Bardīha Turki, nestled in the state of Bihar, India, occupies a geographically significant position within the fertile Gangetic plains. Located at approximately 25.8059° N, 85.5441° E, the town’s terrain is predominantly flat, characteristic of the Indo-Gangetic alluvial plain, resulting in minimal elevation changes. This flatness, while conducive to agriculture, also presents challenges regarding air quality dispersion. Bardīha lies within a region heavily reliant on agriculture, with surrounding landscapes dominated by rice paddies and other cultivated fields. The proximity to the Ganges River, though providing a vital water source, can also contribute to humidity and stagnant air conditions, particularly during certain times of the year, hindering pollutant dispersal. The urban–rural gradient around Bardīha is gradual, with small villages and agricultural land seamlessly blending into the town's periphery. While Bardīha itself is a relatively small settlement, it’s situated within a broader agricultural belt, and the burning of crop residue after harvest – a common practice in the region – significantly impacts local air quality. Furthermore, the town’s connectivity to larger urban centers in Bihar, via road networks, introduces vehicular emissions as a contributing factor. The lack of significant topographical features limits natural ventilation, potentially trapping pollutants and exacerbating air quality issues. The flat terrain and surrounding agricultural landscape create a unique microclimate that influences how pollutants behave and spread within and around Bardīha.

Bardīha Turki experiences a distinct seasonal pattern influencing its air quality. The dry season, typically spanning from October to May, presents the most significant air quality challenges. During these months, lower humidity and reduced rainfall contribute to stagnant air conditions, trapping pollutants. Temperature inversions, common during the colder nights of November to February, further exacerbate this issue, preventing vertical mixing and concentrating pollutants near the ground. The burning of crop residue following the harvest season (October-November) is a major episodic event, releasing substantial quantities of particulate matter and other harmful gases. The monsoon season (June to September) brings relief, with increased rainfall and wind speeds naturally dispersing pollutants. However, even during the monsoon, humidity can be high, and periods of calm can still lead to localized pollution build-up. The pre-monsoon period (March-May) often sees a gradual increase in pollution levels as temperatures rise and the wind speeds decrease. The summer months (April-May) are generally hot and dry, with occasional dust storms further degrading air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly during periods of crop residue burning. Limiting outdoor activity during peak pollution episodes and wearing appropriate masks are recommended. The transition periods, spring and autumn, offer relatively better air quality, making them more favourable for outdoor activities.
