Jangipur, West Bengal, occupies a geographically significant position within the Ganges Delta, a vast alluvial plain shaped by the mighty Ganges River. Located at approximately 24.4691° N, 88.1032° E, the city’s terrain is remarkably flat, typical of the deltaic landscape, with an average elevation hovering around 12 meters above sea level. This low elevation contributes to a tendency for stagnant air conditions, particularly during cooler months, exacerbating pollution accumulation. The surrounding landscape is predominantly agricultural, characterized by fertile fields cultivated with rice, jute, and other crops – a vital economic driver but also a potential source of seasonal biomass burning contributing to particulate matter. Jangipur sits on the banks of the Hooghly River, a distributary of the Ganges, which influences local humidity and temperature patterns. While the river offers some degree of natural air cleansing through deposition, its proximity to industrial activity upstream can also introduce pollutants. The urban–rural gradient around Jangipur is gradual; the city blends seamlessly into the agricultural hinterland, with smaller villages and agricultural plots defining the immediate periphery. Further afield, the industrial belt of West Bengal, concentrated around Kolkata and its surrounding districts, exerts an indirect influence, occasionally transporting pollutants via prevailing wind patterns. The flat topography and deltaic setting, combined with agricultural practices and regional industrial influences, create a complex interplay of factors impacting Jangipur's air quality.

Jangipur’s air quality follows a distinct seasonal pattern dictated by the region’s monsoon climate. The monsoon season, typically spanning June to September, brings relief from accumulated pollutants due to frequent rainfall and strong winds that disperse contaminants. However, the preceding pre-monsoon months (March-May) often witness a significant deterioration in air quality. High temperatures, stagnant air, and the prevalence of fog, particularly in April, trap pollutants close to the ground, leading to increased concentrations. Agricultural burning, a common practice for clearing fields after the harvest, further contributes to particulate matter during this period. The post-monsoon season (October-November) is characterized by cooler temperatures and calmer winds, again creating conditions conducive to pollution buildup. Winter months (December-February) are generally the most challenging, with frequent temperature inversions – a phenomenon where a layer of warm air sits above cooler air, preventing vertical mixing and trapping pollutants near the surface. Outdoor activities are best avoided during early mornings in November-February due to dense fog and elevated pollution levels. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise particular caution during the pre-monsoon and winter months, limiting prolonged outdoor exposure and considering the use of air purifiers indoors. The cyclical nature of monsoon rains and the interplay of temperature and wind patterns are key drivers of Jangipur’s air quality fluctuations.
