Jalalpur Jattan, situated in the Punjab province of Pakistan at 32.6419°N, 74.2033°E, occupies a relatively flat alluvial plain characteristic of the broader Indo-Gangetic Plain. The city’s elevation is low, contributing to potential temperature inversions that trap pollutants. It’s positioned within a predominantly agricultural landscape, heavily reliant on irrigation from the Chenab River, which flows nearby, influencing local humidity and potentially contributing to dust suspension during drier periods. The surrounding terrain is largely farmland, dominated by wheat, rice, and sugarcane cultivation. This agricultural intensity leads to seasonal burning of crop residue, a significant source of particulate matter. Jalalpur Jattan is not a major industrial hub itself, but its proximity to larger industrial areas in Gujranwala and Sialkot means it experiences transboundary pollution. The urban-rural gradient is fairly sharp; the city centre is densely populated, while the immediate surroundings are rural and agricultural. This creates localized pollution hotspots within the city, exacerbated by traffic congestion and domestic fuel burning. The lack of significant natural barriers to air flow means pollutants can accumulate easily, particularly during stable atmospheric conditions. The city’s geography, therefore, predisposes it to air quality challenges.

Jalalpur Jattan experiences a distinct seasonal air quality pattern. The winter months (November to February) are typically the worst, characterized by frequent temperature inversions and stagnant air. Cold, dense air becomes trapped near the ground, preventing pollutants from dispersing, and increased reliance on solid fuel for heating exacerbates the problem. Dense fog further reduces visibility and traps pollutants. Spring (March-May) sees a gradual improvement as temperatures rise and winds pick up, but crop burning begins, introducing significant particulate matter. The summer monsoon (June-September) offers a temporary respite, with rainfall washing pollutants from the air and stronger winds aiding dispersion. However, increased humidity can also promote secondary pollutant formation. October is a transitional month, with declining monsoon influence and the start of post-harvest crop residue burning. Sensitive groups – children, the elderly, and those with respiratory conditions – should avoid prolonged outdoor activity during winter and spring. Monitoring wind direction during crop burning is crucial. The best time for outdoor activity is generally during and immediately after the monsoon season. Staying indoors on heavily polluted days and using air purifiers are recommended.
