures used to monitor the impact of pollution on pollen grains and on various produced external or internal subparticles are listed. Physicochemical and biological effects of artificial pollution (gaseous and particulate) on pollen from different plants, in different laboratory conditions, are considered. The effects of polluted pollen grains, subparticles, and derived aeroallergens in animal models, in in vitro cell culture, on healthy human and allergic patients are described. Combined effects of atmospheric pollutants and pollen grains-derived biological material on allergic population are specifically discussed. Within the notion of “polluen,” some methodological biases are underlined and research tracks in this field are proposed.

“…Many people suffer from allergic diseases and much research has illustrated that pollen can play an important role in inducing such diseases. The fact that allergic symptoms are more prevalent in larger cities may be related to the increase in air pollution attributable to mineral or synthetic materials released into the atmosphere by cars and factories (Majd and Ghanati 1995;Nowak et al 1996;Ekebom et al 1997;Puc and Puc 2004). Although groves, farms and arboreals are more often found in villages and the suburbs, the intensity of pollen allergies is higher in urban centres, in industrial cities in particular.…”

The aim was to investigate the impact of atmospheric pollen in determining allergic rhinitis. It was conducted with 130 patients with allergic rhinitis in three different sites in Eskisehir, Turkey, in 2000-2001, using a gravimetric method with a Durham sampler. Skin prick test results, the symptoms of patients and their findings all confirmed the presence of allergic reactions to pollen allergens in the patients observed. During the period, a total of 47,082 pollen grains/cm(2) belonging to 45 taxa were recorded. Of the total pollen grains, 81.0% were arboreal and 18% non-arboreal. The majority of the investigated pollen grains were from Pinaceae, Salix spp., Chenopodiaceae/Amaranthaceae, Cupressaceae and Poaceae. Pollen concentrations reached the highest level in May (54.36%). The pollen allergens provoking severe sensitization were grasscereal mixtures (58.5%), followed by arboreals (33.8%). All patients (100.0%) were sensitive to grass. This study emphasizes the significance of determining the types and concentrations of pollen with a view to comparing changes in highly concentrated allergens.

“…Pollen, also known as flower pollen, is composed of protein substances that facilitate the reproduction of flowering plants. Pollen grains are so small that thousands of them can be found in a single speck of pollen, and they can be easily carried to distant places by the wind (Majad and Ghanati, 1995;Potoğlu Erkara, 2005).…”

In this study, the pollen morphology of the allergic Dysphania botrys (L.) Mosyakin & Clemants (Amaranthaceae) taxon, which has a natural distribution within the borders of Eskişehir province, was investigated in terms of pollen morphology and allergic properties. Pollen grains of D. botrys are periporatae and sphaeroidal shaped. As a result of microscopic examinations, A/B=1.06 μm (W), A (polar axis): 4.08 µm; B (Equatorial axis): measured at 25.04 μm. The thickness of the Exine is 1.73 µm.
