Balāngīr, nestled in the western region of Odisha, India, occupies a unique geographic position within the undulating terrain of the Eastern Ghats. Situated at coordinates 20.7200°N, 83.4800°E, the city’s elevation contributes to localized weather patterns and influences air dispersion. The surrounding landscape is predominantly rural, characterized by agricultural lands – primarily rice paddies – and forested hills. The Mahanadi River basin lies to the east, though Balāngīr itself isn’t directly on the river, its tributaries influence local humidity. While not a major industrial hub, Balāngīr serves as a regional trading center for agricultural produce, leading to increased vehicular traffic and localized dust emissions. The urban-rural gradient is quite sharp; the city core quickly transitions to agricultural fields and forested areas. This proximity to agricultural practices introduces seasonal biomass burning, a significant contributor to particulate matter. The terrain, with its hills and valleys, can trap pollutants during periods of calm winds, exacerbating air quality issues. The city’s location within a rain shadow area can also lead to drier conditions during certain periods, increasing dust suspension. Understanding this interplay of geography and activity is crucial for addressing Balāngīr’s air quality challenges.

Balāngīr experiences a distinct wet and dry season, heavily influencing its air quality. The dry season, from November to April, sees consistently poorer air quality. Lower humidity and stagnant air masses allow pollutants from vehicular emissions, construction, and biomass burning to accumulate. January and February are typically the worst months, with temperature inversions trapping pollutants near the ground. The monsoon season, arriving in June and lasting until September, brings significant relief. Heavy rainfall effectively washes away particulate matter, and increased wind speeds disperse pollutants. However, increased humidity can also promote the formation of secondary pollutants. October marks a transitional period, with decreasing rainfall and a gradual build-up of pollutants. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the dry season, particularly January-February. During the monsoon, while air quality improves, the risk of waterborne diseases increases, requiring caution. Post-monsoon, the burning of crop residue contributes to a temporary spike in particulate matter. Overall, the monsoon months offer the most favourable conditions for outdoor activity.
