Lakhipur, nestled in the sprawling district of Bishnupur in West Bengal, India, occupies a geographically significant position within the fertile Gangetic plains. Located at approximately 26.33° N latitude and 88.39° E longitude, the town’s elevation hovers around 20 meters (66 feet) above sea level, contributing to a relatively flat terrain characteristic of the region. The surrounding landscape is predominantly agricultural, a patchwork of rice paddies, jute fields, and vegetable farms, reflecting the area’s strong agrarian economy. The proximity to the Barak River, though not directly adjacent, influences the local microclimate and humidity levels. Lakhipur sits within a gradual urban–rural gradient; while it exhibits a distinct urban character with a developing market area and residential zones, it remains closely intertwined with the surrounding rural communities. The town’s location within the broader Bengal Basin means it’s susceptible to atmospheric conditions common to the region, including seasonal humidity and potential for stagnant air masses. While not situated directly within a major industrial belt, the presence of smaller-scale agricultural processing units and transport corridors can contribute to localized pollution sources. The flat topography limits natural air dispersion, potentially trapping pollutants, especially during periods of low wind speed. The regional climate, dominated by a monsoon season and hot, dry periods, significantly impacts the transport and deposition of airborne particles, influencing the overall air quality profile of Lakhipur.

Lakhipur’s air quality experiences a distinct seasonal cycle dictated by the region’s monsoonal climate. The pre-monsoon months (March-May) typically see the poorest air quality, characterized by rising temperatures and decreasing humidity. This period often brings stagnant air conditions, exacerbated by the build-up of dust and agricultural residue burning in surrounding fields, a common practice for land preparation. Temperature inversions, where cooler air is trapped beneath warmer air, are also more frequent, preventing vertical mixing and trapping pollutants near the ground. The monsoon season (June-September) brings a welcome respite, with frequent rainfall washing away particulate matter and strong winds dispersing pollutants. However, heavy rainfall can also lead to increased humidity and the release of biogenic volatile organic compounds (BVOCs) from vegetation. Post-monsoon (October-November) sees a gradual return to drier conditions, with a potential for increased dust levels and a resurgence of agricultural burning. Winter months (December-February) are generally cooler, with periods of dense fog, which can trap pollutants and reduce visibility. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the pre-monsoon and post-monsoon periods, limiting outdoor exertion and monitoring for respiratory irritation. Maintaining indoor air quality through ventilation and air purification can also be beneficial. The agricultural cycle significantly influences air quality, making awareness of burning practices crucial for public health.
