Fatehpur Shāhbāz, a small city nestled in the heart of Bihar, India, occupies a geographically significant position within the fertile Gangetic plains. Located at approximately 25.57° N latitude and 85.34° E longitude, the city’s terrain is predominantly flat, characteristic of the Indo-Gangetic Plain, with an average elevation of around 58 meters above sea level. This low-lying topography contributes to a tendency for pollutants to accumulate, particularly during periods of atmospheric stability. The surrounding landscape is dominated by agricultural fields – primarily rice and wheat cultivation – which, while vital for the regional economy, can contribute to particulate matter pollution through seasonal burning practices. Fatehpur Shāhbāz sits within a transitional zone, exhibiting a gradual urban-rural gradient. While the city itself is relatively small, it serves as a local trading hub for surrounding villages, leading to vehicular traffic and associated emissions. The nearest major river, the Ghaghara (also known as the Saryu), flows some distance away, offering limited influence on local air quality through precipitation or wind patterns. The city’s proximity to industrial clusters in larger Bihar cities, though not immediately adjacent, means that pollutants can be transported via prevailing winds. The flat, expansive nature of the plains allows for long-range transport of pollutants, exacerbating local air quality challenges. The lack of significant topographical features to disrupt airflow further contributes to the potential for stagnant air conditions and pollutant build-up.

Fatehpur Shāhbāz experiences a distinct wet and dry season, significantly impacting its air quality profile. The dry season, typically spanning from October to May, presents the most challenging period. Reduced rainfall, coupled with lower humidity, leads to increased dust levels and a greater propensity for particulate matter to remain suspended in the air. Temperature inversions, common during the colder months (December-February), trap pollutants near the ground, worsening conditions. Agricultural burning, a widespread practice after the harvest season (October-November), releases substantial amounts of smoke and particulate matter, dramatically degrading air quality. The monsoon season (June-September) brings relief, with frequent rainfall washing away pollutants and strong winds dispersing them. However, the onset of the monsoon can initially be accompanied by increased humidity and fog, which can temporarily reduce visibility and trap pollutants. During the summer months (April-May), high temperatures and stagnant air can exacerbate the effects of existing pollution sources. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, particularly during agricultural burning periods. Limiting outdoor exertion and wearing masks can help mitigate exposure. The transitional periods (March-May and September-November) often see fluctuating air quality, influenced by changing wind patterns and temperature variations. Maintaining awareness of local conditions and adhering to public health advisories is crucial for protecting respiratory health throughout the year.
