Risod, a municipality in Washim district of Maharashtra, India, occupies a relatively flat terrain within the Deccan Plateau. Located at approximately 19.97°N latitude and 76.78°E longitude, the city sits at an elevation of around 350 meters. This positioning influences its climate and, consequently, its air quality. The surrounding landscape is predominantly agricultural, characterized by cotton, soybean, and jowar cultivation, typical of the region’s black soil plains. While not directly adjacent to a major river, Risod benefits from groundwater resources and smaller tributaries feeding into the Penganga River basin to the south. The urban-rural gradient is pronounced; Risod serves as a market centre for the surrounding agricultural villages. Industrial activity is limited, primarily consisting of agricultural processing and small-scale enterprises. However, regional transport networks, including state highways, contribute to vehicular emissions. Dust from agricultural practices, particularly during harvesting and land preparation, is a significant local source of particulate matter. The Deccan Plateau’s generally stable atmospheric conditions can exacerbate pollution build-up, especially during the drier months. The lack of significant topographical features to disperse pollutants means that emissions tend to concentrate locally, impacting air quality within and around the city.

Risod experiences a distinct seasonal air quality pattern dictated by the monsoon and post-monsoon periods. The monsoon season (June-September) generally brings improved air quality due to rainfall washing away particulate matter and suppressing dust. However, increased humidity can also foster mold growth, potentially affecting respiratory health. October-November sees a gradual deterioration as the monsoon retreats and agricultural burning increases following the harvest, releasing significant smoke and pollutants. This period often experiences stagnant air, trapping pollutants near the ground. Winter (December-February) is typically the worst period for air quality, with cooler temperatures leading to temperature inversions – a layer of warm air trapping cooler, polluted air below. Low wind speeds further exacerbate the problem. March-May brings rising temperatures and dry conditions, increasing dust levels from agricultural activities and unpaved roads. The pre-monsoon heat creates convective mixing, which can temporarily improve conditions, but also increases ozone formation. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the winter and post-monsoon months. Monitoring local weather patterns and avoiding peak pollution times is advisable.
