Purushottampur, nestled in the Ganjam district of Odisha, India, occupies a geographically significant position along the Bay of Bengal coastline. Located at approximately 19.52°N, 84.88°E, the town’s terrain is predominantly flat, characteristic of the fertile deltaic plains formed by the Rushikulya River. This river, a vital waterway, influences the local microclimate and contributes to the area’s agricultural productivity, primarily rice cultivation and horticulture. The surrounding landscape is a mosaic of agricultural fields, interspersed with small villages and patches of coastal vegetation. The urban–rural gradient is relatively gradual, with agricultural land extending close to the town’s periphery. Purushottampur’s proximity to the Bay of Bengal introduces a maritime influence, moderating temperatures and increasing humidity. However, it also makes the town susceptible to coastal winds and occasional saline intrusion, impacting soil quality and potentially contributing to particulate matter deposition from marine sources. While Purushottampur itself lacks major heavy industries, it lies within a region experiencing increasing agricultural intensification, which can lead to emissions from fertilizer use and biomass burning during crop residue management. The relatively low elevation (around 10-20 meters above sea level) limits atmospheric dispersion, potentially trapping pollutants under certain meteorological conditions. The town’s location within a densely populated coastal belt means that regional pollution sources, including those from larger industrial centers further inland, can impact air quality.

Purushottampur’s air quality follows a distinct seasonal pattern dictated by the region’s tropical monsoon climate. The monsoon season, typically spanning from June to September, brings relief from accumulated pollutants due to frequent rainfall and strong onshore winds that effectively flush out particulate matter. Humidity levels are high during this period, which can exacerbate respiratory issues for some individuals. The pre-monsoon months (March-May) often witness a concerning rise in air pollution, driven by increasing temperatures and decreasing rainfall. This period is frequently characterized by stagnant air and the potential for temperature inversions, trapping pollutants close to the ground. Agricultural practices, including the burning of crop residue after the harvest, significantly contribute to this pollution spike. The post-monsoon season (October-November) sees a gradual improvement in air quality as rainfall decreases, but the risk of biomass burning persists. Winter months (December-February) are generally cooler, with periods of dense fog, which can severely restrict visibility and trap pollutants, leading to localized air quality degradation. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during the pre-monsoon and winter months, limiting outdoor activities during peak pollution episodes. Maintaining indoor air quality through ventilation and air purification can also be beneficial. The impact of the Bay of Bengal’s winds is crucial; consistent onshore breezes generally help disperse pollutants, but periods of calm can lead to stagnation and increased concentrations.
