Shāhkot, a small town nestled in the fertile plains of Punjab, India, occupies a geographically significant position within the broader Indo-Gangetic Plain. Located at approximately 31.08°N, 75.34°E, its relatively flat terrain, averaging around 230 meters above sea level, contributes to a unique set of challenges regarding air quality. The surrounding landscape is predominantly agricultural, characterized by expansive fields of wheat, rice, and cotton – a typical feature of Punjab’s rural economy. This intensive agricultural activity, particularly the widespread burning of crop residue after harvest, is a major contributor to seasonal pollution spikes. Shāhkot’s proximity to the Malwa region, known for its intensive farming practices, exacerbates this issue. While not directly adjacent to any major river, the town benefits from groundwater resources crucial for irrigation, further supporting the agricultural dominance. The urban–rural gradient around Shāhkot is gradual, with smaller villages and agricultural land seamlessly blending into the town’s periphery. The lack of significant natural barriers, such as hills or forests, allows pollutants to accumulate, especially during periods of stagnant air. Furthermore, Shāhkot’s location within a densely populated region of India means it is susceptible to transboundary pollution, receiving pollutants from neighboring cities and industrial areas. The relatively low elevation and flat topography limit atmospheric dispersion, trapping pollutants close to the ground and intensifying their impact on local air quality. The region's climate, characterized by hot summers and cool winters, also influences atmospheric stability and pollutant behavior.

Shāhkot’s air quality follows a distinct seasonal pattern heavily influenced by agricultural practices and meteorological conditions. The post-monsoon season (October-November) is notoriously the most challenging, marked by severe pollution episodes. This period coincides with the burning of crop residue – a practice known as stubble burning – to quickly clear fields for the next planting season. The prevailing meteorological conditions during this time, including temperature inversions and calm winds, trap the smoke and particulate matter close to the ground, leading to hazardous air quality. Winter months (December-February) continue to experience elevated pollution levels, although slightly less intense than the peak burning season, due to cooler temperatures and persistent fog, which further restricts atmospheric mixing. The monsoon season (July-September) brings a period of relative relief, as rainfall washes away pollutants and strong winds disperse them. However, even during the monsoon, localized pollution from vehicle emissions and industrial activity can still occur. The pre-monsoon season (March-June) sees a gradual increase in pollution as temperatures rise and winds become less frequent. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise extreme caution during October and November, minimizing outdoor activity and using air purifiers when possible. During the winter months, indoor air quality is also a concern, and proper ventilation is crucial. The monsoon offers the best window for outdoor activities, but vigilance regarding localized pollution sources remains important. Public health advisories are frequently issued during peak pollution periods, emphasizing the importance of mask usage and limiting exposure.
