“…Interestingly, a positive SPT or RAST to pollens or to animal danders was generally less common, which agrees with earlier reports regarding rural workers [11,13]. This feature remains unclear, since pollen counts do not differ between Gotland and the Swedish mainland [32] and most farmers keep cats and dogs. One could speculate that this is due to an early health-related selection of affected individuals, but a study from the Department of Stress Research at the Karolinska Institute, Sweden, has shown that farmers in fact have a lower risk of leaving their occupation than do people in other lines of work [33].…”

“…and also Poaceae were found to be rather frequent. Cosentino et al (1995) and Ekebom et al (1997) found similar results indicating that pollen is rather allergenic. Arboreal pollen grains were higher in number than herb pollen grains with respect to total pollen concentrations (81.0% and 16.8%, respectively).…”

“…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.

“…This was particularly true among the infants without any allergic symptoms during their second year of life. The findings cannot be explained by differences in exposure to cat and birch, as this is comparable in the two countries [14,20]. The cumulative incidence of dermatitis was lower in the Estonian than the Swedish infants during the first 2 years of life.…”
