Mulug, nestled in the Warangal district of Andhra Pradesh, India, occupies a geographically significant position within the Deccan Plateau. Located at approximately 18.1910° N latitude and 79.9430° E longitude, the town’s elevation averages around 450 meters above sea level, contributing to a generally temperate climate. The surrounding landscape is characterized by undulating hills and valleys, typical of the Telangana region, with pockets of dense vegetation and agricultural land. Mulug sits on the fringes of a predominantly rural area, exhibiting a gradual urban–rural gradient as one moves outwards. While not directly adjacent to a major river, the Kadem River flows nearby, influencing local humidity and microclimates. The town’s proximity to the industrial belt around Warangal, though not immediately within it, means it can be susceptible to pollutants transported by prevailing winds. Agricultural practices in the surrounding areas, including the burning of crop residue after harvest, are a potential source of particulate matter. The terrain itself, with its varied topography, can create localized areas of stagnant air, particularly during periods of low wind speed, exacerbating air quality issues. The relatively small population of 12,135 suggests a primarily agrarian economy, with limited heavy industry within Mulug itself, though the regional context introduces external pollution influences. The geological composition of the Deccan Plateau, largely basaltic rock, can also influence the dispersion of pollutants, potentially leading to their persistence in the atmosphere.

Mulug’s air quality follows a distinct seasonal pattern dictated by the region’s tropical climate, exhibiting a clear wet and dry season cycle. The dry season, typically spanning from March to June, often witnesses a noticeable decline in air quality. This period is characterized by high temperatures, low humidity, and frequently, stagnant air conditions. Temperature inversions, where a layer of warm air traps cooler air near the ground, are common, preventing the vertical dispersion of pollutants. Agricultural burning, a widespread practice to clear fields for the next planting season, significantly contributes to particulate matter pollution during these months. April and May are generally the most challenging months for air quality. The onset of the monsoon season, usually in July, brings a welcome respite. Rainfall effectively washes away pollutants, and increased wind speeds facilitate their dispersal. August and September see a marked improvement in air quality. The post-monsoon season (October-November) can experience periods of fog, particularly in the mornings, which traps pollutants near the ground, leading to temporary spikes in localized air quality concerns. December and January are relatively mild, with cooler temperatures and moderate wind speeds, generally resulting in acceptable air quality. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the dry season, limiting outdoor activities during peak pollution periods and ensuring adequate ventilation indoors. Maintaining awareness of local weather patterns and agricultural practices is crucial for informed decision-making regarding outdoor exposure.
