Abstract

Introduction: Recent epidemiologic studies showed the complex and multifactorial relation between pollinosis augmentation and atmospheric pollution. Pollutants have a direct impact on the physiology of pollens, as well as indirect impact on its ontogenesis via their effect on the producing plants.Objective: This research tries to measure the effects of air pollutants on the pollen structure of the Cupressus arizonica planted in the highest polluted areas of Tehran and its probable influence on the augmentation of pollen allergenicity.Materials and Methods: Pollen samples were collected from C.arizonica trees planted in the high traffic areas of Tehran and also in non-polluted in the suburbs. Scanning electron microscopy was used to examine and compare shapes and strucures of non-polluted and polluted pollens. The existence and percentage of different pollutant elements in pollen tectums were determined and compared via spectrometric analysis.Results and Conclusion: Our microscopic examinations showed that air pollution considerably improved the fragility of pollen exine, causing numerous cracks in its surface and facilitating pollen content liberation. Spectrometric analysis showed the abundant presence of S (37%) on polluted pollen surfaces, which is one of the most irritating elements and may increase the allergenic potency of pollens. On the other hand, this observation reflected the fact that important effects of air pollution on C.arizonica allergenic pollens increase the production of micronic and submicronic aerosols which may have a negative repercussion on the health of urban population.
