Mahuākherāganj, nestled in Uttar Pradesh, India (29.1300° N, 78.9200° E), presents a unique geographic profile significantly influencing its air quality. Situated within the Indo-Gangetic Plain, the city experiences a predominantly flat terrain, characteristic of the alluvial landscape formed by the Yamuna River and its tributaries. The surrounding region is a mosaic of agricultural land, primarily dedicated to wheat and rice cultivation, interspersed with small villages and scattered industrial units. This agricultural belt contributes to seasonal particulate matter, particularly during harvest periods when stubble burning is prevalent. Mahuākherāganj’s location, relatively distant from major urban centers like Agra, mitigates some of the direct urban pollution impacts, but it remains susceptible to regional transport of pollutants from larger industrial hubs further north and west. The elevation is low, averaging around 170 meters above sea level, which, combined with the flat topography, can exacerbate the trapping of pollutants, especially during periods of temperature inversion. While not directly adjacent to a major river, the proximity to the Yamuna basin influences local weather patterns and humidity levels, which can affect the dispersion of airborne contaminants. The urban–rural gradient around Mahuākherāganj is gradual, with agricultural activities steadily transitioning into residential areas, creating a complex interplay between rural and urban pollution sources. The lack of significant natural barriers further limits the city’s ability to naturally filter or disperse pollutants.

Mahuākherāganj's air quality follows a distinct seasonal pattern dictated by the region's monsoonal climate. The dry season, spanning roughly October to May, is characterized by significantly poorer air quality. November and December often see the worst conditions, coinciding with post-harvest agricultural practices involving widespread crop residue burning. This releases substantial amounts of particulate matter, significantly impacting visibility and respiratory health. Temperature inversions, common during these colder months, trap pollutants close to the ground, further intensifying the problem. January and February are typically the coldest months, with frequent fog episodes that exacerbate the issue by reducing pollutant dispersion. The monsoon season (June to September) brings a welcome respite, with rainfall washing away pollutants and strong winds dispersing remaining contaminants. However, even during the monsoon, localized pollution from construction activities and vehicular emissions can still occur. The transition months of March-May see a gradual increase in temperature and decreasing rainfall, leading to a slow deterioration in air quality as the dry season approaches. Sensitive groups, including children, the elderly, and individuals with pre-existing respiratory conditions, should exercise caution during the dry season, particularly during periods of stubble burning and fog. Outdoor activities should be limited, and the use of air purifiers and masks is recommended. The monsoon months offer the most favorable conditions for outdoor recreation, though vigilance regarding localized pollution sources remains important.
