Attock Khurd, nestled in the Punjab province of Pakistan (33.7667° N, 72.3667° E), occupies a strategically important location within the broader Indus Plain. The city’s geography is characterized by a gently undulating terrain, transitioning from the fertile plains to the foothills of the Potohar Plateau to the north. This proximity to the plateau influences local weather patterns and contributes to the potential for temperature inversions, a key factor in air quality. Attock Khurd sits approximately 180 meters above sea level, a moderate elevation that impacts atmospheric mixing. The surrounding landscape is predominantly agricultural, with extensive fields of wheat, cotton, and sugarcane dominating the rural areas. This agricultural activity, while vital to the regional economy, contributes to seasonal particulate matter pollution through crop residue burning, particularly during the post-harvest period. To the east, the city is within reach of industrial belts concentrated around Rawalpindi and Islamabad, introducing emissions from manufacturing and transportation. The urban–rural gradient is relatively sharp, with Attock Khurd exhibiting a mix of residential areas and small-scale industries. The nearby Haro River, though not directly adjacent to the city center, influences local humidity and can affect the dispersion of pollutants. The city’s position within a relatively enclosed basin, coupled with its agricultural and industrial surroundings, creates conditions that can trap pollutants and exacerbate air quality challenges, especially during periods of stagnant air.

Attock Khurd’s air quality experiences a distinct seasonal cycle heavily influenced by regional weather patterns. Winter (November to February) typically presents the most challenging conditions. Cold temperatures lead to frequent temperature inversions, where a layer of warm air traps cooler air near the ground, preventing pollutants from dispersing. Dense fog, common during these months, further restricts visibility and concentrates particulate matter. Agricultural burning after the harvest of crops like rice and wheat significantly contributes to this pollution load. Spring (March to May) brings a gradual improvement as temperatures rise and winds increase, aiding in pollutant dispersion. However, dust storms originating from the Cholistan Desert to the south can occasionally impact air quality. The monsoon season (June to September) generally offers a respite, with rainfall washing away pollutants and increased wind speeds promoting ventilation. However, heavy rainfall can also lead to localized flooding and the release of pollutants from stagnant water sources. Autumn (October) sees a return to cooler temperatures and calmer winds, with a gradual increase in pollution levels as the winter season approaches. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should exercise caution during the winter months, limiting outdoor activity on days with poor visibility or noticeable odors. During the monsoon, while overall air quality improves, be mindful of potential waterborne illnesses. Throughout the year, maintaining indoor air quality through ventilation and air purification can offer some protection.
