Extreme events in pollen concentration in Poznań, Poland: seasonality, trends and health impact

Aerobiology studies the biological particles in the air that affect human health, especially plant pollen that causes allergies. The purpose of this study is to describe and examine the pollen seasons of the following plants: plantain (Plantago sp.), mugwort (Artemisia sp.), alder (Alnus sp.), birch (Betula sp.), grasses (Poaceae sp.), and hazel (Corylus sp.) during the period 1996‒2021. The results show that each species experiences unique pollen seasons that are influenced by weather patterns. By comprehending these patterns, pollen thresholds essential for controlling pollen allergies and reducing negative health effects can be established.
