Abstract
Aim: to examine the content of plant pollen and fungal spores in the air of Karakol city (Kyrgyz Republic) during the seasons from 2015 to 2017. Materials and Methods: in the course of the aerobiological study, samples containing bioparticles (plant pollen and fungal spores) were collected from the air. The samples were identified to the genus or family level, or, in some cases, to the species level, and quantified by visual counting in the field of view of a microscope. A Lanzoni volumetric pollen and spore trap was placed on the roof of a building within the city borders (Karakol) at a height of 13 m above ground level, away from park areas and industrial enterprises. A total of 630 atmospheric air samples were collected from April to September in 2015-2017. Results: the taxa Artemisia spp., Poaceae, Chenopodiaceae, and Pinus spp. exhibited the greatest abundance in the aerobiological spectrum of Karakol. Among the fungi, Alternaria, Cladosporium, and Fusarium were the most prevalent. The majority of fungal spores (60–76%) were observed during the period from June to August. The absolute maximum of pollen in the air coincided with high temperature values in the area. The highest concentrations of Artemisia pollen were observed from mid to late July, which corresponded to an increase in the average daily air temperature over the study seasons. The highest Artemisia pollen content in the air (61–72%) for the study seasons was observed in Karakol at air temperatures ranging from 28.3 to 33.4°C. High temperatures contribute to the release of spores into the atmosphere. It can be observed that allergenic species of fungi are accumulated in urban environments rather than in natural areas. Conclusion: the quantitative and qualitative profile of pollen from the dominant species of allergenic plants and fungal spores in the air environment of Karakol city was determined in order to contribute to the study of the aerobiological situation. It is important to determine the impact of meteorological factors on the concentration of plant pollen and fungal spores. This will allow for the prediction of the behavior of aeroallergens in a changing climate.
