Qorasuv, nestled in the fertile Andijon Valley of Uzbekistan, occupies a geographically significant position at coordinates 40.7222° N, 72.8872° E. The city, home to approximately 33,000 residents, is situated on relatively flat terrain characteristic of the valley floor, with a modest elevation contributing to basin-like air stagnation potential. The surrounding landscape is dominated by intensive agricultural lands, primarily cotton fields, a defining feature of the region’s economy and a key factor influencing local air quality. Qorasuv isn’t directly adjacent to a major body of water, though the Andijon River flows nearby, providing irrigation but also potentially contributing to humidity and localised fog formation. The urban-rural gradient is sharp; Qorasuv transitions quickly into surrounding agricultural villages and farmland. While not a major industrial hub itself, Qorasuv’s proximity to larger industrial centres within the Andijon region means it can experience transboundary pollution. Dust from agricultural practices, particularly during harvest and land preparation, is a consistent contributor to particulate matter. The valley’s topography, enclosed by mountains to the south and east, limits air circulation, exacerbating pollution episodes. This geographical setting creates a unique microclimate prone to trapping pollutants, especially during periods of low wind speed.

Qorasuv experiences a continental climate with distinct seasons, profoundly impacting air quality. Spring (March-May) sees increasing agricultural activity, leading to a rise in dust and particulate matter from field preparation. Temperatures begin to warm, potentially triggering temperature inversions that trap pollutants near the ground. Summer (June-August) is typically drier, with hot temperatures and infrequent rainfall. While winds can offer some dispersion, heat exacerbates ozone formation. Autumn (September-November) is often the most challenging period. Cotton harvesting generates significant dust pollution, and the onset of cooler temperatures and stable atmospheric conditions increases the likelihood of smog formation. November frequently experiences dense fogs, trapping pollutants and reducing visibility. Winter (December-February) brings cold temperatures and occasional snowfall. Heating with coal and wood in residential areas becomes prevalent, contributing to elevated levels of particulate matter and sulfur dioxide. Sensitive groups – children, the elderly, and those with respiratory conditions – should limit outdoor activity during autumn and winter. Spring can also pose risks due to pollen and dust. Favour outdoor activity during windy summer afternoons, but be mindful of ozone levels.
