Mundi, a small city nestled within the heart of Madhya Pradesh, India, occupies a geographically significant position at approximately 22.07°N latitude and 76.50°E longitude. The terrain surrounding Mundi is largely characterised by the undulating landscapes of the Satpura Range foothills, contributing to a varied topography. The city itself sits at an elevation of roughly 350 meters above sea level, influencing local wind patterns and pollutant dispersion. While not directly adjacent to a major river, Mundi benefits from seasonal streams and groundwater resources vital for agriculture. The surrounding region is predominantly rural, dominated by agricultural lands cultivating crops like wheat, rice, and pulses. However, increasing industrial activity in nearby districts, particularly related to mining and processing of forest products, is beginning to exert an influence on the regional air quality. The urban-rural gradient is relatively sharp, with a noticeable shift in air quality as one moves away from the concentrated human activity within Mundi. Dust from agricultural practices and unpaved roads contributes significantly to particulate matter levels, exacerbated by the region’s semi-arid climate. The city’s location within a valley can also trap pollutants, particularly during periods of calm weather, hindering natural ventilation and impacting air quality.

Mundi experiences a distinct seasonal air quality pattern dictated by the monsoon and post-monsoon periods. The summer months (March-May) see a build-up of dust and particulate matter due to dry conditions and agricultural activity, often coupled with stagnant air. Temperatures soar, potentially leading to ground-level ozone formation. The arrival of the monsoon (June-September) brings a temporary respite, with rainfall effectively washing away pollutants and increasing humidity, suppressing dust. However, increased cloud cover can also contribute to temperature inversions, trapping pollutants near the ground. Post-monsoon (October-November) is often the worst period for air quality, as cooler temperatures and calmer winds allow pollutants from agricultural burning and local industries to accumulate. Winter (December-February) sees cool, dry conditions and frequent fog, exacerbating particulate matter concentrations. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during October-November and December-February. Avoiding peak hours near roadways and construction sites is advisable year-round. Monitoring local weather reports and being mindful of personal health are crucial for mitigating exposure.
