Koriāpatti, nestled in the fertile plains of Bihar, India, occupies a geographically significant position within the Gangetic Basin. Located at approximately 26.1149° N, 86.9905° E, the town’s terrain is predominantly flat, characteristic of the Indo-Gangetic Plain, with an elevation of roughly 128 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 to the regional economy, can contribute to particulate matter through seasonal burning practices. Koriāpatti’s proximity to the Ganges River, though not directly adjacent, influences regional humidity and weather patterns, impacting pollutant dispersion. The urban–rural gradient around Koriāpatti is gradual; the town itself represents a small urban centre surrounded by a predominantly agrarian landscape. While not situated within a major industrial belt, the town’s connectivity to larger regional hubs via road networks means it is susceptible to transboundary pollution. The flat, expansive terrain limits natural ventilation, and the lack of significant topographical features hinders the effective dispersal of pollutants released from agricultural activities and occasional vehicular traffic. The soil composition, largely alluvial, can also influence the suspension of fine particulate matter during dry periods, further impacting local air quality. The regional climate, characterized by hot summers and a distinct monsoon season, plays a crucial role in shaping the town’s atmospheric conditions.

Koriāpatti’s air quality experiences a distinct seasonal cycle heavily influenced by the monsoon and agricultural practices. The pre-monsoon months (March-May) typically see the poorest air quality, driven by rising temperatures, stagnant air, and the widespread burning of crop residue after the winter harvest. This practice releases significant quantities of particulate matter, creating hazy conditions and impacting visibility. The monsoon season (June-September) brings a welcome respite, as increased rainfall and stronger winds effectively flush out pollutants, leading to a noticeable improvement in air quality. However, periods of heavy rainfall can also lead to localised flooding, potentially releasing pollutants from stagnant water sources. The post-monsoon season (October-November) witnesses a gradual deterioration as temperatures begin to drop and wind speeds decrease, creating conditions conducive to pollutant accumulation. Fog, common during this period, traps pollutants near the ground, exacerbating the issue. Winter months (December-February) are generally cooler, but persistent fog and temperature inversions can lead to periods of poor air quality, particularly in the early morning hours. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the pre-monsoon and post-monsoon seasons, limiting outdoor activity during peak pollution periods. During the monsoon, while overall air quality improves, individuals with allergies should be mindful of increased pollen counts and potential fungal spores. Maintaining indoor air quality through ventilation and air purification can be beneficial throughout the year, especially during periods of elevated pollution.
