Khānpur, nestled in the heart of Uttar Pradesh, India, occupies a geographically significant position within the Indo-Gangetic Plain. Located at approximately 28.53°N, 78.05°E, the city’s terrain is predominantly flat, characteristic of the alluvial plains formed by the Yamuna River and its tributaries. The surrounding landscape is a mosaic of agricultural fields – primarily wheat and sugarcane – interspersed with small villages and scattered groves of trees, creating a gradual urban-rural gradient. Khānpur’s elevation is relatively low, around 170 meters above sea level, contributing to atmospheric stability and potential for pollutant accumulation. While not directly adjacent to a major river, the proximity to the Yamuna basin influences regional weather patterns and moisture content, which can impact pollutant dispersion. The city’s regional position places it within a broader industrial belt extending across northern India, with nearby urban centers contributing to regional pollution transport. The flat topography and limited natural barriers exacerbate the impact of emissions from both local sources – primarily vehicular traffic and small-scale industries – and those transported from distant industrial zones. The surrounding agricultural practices, including the burning of crop residue after harvest, significantly contribute to seasonal particulate matter pollution. The lack of significant elevation changes hinders the natural vertical mixing of air, further compounding air quality challenges. The urban character of Khānpur is developing, with a mix of traditional housing and newer constructions, often lacking green spaces, which further limits air purification.

Khānpur’s air quality follows a distinct seasonal pattern dictated by regional meteorology and agricultural practices. The dry, cool months of November through February present the most challenging period. Temperature inversions are common during this time, trapping pollutants near the ground and leading to stagnant air conditions. Agricultural burning, a widespread practice following the harvest of crops like wheat and mustard, releases substantial amounts of particulate matter, significantly degrading air quality. Fog, frequently occurring during these months, further restricts visibility and exacerbates the impact of pollutants. March to May marks the transition to the pre-monsoon season, characterized by rising temperatures and increased dust from construction activities and road traffic. While winds generally increase, they are often erratic, leading to intermittent periods of poor air quality. The arrival of the monsoon season, typically in June, brings a welcome respite. Rainfall effectively washes pollutants from the atmosphere, and increased wind speeds facilitate dispersion. July and August generally experience improved air quality, although humidity levels remain high. The post-monsoon period, from September to October, sees a gradual return to drier conditions, with a slow increase in pollutant concentrations. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the winter months (November-February) and avoid prolonged outdoor exposure. During the pre-monsoon season, limiting strenuous activity during peak traffic hours is advisable. Maintaining indoor air quality through ventilation and air purification can also mitigate exposure risks.
