Khirpai, nestled in the Purba Bardhaman district of West Bengal, India (22.7000° N, 87.6200° E), occupies a geographically significant position within the Ganges Delta region. The city’s terrain is predominantly flat, characteristic of the fertile alluvial plains formed by the Hooghly River, a major distributary of the Ganges. This low-lying landscape, averaging around 12 meters above sea level, contributes to a tendency for pollutants to accumulate, particularly during periods of stagnant air. Khirpai’s location is surrounded by a mosaic of agricultural land, primarily rice paddies and jute fields, which, while vital to the regional economy, can contribute to seasonal particulate matter through agricultural burning practices. The proximity to the Hooghly River, though providing a water source, also influences local humidity and can impact atmospheric stability, sometimes exacerbating pollution episodes. The urban–rural gradient around Khirpai is gradual; the city itself is relatively small, transitioning quickly into agricultural landscapes. Further afield, towards Burdwan and beyond, lie larger industrial zones and urban centers, potentially impacting Khirpai’s air quality through long-range transport of pollutants. The flat topography and deltaic setting limit natural ventilation, hindering the dispersion of emissions from local sources like brick kilns and vehicular traffic. The surrounding landscape, dominated by agricultural fields and scattered villages, creates a unique microclimate susceptible to temperature inversions, especially during cooler months, trapping pollutants close to the ground. This combination of factors makes Khirpai’s air quality particularly sensitive to local and regional emission sources.

Khirpai’s air quality experiences a distinct seasonal cycle heavily influenced by the monsoon climate of West Bengal. The monsoon season, typically spanning June to September, brings relief from accumulated pollutants due to frequent rainfall and strong winds that effectively flush the atmosphere. Humidity levels are high, which can slightly reduce the impact of particulate matter on respiratory health, though it can exacerbate mold and allergen issues. The pre-monsoon months (March-May) often witness a concerning rise in air pollution. Hot, dry winds and temperature inversions become prevalent, trapping emissions from agricultural burning (stubble clearing after the winter harvest) and local industries. This period is generally the most challenging for air quality. The post-monsoon season (October-November) sees a gradual improvement as rainfall decreases, but lingering agricultural burning can still contribute to elevated particulate levels. Winter months (December-February) are characterized by cooler temperatures and frequently dense fog, which significantly reduces visibility and traps pollutants near the ground. The lack of wind during foggy periods leads to a build-up of pollutants. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit outdoor activity during these periods, particularly in the mornings. During the pre-monsoon and winter months, wearing N95 masks can offer some protection. Maintaining indoor air quality through ventilation and air purifiers is also advisable. The monsoon provides a natural cleansing effect, making it the most favourable time for outdoor activities, although high humidity should still be considered for those with sensitivities.
