Aeropalynological Profile Of Cherepovets And Vologda, The Cities Of Vologda Region, Nw Russia

Abstract

The article presents data on the composition and seasonal dynamics of airborne pollen in Cherepovets and Vologda. The study was carried out from April 10 to September 30, 2014 and from April 16 to August 31, 2015 in Cherepovets, and from June 3 to September 30, 2019 in Vologda. Pollen data were obtained from the Durham gravimetric samplers. Samples were collected daily. Twenty-one types of pollen have been identified, ten of which are the most common allergenic types (Alnus, Artemisia, Betula, Fraxinus, Salix, Plantago, Poaceae, Quercus, Rumex, Urtica), which account for more than 50% of all pollen that has been registered. The article contains pollen calendars showing two peaks of pollen grain quantity: spring (from last decade of April to May), summer (from the end of June to the middle of July). Betula (30%) and Asteraceae (28%) pollen dominate in the pollen spectrum. Pinus (20%), Plantago (6%) and Poaceae (5%) also play an important role in the regional spectrum. The results show the presence of allergenic pollen from different taxa throughout the study. The proportion of damaged pollen grains is approximately 2%, which corresponds to the norm in natural population in normal condition. This data can become the basis for developing recommendations for reducing the level of pollinosis in the Vologda Region.
