Yellāreddi, a small town in the Nalgonda district of Andhra Pradesh, India, sits at coordinates 18.1859°N, 78.0212°E. The terrain is largely characterised by the Deccan Plateau, presenting a gently undulating landscape. The town’s elevation is relatively low, contributing to limited natural dispersion of pollutants. Yellāreddi is not directly adjacent to a major body of water, though smaller streams and tanks (reservoirs) are present, influencing local humidity. The surrounding region is predominantly agricultural, with paddy cultivation being prominent, alongside some cotton and other seasonal crops. This agricultural activity contributes to particulate matter pollution through practices like crop residue burning. While Yellāreddi itself isn’t a major industrial hub, its proximity to larger towns and cities with industrial activity, like Hyderabad, means it can experience pollutant transport. The urban-rural gradient is quite sharp; the town is a relatively concentrated settlement amidst a largely rural backdrop. This creates a localised pollution ‘bowl’ effect, where emissions struggle to dissipate. Road dust from unpaved roads and vehicle emissions within the town further exacerbate the situation. The local geology, consisting of weathered granite and laterite soils, also contributes to dust generation, particularly during drier periods. Understanding this geographical context is crucial for addressing Yellāreddi’s air quality challenges.

Yellāreddi experiences a tropical climate, with distinct wet and dry seasons heavily influencing air quality. The dry season, roughly from November to May, sees consistently poorer air quality. Lower humidity and stagnant air masses allow pollutants to accumulate. January and February are typically the worst months, with temperature inversions trapping emissions near the ground. Dust from agricultural fields and construction activities is also prevalent during this period. The onset of the monsoon in June brings a significant, though often temporary, improvement. Heavy rainfall washes away particulate matter, and increased wind speeds aid dispersion. However, increased humidity can also promote the formation of secondary pollutants. Post-monsoon, from September to November, sees a gradual deterioration as the rains subside and agricultural burning increases in preparation for the next planting season. October is often a transition month with fluctuating conditions. 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 is cleaner, the risk of waterborne diseases increases, requiring caution. Fog can also occur during cooler months, exacerbating particulate matter concentrations.
