The aeropalynological investigations conducted across the trans-Gomti region of Lucknow provide a comprehensive understanding of the airborne pollen and fungal spores in an urban environment. Seasonal sampling revealed that arboreal taxa dominated during the summer, while non-arboreal elements, particularly grasses and fungal spores, were more prevalent during the post-monsoon period. The consistent detection of airborne pollen types such as Emblica officinalis, Madhuca indica , Moraceae, Pinus, Syzygium cumini and herbaceous taxa including Poaceae, Chenopodiaceae, Artemisia and Ageratum conyzoides , along with fungal spores, underscores the city’s high aeroallergen load. These findings highlight the significant influence of local vegetation, climatic factors and anthropogenic activities on airborne pollen distribution and concentration. The study establishes an important baseline for understanding the aeroallergen dynamics of Lucknow, which can aid in developing region-specific pollen calendars and allergy forecasting models. This research thus bridges aerobiology, environmental monitoring and public health, contributing valuable data for allergy management and ecological assessment.
