INNOVATIVE METHODS FOR AIR MICROPOLLUTION RESEARCH

Microscopic biological pollution, such as pollen, can have detrimental effects on human health, serving as a primary cause of respiratory allergies and pollinosis. Furthermore, pollen, as a prominent constituent of biological microscopic pollution, may contribute to the dispersion of industrial pollutants due to the accumulation of chemical elements on its surface. This study aims to evaluate the capacity of pollen to adhere to and transport particulate matter, including potential microplastics.

The study encompasses a comprehensive approach, involving multiple aspects of pollen collection. Firstly, pollen samples were obtained directly from plants. Additionally, pollen was collected from various surfaces, representing different environmental contexts. Furthermore, specialized techniques were employed to capture pollen from airflow. Lastly, controlled laboratory conditions were established to simulate pollution of pollen samples. The collected pollen samples were then subjected to analysis using a scanning electron microscope to examine the composition of the pollen wall, detect different chemical elements, and identify the presence of nanometer-sized particles on the pollen surface.

Through this investigation, two distinct types of pollen samples were differentiated: clean and polluted. The analysis of clean pollen samples revealed the presence of chemical elements, including oxygen (O), carbon (C), potassium (K), phosphorus (P), and calcium (Ca), on the surfaces of hazel (Corylus) and alder (Alnus) pollen. It should be noted that the concentration of these elements may vary depending on factors such as plant species and growth conditions. Moreover, hazel pollen (Corylus) exhibited the presence of chemical elements like lead (Pb), zinc (Zn), and tin (Sn), which can be attributed to environmental pollution.

This abstract presents a preliminary overview of the study, with future research planned to expand upon these initial findings. Subsequent investigations will involve the inclusion of additional plant species and rigorous laboratory experiments to further elucidate the variations in pollen wall composition across different plants, while also considering the influence of diverse growth conditions and environmental factors.
