Petlāwad, nestled in the heart of Madhya Pradesh, India, occupies a geographically significant position within the Malwa Plateau. Located at approximately 23.0108° N latitude and 74.7961° E longitude, the town’s elevation of around 318 meters above sea level contributes to a relatively stable atmospheric layer, which can, at times, exacerbate pollution accumulation. The surrounding landscape is predominantly characterized by undulating plains and agricultural fields, a typical feature of the Malwa region. This proximity to intensive agricultural zones means that seasonal burning of crop residue, a common practice after harvests, significantly impacts Petlāwad’s air quality. The town sits on the edge of an urban–rural gradient, experiencing a gradual transition from denser settlements to expansive farmland. While Petlāwad itself is a relatively small town with a population of 15,175, it’s situated within a broader network of smaller towns and villages, and is not directly adjacent to major industrial belts. However, the region’s reliance on agriculture and the potential for localized brick kilns and small-scale industries contribute to localized pollution sources. The absence of major rivers or lakes in the immediate vicinity limits natural air purification processes, further influencing the town’s air quality dynamics. The plateau’s topography, while generally flat, can create localized wind patterns that sometimes trap pollutants, particularly during periods of low wind speed. The climate, characterized by hot summers and mild winters, also plays a role in how pollutants disperse or accumulate.

Petlāwad’s air quality follows a distinct seasonal pattern dictated by the region’s monsoon climate. The pre-monsoon months (March-May) typically experience the poorest air quality. High temperatures and low wind speeds create conditions conducive to temperature inversions, trapping pollutants close to the ground. Agricultural burning intensifies during this period as farmers clear fields after the winter harvest, releasing substantial amounts of particulate matter. The monsoon season (June-September) brings relief, with increased rainfall and stronger winds that effectively flush out pollutants. However, heavy rainfall can also lead to increased humidity and the formation of ground-level ozone under certain conditions. Post-monsoon (October-November) sees a gradual return to drier conditions, and a resurgence of agricultural burning, though generally less intense than in the pre-monsoon period. Winter months (December-February) are generally the most pleasant, with cooler temperatures and more frequent wind, aiding in pollutant dispersion. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the pre-monsoon months, limiting outdoor activities during peak pollution episodes. Even during the monsoon, those with asthma or other respiratory ailments should monitor local conditions. The dry winter air can also irritate respiratory systems, so maintaining adequate hydration is crucial. Public health advisories are often issued during periods of elevated pollution, recommending reduced outdoor exertion and the use of air purifiers indoors.
