Mirialguda, nestled in the Nalgonda district of Andhra Pradesh, India, occupies a central position within the Deccan Plateau. Located at approximately 16.87°N latitude and 79.58°E longitude, the city sits at an elevation of around 170 meters (558 feet). This relatively flat terrain is characteristic of the plateau, though gentle undulations are present. The surrounding landscape is predominantly agricultural, dominated by paddy fields and cotton farms, interspersed with rocky outcrops and small hills. The city’s proximity to the Krishna River, approximately 40km to the south, influences local humidity and can contribute to temperature moderation. While not directly within a major industrial belt, Mirialguda serves as a regional trading hub for agricultural produce, leading to increased vehicular traffic and localised dust emissions. The urban-rural gradient is quite pronounced; the city core experiences higher population density and commercial activity, while the periphery transitions rapidly into rural farmland. This gradient impacts air quality, with concentrated emissions in the city centre and dispersed agricultural dust in surrounding areas. The Deccan Plateau’s geological composition, rich in limestone, also contributes to particulate matter in the air, particularly during dry periods when soil is easily eroded. The city’s location, shielded by the plateau, can sometimes trap pollutants, exacerbating air quality issues.

Mirialguda experiences a tropical climate with distinct wet and dry seasons, heavily influencing its air quality. The dry season, from November to May, sees consistently poorer air quality. Lower humidity and higher temperatures promote dust suspension from agricultural activities and unpaved roads. January and February are typically the clearest months, but as temperatures rise towards summer, stagnant air masses and temperature inversions trap pollutants near the ground. The monsoon season, arriving in June and lasting until September, brings temporary relief. Heavy rainfall washes away particulate matter, improving air quality significantly. However, increased humidity can also foster mold growth, impacting respiratory health. October marks a transition period, with decreasing rainfall and a gradual return to drier conditions, and a corresponding decline in air quality. November often sees a spike in pollution due to post-monsoon crop residue burning. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during the peak of the dry season (March-May) and be mindful of potential irritants during the post-monsoon period. Monitoring local weather patterns and avoiding peak traffic hours can further mitigate exposure.
