Influence of Environmental Pollutants at the Pollen of Poaceae

Abstract

More than 12,000 species belong to the Poaceae family globally; 300 species grow in Kyrgyzstan, anemophilous and releasing a huge amount of pollen into the atmosphere. Poaceae pollen is currently considered the leading airborne biological pollutant (PM10) and the leading cause of pollen allergy worldwide. She is one of the top global aeroallergens. Poaceae pollen has common features: small size, homogeneous morphology, high pollen production and abundance of species. The aim of this work was to study the effect of environmental pollutants on the pollen of Poaceae plants, the classification of identified teratomorphoses and assessment of their specific contribution to the aerobiological situation. The study of Poaceae pollen from various observation points of Kyrgyzstan using scanning electron microscopy revealed teratomorphoses of varying degrees of complexity: 1) deformation; 2) perforation; 3) fragmentation; 4) complex changes in the sculptural elements of the exine surface; 5) combined teratomorphosis, including several types with the transformation of one modification into another. This article summarizes the results of studies reflecting the effects of environmental pollutants on Poaceae pollen, and ultimately on the severity of symptoms and the prevalence of pollinosis.
