Qumqo‘rg‘on, nestled within the Surxondaryo Region of Uzbekistan, occupies a strategically important position in the southwest of the country, bordering Afghanistan. Its coordinates (37.8278, 67.5972) place it within a landscape dominated by the Kyzylkum Desert’s southern fringes, transitioning into a more fertile, alluvial plain along the Murghob River. The city sits at an elevation of approximately 530 meters (1,739 feet), contributing to a generally drier climate and influencing atmospheric stability. The surrounding terrain is characterized by gently rolling hills and valleys, with the Pamir-Alay mountain range looming distantly to the south, impacting regional wind patterns. This proximity to the desert means that Qumqo‘rg‘on experiences frequent dust storms, a significant contributor to particulate matter pollution. The urban character is relatively compact, reflecting its smaller population of around 14,900. Agriculture plays a vital role in the regional economy, with cotton and fruit orchards prevalent in the surrounding areas. This agricultural activity, particularly the use of fertilizers and pesticides, can contribute to localized air pollution. Further afield, industrial zones are less prominent than in larger Uzbek cities, but smaller-scale processing facilities related to agriculture are present. The urban-rural gradient is relatively sharp, with the city quickly giving way to agricultural land and desert scrub, impacting the dispersion of pollutants and creating potential for localized hotspots. The Murghob River, while a source of water, can also contribute to humidity and fog formation under certain conditions, affecting pollutant mixing.

Qumqo‘rg‘on’s air quality follows a distinct seasonal pattern dictated by its semi-arid climate. Spring (March-May) often brings increased dust and sand intrusion from the Kyzylkum Desert, exacerbated by strong winds associated with the transition period. This leads to elevated particulate matter levels, particularly during windy days. Summer (June-August) is typically the hottest and driest period, with high temperatures often leading to temperature inversions, trapping pollutants near the ground, especially in the evenings. Agricultural burning, a common practice for clearing fields, can also significantly worsen air quality during this time. Autumn (September-November) sees a gradual decrease in temperatures and wind speeds, but dust events can still occur. The cooler temperatures can also lead to increased fog formation, which, while reducing visibility, can also trap pollutants. Winter (December-February) generally offers the best air quality, with cooler temperatures and occasional rainfall helping to disperse pollutants. However, periods of calm weather and temperature inversions can still lead to localized pollution episodes. Sensitive groups, including children, the elderly, and individuals with respiratory conditions, should limit outdoor activity during spring dust storms and summer heatwaves. Agricultural workers should be particularly mindful of exposure to pesticides and fertilizers. Residents are advised to monitor local weather forecasts and air quality reports, and to take precautions such as wearing masks during periods of high dust or pollution.
